Abstract: A vapor solenoid valve is connected so as to lead to a canister. A vapor line connecting port and a purge line connecting port are connected to a vapor line and a purge line, respectively. When switched on and in an open position, the vapor solenoid valve connects a canister connecting port, the vapor line connecting port and the purge connecting port to each other, and thus allows a fuel evaporative gas to flow out of and into a canister or allows air to flow from an air filter. When switched off and in a CLOSED position, the vapor solenoid valve closes the canister connecting port and connects only the vapor line connecting port and the purge line connecting port to each other, and thus inhibits the fuel evaporative gas from flowing out of and into the canister.

Abstract: An oxygen sensor system for a vehicle includes a pump control module, a correction module, and a fuel control module. While fueling of an engine is cut off, the pump control module selectively turns ON an air pump that pumps ambient air into an exhaust system of the vehicle upstream of a universal exhaust gas oxygen (UEGO) sensor and a catalyst. The correction module receives an output of the UEGO sensor, selectively determines a correction for the output of the UEGO sensor when the air pump is ON and the fuel is cut off, and adjusts the output of the UEGO sensor based on the correction to produce a corrected output. The fuel control module, during fueling of the engine, selectively controls the fueling based on the corrected output.

Abstract: A system for a vehicle includes a rate of change module, a period estimation module, a deceleration fuel cutoff (DFCO) module, and an injection control module. The rate of change module determines a rate of change of an engine speed. While an engine is being fueled, the period estimation module determines an estimated period of a next DFCO event based on the rate of change of the engine speed. The DFCO control module selectively generates a DFCO signal based on the estimated period. The injection control module cuts off fuel to the engine when the DFCO signal is generated.

An adsorption material is disposed within the housing. In a desorption mode, fuel vapor desorbed by the adsorption material is desorbed from the adsorption material as air flows into the housing via the third port and flows out of the second port. A plurality of heaters are disposed within the housing and are arranged along a path of flow of air from the third port to the second port in the adsorption mode. A controller controls the heaters such that the heaters start to heat the adsorption material in order of the air flow direction from the third port to the second port. The controller preferably also terminates heating of the adsorption material in the same manner.

The non-conductive reinforced fibers have a fiber direction which is substantially the same as the perpendicular direction.

Abstract: A method adjusts fuel injection based on a fuel make-up, such as a fuel ethanol content. The fuel make-up may be learned during transient conditions by correlating transient fueling effects caused by the different evaporation rates of higher and lower ethanol content to measured exhaust air-fuel ratio. In this way, an ethanol content independent of combustion stoichiometry can be obtained, even during transients, that is less sensitive to part variation and sensor drift.
