Improved internal combustion engine power systems (e.g., those used to generate mechanical or electrical power in vehicular applications) that utilize a reformed alcohol fuel comprising a hydrogen-containing gas mixture, and more particularly, the efficient operation of such engines and power systems are disclosed. Modes of operating the engine power systems that provide faster startup and lower cost and emissions are provided. In various preferred embodiments, the internal combustion engine power systems include dilution of the intake fluid mixture introduced into the combustion chamber or cylinder of the engine using recirculated exhaust gas and/or excess combustion air as the diluent, use of blends of ethanol reformate and unreformed ethanol as fuel and aftertreatment of the exhaust gas discharged from the cylinder using a lean NOtrap.

Reformed ethanol engines

A method to start an internal combustion engine having a variable event valvetrain is provided. The method includes increasing the speed of said internal combustion engine during a start from a stopped position after a request to start said internal combustion engine. The method may further include increasing an intake valve lift amount, of at least a cylinder during said start while said internal combustion engine speed is increasing. The method may further include only enabling fuel flow to said cylinder when said intake valve lift amount reaches a predetermined level.

Method for controlling a variable event valvetrain

Boosted engine operation and spark timing of an engine may be adjusted with alcohol content of the fuel in a direct injection engine. Further, various adjustments may be performed in numerous related systems to account for increased maximum engine torque, such as traction control, transmission shifting, etc.

Direct injection alcohol engine with boost and spark control

A system and method for delivering EGR to an internal combustion engine is presented. The system can reduce system cost and lower system complexity.

System and method for improving exhaust gas recirculation for a turbocharged engine

Methods and systems for separating fuel and supplying the separated fuel to an engine are disclosed. In one example, alcohol is separated from a blend of alcohol and gasoline. The methods and systems may improve fuel separator operation by adjusting separator operation in response to engine operating conditions.

Ethanol separation using air from turbo compressor

A method of controlling fuel supplied to an engine is provided. In one example, a cylinder includes port and direct fuel injection. The method includes supplying a second fuel type from a second tank to the direct injector and supplying a first fuel type from a first tank to the port injector; and responsive to mis-fueling, supplying the first fuel type from the first tank to the direct injector. In response to receiving an indication of a mis-fuel, the direct fuel injector may be supplied with the second type of fuel from the second fuel storage tank. By supplying at least some fuel to the direct injector from a different source, fuel may be supplied to the DI fuel injector at various conditions to cool the DI fuel injector. In this way, overheating of the DI fuel injector may be reduced.

Approach for reducing overheating of direct injection fuel injectors

A method of controlling fuel supplied to an engine of a vehicle is provided. The method may improve engine starting during cold operating conditions. In one example, the type of fuel injected to the engine is changed in response to operating conditions.

Approach for enhancing emissions control device warmup in a direct injection engine system

A system for an engine, comprising of a cylinder of the engine; a first injector configured to inject a first substance to said cylinder; a second injector configured to inject a second substance to said cylinder; and a controller configured to commence combustion in the engine by injecting fuel into said cylinder, where said fuel is injected by only one of said first and second injectors during said start and/or warm-up.

Warm up strategy for ethanol direct injection plus gasoline port fuel injection

A method of controlling fuel supplied to an engine is provided. The engine includes at least one cylinder having a port injection fuel injector being supplied with fuel from at least one of a first fuel storage tank and a second fuel storage tank and a direct injection fuel injector being selectively supplied with fuel from one of the first fuel storage tank and the second fuel storage tank. The method includes at a first condition, supplying at least some of a second type of fuel from the second fuel storage tank to the direct injection fuel injector and supplying at least some of a first type of fuel from the first fuel storage tank to the port injection fuel injector, and at a second condition, supplying at least some of the first type of fuel from the first fuel storage tank to the direct injection fuel injector.

A system for an engine, comprising of a cylinder located in the engine, a first injector configured to inject gasoline fuel into said cylinder, and a second injector configured to inject a fluid into said cylinder, said fluid containing at least some water.

Engine with water and/or ethanol direct injection plus gas port fuel injectors

A method of controlling fuel supplied to an engine of a vehicle is provided. The vehicle includes a first fuel storage tank to store a first type of fuel, a second fuel storage tank to store a second type of fuel, and an emissions control device. The engine includes at least one cylinder having a direct injection fuel injector being selectively supplied with the first type of fuel from the first fuel storage tank and the second type of fuel from the second fuel storage tank. The method includes supplying the first type of fuel from the first fuel storage tank to the direct injection fuel injector in response an engine start condition of the vehicle, and supplying the second type of fuel from the second fuel storage tank to the direct injection fuel injector, in response to an increase in engine output exceeding a threshold increase or a temperature of the emissions control device exceeding a threshold temperature.
