Claim 20:
21. A computer apparatus for performing diagnostics on a reciprocating piston engine, the computer apparatus comprising:
an interface configured to be communicatively coupled with the engine and to receive information indicating an engine speed, and
a processor configured to execute instructions stored in a non-transitory computer-readable memory medium to:
determine an engine acceleration in response to the information indicating the engine speed,
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
detect a misfire of the engine in response to: 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.
