What Do Power, Torque, and Horsepower Mean?

[DelKai]

Engine power refers to the work done by an object per unit of time, indicating how much energy a car engine can unleash within a certain period. Horsepower is the unit of power—the greater the car's power, the higher the horsepower, and the faster the speed. Torque represents the engine's strength, while maximum torque indicates the maximum force the engine can produce. Power is directly proportional to torque and engine speed. Engines with higher torque produce greater power, and those with higher RPMs also generate more power. High-RPM engines perform more work cycles per unit of time, while high-torque engines deliver greater force per cycle. To increase engine power, simply raise the torque or RPM. Many automakers use turbocharging technology to boost engine power. Turbocharging primarily enhances engine torque by increasing air intake without enlarging engine displacement. With more air intake, correspondingly increasing fuel injection raises engine power. Turbocharged engines feature a turbocharger, which consists of two parts: a compressor turbine and an exhaust turbine. The compressor turbine is connected to the intake manifold, while the exhaust turbine links to the exhaust manifold—both turbines are coaxially joined.
