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.

The Prony brake is a simple device invented by Gaspard de Prony in 1821 to measure the torque produced by an engine. The term "brake horsepower" is one measurement of power derived from this method of measuring ...
Power-to-weight ratio (PWR, also called specific power, or power-to-mass ratio) is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power-to-weight ratio is a measurement of actual performance of any engine or power source.
The International Loadstar is a series of trucks that were produced by International Harvester from 1962 to 1978. [1] The first product line of the company developed specifically as a medium-duty truck, the Loadstar was slotted between C-Line pickup trucks and the heavy-duty R-series.
The Super Great had driver's airbag and wheel parking brake equipped in 2000. The Super Great's cab was heavily facelifted, and the UD Trucks based AdBlue Urea Selective catalytic reduction system was equipped in 2007 on the facelift version, also used in the Nissan Diesel Quon. In April 2017, the Super Great received another facelift.
To calculate the actual efficiency of an engine requires the energy density of the fuel being used. Different fuels have different energy densities defined by the fuel's heating value. The lower heating value (LHV) is used for internal-combustion-engine-efficiency calculations because the heat at temperatures below 150 °C (300 °F) cannot be ...
The L10 displaced 10.0 litres (610.2 cu in), and was available in either a vertical form, for upright use in trucks and buses, or horizontal form, for underfloor use in buses and trains. The L10 was Cummins's first competitive offering in the British bus market, as their earlier production had been too large and heavy. [ 1 ]
The Isuzu 6H is a family of inline six-cylinder diesel engines installed in Isuzu medium-duty trucks, and also installed in GM medium-duty trucks as the Duramax LG4. It is mated to the Allison 2500, 3000, and 3500 series transmissions.
