One complete cycle of a four-cylinder, four-stroke engine. The volume displaced is marked in orange. Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. [1] It is commonly used as an expression of an engine's size, and by extension as an indicator of the ...
Horsepower. 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.
Engine efficiency of thermal engines is the relationship between the total energy contained in the fuel, and the amount of energy used to perform useful work. There are two classifications of thermal engines-. External combustion engines (steam piston, steam turbine, and the Stirling cycle engine). Each of these engines has thermal efficiency ...
Chrysler Intrepid with supercharged V8 and conversion to rear wheel drive. In car tuning culture, an engine swap is the process of removing a car 's original engine and replacing it with another. This may be a like-for-like replacement, or to install a non-factory specification engine.
Bore (engine) In a piston engine, the bore (or cylinder bore) is the diameter of each cylinder. Engine displacement is calculated based on bore, stroke length and the number of cylinders: [1] The stroke ratio, determined by dividing the bore by the stroke, traditionally indicated whether an engine was designed for power at high engine speeds ...
Power-to-weight (specific power) The power-to-weight ratio (specific power) is defined as the power generated by the engine (s) divided by the mass. In this context, the term "weight" can be considered a misnomer, as it colloquially refers to mass. In a zero-gravity (weightless) environment, the power-to-weight ratio would not be considered ...
Ford Zetec engine. The Ford Kent is an internal combustion engine from Ford of Europe. Originally developed in 1959 for the Ford Anglia, it is an in-line four-cylinder overhead-valve –type pushrod engine with a cast-iron cylinder head and block. The Kent family can be divided into three basic sub-families; the original pre-Crossflow Kent, the ...
The compression ratio is the ratio between the volume of the cylinder and combustion chamber in an internal combustion engine at their maximum and minimum values. A fundamental specification for such engines, it can be measured in two different ways. The simpler way is the static compression ratio: the ratio of the volume of the cylinder when ...
