Mean effective pressure (MEP) is defined by the location measurement and method of calculation, some commonly used MEPs are given here: Brake mean effective pressure (BMEP, ) - Mean effective pressure calculated from measured brake torque.
Prony brake dynamometers at a tractor contest in 1910 Schematic of a Prony brake Actual Prony Brake built for testing 5HP Steam Engine. 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 ...
A compression release brake (also known as a Jacobs brake or "jake brake"), is the type of brake most commonly confused with real engine braking; it is used mainly in large diesel trucks and works by opening the exhaust valves at the top of the compression stroke, so the large amount of energy stored in that compressed air is not returned to ...
Fairbanks-Morse learned that in shops that maintained multiple locomotive types, where the foreman was under pressure to repair as many locomotives as possible, repair of OP engines that required extensive disassembly was often delayed in favor of other types of locomotives that could be turned around more quickly.
British Railway Class 90 infobox showing brake force Brake force to weight ratio of the Class 67 is higher than some other locomotives. In the case of railways, it is important that staff are aware of the brake force of a train so sufficient brake power will be available to bring the train to a halt within the required distance from a given speed.
Maximum brake torque (MBT) is the use of optimal ignition timing to take advantage of an internal combustion engine's maximum power and efficiency. There is always an optimal spark timing for all operating conditions of an engine. MBT is ideal at wide-open throttle (WOT), but not desirable when the engine is at idle.
Harvard tied with Dartmouth and Columbia atop the conference at 5-2 this season, but scored head-to-head wins over both teams. Officially, the Ivy League recognized all three teams as co-champions.
English: This diagram shows the brake specific fuel consumption (BSFC) [g/kWh] of the smart forfour 3-cylinder Diesel engine with 1.5 liter displacement. The axes are horizontally rotational speed, n, in rpm and vertically mean effective pressure p e (bar)
