Title: Fuel injection control device for internal combustion engine
Inventor: MORI KATSUYUKI
IPC: F02D41/06
Filed: 1999-11-29
Abstract: PROBLEM TO BE SOLVED: To dissolve a problem that a feed amount of auxiliary fuel is differed every cylinder since auxiliary fuel is injected in an intake pipe regardless of a cycle of each cylinder only for a specified time after ON of a starter though it is known that an auxiliary fuel injection device is provided in an intake pipe to improve startability of an internal combustion engine. SOLUTION: By dividing an injection timing for auxiliary fuel, each division injection timing is synchronized with the suction stroke of each cylinder. Further, by correcting an injection amount of each division injection timing according to a suction rate, i.e., a distribution rate of auxiliary fuel differed classified by each cylinder, auxiliary fuel to all of cylinders is evenly distributed and startability is improved by improving a combustion state. 411-414 are taken as pulses at which main fuel is injected in a cylinder and 401-404 are taken as pulses corrected for injection of auxiliary fuel in an intake pipe.
