摘要

PURPOSE: A method for improving combustion efficiency of a diesel engine and a spiral annular alloy heat exchange conductor are provided to improve performance of the diesel engine and achieve a complete combustion by expanding fuel through radiating heat to the fuel by the spiral annular alloy heat exchange conductor. CONSTITUTION: A spiral annular alloy heat exchange conductor(4) is coated with low molecular ceramic. The spiral annular alloy heat exchange conductor(4) is mounted on a combustion port(3) formed at the top(2) of a piston(1). The spiral annular alloy heat exchange conductor(4) mounted on the combustion port(3) radiates heat towards mixing gas including air and fuel so that fuel is expanded, thereby achieving complete combustion.
