According to my son the car nut, since diesel engines can run biodiesel which can have the consistency of light vegetable oil, the compression ratio is going to be very similar.

Adding pure oxygen is going to reduce the ratio by about 30-40% (normal air has 21% oxygen). The problem is going to be that the "boom" is going to be very energetic because of the pure oxygen. You are going to need something like an automobile engine to contain it, otherwise you will shrapnel.

You will have to mist the oil and inject the oxygen somehow prior to the final compression, usually in an engine this takes place just before top dead center on the compression stroke of the engine. At top dead center is when ignition takes place, driving the cylinder down for the power stroke.
