Petrol needs a spark plug for ignition so it would probably not work if injected in diesel engine,which isn't provided with one, as diesel self ignites.

Answer / prasuna

Diesel needs to be broken into a smaller state (tiny
drops). In a petrol engine this doesn't happen. So the fuel
cant burn. A diesel is timed for the slow ignition of the
diesel fuel (that's where the sound comes from.) If you
where to put petrol in a diesel it would ignite the sec.
the injector fires it into the cylinder and the piston
wouldn't be at top dead center. So when the petrol burned
(exploded) it would fight the piston coming up.

knocking sound increases

Answer / mitesh mevada

there is no chance to start ignition if we inject diesel in
petrol engine and petrol in diesel engine.because diesel
engine have compressed air in the ignition instead of it
petrol engine have dry air thats what petrol engine have
spark plug n diesel engine does not have spark plug.so.

Answer / ram pratap yadav

if we inject diesel in petrol engine and petrol in diesel
engine.it is impossible to start both engine due to some
reason.
dieselengine have compressed air in the ignition instead of
itpetrol engine have dry air thats what petrol engine have
spark plug n diesel engine does not have spark plug

Answer / gopikrishnan

when petrol is injected in diesel engine.
1.starting trouble occurs
2.ignition delay occurs
3.piston and piston rings wears sequently

Answer / umesh parmar

Working principle and Design of both the engines are
different.
So the Engine cannot run.
Case 1 : In case of injecting Petrol in diesel engine,
Due to commpression and low igntion point of Petrol it will
ignite before it is desired(TDC=Top Dead Centre) point.
Case 2 : In case of injecting Deisel in Petrol engine,
diesel will not burn effectively.

Answer / moosa alias mohasin

*when petrol is injected in diesel engine.
*PRE COMBUSTION WILL OCCURE .because ignition point of petrol is less than diesel (compression ratio of diesel engine is higher than petrol engine)

*when diesel is injected in petrol engine
*engine will work .but alot of smoke will produced .This will deposite carbon in engine parts like spark plug, piston head.......
