apm Posted June 4, 2017 Share Posted June 4, 2017 Diesels require sudden high cylinder pressures concentrated to generate enough heat to self ignite Never said to run the rotary as a diesel cycle, its a spark ignition engine. And you can spark ignite JetA, Its how the turbines operate. The PT6's run just fine with compressor ratio of 6.3 in early models and 10.8 in later and igniters to light the kero.

So its still a possibility to achieve. Link to comment Share on other sites More sharing options...
facthunter Posted June 5, 2017 Share Posted June 5, 2017 The wankel has a long shallow combustion chamber. One reason it will never have high efficiency. Too much area for volume . Diesel won't vapourise unless you heat it or inject it at high pressure. It also has a very LOW octane rating and incline the engine to knock. A small amount of it in avgas will kill the engine quickly and destructively. It's happened many times when erroneously added where the engine cowl says "TURBO" and the fueler takes it as turbine.
