SUCTION STROKE: In this Stroke the inlet valve opens and proportionate fuel-air mixture is sucked in the engine cylinder. Therefore, the cycle consists of 7200 of crankshaft rotation. Each stroke consists of 1800 of crankshaft rotation.
Since ignition in these engines is due to a spark, therefore they are also called spark ignition engines. In four stroke cycle engine, cycle is completed in two revolutions of crank shaft or four strokes of the piston. Question: Explain the working of four stroke petrol engine with neat sketch.Įxplain with diagram how the Four stroke petrol engine works.įOUR STROKE PETROL ENGINE refers to its use in petrol engines, gas engines, light, oil engine and heavy oil engines in which the mixture of air fuel are drawn in the engine cylinder. Question: Represent Brayton cycle on PV and TS diagram. If the heat added during constant volume process isĪ) Maximum temperature in the cycle b) Air standard efficiency
