Embodiment Construction
[0011] In the embodiment shown in Figures 1 and 2: the diesel engine adopting premixed combustion in Figure 1 has no obvious difference in structure from the ordinary diesel engine. For example, the piston 1, connecting rod 2 and crankshaft 4 are the main moving parts, and the fixed parts And the major systems have not changed much, but a spark plug 6 is added to the cylinder head, and the intake cam 3 has also become relatively fat. The expansion ratio has been increased from the original 17 to 22. Figure 2 is the fuel supply, ignition and gas distribution phase diagram of the diesel engine shown in Figure 1. Obviously, the diesel engine with premixed combustion has obvious characteristics: the intake delay angle β is 80 degrees crank angle; the geometric fuel supply advance angle θ is 90 degree crank angle; spark plug ignition angle φ is 1 degree crank angle before top dead center. The intake advance angle α, exhaust advance angle γ and exhaust delay angle δ are the same as thos...
