Abstract:
Fuel management system for enhanced operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder. It is preferred that the direct injection occur after the inlet valve is closed. It is also preferred that stoichiometric operation with a three way catalyst be used to minimize emissions. In addition, it is also preferred that the anti-knock agents have a heat of vaporization per unit of combustion energy that is at least three times that of gasoline.

Claim (Index 36):
A fuel management system for a turbocharged spark ignition engine, comprising:\n a first fueling system configured to directly inject fuel into at least one cylinder of a turbocharged spark ignition engine as a liquid and increase knock suppression by evaporative cooling; and a second fueling system configured to inject fuel into a region outside of the at least one cylinder, wherein the fuel management system is configured to control fueling from each of the first and second fueling systems, wherein the first fueling system is configured to be used across a manifold pressure range of the spark ignition engine such that a fraction of total fuel introduced into the cylinder provided by the first fueling system increases with increasing manifold pressure, wherein the system is configured such that fuel provided at a maximum manifold pressure is provided by one of both the first and second fueling systems or the first fueling system without the second fueling system, wherein fueling from the first fueling system is initiated when torque of the engine exceeds a designated value, and wherein the engine is fueled with gasoline and ethanol.
