Engine Combustion chamber A combustion chamber is the part of an engine in which fuel is burned. Internal combustion engine The combustion process increases the internal energy of a gas, which transl ...
Engine Compression ratio The compression ratio of an internal-combustion engine or external combustion engine is a value that represents the ratio of the volume of its combustion chamber from its lar ...
Engine Connecting rod In a reciprocating piston engine, the connecting rod or conrod connects the piston to the crank or crankshaft. Together with the crank, they form a simple mechanism that convert ...

Engine displacement explained One complete cycle of a four-cylinder, four-stroke engine. The volume displaced is marked in red. Engine displacement is the volume swept by all the pistons inside the c ...
Gudgeon wrist pin In internal combustion engines, the gudgeon pin (UK, wrist pin US) connects the piston to the connecting rod. In very early engine designs (including those driven by steam and also ...
Basics how a car engine works The car engine is an internal combustion engine, of which there are a number of various types including diesel engine, gasoline engine, rotary engine and engine two time ...
Car Piston types Car Piston assembly A piston is a component of reciprocating engines, reciprocating pumps, gas compressors and pneumatic cylinders, among other similar mechanisms. It is the moving c ...
Hypereutectic piston cosworth forged pistons A hypereutectic piston is an internal combustion engine piston cast using a hypereutectic alloy–that is, a metallic alloy which has a composition beyond t ...
Mean piston speed The mean piston speed is the average speed of the piston in a reciprocating engine. It is a function of stroke and RPM. There is a factor of 2 in the equation to account for one str ...
Piston rings Exlained car piston rings Most automotive pistons have three rings: The top two while also controlling oil are primarily for compression sealing (compression rings); the lower ring is fo ...
Engine Stroke ratio In a reciprocating piston engine, the stroke ratio, defined by either bore/stroke ratio or stroke/bore ratio, is a term to describe the ratio between cylinder bore diameter and pi ...
