Combustion system for internal combustion engine

Номер: US20120298071A1
Автор: Munehisa Horibe, Satoru Sasaki, Takamasa Yokota, Yoshiaki Nishijima
Принадлежит: Denso Corp

A combustion system of an internal combustion engine has a fuel injector injecting a fuel directly into a combustion chamber and a water injector injecting a water (non-combustible fluid) into the combustion chamber. The water collides with a fuel spray which the fuel injector injects. A penetrating force of the fuel spray is decreased and the fuel spray hardly reaches a cylinder wall surface. The injected fuel is combusted at a position away from the cylinder wall surface, so that the combustion heat transferred to the cylinder wall surface is reduced and the heat loss of the combustion can be decreased.

Fuel management system for variable ethanol octane enhancement of gasoline engines

Номер: US20120312284A1
Автор: Daniel R. Cohn, John B. Heywood, Leslie Bromberg
Принадлежит: Massachusetts Institute of Technology

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.

Control device and control method for internal combustion engine with supercharger

Номер: US20150013637A1
Автор: Masaharu Kassai
Принадлежит: Nissan Motor Co Ltd

An internal combustion engine ( 1 ) is provided with a supercharger ( 12 ) and a cylinder direct injection fuel injector ( 10 ). When the engine shifts in a low-speed supercharging region at a state where the wall temperature of a cylinder bore ( 3 ) is low, liquid fuel adheres to a wall surface of the cylinder bore ( 3 ) so that lubricating oil is diluted with the liquid fuel and released into a combustion chamber ( 4 ). As a result, there occurs abnormal combustion. In the present invention, the fuel injection amount is increased at the time when the engine shifts in a predetermined low-speed supercharging region. The lower the wall temperature of the cylinder bore, the larger the rate of increase of the fuel injection amount. This makes it possible to suppress the temperature of air-fuel mixture in the vicinity of compression top dead center and prevent the occurrence of abnormal combustion.

FUEL MANAGEMENT SYSTEM FOR VARIABLE ETHANOL OCTANE ENHANCEMENT OF GASOLINE ENGINES

Номер: US20190048811A1

Принадлежит:

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. 133-.
