The wherewithal to allow diesel to burn when injected is always present
- the air within the cylinders is compressed to a point where the heat
from this will ignite the injected fuel. Petrol engines don't and can't
work like this.
They can and in some cases do. A few years ago it became a requirement
for a tank to run on any fuel from petrol to diesel, and the experiment
succeeded, the only problem was that as the fuel fractions go lighter so
the fuel economy got worse.
