CNG station operated by SembCorp Gas
Currently, Singapore's only CNG station, operated by SembCorp Gas Pte. Ltd., is located on Jurong Island.
In addition to the current CNG station on Jurong Island, more stations are poised to be operational in the near future. The locations and dates will be announced on the website in the coming months.
A wide network of CNG stations has already been established in Malaysia. Petronas, the company who operates these Petrol/Diesel/CNG stations, has announced that the number of CNG stations will even be increased throughout the coming years.

A CNG filling station in Argentina. Galileo provides the technology and the equipment
Filling your CNG tank is done via the inner filling valve located in the front of your car where your engine is. Open the hood and you will see the red capped valve. Lift the cap open and connect the gas hose form the dispenser and it will plug in with a click. Hoses and filling valves in Singapore and Malaysia are of NGV 1 standard and universal so you will be able to refill in both countries. Filing is as similar to filling petrol.
Filling your car with CNG is safe, secure and uncomplicated. Thanks to sophisticated technology and standardized filling tubes, the filling process is as easy and fast as filling a car with Petrol. This is also dependant on the compressor pressure and refueling equipment present at the station. An advantage of using CNG is that during the refueling process, no smelly emissions are emitted. Furthermore, no spillage of lubricious liquids will appear. The fuel nozzle will be clean and tidy.
Physical attributes of CNG
If the vehicle is filled with CNG for the first time, one will soon realize, that some issues are different from the normal Petrol filling. The reason for that is very simple: CNG is in gas-form, not in liquidized form. Gas has other physical attributes than liquids have. If the cylinder is depleted and refilled with new CNG, the cylinder will get warm (not hot). This is absolutely normal and no reason to worry about. If a gas is put under pressure, the density of the molecules will increase, and therefore the temperature will rise. It will take some time, until the cylinder has adopted the temperature of its environment again.
This also has a small effect when refilling the cylinder. If a gas is heated up (the temperature increases), the pressure in that gas increases as well. The dispensers at the filling stations automatically stop dispensing CNG, once a pressure of 200 bar is reached. If a cylinder can theoretically accommodate 18 kg CNG under standard conditions (200 bar pressure, 15° Celsius), the cylinder will carry a bit less than 18 kg. Practically that means that the cooler the cylinder and the temperature around the cylinder is, the more kg of CNG can be pumped into the cylinder.
It is absolutely no problem to leave the car in the sun. This heat is never sufficient to heat up the cylinder to a critical point. The cylinders are tested and can sustain a pressure of up to 500 bar - a pressure dimension, which is usually never reached in our daily environment.
While the car is driving, a different phenomenon can be observed - the cylinder cools down. Again, this is due to the physical attributes of gases. When gas expands, the density of the molecules decreases, and the temperature drops. A nice side-effect in a warm climate like Singapore.
CNG measured in Kg
CNG is dispensed in kg (kilogram) and not in litres or m³. If one considers the above mentioned physical attributes of a gas, it becomes quickly obvious, why a measure for mass (kg) is taken instead of a measure for volume (litre or m³). One cubic metre of CNG under 10 bar pressure has just a fraction of the energy value than one cubic metre of CNG under 200 bar pressure. However, one kilogram of CNG has always the same calorific value, no matter whether it has a volume of 500 litres, or just a volume of 60 litres - under 200 bar pressure.
Depending on the size and the number of the in-built cylinder(s), the mileage of one refilling is about 150 to 300 km.
Throughout CNG popular countries, Petrol station operators such as SHELL and ESSO also operate CNG stations (see pictures).
The "box" on the right side of the Esso-picture, and the box on the roof of the Shell station is the so-called compressor. It compresses the Natural Gas of the filling station to 200 bar - exactly that pressure, which is later in the CNG tank of the car. It strongly depends on the performance of such a compressor, how fast the vehicles at a CNG station can be filled up. Modern High-Tech compressors, such as the "Microbox-110", manufactured by Galileo, can fill up several cars in just a few minutes.

What is CNG?
Compressed Natural Gas (CNG) is one of the most environment friendly alternative fuels available in the market today.
