Publication number: 20100198481Abstract: Fuel tank system for a direct ethanol injection octane boosted gasoline engine. The system includes a gasoline engine and a main fuel tank that contains a mix of gasoline and gasoline E85. A smaller secondary tank is provided to contain ethanol or E85. An injector directly injects in a separately controlled fashion ethanol or E85 into a cylinder of the engine to boost octane. A control module controls the relative amounts of gasoline and ethanol used and structure is provided for fueling the main and secondary fuel tanks.Type: ApplicationFiled: April 14, 2010Publication date: August 5, 2010Applicant: ETHANOL BOOSTING SYSTEMS LLCInventors: Leslie Bromberg, Paul N.

Patent number: 7762243Abstract: Engine management system for operation of a direct injection spark ignition gasoline engine. The system includes a gasoline engine, a source of gasoline and a source of an anti-knock agent. Gasoline and anti-knock agent are introduced into a proportioning valve that delivers a selected mixture of gasoline/anti-knock agent to a high pressure pump. At least one injector receives the selected mixture from the high pressure pump and delivers the mixture into a cylinder of the engine. The engine management system provides a rapidly variable mixture of directly injected anti-knock agent and gasoline which prevents knock as the engine torque increases.Type: GrantFiled: January 28, 2010Date of Patent: July 27, 2010Assignee: Ethanol Boosting Systems, LLCInventors: Leslie Bromberg, Paul Blumberg, Daniel R. Cohn, John Heywood

Patent number: 7740004Abstract: 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.Type: GrantFiled: August 17, 2007Date of Patent: June 22, 2010Assignee: Massachusetts Institute of TechnologyInventors: Daniel R. Cohn, Leslie Bromberg, John Heywood

Publication number: 20100121559Abstract: A fuel management system for using water for on-board vehicular separation of ethanol from ethanol-gasoline blends is described. Water or a water-alcohol mixture from a secondary tank is mixed with the ethanol-gasoline blend resulting in separation of the ethanol. By using on-board vehicular separation, the consumption of the externally supplied liquid from a secondary tank can be decreased to less than 1% of the gasoline consumption. This allows for long refilling periods for the externally supplied fluid. In another embodiment, a water-based fluid is directly injected into the cylinders of a spark ignition engine to eliminate knocking without causing misfire. In a further embodiment, an alcohol-based fluid is also used in those circumstances where injection of the water-based fluid may cause misfire.Type: ApplicationFiled: November 2, 2009Publication date: May 13, 2010Inventors: Leslie Bromberg, Daniel R.

Publication number: 20100070155Abstract: Fuel management system for operation of a spark ignition gasoline engine. The system includes a gasoline engine powering the vehicle and a source of gasoline for introduction into the engine. A source of an anti-knock fuel such as ethanol is provided. An injector directly injects the anti-knock fuel into a cylinder of the engine and the control system shuts down the engine by stopping gasoline and anti-knock agent flow into the engine during vehicle deceleration and idling and restarts the engine upon driver demand. Direct ethanol injection and engine shutdown results in efficiencies similar to those of full hybrid vehicles.Type: ApplicationFiled: November 9, 2009Publication date: March 18, 2010Applicant: ETHANOL BOOSTING SYSTEMS LLCInventors: Leslie Bromberg, Paul N.
