Abstract: Fuel management system for efficient operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder of the engine. A fuel management microprocessor system controls injection of the anti-knock agent so as to control knock and minimize that amount of the anti-knock agent that is used in a drive cycle. It is preferred that the anti-knock agent is ethanol. The use of ethanol can be further minimized by injection in a non-uniform manner within a cylinder. The ethanol injection suppresses knock so that higher compression ratio and/or engine downsizing from increased turbocharging or supercharging can be used to increase the efficiency of the engine.

Abstract: Air quantity of ISC is roughly controlled on the basis of the lift amount of an intake valve, whose air flow rate control range is wide. The adjustment of the air quantity beyond the range of the rough control is achieved by the control based on a phase of the intake valve. As a result, a required flow rate can be achieved with high accuracy. If only the intake-valve lift amount whose air flow rate control range is wide is used to achieve the required air quantity of ISC, a fuel control system requires both a high degree of accuracy of an intake-valve lift amount sensor and a high degree of accuracy of an intake-valve lift amount control mechanism itself, which leads to high system costs. The air quantity of ISC is roughly controlled on the basis of the intake-valve lift amount whose air flow rate control range is wide (the air quantity is controlled based on an air flow rate corresponding to each integral multiple of the air flow rate control minimum resolution).

Abstract: A unitary high pressure seal provides a fluid seal against multiple surfaces, at least one of which is static and one of which is dynamically loaded. The seal includes a seal body and separated load and sealing lands. The load land interfaces with the static surface, e.g., a valve assembly barrel, to seal the body to that surface, whereas the sealing land dynamically provides a seal against a variably positioned surface, e.g., a valve head surface. In this manner, when the valve is closed, the load land is not affected by the dynamic loads on the sealing land, and leakage at the static surface is thus minimized.

Especially, in a case that the fuel pressure sensor is provided to each of a plurality of injectors, it is desirable to obtain the variation waveform based on the output of the fuel pressure sensor provided to a cylinder in which no fuel injection is currently performed.

A vacuum pump in the vent passage may assist the flow of the purged fuel vapor.
