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 or the engine.

Claim (Index 52):
A fuel management system for a turbocharged spark ignition engine, comprising:\n a first fueling system that uses direction injection; and a second fueling system that uses port fuel injection, wherein the fuel management system is configured to provide fueling in a first torque range, the first torque range being a first range of torque values at which both the first fueling system and the second fueling system are operable throughout the first range of torque values, wherein the fuel management system is further configured to increase the fraction of fueling provided by the first fueling system as torque increases in at least a first part of the first torque range that begins at a lowest value of torque in the first torque range, wherein the fuel management system is further configured to provide fueling in a second torque range, the second torque range being a second range of torque values at which the second fueling system is operable throughout the second range of torque values and the first fueling system is not operable throughout the second range of torque values, wherein the fuel management system is further configured such that when the system provides fueling at a torque value that exceeds the second range of torque values, the turbocharged spark ignition engine is operated in the first torque range, wherein the fuel management system is further configured to use spark retard to reduce the fraction of fueling provided by the first fueling system, and wherein the fuel management system is further configured to use a stoichiometric air/fuel ratio in the first and second torque ranges.
