LPG CNG Injector Manufacturers introduces two types of LPG injection:

1. Operation principle of steam injection:
When the liquid propane passes through the cooling jacket, a pressure drop occurs, which causes the propane to evaporate and effectively cool the area around the supply section. This is called a refrigeration cycle and helps to keep the fuel in a liquid state under all driving conditions, regardless of the external temperature. The ejector delivers liquid propane to the intake port. It evaporates immediately after leaving the syringe. This rapidly expanding liquid cools the air entering the engine, usually producing more horsepower than the gasoline system can achieve, not to mention the inherently improved exhaust emissions known to propane.

2. Operation principle of liquid injection:
Compared with the same engine using gasoline as fuel, the LPG liquid injection system shows an increase, usually 10%. The higher octane number of LPG can be optimized by increasing the compression ratio or increasing the boost pressure, thereby increasing the balance that is conducive to LPG. Compared with gasoline, the power of the carburetor system is usually reduced by 15%. The liquid injection is far superior to vaporizers or gas injection systems-better than 5% to 20%. A major advantage of liquid injection is that it eliminates embarrassing backfires in the gas system. Multi-point LPG injection greatly reduces accelerator lag. The spark timing can be adjusted to provide the best performance of the liquid jet. Liquid injection does not need to be started or stopped on gasoline, nor does it require gasoline to counteract the higher combustion temperature. Liquefied petroleum gas remains liquid and is injected as gasoline at multiple points, thus helping the engine to start at low temperatures (approximately-40 degrees Celsius). There is no evaporator to freeze the moisture present, thereby freezing the system.
