The main difference is the way the fuel gets ignited. In a gasoline engine, there is a spark plug connected to coils driven by the points and the distributor, that electrically generate a spark at the right time and ignite the fuel. In a diesel engine, there are no electric parts and no spark plug, and the fuel ignites simply because of heating up up by being compressed. That accounts for diesel engines being much more water-friendly, since getting the high voltage electrics of the gasoline engine wet disables it quite easily. It also accounts for diesel engines starting up harder in cold, since they need to be hot to ignite fuel, not having a spark to aid them do that.

Three Major Difference between Diesel and Gasoline Engine.
- Type of fuel it uses: Diesel fuel is a less volatile fuel than gasoline but possesses a greater number of BTU's per gallon. As a result, more total horsepower is obtained from a gallon of diesel than a gallon of gas.
- Type of Ignition: the fuel and air mixture in a gas cylinder is ignited by a spark. In a diesel engine, the mixture is ignited by the heat from compression.
- Fuel and air mixing: In a gas engine, the fuel and air mix takes place in the carburetor and the intake manifold and the fuel is ignited by a spark plug. In a diesel engine the diesel fuel is mixed with compressed air when the fuel is injected into the cylinder. Because air heats up when it's compressed, the fuel ignites.

What is the difference in bhp between petrol and diesel engines?
Both our internal combustion engines but the main difference is that a petrol engine uses spark plugs to ignite the fuel but a diesel engine has no spark plugs but instead uses compression to ignite the fuel. A diesel engine is also built much stronger than a gasoline/petrol engine. Diesel engines get better fuel mileage, last longer, and have much more torque or pulling power than a petrol engine. The only disadvantage to a diesel is the fact that it is more costly to build than a gasoline engine.
Which engine is more efficient diesel engine or gasoline engine?
Diesel engines are more efficient than gasoline engines.
Is it possible to run diesel engine by gasoline oil. if possible then afterward what will happen?
No, putting gasoline in a diesel will destroy the diesel engine.
Gasoline in diesel engine?
Gasoline engine is an internal combustion engine where a diesel is an internal compression engine. Gasoline is highly flammable and explodes when an electrical spark is applied to it where diesel explodes when it is put under pressure
