The engine's pistons compress the fuel (an air and diesel oil mixture) in the cylinders and the heat generated by that compression causes the fuel to ignite.
A longer answer
Diesel engines ignite their fuel solely by means of compression: whilst spark plugs are used to ignite the gasoline fuel and air mixture in gasoline engines, in diesel engines the diesel oil and air mixture is compressed to a very much higher degree, which causes a lot of heat. The resulting very high temperature causes the fuel to self-ignite.
Diesel engines rely on heat and high compression to ignite fuel.
No #4 diesel fuel oil is for oil burners and will not ignite in a diesel egine
'Diesel' comes the German engineer, Rudoplf Diesel. Diesel invented an internal combustion engine that would auto ignite, when the fuel vapours were compressed to a high degree. This increased the temperature of the vapour to the point were it would auto ignite. The fuel that he used was slightly different from petrol, which needed an electrical spark to ignite. This slightly different fuel is now known as 'Diesel'.

The sparks plugs fire and ignite the fuel in a Gasoline engine, and compression compresses the fuel until it ignites in a Diesel engine.
because of in the diesel engine fuel injector is uses for ignite the charge & they are operated by fuel pump not to electricity and in the diesel engine there is no requirement of spark plug to genrate the spark
Yes it can if the fuel gets hot enough to ignite as in leaking on a header.
Diesel engines do not use spark plugs to ignite the fuel. Instead they use the actual compression of the piston to ignite the fuel. To start a diesel engine a glow-plug is used, once the engine has started the compression causes the ignition. As a results of this diesel engine blocks are heavier to take the force of the ignition
A 1990 Ford 7.3L diesel engine works by using a very high compression ratio to ignite a mixture of air a diesel. Unlike gasoline engines, it requires no spark to actually ignite the fuel.
Because one has a petrol engine and the other has a diesel engine. Petrol/gasoline does not ignite the same way as diesel. It also does not have the lubrication qualities that diesel has. Gas in a diesel engine will damage the fuel system if the diesel very quickly.
It won't run, that's for sure. Diesel is ignited by compression pressure, not by spark. And the compression in a gasoline engine is not sufficient to ignite the diesel.
The diesel engine doesn't have any spark plugs, and uses heat generated during compression to ignite the fuel. The diesel however, is an internal combustion engine.
