It's True!

The desire for ultimate control can be obtained with Autodesk Maya. This amazing program has so many connection points, utility nodes and warp deformers that if you can think it, you can animate it. For engine animations, you need a wide variety of different processes (pistons, valves, actuators, spark; etc.) to happen during every full rotation of the crankshaft, repeatedly. Independently keyframing all these processes can surely be done, but the timeline becomes quite congested, not to mention the ability to accelerate and de-accelerate all those things would become painstakingly cumbersome.

There is a better way!

Harnessing the driving force of the crankshaft's (timeline set) rotational key frames, I have been able to take advantage of the many features and functions Maya has to offer to directly connect the crankshafts movement to dynamically control every other moving part on the engine. Thus, making the programs ability to increase or decrease the engine speed as easy as moving one rotational keyframe!
