Embodiment Construction
[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and the embodiments given by the inventor.
[0015] In-cylinder direct injection circumferential stratified combustion system includes: a combustion chamber 2 with the bottom surface of the cylinder head as the upper top and the upper surface of the ω-shaped piston as the lower bottom; a spark plug 3 and a multi-hole fuel injector arranged on the cylinder head 4; an intake valve 5 and an exhaust valve 6 arranged on the cylinder head; a spiral intake passage 7 communicates with the combustion chamber 2 through the intake valve 5 at its lower end, so that the incoming air is formed in the combustion chamber Vortex; an exhaust passage 8 communicates with the combustion chamber 2 through the exhaust valve 6 at its lower end, so as to discharge the combustion gas in the combustion chamber.
[0016] The working process of the in-cylinder direct injection circumferenti...
