When you consider the early test engines Rudolph Diesel tried, for example feeding coal dust in with the intake air and other fuels, they were all called Diesels even though they did not have any way to inject the fuel. The final product would not necessarily remove his name from the other methods. His research was to find an auto "self" ignition engine that was practical. The model Diesel fits that description perfectly, so in my book the model Diesel is as deserving of the name "true Diesel" as any other.
