Port Timing Diagram Of 2 Stroke Diesel Engine. The port timing diagram gives an idea about when a phase of the two stroke cycle takes place. The diagram shown above illustrates the sequence of various events such as opening and closing of ports.
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. This representation is known as a port timing diagram. Port timing diagram for the two stroke engine piston upward movement when the engine piston moves upside which means it moves from the bottom dead centre bdc to top dead centre tdc the transfer port will be closed after 60 angle and the exhaust port will be closed after 70 from the bottom dead centre bdc.
Before the expansion stroke i e.
The diagram shown above illustrates the sequence of various events such as opening and closing of ports. Port timing diagram for the two stroke engine piston upward movement when the engine piston moves upside which means it moves from the bottom dead centre bdc to top dead centre tdc the transfer port will be closed after 60 angle and the exhaust port will be closed after 70 from the bottom dead centre bdc. First of all the exhaust port opens before the piston reaches bdc and the burnt gases start leaving the cylinder. Valve timing diagram for a two stroke diesel engine.
