Multi Cylinder Engine Car, To transfer the energy resulting from this expansion into useful work, a construction such as shown in is used.
multi cylinder engine car force exerted piston is transmitted connecting rod to the crankshaft that is made to revolves turning through half revolution piston moves downward. Attached to the crankshaft is a flywheel, which stores up energy The momentum of the flywheel carries the piston through the balance of its motion until it receives another power pulse. multi cylinder engine this way the reciprocating motion of the piston is transformed into a rotary motion at the crankshaft. From that point on, the power is trans mitted back to the rear wheels as will be explained in Unit Seven on the power train. For the continuous operation of the engine, this senes of events must be repeated over and over agan in regular order.
these events that are repeated make up the cycle of the engine the number of strokes of the piston required to complete the cycle varies with the type of engine In the type universally used in modeern American passenger cars, the cycle is extended through four strokes of the piston or two revolutions of the crankshaft this is called a four-stroke-cycle or a fourcycle engine. multi cylinder engine cycle were completed in two strokes of the piston or one revolution of the crankshaft, as is the case in some engines not currently used in American passenger cars, but employed in some diesel-powered trucks and buses. the engine would be called two stroke cycle suction Stroke.
multi engine car this stroke the piston is moved downward by the crankshaft, which is revolved either by the momentum of the flywheel or by the power generated by the electric starting motor. engine car movement of the piston increases the size of the combustion space, thereby reducing the pressure in it. multi cylinder engine car the higher pressure of the inside atmosphere forces fresh mixture into the combustion space through the open inlet valve
