Claim 0:
1. A system comprising:
a reciprocating piston engine configured to output torque to drive a load;
an engine speed sensor operatively coupled with the engine and configured to output an engine speed signal;
an electronic control system in communication with the engine and configured to receive the engine speed signal during operation of the engine, determine an engine acceleration based on the engine speed signal, determine whether the engine is operating in one of a steady state condition, a transient condition, and a high-load and high-speed condition, and determine a misfire of the engine based on: the engine speed signal if the engine is operating in the steady condition, the engine acceleration if the engine is operating in the transient condition, and an exhaust manifold pressure-based diagnostic if the engine is operating in the high-load and high-speed condition.
