CYLINDER HEADS AND VALVES. 1.DEFINITION Cylinder head is a casting that covers the top of a cylinder.
Engine Compression. We have already seen how internal combustion engines develop compression Basically the piston is slightly smaller in diameter than.
PISTONS, RINGS, AND CONNECTING RODS
Exhaust valve Exhaust valves open inwards into the cylinder, so that the gas pressure in the cylinder will ensure positive closure and help in dislodging.
LESSON FIVE PISTONS. 1.DEFINITION A cylindrical metal component which reciprocates in the cylinder under gas pressure. It is connected to the piston.
Compression Is an adiabatic process. This means heat is derived from the process. As we squeeze the air fuel mixture it gets hot. Normal compression ratio.
Piston The piston comprises of two pieces, the crown and skirt. The crown is subjected to high temperatures in the combustion space and is liable to be.
CYLINDER LINERS LESSON FOUR. 1.LINER DEFINITION A removable component, cylindrical in shape, inserted into the engine block. It can be replaced when worn.
