When you use cooking gas instead of auto in cars to what extant engine performance will decrease and is it advisable use?

Using cooking gas (LPG or Liquefied Petroleum Gas) instead of automotive gasoline in cars can lead to a decrease in engine performance. Here are some factors that contribute to this decrease:

1. Lower Energy Density: LPG has a lower energy density compared to gasoline. This means that it contains less energy per unit volume. As a result, you will need to use more LPG to produce the same amount of power as you would with gasoline.

2. Reduced Octane Rating: LPG typically has a lower octane rating than gasoline. The octane rating indicates a fuel's resistance to knocking or uncontrolled combustion in the engine. A lower octane rating can lead to engine knocking and reduced power output.

3. Leaner Air-Fuel Mixture: LPG has a higher air-to-fuel ratio requirement than gasoline. This means that more air is needed to burn LPG compared to gasoline. A leaner air-fuel mixture can lead to higher combustion temperatures and reduced engine efficiency.

4. Different Combustion Characteristics: LPG burns differently compared to gasoline. It has a slower flame speed and a wider flammability range. These differences can affect engine combustion and lead to reduced power output.

5. Engine Modifications: Using LPG in a car may require certain modifications to the engine, such as changing the fuel injectors, spark plugs, and fuel lines. These modifications can impact engine performance and efficiency.

Advisability of Use:

Whether it is advisable to use cooking gas in cars instead of automotive gasoline depends on various factors. Some considerations include:

1. Legality: In many countries and regions, it is illegal to use cooking gas in vehicles due to safety concerns. Always check local regulations before attempting to use LPG in a car.

2. Safety: LPG is a flammable gas and requires proper handling and storage. Improper use or handling can lead to accidents, fires, and injuries.

3. Engine Compatibility: Not all car engines are designed to run on LPG. Some engines may not be able to handle the higher air-to-fuel ratio and different combustion characteristics of LPG.

4. Performance and Efficiency: As mentioned earlier, using LPG can lead to reduced engine performance and efficiency. You may experience decreased power output and increased fuel consumption compared to using gasoline.

5. Cost: The cost-effectiveness of using LPG depends on various factors such as local LPG prices, fuel efficiency, and the cost of engine modifications.

Overall, it is generally not advisable to use cooking gas in cars as an alternative to automotive gasoline due to safety concerns, legal restrictions, potential engine performance issues, and reduced efficiency. If you are considering using LPG in your car, it is essential to consult with an automotive expert, check local regulations, and ensure proper safety measures are in place.
