| 20110168128 | System for Variable Blending Of Ethanol And Exhaust Water For Use As An Anti-Knock Agent - The present application describes systems for water retrieval from the engine exhaust. This collected water can be used both for removing ethanol from ethanol-gasoline blends, and for use as a knock suppressant. The water that is removed from the exhaust can be used as the only source of water or in combination with water that is externally supplied. The present application also describes new means for removal of water from the exhaust that can be employed for applications. In some embodiments, an auto-heat exchanger is employed to recover water from the engine exhaust. | 07-14-2011 |
| 20110120569 | Fuel Tank System For Gasoline And Flexible Ethanol Powered Vehicles Using On-Demand Direct Ethanol Injection Octane Boost - A fuel tank system for gasoline or flexible gasoline/ethanol powered vehicles that use independently controlled direct ethanol injection to provide a large on-demand octane boost is disclosed. The on-demand octane boost is used when needed to prevent knock. The ethanol can be in the form of 100% ethanol or E85 (a 85% ethanol, 15% gasoline mixture) and is stored in a second tank that is separate from the tank that which contains the primary fuel. The primary fuel can be gasoline, E85, ethanol or a mix of these fuels. The fuel tank system enables convenient, quick, flexible and minimal cost refueling of the separate fuel tank. A range of fueling options is available to provide the driver with the maximum freedom to choose fuels depending upon price and availability. Valves may be utilized to direct the flow in fuel to the various tanks. | 05-26-2011 |
| 20110114058 | HIGH EFFICIENCY NATURAL GAS/GASOLINE BI-FUEL ENGINES USING ON-DEMAND KNOCK CONTROL - A bi-fuel spark ignition engine is disclosed. The engine can operate on either gasoline, natural gas or a combination of the two. The amount of each fuel that is used by the engine is based on the engine's operating parameters, such as RPM and torque. In some embodiments, the operator can provide input, such as the availability of natural gas, which affects the operation of the engine. In some embodiments, an anti-knock agent is used to prevent knock at higher values of torque. | 05-19-2011 |
| 20110100323 | DIMETHYL ETHER (DME) ENHANCED GASOLINE ENGINE - An engine having DME pilot ignition is disclosed. DME Pilot ignition creates far more energy than a conventional spark plug, thus minimizes the possibility of misfire in the engine map. DME injection can be used in a number of ways. In one embodiment, DME injection replaces the conventional spark plug in an Otto cycle engine. In another embodiment, DME injection is used in addition to spark ignition to minimize the use of DME. In this embodiment, DME injection is only used during those portions of the engine map where misfire may occur, or during those times when a misfire sensor detects misfire. DME injection can also be used in conjunction with alcohol boosting in other embodiments. | 05-05-2011 |
| 20100198481 | Fuel Tank System for Direct Ethanol Injection Octane Boosted Gasoline Engine - 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. | 08-05-2010 |
| 20100147265 | SINGLE NOZZLE DIRECT INJECTION SYSTEM FOR RAPIDLY VARIABLE GASOLINE/ANTI-KNOCK AGENT MIXTURES - 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. | 06-17-2010 |
| 20100070155 | Gasoline Engine System Using Variable Direct Ethanol Injection and Engine Shutdown - 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. | 03-18-2010 |
| 20100070154 | Single Nozzle Injection of Gasoline and Anti-Knock Fuel - Fuel management system of operation of a spark ignition engine. The system includes a source of gasoline and a source of anti-knock fuel. A proportioning valve receives the gasoline and the anti-knock fuel to discharge a mixture having a controlled gasoline/anti-knock fuel ratio. A single high pressure pump receives the mixture and delivers the mixture to an injector. A fuel management control system controls the proportioning valve and the injector for injection of the mixture into a cylinder of the engine to control knock. A preferred anti-knock fuel is ethanol. | 03-18-2010 |
