Tappet Clearance Inlet and Exhaust Pdf, Tool, Adjustment, How Rotocap works ? 3 0 obj <>>> Exhaust gasses are pushed out of exhaust ports situated just above the inlet ports until the air moves down. The top portion of the piston where valves are located is called Top dead center, and the opposite extreme down portion of the piston is called Bottom dead center. The fuel used to achieve the same level of power in CNG increases the in-cylinder temperatures by approximately 200oC, which shortens the life and reduces the strength of these metal parts, and accelerates the oxidation of engine oil. Speed: On the basis of speed, the types of engines are: (i). View Internal Combustion Engines.pdf from MECHANICAL GATE at Indian Institute of Technology, Guwahati. B) Loop scavenging :- In the loop scavenging, the incoming air moves over the crown of the piston and falls towards the head of the cylinder liner . common methods of distinguishing these engines include the combustion cycle, the valve location, the cooling system, the number and placement of the cylinders and the type of fuel used.
