Did you know?
WitrynaIn a 4-stroke cycle internal combustion engine equipped with a suction valve (13) and an exhaust valve (14) which are driven for opening and closing by a suction cam (17) and an exhaust cam (18), respectively, which are integral with a cam shaft (19), a decompressor cam (35) is fitted on the cam shaft (19) through a one-way clutch (34) … Witryna4. Exhaust Stroke – The exhaust valve is opened and the piston travels back up expelling the exhaust gases through the exhaust valve. At the top of this stroke the exhaust valve is closed. This process is then repeated. The above is the cycle of operation of one cylinder of a 4-stroke engine.
