2. Increase the cylinder diameter than the S/D

Increasing the cylinder diameter than the main purpose of the S/D is under the condition of invariable in keeping the average speed of piston Vm greatly reduce diesel engine rotating speed, to improve the efficiency of the propeller, so as to improve the overall efficiency of power plant.This is since the oil crisis of important measures to improve the economical efficiency of diesel engine power plant.So since the late 70 S, the increase of S/D is very fast, and gradually developed a long stroke and long stroke diesel engine at low speed diesel engine series.The increase of S/D, also make the economy of diesel engine itself.At present, the MAN B&W company's SMC - C series diesel engine S/D value has amounted to 4.0, and the W?Rtsil?Swiss company of SULZER RTA -t series diesel engine S/D value and even has reached 4.17.However, S/D that diesel engine's structure is complex, the cost increase, therefore there is a limit to the increase of S/D.
