I spent most of the week working on adding fuel injection to the big natural gas engine, I was incorrect, this unit was 10,000 HP, the unit next to it was 7000 HP.
I saw the effects of retarded timing on heat generation. We needed to get the turbo hot enough to work, so we retarded the timing a few degrees after starting to generate heat to do that.
They added a pressure transmitter in each head that showed the pressure pulse created during ignition. We got to see the effects of that pulse by varying timing and boost.
This engine adds fuel in response to the governor, much like a diesel, then we had to control the turbo to make the air to fuel ratio correct. I always wondered how they did that in a diesel.
It was a very educational week. The engine is running, and are working on determining the correct data to model with.
