METHOD TO DETERMINE THE INJECTION PATTERN IN THE COMPRESSION STROKE OF THE COMBUSTION CYCLE OF THE CYLINDERS OF A DIRECT-INJECTION INTERNAL COMBUSTION ENGINE |
摘要 |
A method to determine the injection pattern in the compression stroke (COMP) of the combustion cycle of the cylinders (2) of a direct-injection internal combustion engine (1), comprising the steps of determining the initial quantity (QF init_comp ) of fuel and an objective quantity (QF obj_comp ) of fuel to be injected for each partial injection of a maximum number (N max_comp ) of partial injections; determining an effective quantity (QF eff_comp ) of fuel to be injected for each partial injection as a function of the respective initial quantity (QF init_comp ) of fuel and of the respective objective quantity (QF obj_comp ) of fuel; and determining an objective pattern of partial injections to be performed in the compression stroke (COMP) as a function of the value of the end of injection angle (EOI) and of the effective quantity (QF eff_comp ) of fuel to be injected for each partial injection of said maximum number (N max_comp ) of partial injections to be performed in the compression stroke (COMP). |
