Abstract

DECREASING THE COMPRESSION RATIO WILL RESULT IN ENGINE POWER FAILURE AND INCOMPLETE COMBUSTION AND IF THE ENGINE'S VOLUMETRIC EFFICIENCY REACHES A LEVEL THAT COMPENSATES FOR THE LOW ENGINE DENSITY, THE COMPRESSION RATIO CAN BE LOWERED. IN CURRENT ENGINES, SUPERCHARGING OR TURBOCHARGING ARE USED IN ORDER TO INCREASE THE VOLUMETRIC EFFICIENCY. BY REVERSING THIS PROCEDURE, EMITTING CAN SPEED UP. EMITTING AT A HIGH SPEED AND PRESSURE FROM THE COMBUSTION CHAMBER REDUCES THE OPENING TIME OF THE SMOKE VALVE AND PROVIDES MORE TIME FOR OPEN AIR VENTS. WE PROPOSED THAT THE OPENING OF THE SMOKE VALVE BE OCCURRED FROM 45O BEFORE THE REACHING THE PISTON BDC TO 60O AFTER THE PISTON BDC. AT THIS TIME, THE SMOKE IS DISCHARGED WITH HIGH PRESSURE AND HIGH SPEED BY THE SUPERCHARGER. IN THIS PAPER WE STUDY ON REDUCING THE COMPRESSION RATIO OF THE DIESEL ENGINE AND INCREASING THE VOLUMETRIC EFFICIENCY WITHOUT INCREASING THE INLET AIR PRESSURE.
