Does petrol work in a diesel engine?

Answer 1

The self ignition temp of petrol is much higher than diesel hence only compression in diesel engine cannot initiate the combustion .thus petrol cannot be used in diesel engine.

There was an episode of "Amazing Race" a couple of years ago where the contestants jumped into the cars they were given to drive to the next destination. They were all diesel. They had to stop on the way there and fill up the tanks. It was night and about half the contestants did not notice that the cars were diesel and they pumped gasoline into the tanks. The cars did in fact get down the road a ways until they finally stopped. The most enterprising of the contestants was an older gentleman who crawled underneath his car, disconnected the fuel line, drained the tank, reconnected it, and refilled it with diesel.

No a diesel will not run on gasoline.
