COMBUSTION DEVICE FOR SWIRL CHAMBER TYPE DIESEL ENGINE

摘要

PROBLEM TO BE SOLVED: To improve a mixture state of fuel for combustion and air by a swirl chamber and a main nozzle. SOLUTION: A recessed groove 2b narrower than a main nozzle 3 through which unburnt gas is injected in a main combustion chamber 4 from a swirl chamber 2 is formed in a bottom part 2a of the swirl chamber 2 to receive a feed of fuel for combustion and air and mix them. The sectional shape of the main nozzle 3 forms a T-shape 3a and an auxiliary nozzle is formed in addition to the main nozzle 3.
