摘要: A flexible fuel compensation system including a method of hot soak fuel enrichment. The hot soak fuel enrichment method includes checking a plurality of enabling conditions. The method also increments of decrements a hot fuel enrichment multiplier depending on conditions of the vehicle. The hot fuel enrichment multiplier is then used to adjust the amount of fuel being sent to the fuel injectors.

摘要: A system and method of monitoring the purge flow in an evaporative emission control purge system of a motor vehicle. Signals indicative of engine speed, fuel control and automatic idle speed position are measured and used to determine whether the purge flow system is operating properly. With purge flow activated, the amount of purge flow is increased in accordance with a ramping rate and the measured signals are monitored to determine whether or not a change occurs in any one of the engine speed, fuel control and AIS position signals.

摘要: A method is provided for controlling knock on an internal combustion engine. The method includes the steps of determining a maximum value of knock and determining whether conditions are right for updating the maximum value of knock. The method also includes using an unmodified spark advance if conditions are not right for updating the maximum value of knock and modifying the spark advance if conditions are right for updating the maximum value of knock.
