travel of the pistons and piston rings. A connecting rod can rotate at both ends, so that the angle between the connecting rod and the piston can change...

"blow-by", are gases from the combustion chamber which have leaked past the piston rings. Early engines released these gases to the atmosphere simply by leaking...

hydraulic cylinder pistons. Static applications of O-rings may include fluid or gas sealing applications in which: (1) the O-ring is compressed resulting...

pin or piston pin US English) connects the piston to the connecting rod, and provides a bearing for the connecting rod to pivot upon as the piston moves...

piston rings are intended to seal the combustion chamber from the crankcase, it is normal for some combustion gases to escape around the piston rings...

of piston rings of leading engine builders. In 1925, Piston Ring bought the No-Leak-O Piston Ring Company, allowing the company to increase production...

by one or more piston rings. These are rings made of a hard metal, and are sprung into a circular groove in the piston head. The rings fit closely in...

atmospheric pressure acting against a partial vacuum that occurs as the piston travels downwards toward bottom dead centre during the intake stroke. Owing...

system used on many piston engines in aircraft and armored vehicles of the 1930s and 1940s. It used a cordite cartridge to move a piston, which cranked the...

often leads to large amounts of turbo lag, therefore it is mostly used on piston engine aircraft which usually do not need to rapidly raise and lower engine...

A hypereutectic piston is an internal combustion engine piston cast using a hypereutectic aluminum alloy with silicon content greater than the eutectic...

draco added two-stroke and four-stroke piston ring products to Federal-Mogul's portfolio of industrial piston rings. In December 2010 the company's Barcelona...

throttle is open, the air pressure on both sides of the blowoff valve's piston is equal, therefore the spring holds the valve closed. As the throttle closes...

sealing ability, cylinder, piston and piston ring life all depend on reliable contact between cylinder and piston/piston ring so any cylinder distortion...
