Describe the differences between an engine dynamometer and a chassis dynamometer.
What will be an ideal response?
An engine dynamometer is a machine that is bolted up to the crankshaft of the engine to measure its horsepower and torque. The engine dynamometer takes the place of and bolts to where the transmission would be. This means that the dynamometer will measure the power of the engine only and will not measure the power losses of the transmission and drivetrain.
A chassis dynamometer is used for similar purposes of testing and tuning an engine. The difference is that the engine is installed in the vehicle and the power is measured at the tires. The chassis dynamometer has a rolling drum that the tires drive on. The drum then rotates with resistance that is controlled by the operator.