There are more than 5 million cars driving on CNG in the world today.
What is it ? The Product
The new sequential system offers better performance and reliability to the driver. This advanced system injects gas directly into the intake manifold eliminating any possibility of backfire which may damage the intake manifold. The precision injection of gas offers better fuel consumption, mileage savings and performance when compared to the mixer system. The kit reduces emissions and extends the life of catalytic converter as the ECU detects optimum combustion parameters and engine operating conditions.
How it Works
DREAM XXI P is an advanced injection system, designed for use with the latest petrol powered cars. The gas is delivered from the tank to the Pressure Regulator, that supplies it at a constant pressure to the Injection Unit. This is controlled by the Electronic Control Unit, that computes the correct gas injection timings in function of the petrol injection timings and other system parameters. Gas is injected into the intake manifold ducts in the right sequence and at the right time. The pressure stability of the regulator together with sophisticated electronic carburation control, guarantees a fast response of the system to quick power demands, and a smooth acceleration from cut-off phase. DREAM XXI P also optimizes consumption and performance.
ECU:
The new ECU grants a perfect carburation under all operating conditions. It also guarantees low fuel consumption and excellent driving performances. Designed and manufactured entirely by OMVL spa, it easily handles full-group, semi-sequential and phased sequential injection systems, with Slave and Stand Alone modes on the same board. 2 ECU versions are available: 3-4 cylindersa nd 6-8 cylinders.
The DREAM P has got complete diagnostics features and it is OBD compatible.
The ECU sports: petrol injectors emulator on board, RPM amplifier on board, Oxygen sensor emulator on board, 2 Oxygen sensors supported, suitable for CNG and LPG.
Injector RAIL:
The injection unit ensures that the right quantity of gas is delivered into the intake manifold at the intake valves. The electronic injectors are opened in the right sequence and at the right time to suit the engine's ignition cycle.
Regulator:
The pressure regulator reduces gas pressure and, in the case of the LPG, it also ensures that the liquid gas is completely vaporised. A solenoid valve shuts off the gas flow to the engine, when the engine is not operating.
Gas/Petrol Fuel Switch:
This is the electronic switch that connects to DREAM XXI P ECU. The switch allows toggling between the two fuels and sports a 5-leds level gauge showing the amount of gas remaining in the tank.
Galileo conversion kit
The Galileo conversion kit consists of several parts, which need to be built in the car.
Regulator:
The regulator is the "heart" of the CNG kit; it reduces the pressure, and supplies the CNG to the engine.
Switch:
Switch and fuel gauge in one - with this little device, the driver can chose between driving with Petrol or CNG. A small, integrated LED fuel gauge indicates how much CNG is left in the gas cylinder.
Timing Advance Processor:
Due to the fact that natural gas has different thermodynamic properties, the timing must be modified in order to adapt it to the new fuel.
Inner filling valve:
The gas is pumped through this valve when filling the cylinder.
Petrol Solenoid Valve:
Most of the cars on Singapore's roads are advanced injection engines. However, there are still some vehicles, which have a carburetted engine. No matter what kind of car you have - the Galileo Conversion Kit fits for all Petrol engines. The Petrol Solenoid Valve is one of the few parts which need to be installed additionally, if you have a carburetted car.
Gas cylinder:
The CNG is stored in the gas cylinder under 200 bar pressure. In this example, two gas cylinders are installed. It is absolutely no problem to install more than one cylinder. Doing that increases the mileage before the car needs to be refilled.
First vehicle converted!
Our first vehicle conversion was performed on 1st and 2nd of August. The car is owned by a governmental agency of Singapore.
Vehicle type: Mitsubishi
Displacement: 1.8l
Year of manufacture: 1995
The vehicle is prepared for the retrofitting. Before the installation process is carried out, a diagnosis test of the ECU is performed (only injection engines). This way, possible engine problems can easily be detected.
The Kit with all its components. It consists of several parts, such as the regulator, the timing advance processor, lambda sensor emulator, injector emulator, and a number of valves and hoses. The white pipe on the right is a high-pressure pipe. The gas flows through it with a pressure of 200 bar.
