摘要: An evaporative emissions (EVAP) control system for a vehicle includes a purge pump configured to pump fuel vapor trapped in a vapor canister to an engine of the vehicle via a vapor line when engine vacuum is less than an appropriate level for delivering fuel vapor to the engine, the fuel vapor resulting from evaporation of a liquid fuel stored in a fuel tank of the engine. The EVAP control system includes a hydrocarbon (HC) sensor disposed in the vapor line and configured to measure an amount of HC in the fuel vapor pumped by the purge pump to the engine via the vapor line. The EVAP control system also includes a controller configured to, based on the measured amount of MC, control at least one of the purge pump and a purge valve to deliver a desired amount of fuel vapor to the engine.

摘要: An evaporative emissions (EVAP) control system for a vehicle includes a purge pump configured to pump fuel vapor to an engine of the vehicle via a vapor line and a purge valve. The system includes a hydrocarbon (HC) sensor disposed in the vapor line and configured to measure an amount of HC in the fuel vapor pumped by the purge pump to the engine via the vapor line. A controller is configured to: detect an imminent cold start of the engine and, in response to the detecting, perform the cold start of the engine by controlling at least one of the purge pump and the purge valve, based on the measured amount of HC, to deliver a desired amount of fuel vapor to the engine, which decreases HC emissions by the engine.

摘要: A direct injection fuel supply system, in one exemplary implementation, includes a lift fuel pump, a positive displacement pump, at least one fuel injector and an accumulator assembly. The lift pump is adapted to be in fluid communication with a supply of fuel and the positive displacement pump is in fluid communication with and downstream of the lift pump. The at least one injector is in fluid communication with an outlet of the positive displacement pump via a high pressure fuel line. The accumulator assembly includes an accumulator and a valve, where the valve is in direct fluid communication with the high pressure fuel line and the injector. The valve is selectively controlled to at least one of an open state providing fluid communication between the accumulator and the high pressure fuel line and a closed state blocking fluid communication between the accumulator and the high pressure fuel line.

摘要: A direct injection (DI) fuel supply system includes an accumulator valve coupled to a high pressure fuel line at a position between an accumulator and a fuel rail. A controller of the DI fuel supply system is configured to control the accumulator valve to maintain the pressurized fuel housed in the fuel rail at a desired pressure and to control the accumulator valve proximate a fuel injection event by a fuel injector such that the accumulator supplies the fuel rail with approximately the portion of the pressurized fuel injected by the fuel injector during the fuel injection event. This positioning of the accumulator valve between the DI positive displacement fuel pump and the fuel rail together with active control thereof also insulates the fuel rail and the fuel injector from fuel pressure pulsations generated by the DI positive displacement fuel pump.

摘要: A fuel supply system with an accumulator that allows for the accumulation of fuel at a pressure greater than the nominal operating pressure of the fuel supply system. The accumulation of fuel allows for less frequent fuel pump operation and therefore a reduction in overall fuel consumption of an engine.
