Here's why:
* Diesel engines rely on compression ignition. They compress air to very high temperatures, which is enough to ignite the fuel injected into the cylinder.
* Spark plugs are used in gasoline engines to ignite the fuel-air mixture by creating a spark. This spark ignites the mixture and initiates the combustion process.
Key Differences:
* Fuel Ignition: Gasoline engines use spark plugs for ignition, while diesel engines use compression to ignite the fuel.
* Fuel Type: Gasoline engines use gasoline, while diesel engines use diesel fuel.
* Compression Ratio: Diesel engines have much higher compression ratios than gasoline engines.
Therefore, the statement that diesel engines use spark plugs is incorrect.
