One imperial horsepower lifts 550 pounds (250 kg) by 1 foot (30 cm) in 1 second. Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower.
Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight (or mass) of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by ...
Brake horsepower per cubic centimeter. Brake horsepower per cubic centimeter or (bhp/cc) is a figure of merit that is used to indicate the ' state of tune ' of an internal combustion engine. It is defined as the ratio of the engine's net power output to its displacement, the internal size. Power is measured at its rated speed and full throttle.
If Imperial units are used, and if torque is in pounds-force feet and rotational speed in revolutions per minute, the above equation gives power in foot pounds-force per minute. The horsepower form of the equation is then derived by applying the conversion factor 33,000 ft⋅lbf/min per horsepower:
Brake-specific fuel consumption. Brake-specific fuel consumption (BSFC) is a measure of the fuel efficiency of any prime mover that burns fuel and produces rotational, or shaft power. It is typically used for comparing the efficiency of internal combustion engines with a shaft output. It is the rate of fuel consumption divided by the power ...
Holden has built its own 3.2 L (3,195 cc) version of the High Feature engine in Australia produced between 2005 and 2010 with a bore and stroke of 89 mm × 85.6 mm (3.50 in × 3.37 in). Branded with the Alloytec name like the 3.6L version, this version produces 227 hp (169 kW; 230 PS) at 6600 rpm and 297 N⋅m (219 lb⋅ft) at 3200 rpm. It has ...
or 1.6/π = 0.51 times engine displacement in cc The limits between the horsepower denominations were drawn at either 0.49, 0.50, or 0.51 in different cantons. Thus, the eight horsepower category would cover cars of about 7.5–8.5 CV. In 1973 Berne switched to a taxation system based on vehicle weight, and a few other cantons followed.
The 2L is a 2.4 L (2,446 cc) 4-cylinder diesel engine. Bore and stroke are 92 mm × 92 mm (3.62 in × 3.62 in), with compression ratios of around 22.3:1 and a redline of 4800 rpm. Outputs range from 76 to 87 PS (56 to 64 kW; 75 to 86 hp) and torque of 15.8–16.8 kg⋅m (155–165 N⋅m; 114–122 lb⋅ft). Applications:
