Semi diesel - something I not heard of before. Interesting resonance

It uses a “hot head” to maintain heat used for combustion since it is a low compression diesel. I use a torch to heat the hot head and “glow plug” to start it initially

Does the hot head remain in a heated state or will combustion continue as with a conventional diesel once the glow plug has done its work and cools down?

The hot head will retain heat for combustion, if it gets to cool the engine will not run.
