Nameplates on electrical motors show their power output, not the power input (the power delivered at the shaft, not the power consumed to drive the motor). This power output is ordinarily stated in watts or kilowatts. In the United States, the power output is stated in horsepower which, for this purpose, is defined as exactly 746 watts.
Engine power is the power that an engine can develop. It can be expressed in power units, most commonly kilowatt, metric horsepower (often abbreviated PS), or horsepower.In terms of internal combustion engines, the engine power usually describes the rated power, which is a power output that the engine can maintain over a long period of time according to a certain testing method, for example ...

The power measurement is often the average power used while running the benchmark, but other measures of power usage may be employed (e.g. peak power, idle power). For example, the early UNIVAC I computer performed approximately 0.015 operations per watt-second (performing 1,905 operations per second (OPS), while consuming 125 kW).
A typical turbocharged V8 diesel engine might have an engine power of 250 kW (340 hp) and a mass of 380 kg (840 lb), [1] giving it a power-to-weight ratio of 0.65 kW/kg (0.40 hp/lb). Examples of high power-to-weight ratios can often be found in turbines. This is because of their ability to operate at very high speeds.

The LK0 engine first used TBI (Throttle Body Injection) for fuel delivery and was rated at 85 hp (63 kW) at 5000 rpm and 107 lb⋅ft (145 N⋅m) at 2400 rpm from 1991 to 1994. [ 1 ] The L24 engine received MPFI (Multi-Port Fuel Injection) in 1995 which increased power output to 100 hp (75 kW) at 5000 rpm and 115 lb⋅ft (156 N⋅m) at 2400 rpm.
It was also fitted to the European market W123 wagon, the 300TD. This was the only turbocharged OM617 fitted to a European W123. Power originally was 121 PS (89 kW; 119 hp) @ 4350 rpm, torque 230 N⋅m (170 lb⋅ft) @ 2400 rpm. From October 1982 - 125 PS (92 kW; 123 hp) @ 4350 rpm, torque 250 N⋅m (184 lb⋅ft) @ 2400 rpm. [11]
