 Is it possible to make motor engines which can run on both petrol and diesel at the same time?

It is not only possible, but it was done over 40 years ago.

This is the LDT 465 engine:

It was used in these, the M35 2 1/2 ton truck:

It uses a fuel density compensator in the injection pump to adjust the amount of fuel delivered based on how viscous the fuel is. It also uses a swirl chamber in the top of the piston to help with combustion.

The engine could run on diesel, jet fuel, kerosene, heating oil, or gasoline.

Gasoline wasn’t advised for long use unless a little oil was mixed into it to help lubricate the injection pump, but it would run on it.

This engine was designed in the 1960s, and was in use into the early 2000s. With more modern materials, it would likely be easier to use gasoline without the lubrication problems.
