Petrol has a higher auto-ignition temperature, and it won't burn at the compression ratio of a diesel engine without external help. So, the engine won't run. Whereas when you use diesel in petrol engines, it's dangerous. Diesel burns with more power, and it may damage the engine partly or entirely.

Understanding the Impact of Diesel in a Petrol Engine
When diesel fuel is mistakenly supplied to a petrol engine, the consequences can be significant. Here's an explanation of why the engine will not run:
Differences Between Diesel and Petrol Fuels
- Combustion Characteristics: Diesel fuel has a higher ignition temperature compared to petrol. Petrol engines are designed to ignite fuel using spark plugs, while diesel engines rely on compression to ignite the fuel.
- Viscosity: Diesel is thicker and more viscous than petrol, making it difficult for the fuel system designed for petrol to properly atomize and mix with air.
Engine Design and Operation
- Fuel System Compatibility: Petrol engines use fuel injectors or carburetors optimized for petrol's characteristics. Diesel fuel can clog injectors and disrupt the air-fuel mixture necessary for combustion.
- Ignition Mechanism: Petrol engines rely on a spark to ignite the fuel-air mixture. Diesel won't ignite under the lower temperatures and pressures typical in a petrol engine, leading to failure to start.
Consequence of Diesel in a Petrol Engine
- Engine Failure to Start: Due to the incompatibility of diesel fuel with a petrol engine's operation, the engine will not start or run at all.
- Potential Damage: Prolonged attempts to crank the engine with diesel can cause damage to fuel injectors, pumps, and other components, leading to costly repairs.
In summary, supplying diesel fuel to a petrol engine results in the engine's failure to run due to fundamental differences in fuel properties and engine design.
