[0014] figure 1 A schematic diagram of a swirl chamber combustion system utilizing an umbrella spray with a start-up hole is shown. The figure mainly shows the main combustion chamber 3, the swirl chamber 6 and the insert 4, and the insert 4 is provided with a main channel 4a and a starting hole 4b connecting the main combustion chamber 3 and the swirl chamber 6. In addition, there is also an umbrella-shaped spray nozzle 7 for spraying umbrella-shaped spray 7a into the swirl chamber 6. The nozzle centerline 7b of the umbrella-shaped spray nozzle 7 overlaps with the channel centerline 4c of the main channel 4a.
[0015] The function of the start-up hole 4b designed on the insert is that during cold start-up, the airflow velocity in the vortex chamber 6 is low, and part of the sprayed oil particles can directly enter the main combustion chamber 3 with relatively high air temperature from the start-up hole 4b. Ignition and combustion in the main combustion chamber 3, or re-enter...
