The term "engine power" refers to the total output or capacity of an engine, typically measured in horsepower (hp) or kilowatts (kW). It is a measure of how much mechanical force an engine can produce and is determined by factors such as its size, design, and efficiency. Engine power is important because it determines the performance capabilities of vehicles, machines, and equipment that use engines to generate motion. The higher the engine power, the greater the ability for acceleration, speed, and torque, making it an essential specification when comparing different types of engines or selecting one for a specific application.
