piston engine, the cylinder head sits above the cylinders, forming the roof of the combustion chamber. In sidevalve engines the head is a simple plate...

Cylinder-head-sector (CHS) is an early method for giving addresses to each physical block of data on a hard disk drive. It is a 3D-coordinate system made...

Cylinder head porting refers to the process of modifying the intake and exhaust ports of an internal combustion engine to improve their air flow. Cylinder...

crossflow cylinder head is a cylinder head that features the intake and exhaust ports on opposite sides. The gases can be thought to flow across the head. This...

a head gasket provides the seal between the engine block and cylinder head(s). Its purpose is to seal the combustion gases within the cylinders and...

non-crossflow cylinder head is one that locates the intake and exhaust ports on the same side of the engine. The gases can be thought to enter the cylinder head and...

auto manufacturers have incorporated similar cylinder head designs. The engine block and cylinder heads were cast and manufactured at Indianapolis Foundry...

The Subaru six-cylinder engines are a series of flat-6 engines manufactured by Subaru, made in three distinct generations. The ER27, derived from the Subaru...

A Heron cylinder head, or simply Heron head, is a design for the combustion chambers of the cylinder head on an internal combustion piston engine, named...

narrow V angle which allows a single cylinder block and cylinder head. These engines use a single cylinder head so are technically a straight engine with...

A Cylinder Head Temperature gauge (CHT) measures the cylinder head temperature of an engine. Commonly used on air-cooled engines, the head temperature...

A multi-valve or multivalve engine is one where each cylinder has more than two valves (an intake, and an exhaust). A multi-valve engine has better breathing...

The Jaguar XK is an inline 6-cylinder dual overhead camshaft (DOHC) engine produced by Jaguar Cars between 1949 and 1992. Introduced as a 3.4-litre, it...

aluminium alloy cylinder heads and cast iron cylinder blocks. The AGZ had 10 valves in total with 2 unequal sized valves per cylinder and chain driven...

pushrod engine, is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with flathead (or "sidevalve")...

(OHC) engine is a piston engine in which the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve...

engines. The intake manifold on this series was cast integrally with the cylinder head (this design was also used by Chevrolet with some of their later third-generation...

aluminium cylinder blocks with three or four cylinders in-line. Cylinder heads have two overhead camshafts, driven by chain, and four valves per cylinder. Fuel...

engines developed within this family have aluminium cylinder block and head, 4 valves per cylinder, double overhead camshaft layouts, and MIVEC continuous...

internal-combustion piston engine some of whose major components (such as cylinder head, cylinder block, or crankcase) are formed, usually by casting, as a single...

deliver power and torque consistent with those of larger-displacement (cylinder volume) naturally aspirated engines, while achieving up to 20% better fuel...

1JZ-GE; however, the design of the cylinder head is unique. The ‘D4’ FSE employs a relatively narrow angle cylinder head with swirl control valves that serve...

In a reciprocating engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic...
