In order to investigate the effect of the timing of swirl creation upon the combustion process of a Diesel engine, various amounts of fuel were injected from two sets of fuel-injection equipments into the main and auxiliary chambers respectively at a different period. A swirl was created in the main chamber by a violent outflow of gas from the auxiliary chamber. Swirl creation prior to fuel injection into a main chamber brings a little improvement on the combustion state, but is accompanied by an unfavorably rapid rise of high pressure. Swirl creation after ignition is more effective to shorten the after-burning of fuel, as ascertained by the high-speed photography. When fuel is injected into an auxiliary chamber after TDC, the noiseless and smokeless combustion with fairly low maximum pressure is materialized without the increase in fuel consumption.
