Question

Explain the meaning of "the power of engine is 60 watt".​

Answer 1

Answer:

Engine power is the power that an engine can put out. It can be expressed in power units, most commonly kilowatt, pferdestärke, 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 ISO 1585. In general though, an internal combustion engine has a power take-off shaft (the crankshaft), therefore, the rule for shaft power applies to internal combustion engines: Engine power is the product of the engine torque and the crankshaft's angular velocity.
