摘要： A fuel control for an engine using a liquid fuel mixture of two fuels such as gasoline and alcohol has a fuel composition sensor and stores a fuel composition value derived from the sensor near the end of one period of engine operation. That value is used in place of the actual fuel composition sensor output for a predetermined time at the start of the next period of engine operation. The predetermined time is at least long enough for the fuel movement caused by the fuel pump to remix separated fuel in the vicinity of the fuel composition sensor and may conveniently be the period of time from the initiation of fuel pump activity until the time that fuel from the tank would be expected to at least reach the sensor.

摘要： A fuel control for a vehicle engine using a liquid mixture of two fuels includes a fuel vapor canister open to the fuel tank and canister purge apparatus effective to allow fuel vapors to be drawn from the canister to the engine at a controlled purge rate during engine operation. The canister purge apparatus is responsive to a fuel composition sensor to vary the purge rate as a function of the fuel composition. If the two fuels are gasoline and methanol, the canister purge rate is varied, in a predetermined range of fuel temperature, so as to provide a higher purge rate for mixtures of gasoline and methanol, in at least some proportions, than for either gasoline or methanol alone. The canister purge rate may further be varied in response to fuel temperature.

摘要： A vehicle engine fuel control adapted for multi-fuel operation uses a fuel injection system in which fuel in a liquid mixture of first and second combustible fuels is injected in pulses of controlled duration at a predetermined pressure to achieve a predetermined air/fuel ratio. The first and second combustible fuels have different viscosities, so that the viscosity of the mixture changes with its composition as well as fuel temperature. The duration of the portion of the pulse duration in which fuel flows is varied in response to fuel composition and fuel temperature so as to compensate for the variation in viscosity of the fuel mixture and thus deliver the required amount of fuel with each pulse.

摘要： A fuel control for an engine using a liquid mixture of two fuels such as gasoline and methanol and derives a fuel control parameter from the output of a fuel composition sensor in a first mode of engine operation and locks the value of the fuel control parameter at the end of the first mode of engine operation for use throughout a second mode of engine operation including closed loop control in response to an air/fuel ratio sensor, as long as the fuel composition does not change more than a predetermined amount during the second mode. The stable operation of the fuel control in the second mode is thus protected from instabilities introduced by small fluctuations in the fuel composition signal. In an engine with adaptive learning control, the adaptive learning control mode is reserved for particularly stable modes of engine operation including closed loop stoichiometric control and thus serves well as the second mode of engine operation.

摘要： A fuel control for an engine using a liquid mixture of two fuels, such as gasoline and methanol, having different volumetric heat contents is responsive to a fuel compostion sensor to update a stored engine fuel control parameter. When a significant change in fuel composition is sensed, the stored engine fuel control parameter is not updated for a fuel transition time duration to allow the unchanged fuel still in the conduit between the sensor and engine to be used with the unchanged stored engine fuel control parameter.

摘要： A thermal management system includes an enable module, a status module and a temperature control module. The enable module enables generation of ammonia for use in selective catalytic reduction (SCR) catalysts of an exhaust system during a passive SCR mode. The status module determines whether the exhaust system is operating in a passive SCR mode and generates a passive SCR active signal. The passive SCR mode includes operating an engine with rich air/fuel ratios. The temperature control module activates electrical heating of an oxidation catalyst based on the passive SCR active signal and a temperature of the oxidation catalyst.
