The frequency of a crankshaft imbalance in an 8-cylinder engine at 600 RPM can be calculated by considering the engine's firing order and the number of power strokes. In a typical 8-cylinder engine, there are 4 power strokes per revolution (since two cylinders fire every crankshaft revolution). Therefore, at 600 RPM, the frequency of the imbalance would be 600 RPM / 60 seconds = 10 Hz, and since there are 4 power strokes per revolution, the imbalance frequency would be 10 Hz x 4 = 40 Hz.

The main parts of the reciprocating engine are the crankshaft and pistons. They reciprocate in the cylinder block.

The location of the crankshaft position sensor depends on which engine the car has. If it is the 2.5L 4 cylinder engine the crankshaft position sensor is behind the ignition module. If it is the 2.8L V6 engine the crankshaft position sensor is on the side of the engine nearest the firewall and just above the pan rail in about the center of the block.

In a twin-cylinder four-stroke engine, the crankshaft completes one full rotation for every two strokes of the pistons. Since the crankshaft is turning at 1000 RPM, the camshaft, which is typically driven by the crankshaft at half that speed, will turn at 500 RPM. Thus, the camshaft in this engine will be rotating at 500 RPM.
In a four-cylinder engine, a power stroke occurs once every two revolutions of the crankshaft. Since there are four cylinders, each cylinder completes a power stroke at intervals of 180 degrees of crankshaft rotation. Therefore, a power stroke is delivered every 90 degrees of crankshaft rotation when considering the firing order of the cylinders.
