CNG GAS KIT

The CNG Reducer supplies the CNG Gas to the Engine through a locally made Air Gas Mixture which is not supplied by the CNG Kit Manufacturer; it is then fitted on the Air Intake (Inlet Manifold) of the Engine. The CNG Gas and Air mixture is sucked by the Engine which travels through the manifold and reaches inside the engine, according to its firing order.

As there is no computer control over the flow of CNG gas into car s engine in a conventional CNG Kit, an even flow of CNG gas mixture now enters into the combustion chamber and burns with the help of the Sparks generated by the Spark plugs fitted in the Cylinder Head. If the Plugs are week then the car can Backfire, resulting in a mild explosion within the engine compartment which is released through the Air Cleaner of the car. This can often result in blowing off the Air Cleaner assembly of the car. That is why many cars are found with busted Air Cleaner assy. Another drawback is a compromise of the Engine Power (roughly 10-30%), and loss of Engine Life due to poor pick up and A/C load.

With the improvement in Engine Technologies (BS-III) little improvement in the CNG Kit technology was achieved with the introduction of Lambda Controlled System(LCS) orClose loop System & Timing Advancers(TA). A little control of the Gas flow and poor pick up can be made up with this LCS and TA that are connected with the MAP Sensor, TPS &Oxygen Sensor (Lambda sensor) fitted in the Engine & Exhaust Manifold (Silencer) of the Car.

Due to the improvement in car s pick-up with CNG Kits fitted with LCS and TA; more users started to switch to CNG from petrol and the use of A/C on CNG was more effective without compromising performance and engine s life.