The regulator is the "heart" of the conversion kit. It reduces the pressure of the CNG coming from the cylinder from 200 bar to the operating pressure of 3 bar.
In this picture, the regulator is already fixed in the engine compartment. The thick black hose leads directly to the mixer, which is installed in front of the air-inlet of the engine.
Fuel gauge and filling valve. The instrument on the left is an analogue fuel gauge. It basically measures the gas pressure in the cylinder(s). This value is then digitalized and sent to the LED-fuel gauge, which is installed in the dashboard of the vehicle.
The Timing Advance Processor (TAP), the Injector Emulator, and the Lambda Sensor Emulator. The TAP is probably the most important electronic device of the kit. It controls the exact timing of the spark, and therefore cares for the optimal combustion of the CNG.
After the installation, various tests are performed. In this picture, the emissions of the vehicle are tested with a four-gas analyser. With this device, the vehicle can be "tuned", until the combustion reaches optimal emission values.
Dynamometer Test. With this optional test, the torque of the vehicle is measured. It can be determined at which rotation the highest torque is rendered.
During the test, the car is accelerated, and is operated in different gears.
The boot of the station wagon before the installation. The boot is big enough to accommodate some luggage.
After the installation: the cylinder is installed and tightly fixed. It weighs 67.5 kg (empty), has a capacity of 60l, which is 15 m³, has a diameter of 35 cm and is 95 cm in length.
If the cylinder should not be visible, a wooden "box" can be installed around the cylinder, in order to conceal it. This "box" is strong enough, that bags or other items can be placed on it.
Alternative Fuel - ChaNGe Fuels, Save the World!
Environmentally friendly vehicles are quite the rage nowadays. Everyone, from superstars to the regular dude on the street, is talking about it. Bio-diesel, Hybrid, CNG, Solar, electric cars all seem like the “it” words for the moment. Spearheaded by celebrities like Brad Pitt, Cameron Diaz, Ellen Degeneres and Will Ferrell, there has been no better time to talk about environmentally friendly cars than right now. I mean, if celebrities are doing their part, shouldn’t you? Now, if only they would stop jetting about in their private jets, I would be the first to commend them on being really environmentally conscious.
The current buzz in Singapore right now is CNG or Compressed Natural Gas. Taxi companies are taking the lead by installing their new fleets with a CNG system. But talk about alternative fuel to the typical boyracer wannabe and he will snap back, “GOT POWER SI BO????” Speak to the typical heartlander and you get, “These new kind of cars all expensive lor!!!! Where got worth it??” Speak to the rather informed crowd and you have this for a reply, “Only one filling station in Singapore. How is that gonna make me buy a car fitted with the CNG system?”
The concerns by these folks reflect the views of motorists in Singapore today with regards to green cars. While many would want to take the leap to do their part for the environment, they are unable to do so for they cannot make an informed decision. It does not help that the early hybrid and other green cars were sold at a considerably higher price. In Singapore, buying a car is quite a big financial deal, so people are really apprehensive about buying a car they are not familiar with.
So what is CNG?
Natural Gas is a fossil fuel that is more evenly distributed than crude oil worldwide. Compressed Natural Gas is natural gas that is stored in cylinders with pressures of up to 3600 pounds per square inch. CNG made up mostly of Methane, is lighter than air, odorless and colourless. When released into the air, it disperses quickly and will not form a rich enough mixture for combustion. In a nutshell, it will not burn easily and it is thus safer in the event of a leak.
Contrary to popular belief, CNG has a high octane level. 130, to be exact. Even Shell’s V-power does not have that much. So, theoretically, CNG should give more bang for your buck. A higher octane level also allows for higher compression ratios and improved thermal efficiency. This means lesser carbon dioxide emission into our already ailing atmosphere. CNG is also beneficial in so many other ways. 40% less Nitrous Oxide, 90% less hydrocarbons, 80% less carbon monoxide, 25% less carbon dioxide, all make for a healthier place to live in. For your information, hydrocarbons carry carcinogens, which are substances that will lead to, cancer.
