Short answer is that it wouldn't work, and it would ruin the engine. If
you don't understand the difference between diesels and gas engines, you
wouldn't understand the long answer.

Steve, thanks for the insult.

I do understand the difference between a diesel cycle and a spark ignited
engine. While my thermodynamics classes were decades ago we did study the
matter.


Gas does not have the lubricating qualities of diesel, and can ruin
injectors and pumps that are not designed to handle it.

Even some diesel fuels don't have the lubricity of other diesel fuels.
IIRC the newer low sulphur fuels have lower lubricity than the older
fuels and can lead to shortened lives in some older injection pumps.
There are multifuel engines, such as what are installed on some
military trucks, made by Continental, that would run on just about
anything -- but you need to do some mechanic work to switch over. It
is not as simple as pouring a new tank of whatever is your latest
greasy find.

I am sure that gasoline would also self-ignite quite well during a diesel
cycle. Maybe the compression ratio would have to be reduced thereby also
reducing stress on the engine parts.

Try me with your longer answer and see if I can comprehend.
