The part of an engine that houses the valve train, exhaust and intake ports, combustion chamber, distributor, spark plugs, etc. It sits on top of the engine block.
That part of the engine that covers the cylinders and pistons.
a detachable plate that covers the closed end of a cylinder chamber in a reciprocating engine or pump
a cast aluminum alloy or cast iron engine component fastened to the end of the cylinder block farthest from the crankshaft
a casting generally made out of iron or aluminum that holds the valves, valve springs and retainers and one or two camshafts Click for larger view, The crankcase and the valve train of the engine
a casting generally made out of iron or aluminum that holds the valves, valve springs and retainers and one or two camshafts (overhead cam engines only)
a long aluminum casting, full of holes
a metal part within the engine that covers the cylinders
A casting forming part of the combustion chamber; housing for the valves, sparkplugs and injectors and carries part of the cooling system.
The casting at the top of the engine, which contains the valves and associated operating components. amper - See shock absorber.
The top of the cylinder block that contains the spark plugs and valves. It seals the cylinder and forms the top of the combustion chamber.
Made of aluminum, it is bolted to the top of each side of the engine block. Cylinder heads hold the valves and spark plugs. Passages through the heads make up the intake and exhaust ports.
The aluminum or iron casting that has the combustion chambers, the intake and exhaust ports of the engine.
The detachable portion of the engine, usually fastened to the top of the cylinder block and containing all or most of the combustion chambers. On overhead valve engines, it contains the valves and their operating parts. On overhead cam engines, it contains the camshaft as well.
The part of the above the engine block that contains the combustion chambers and the valves. The spark plugs screw into the top or side of the cylinder head. On most cars, a valve cover, camshaft cover, or a rocker-arm cover is located on top of the cylinder head.
That portion of a motor that caps the open (generally top) ends of the cylinders. In modern engine designs, the cylinder head(s) generally house the spark plugs and the intake/exhaust valves.(empty)(empty)(empty)(empty)
The closed end, usually detachable, of a cylinder in an internal-combustion engine.
In an internal combustion engine, the cylinder head sits atop the cylinders and consists of a platform containing part of the combustion chamber and the location of the 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; this simplicity leads to ease of manufacture and repair, and accounts for the flathead engine's early success in production automobiles and continued success in small engines, such as lawnmowers. This design, however, requires the incoming air to flow through a convoluted path, which limits the ability of the engine to perform at higher rpm, leading to the adoption of the overhead valve head design.
