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.
Once two of the three reduced properties are found, the compressibility chart can be used. In a compressibility chart, reduced pressure is on the x-axis and Z is on the y-axis. When given the reduced pressure and temperature, find the given pressure on the x-axis. From there, move up on the chart until the given reduced temperature is found.
Brake force, also known as brake power, is a measure of force applied by the brakes of a vehicle in order to decelerate it. It is one of the main components in determining a vehicle's stopping distance.
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.
Mean Effective Pressure is defined as the average pressure that the gas exerts on the piston(s) through one complete operating cycle of the engine. This definition can be expressed in terms of the work per operating cycle as Work Per Operating Cycle = (Mean Effective Pressure) x (Swept Volume per Operating Cycle)
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 ...
The type of brake system in use only affects trucks and large mass vehicles, which cannot supply enough force to match the static frictional force. [1] [Note 2] The braking distance is one of two principal components of the total stopping distance. The other component is the reaction distance, which is the product of the speed and the ...
The brake balance or brake bias of a vehicle is the distribution of brake force at the front and rear tires, and may be given as the percentage distributed to the front brakes (e.g. 52%) [1] or as the ratio of front and rear percentages (e.g. 52/48). [2]
