  • Method and system for operating automotive internal combustion engine during start-up
    Patent number: 5249560
    Abstract: A system and method for operating an automotive internal combustion engine during start-up includes steps of sampling at least one operating parameter of the engine, comparing the sampled parameter to a predetermined range for such parameter, and in the event that the sampled parameter falls outside of the predetermined range, operating some of the engine's cylinders according to a base fuel schedule, while reducing the time-averaged amount of fuel provided to the remaining cylinders. Once the sampled parameter falls within the predetermined range, all cylinders of the engine will be operated according to the same fuel schedule.