Surely, you would ask, if something were really this good, it would have been used decades ago. Well, you are right. The idea of natural gas as an automotive fuel goes as far back as the 1930s. The Australians considered it an automotive fuel in 1937 and the French used it in WW1. Since then, there has been little growth in the use of natural gas, until recent times. Currently, our little island needs to quicken the pace and catch up with other countries around the world. The United States have got more than 1300 refueling stations in almost every state. Some Americans have got home refueling systems even. Compare that to our ONE refueling station and you can see what I mean when I say we are quite behind time. For a country that is always striving to the best and being a hub for everything from R&D to sports, it is quite baffling why we are not pushing the need for a betterment of our planet pertaining to vehicular emissions. Fair enough, by the end of this month, there will another one in Mandai and after that another one at Jalan Buroh. But yes, 3 stations compared to 1300 is quite a difference, to put it kindly.
Then again, 3 stations would be enough for now as the CNG system works as a compliment to the current petrol system. The car is not a dedicated CNG vehicle; you can choose to use CNG or petrol or both, all at the press of a button. The system allows you to fully run on petrol should you run out of gas. Thus, it is guaranteed that you will not be caught in a situation where you will have to push your car all the way to Jurong Island or Mandai. The system also comes with a gauge for the amount of gas left in the tank. A visit to Mandai once in a while is not so bad is it?
The loss of power is very minimal. On the Honda CRV the difference in power is probably about 5 to 10%. Acceleration from standstill was decent though the car was more aggressive on petrol. But with the amount of money saved, the minimal power loss is a small price to pay and which many would be able to live with.
So let us recap. The CNG system helps us to bring the cost of fuel down, it is less dangerous than petrol and the power loss suffered is minimal. What are you waiting for? Even with a cost of $3800 for installation of a CNG system, the savings you make will cover that initial investment and you will continue to save even more as you use the system for a longer period of time.
But before you speed off to the nearest car dealer to switch to a brand new CNG vehicle, there are some drawbacks to the whole system. The one that sticks out most (literally) would be the tank. On a Toyota Rush, the tank fills up about 70% of the entire boot. You are only left with space to put several shoes, umbrellas and maybe boxes of A4 paper. Anything bigger would be a challenge similar to a Rubick’s cube. The tank is also relatively heavy. It weighs about 66kg. So at any one point, it is like traveling with an extra passenger. The added weight means a lower power to weight ratio and an increase in fuel consumption but you still save when you use CNG by virtue of its price alone!
Some visitors to the fair organized by Pinnacle have also commented that having that tank seems dangerous. Even if the gas is almost non-combustible, it is still compressed. Should it be punctured, the tank could fly off like a Scud missile on a mission. But in my opinion, it will take quite an effort to puncture that tank for it feels and look very hardy. But still, this is the reason why LTA takes a serious view on how the installation is done. All new CNG vehicles will have to go for an inspection on the worthiness of the installation. Those that fail to comply with the guidelines will not qualify to go on the road.
So it really is up to you folks. While CNG in Singapore is still new, there is a bright future ahead for it. Soon, the tanks will get smaller and lighter and the number of refueling stations will increase. When that happens, let us all do our part in saving the environment.
Saving the cheerleader will not save the Earth. Changing fuels might. For the love of our mother earth. Peace.
DN-01 UPDATE
The DN-01 has been confirmed as a EU & UK model and UK dealers are currently taking deposits for February 08 delivery. The DN-01 is also confirmed on the Honda AU website as an Australian model. "Recommended retail to be confirmed; expected release date: second half of 2008."
The earliest any new bike would be available in the USA would be June 08 as a 2009 model but more likely it would be announced at the dealer meeting in October 08 and be on the showroom spring of 2009. However, many people suspect that the USA will never get this model as the guy running the motorcycle division of Honda America refuses to import many bikes including the Transalp which shares the same 680 engine as the DN-01.
Bike due AUSTRALIA in June/ July of '08 with a supposed price range $18-$20k
