In traditional units, it measures fuel consumption in pounds per hour divided by the brake horsepower, lb/(hp⋅h); in SI units, this corresponds to the inverse of the units of specific energy, kg/J = s 2 /m 2. It may also be thought of as power-specific fuel consumption, for this reason. BSFC allows the fuel efficiency of different engines to ...
BMW 502 The M502/1 engine in a 1957 BMW 502. The BMW 501, which began production in 1952, was the first car produced by BMW after World War II.It was powered by the 2.0 L (122 cu in) BMW M337 straight-six engine [2]: 46 [3] (based on the pre-war BMW M78 engine), which struggled with the 1,285 kg (2,833 lb) mass of the 501.
The Speed Eight engine had a high specific output for a normally aspirated engine at the time, with 83.3 bhp/L for the 4.2L, [2] 93.3 bhp/L for the 4.5L, and 97.7 bhp/L for the Red Rose-specification 4.5L engine. Another notable aspect is the weight of the engine, which is 121 kg (267 lb) dry.
A typical turbocharged V8 diesel engine might have an engine power of 250 kW (340 hp) and a mass of 380 kg (840 lb), [1] giving it a power-to-weight ratio of 0.65 kW/kg (0.40 hp/lb). Examples of high power-to-weight ratios can often be found in turbines.
265 lb (120 kg) excluding headers, clutch, ECU, spark box or filters The Honda HR-09E and Honda HR-10EG are 3.4-liter, naturally-aspirated , V8 racing engines , developed and produced by Honda for use in Formula Nippon and Super GT , starting in 2009.
Porsche 9R6 RS Spyder 3.4 L V8 engine. The 4.6-liter engine was derived directly from the engine of the successful RS Spyder. It outputted 447 kW (608 hp) at 8,700 rpm. Porsche engineers created direct fuel injection with centrally located solenoid injectors – an especially efficient and low-emission combustion process.
1.5 L (1,493 cc or 91.1 cu in) I3, with a single overhead camshaft, four valves-per-cylinder, and common-rail direct fuel injection. This engine was designed in 1998 with the related 4-cylinder variant R 420 SOHC. In 1999, VM granted Hyundai the license to manufacture both engines.
Pound per hour is a mass flow unit based on the international avoirdupois pound, which is used in both the British imperial and, being a former colony of Britain, the United States customary systems of measurement. It is abbreviated as PPH, or more conventionally as lb/h. Fuel flow for engines may be expressed using this unit.
