Abstract
A starting fuel supply system for an internal combustion engine, comprising an electronic injection system, and processing means which, prior to stroke identification of the engine, cause fuel to be supplied to more than one injector, including the injector relative to the cylinder first reaching the ignition point subsequent to such identification, and which has already completed the induction stroke, thus enabling substantially total intake of the fuel injected into the cylinder.
Claims9
A starting fuel supply system for an internal combustion engine (101), comprising an electronic injection system, characterized by the fact that said system comprises processing means (102) which, prior to stroke identification in said engine (101), cause fuel to be supplied to more than one injector (116), including the injector relative to that cylinder first reaching the ignition point subsequent to such identification, and which has already completed the induction stroke, thus enabling a substantially total intake of the fuel injected into said cylinder;
- further characterized by the fact that said processing means (102) comprise means (142, 142') for calculating the amount of fuel supplied to said injectors (116), prior to identification, by means of reduced parameters and in a simplified manner as compared with the calculation performed for subsequent sequential, timed supply of individual injectors (116);
- and further characterized by the fact that said parameters comprise only the cooling water temperature and the air pressure inside the induction manifold (107) of said engine (101).
A starting fuel supply system for an internal combustion engine (101), comprising an electronic injection system, characterized by the fact that said system comprises processing means (102) which, prior to stroke identification in said engine (101), cause fuel to be supplied to more than one injector (116), including the injector relative to that cylinder first reaching the ignition point subsequent to such identification, and which has already completed the induction stroke, thus enabling a substantially total intake of the fuel injected into said cylinder;
- further characterized by the fact that said processing means comprise means (140, 141, 148, 149, 145, 151) for detecting signals (S, C) from first sensor means (103) adapted to detect given angles of a drive shaft (125), and from second sensor means (105) adapted to detect given angles of a distributor (126) shaft, said detecting means (140, 141, 148, 145, 151, 149) controlling, as a function of said incoming signals (S, C), fuel supply to a given combination of said injectors (116).
