* Different Combustion Processes: Diesel engines rely on compression ignition. The fuel is ignited by the heat generated from compressing air in the cylinders. Gasoline, on the other hand, is designed for spark ignition. It requires a spark plug to ignite the air-fuel mixture.
* Lubrication Issues: Gasoline lacks the lubricating properties of diesel fuel. Diesel fuel acts as a lubricant for the fuel injectors and other components within the engine. Gasoline's lack of lubrication can lead to rapid wear and tear, especially on the fuel injectors, which are very precisely engineered for diesel's higher pressure and viscosity.
* Poor Combustion: Gasoline's lower cetane number (a measure of how readily it ignites under compression) means it won't ignite efficiently in a diesel engine. This results in incomplete combustion, producing less power and potentially damaging the engine.
* Damage to Fuel System: The gasoline can dissolve seals and gaskets in the fuel system, leading to leaks. It can also damage the fuel injectors, which might require expensive replacement or cleaning.
* Hard Starting and Rough Running: The engine will likely have trouble starting and will run very roughly, if at all, due to the poor combustion.
In short, putting gasoline in a diesel engine is a serious mistake that can lead to extensive and costly repairs. If you accidentally put gasoline in a diesel engine, do not attempt to start the car. You should have the vehicle towed to a mechanic for professional diagnosis and repair. The fuel system will likely need to be flushed and potentially many components replaced.
