The extreme position of the bottom of the cylinder is called bottom dead centre bdc in the case of horizontal engine this is known as outer dead centre odc. To draw the valve timing diagram of 4 stroke diesel engine. 4 stroke diesel engine tachometer frictional dynamometer stop watch weights and hangers sand fuel etc.
Inlet exhaust valves open and close as well as the firing of fuel in a 4 stroke marine diesel engine it is generally expressed in terms of angular positions of the crankshaft.
This relation between the valve opening timings to the piston moves from the top dead centre tdc to the bottom dead centre bdc can be represented on a circle. Valve timing diagram for 4 stroke engine petrol and diesel as we all know in 4 stroke engine the cycle completes in 4 strokes that are suction compression expansion and exhaust the relation between the valves inlet and outlet and piston movement from tdc to bdc is represented by the graph known as valve timing diagram. In the case of 2 stroke marine diesel engines. Performance test and preparation of heat balance sheet on 4 stroke single cylinder diesel engine.
