Title:
METHOD OF CONTROLLING FUEL INJECTION APPARATUS FOR INTERNAL COMBUSTION ENGINES
Document Type and Number:
WIPO Patent Application WO/1996/037695
Kind Code:
A1
Abstract:
A method of controlling a fuel injection apparatus for internal combustion engines, and is capable of preventing the breakage of a component exposed to high-temperature heat, such as an exhaust manifold. According to the present invention, a first temperature and a second temperature higher than the first temperature are set in advance, and a temperature of an exhaust gas from an internal combustion engine (1) is detected. The number of times at which the temperature of the exhaust gas has exceeded the first set temperature and the time during which the temperature of the exhaust gas has exceeded the second set temperature are totaled respectively, and, either when the total number of times exceeds a predetermined level or when the total time exceeds a predetermined level, at least one of the following corrective actions are taken; giving an alarm, reducing a fuel injection rate and changing the injection timing.
