While the basic engine structure remains similar, LPG powered engines have additional parts to handle the fuel delivery and combustion process:
Fuel System:
* LPG Tank: Stores the liquefied petroleum gas (LPG).
* Vaporizer: Converts the liquid LPG into a gaseous state for combustion.
* LPG Regulator: Controls the LPG pressure before entering the engine.
* Fuel Filter: Removes impurities from the LPG before it reaches the engine.
* Fuel Lines: Carry LPG from the tank to the engine.
* LPG Injector: Injects LPG into the intake manifold or directly into the cylinders.
Engine Modifications:
* LPG Control Module: Controls the injection of LPG and its mixture with air.
* LPG Sensor: Monitors the amount of LPG in the system.
* Multi-Fuel Valve: Switches between LPG and gasoline/petrol fuel sources.
* LPG ECU: Controls the overall fuel system and manages engine functions for LPG operation.
Other Components:
* Engine Management System: Adapts engine settings for optimal performance on LPG.
* Exhaust System: Modified to handle the emissions of LPG combustion.
Important Note: Some vehicles may not have all of these components, depending on the design and age of the engine.
Working Principle:
1. LPG from the tank is vaporized and passes through the regulator to ensure proper pressure.
2. The LPG is then injected into the intake manifold or cylinders depending on the system design.
3. The LPG mixes with air and is ignited by the spark plugs, creating power.
4. The LPG Control Module and ECU control the fuel mixture and engine operation for optimal performance and emissions.
Advantages of LPG:
* More cost-effective than gasoline/petrol.
* Lower emissions compared to petrol/diesel.
* Cleaner burning, resulting in less engine wear.
Disadvantages of LPG:
* Requires additional equipment and modifications.
* Reduced engine power compared to petrol/diesel.
* May require specific maintenance and servicing.
Overall, LPG powered engines offer a viable alternative to traditional gasoline/petrol engines, with benefits in terms of cost and emissions. The additional parts and modifications are necessary to ensure proper fuel delivery and combustion.
