In CNG systems, the injector is supplied by the CNG fuel rail. Injection is initiated by the electronic control unit
through a signal calculated by the engine management system, ensuring precise dosing of the required gas
quantity. The NGI2 injector was developed to meet CNG operation needs, featuring an electromagnetic valve
for higher gas volume, rapid flow speed, and wear resistance, even when used with oil-free gas. Its quality and
service life are comparable to fuel injectors, with very low leakage that decreases further over its lifespan.
LPG Engine and advantages. LPG conversion kit, function, constructional details
LPG Engine: A mixture of hydrocarbons made from light petroleum is called LPG. LPG is made from propane
and butane.
LPG Liquid of Liquefied Petroleum Gas is being used as an alternative fuel for petrol engines due to the increasing
price of petrol fuel and its shortage as well as increasing pollution due to an exhaust gas.
Advantages:
1 LPG Auto gas engines have lower running costs.
2 LPG is typically less expensive than petrol or diesel.
3 Engine oil and spark plugs need changing less often with LPG vehicles, for reduced service costs.
4 Environmental benefits of LPG vehicles include reduced particulate, CO2 and NOx emissions.
Conversion kit: Converting a petrol engine to LPG engine does not require any modification to the original engine
only by using a separate LPG kit the petrol engine can be run on LPG fuel The LPG kit includes the following
1 L. P. G. Tank,
2 Multi-Function Valve,
3 High Pressure Tubing (Pipe),
4 Gas - Petrol Change Over Switch,
5 L. P. G. solenoid valve,
6 Petrol Solenoid Valve,
7 Pressure Reducer - Vaporizer,
8 Low Pressure Tubing,
10 Mixer
