very unlikely frm the diesel bro cause diesl is compression
engine
not combustion engine. more likey should be the electricals n
engine oil.
diesel has a much higher burning point than petrol.
We call it flash point, disesel being one of the earliest stage of
crude oil process, it does not catch fire as much as petrol which
is a refined product of disesel with vapourising addictive to
enchance is performance in term of clean, better flowing and quick
combustion. Petrol is further refined into many other product and
grade, and the highest is aircraft fuel, burnt very fast.
In ship and shipyard, we use diesel to wash our dirty hand
and clean engine parts.
