Abstract

A control method for the combustion system comprises: a fuel injector conducts first primary spray and second primary spray at intervals, and the fuel injector injects fuel to a first arc ridge during the first primary spray; and the fuel injector sprays fuel to a second arc ridge during the second primary spray. By adopting a combustion chamber having two arc ridges and respectively injecting fuel to the two arc ridges by means of the fuel injector, it can be ensured that the amount of fuel shared by each arc ridge is reduced, gathering the fuel at a single arc ridge can be avoided, and it is beneficial to exert the improvement effect of the arc ridge on a wall impact jet flow velocity field at the tail end of a fuel beam, such that the fuel and gas distribution in a cylinder is facilitated.
