A machined casting containing cylindrically bored holes for the pistons of a multi-cylinder reciprocating internal combustion engine.
A component of reciprocating engines, pumps and gas compressors. It is located in a cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod.
An open-ended ring that fits into a groove on the outer diameter of a piston in a reciprocating engine such as an internal combustion engine or steam engine.
The part of an engine which translates reciprocating linear piston motion into rotation.
A shaft to which a cam is fastened or of which a cam forms an integral part.
An electrical generator that uses permanent magnets to produce pulses of high voltage alternating current. At one time the magneto was used in the ignition system of most gasoline-powered internal combustion engines to provide power to the spark plugs.
An electrical device that fits into the cylinder head of some internal combustion engines and ignites compressed fuels such as aerosol gasoline, ethanol, and liquefied petroleum gas by means of an electric spark.
Consists of a platform containing part of the combustion chamber , and the location of the poppet valves and spark plugs. In a flathead engine, the mechanical parts of the valve train are all contained within the block, and the head is essentially a flat plate of metal bolted to the top of the cylinder bank with a head gasket in between.
A gasket that sits between the engine block and cylinder head in an internal combustion engine.
The cover which contains the rear bearing.
Gasket that prevents oil from leaking from the oil pan when assembled.
A valve consisting of a hole, usually round or oval, and a tapered plug, usually a disk shape on the end of a shaft also called a valve stem.That allows air fuel mixture to enter the cylinder bore.
A valve consisting of a hole, usually round or oval, and a tapered plug, usually a disk shape on the end of a shaft also called a valve stem.That releases the spent fyel fumes.
Springs that keep the valves closed when not being pushed up.
A projection which imparts a linear motion to some other component within an assembly. Properly speaking, a tappet is only that part of a rocker arm which makes contact with an intake or exhaust valve stem above the cylinder head of an internal combustion engine.
A mechanical device with a significant moment of inertia used as a storage device for rotational energy. Flywheels resist changes in their rotational speed.
Pin that holds the flywheel in the correct timing for delivering a spark.
A gear type, driven by the crankshaft or camshaft, or a rotor type.
Connects the piston to the crank or crankshaft.
A device that blends air and fuel for an internal combustion engine.
A safe container for flammable liquids and typically part of an engine system in which the fuel is stored and propelled or released into an engine.
A device for reducing the amount of noise emitted by a machine.
A cord in which you pull to deliver a manual rotation to start the engine.
An item that covers or protects some other object.
