horsepower
- Amount of power needed to lift a 550-lb. object at a rate of one foot in one second
- Horsepower is expressed as the torque in lb.-ft. times the number of revolutions per minute divided by the constant 5252:
- Gross horsepower is obtained by a dynamometer test of an engine equipped only with the built-in accessories essential to its operation, such as fuel pump, oil pump, coolant pump and built-in emissions-control equipment
- Net horsepower is obtained by a dynamometer test of a complete engine equipped with all the accessories necessary to perform its intended functions unaided, including the air-intake system, exhaust system, cooling system, generator, starter and emissions-control equipment
- Torque is what gets a vehicle moving, and horsepower is the force required to keep a vehicle moving once torque has started the vehicle moving from a standstill.
