What is CNG ?

CNG stands for Compressed Natural Gas. It is a gaseous fuel and is a mixture of hydrocarbons, main methane in the range of 95%. Due to its low density, it is compressed to a pressure of 200 bar to enhance the vehicle onboard storage capacity.

Is CNG Safe ?

Yes, it is safe. The properties of CNG make it a safe fuel. It is lighter than air, and hence in case of leakage, it disperses into the atmosphere rapidly.

Will my fuel expenses reduce after conversion to CNG?

Yes, the fuel bill on the basis of average running of vehicle reduces substantially when compared to other conventional fuels. Price of CNG is lesser than other fuels and also it enhances the mileage of your vehicle, making it the most economical fuel.

Does CNG kit require servicing ?

CNG kit is safe and simple. It gives years of trouble free operation. It doesn’t require frequent servicing. Just as for all other fuels, it is advised to have routine services. An authorized person should be consulted for service. As per Gas Cylinder Rules, 1981, the cylinder should undergo hydro-stretch testing every 3 years to check pressure tolerance.

Which type of vehicles can be converted into CNG?

All spark-ignited engines can be converted to CNG, for which a specially designed conversion kit is required for the conversion process. The kit consists of a cylinder to be fixed in the boot of the car and other equipment’s to allow gas flow into the engine.

Will I lose my boot space if I convert my car to CNG?

In case of Sedan vehicles, the vehicle owners lose about one third of their boot space when a car is converted to CNG. But in case of Hatch back the boot space is almost taken by CNG Cylinder.

Why are CNG cars more Ecological ?

Using methane as a fuel reduces the emission of the greenhouse gas CO2 by over 20%. Emissions of CO and Nitrogen Oxides (NOx) are also significantly lower. HC emissions are also almost totally made up of pure, non-toxic methane. Gas cars do not produce particulate, in particular the PM10 that are critical for urban pollution.

If i use CNG do i also have to fill up with Petrol ?

Given that the car usually starts on petrol before automatically switching over to gas, it is a good idea to always have a certain amount of petrol in your tank. For some makes of car, petrol in the tank also serves to protect the petrol pump that would deteriorate prematurely if the car were run on empty.

Is CNG environmentally friendlier than any other fuel?

Yes, it is. As CNG mainly consists of methane which is the simplest hydrocarbon, it is a much cleaner and efficient fuel. The use of CNG significantly reduces harmful exhaust gas emissions like carbon monoxide, nitrogen dioxide and sulphur dioxide which causes harmful diseases like cancer, asthma etc. CNG also helps in reducing the effects of global warming.

How does a modern CNG system work ?

The most recent technological evolution of methane, or CNG – Compressed Natural Gas – conversion systems is represented by sequential multi point fuel injection systems like the HIGHRISE EASY FAST CNG. This CNG timed sequential injection system, whereby the gas is injected into each cylinder by an injector synchronised with the cylinder’s stroke in the same way as for petrol engines, is designed for 3 to 4-cylinder engines including turbo, versions. It is also suitable for all Start & Stop system vehicles. Thanks to this technology, the EASY FAST system complies with the most recent legislation up to OBD I & OBD II. All the system components have been designed and tested at length by the HIGHRISE INTERNATIONAL Research and Development centre to guarantee maximum performance and reliability. The main components of this system are:

Filling valve:   In India the connector has a standard thread attachment, fitted with a check valve for filling the gas cylinder. mainly of the NGV – NZS type. However adaptors are available for this kind of connector. The valve can be installed in the engine compartment, on the bodywork or under the petrol flap if there is enough space.

CNG tank or Cylinder:   This is filled with gas at a pressure of about 220 bars. In its gas state, when refilling CNG is measured in Kg, referring to the molecular mass of fuel. CNG tanks are made from extremely resistant full steel or steel and fibre composites. CNG cylinders are always cylindrical in shape, their diameter and length varying to suit the vehicle.

Cylinder Valve:   A multipurpose valve fitted to the cylinder head that allows refilling of the system circuit via the filling connector.  This valve is usually fitted with heat and pressure relief valves and is tested installed on the cylinder according to strict legislation.

Reducer:   This reduces the pressure of the gas, stabilising it at the correct level for fuelling the common rail injection. It has a safety lock-off valve that closes all CNG flows when the engine is off.

Common Rail gas injection:   Controlled by the system injection electronic control unit (ECU), injectors synchronised with the engine inject the correct quantity of gas into each cylinder.

GAS/Petrol fuel-switch:   This allows the driver to switch from gas to petrol and vice versa and shows the gas cylinder level, processing the signal from a pressure gauge in the circuit and showing it on an LED display. In normal conditions, the vehicle starts on petrol and then automatically switches over to CNG, undetected by the driver, when the circuit reaches normal working conditions. Should the gas run out, the system automatically switches back to petrol and an alarm alerts the driver.

Electronic Control Unit (ECU):   The control unit interfaces with the original petrol control unit and via signals received from the system sensors controls the gas injectors, calculating times and quantities of gas to inject. The ECU is calibrated on installation to meet the vehicle’s specific characteristics and uses auto-adaptive programmes to adjust the working parameters according to variations in conditions of use and engine wear and tear.
