What role does a vaporizer play in an LPG powered engine?

The vaporizer is a critical component in an LPG-powered engine because it is responsible for converting liquid LPG into vapor before it enters the combustion chamber. LPG, when stored, is in a liquid state under pressure. This liquid must be converted into a gas to be mixed properly with air for efficient combustion. The vaporizer achieves this by utilizing heat from the engine or via its own heating elements to raise the temperature of the liquid LPG, enabling it to transition to a vapor phase.

This conversion is crucial because only gaseous forms of fuel can be mixed with air in the appropriate proportions needed for combustion within the engine. If the LPG did not turn into vapor, it would not burn effectively, leading to incomplete combustion, reduced power output, and potential engine performance issues. Additionally, efficient vaporization helps ensure that the engine runs smoothly and at optimal efficiency, minimizing pollutants and maximizing performance.

The other options relate to functions not associated with the primary role of the vaporizer in the context of LPG combustion systems.
