Our main products are Cylinder Head, Engine Piston, Engine Cylinder Head. The cylinder head The 2.0l FSI engine with 4-valve technology has an aluminium cylinder head. Take a V-8 engine, for example. The valve shown is from a slow speed MAN-B&W two stroke engine but a lot of modern engines have valves working on similar principles and design. Two stroke crosshead engines have a single exhaust valve mounted in the centre of the cylinder head. The trick is to get the valve body located first so the rotor turns smoothly and then tighten up all the other screws. an intake (intake of fuel-air mixture) and an exhaust valve (exhaust gases). Opening the intake valve before TDC can result in exhaust gasses flowing into the intake manifold instead of leaving the cylinder through the exhaust valve. Valve Breakages – Fracture at lower cotter groove. To allow a gas to be contained within the gas cylinder shell a valve is fitted into the open end, at the neck.
