Port Timing Diagram Of 2 Stroke Diesel Engine. A valve timing diagram is a graphical representation of the opening and closing of the intake and exhaust valve of the engine the opening and closing of the valves of the engine depend upon the movement of piston from tdc to bdc this relation between piston and valves is controlled by setting a graphical representation between these two which is known as valve timing diagram. Completion of the compression stroke the inlet port open 10 20 degree before the piston reaches the tdc which in turn starts the expansion stroke due to the combustion of air fuel petrol engine from the crankcase and air diesel engine entered from the inlet port which in turn pushes the piston towards bdc.
Port timing diagram for ci engine in the valve timing diagram as shown we see that the expansion of the charge after ignition starts as the piston moves from tdc towards bdc. Valve timing diagram for a two stroke diesel engine. Completion of the compression stroke the inlet port open 10 20 degree before the piston reaches the tdc which in turn starts the expansion stroke due to the combustion of air fuel petrol engine from the crankcase and air diesel engine entered from the inlet port which in turn pushes the piston towards bdc.
Since the one cycle is completed in one revolution of the crank the sequence of operation of the ports can be represented in a circle 360.
Here tdc top dead center bdc bottom dead center ipo inlet port open. This representation is known as a port timing diagram. Here tdc top dead center bdc bottom dead center ipo inlet port open.
