KIVA Simulation

October 11, 2005, 00:40

Dear All:

I am trying to simulate a 4-stroke engine motion with KIVA 3V R2. Fuel injections are supposed to be at 330 CAD and 372 CAD. While all fuel evaporated, there is no combustion through the cycle. Could anyone provide some advice on the issue? Thanks in advance.

If you use ca1inj to specify the start of injection t1inj has to be set to -1.0. If the injected fuell mass (tspmas) is too low, you do not notice combustion. Temperature has to be high enough. I know that it's all obvious, but happend to me.
