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.

MOMENTUM DRIVEN FUEL INJECTION OF STEAM AND FUEL VAPOR FOR COMPRESSION IGNITION ENGINES

The present invention directly affects two primary limitations of diesel fuel: poor vaporization and ease of auto-ignition. Superheated fuel is injected within a cone of steam. As a result, fuel is fully vaporized and steam controls ignition by momentarily isolating fuel from air. In order to achieve high vapor velocities, the present invention uses momentum of circulating fuel and water to propel them through the injector. Momentum is preserved by transfer valves that transfer moving liquids between through paths and injection paths. Momentum is further preserved by an injector design that minimizes turbulence that would absorb energy and reduce injected velocity. The fuel and water may be superheated before injection to convert to steam and vapor upon the release of pressure when injected into the combustion chamber. The injector may also be used to achieve high injection velocity for liquid fuel injection without heating. 1.

An internally cooled internal combustion piston engine and method of operating a piston engine is provided, with the combination of liquid water injection, higher compression ratios than conventional engines, and leaner air fuel mixtures than conventional engines. The effective compression ratio of the engines herein is greater than 13:1. The engines may employ gasoline or natural gas and use spark ignition, or the engines may employ a diesel-type fuel and use compression ignition. The liquid water injection provides internal cooling, reducing or eliminating the heat rejection to the radiator, reduces engine knock, and reduces NOx emissions. The method of engine operation using internal cooling with liquid water injection, high compression ratio and lean air fuel mixture allow for more complete and efficient combustion and therefore better thermal efficiency as compared to conventional engines. 1. An internal combustion engine for use with a hydrocarbon fuel , the engine having at least one cylinder and a reciprocating piston therein , an intake manifold in fluid communication with at least one air intake valve , at least one exhaust valve in fluid communication with an exhaust manifold , and a fuel handling system with at least one fuel injector ,a water injector coupled to a water source for injecting liquid water into the port of the intake manifold;a programmed control device configured for controlling internal combustion engine operations, said programmed control device receiving one or more real-time temperature values in said engine and responsively adjusting an amount of water injected and an air to fuel ratio provided to the said at least one cylinder, said programmed control device controlling actuation of said liquid water injector to inject a predetermined quantity of liquid water into the a port of the intake manifold at a time from about 300° to about 180° before Top Dead Center (TDC) of said piston during a compression stroke, said liquid water ...

Augmented Compression Engine (ACE)

Номер: US20180363575A1
Автор: Niilo William Alexander Koponen
Принадлежит: Individual

Unlike similar internal combustion engines that vary the fuel-air mixture, the Augmented Compression Engine (ACE) first and foremost sets and maintains an optimal stoichiometric fuel to air ratio, relying upon various implementations of Boyle's law to attain ignition of the stoichiometric fuel-air mixture in the combustion chamber while varying quantities of the fuel-air mixture to adjust output power. An ACE uses fuel-air mixed prior to attainment of auto-ignition temperatures in the combustion chamber, compresses it and achieves ignition by an ignition source or use of compression heating the fuel-air to its auto-ignition temperature. Since different quantities of the fuel-air mix are needed for different loads (power outputs), to maintain reliable ignition the ACE uses one or more of: varying intake pressure; valve timing; recycled exhaust or other implementations of Boyle's law for adjusting compression such as, injected matter, modifying fuel or changing of combustion chamber volume.

FIELD: engines and pumps. SUBSTANCE: invention relates to the ICE exhaust gas recycling regulation (EGR). Claimed invention consists in adjustment of firing point and direct fuel injection with allowance for the engine operating performances and injected fuel composition for elimination of detonation. One or several engine parameters, for example the number of EGR, varying gas distribution phases, forced aspiration, throttle turn angle are coordinated with the direct injection for reduction of torque in transient modes. Proceeding from the EGR flow parameters, the engine load is varied whereat water is injected into the engine. Note here that said water is injected at different engine loads depending on current EGR conditions and directly-injected water amount is adjusted in compliance with EGR flow proceeding from the required level of dilution (depletion) of the mix in the cylinder. EFFECT: higher engine efficiency at transient modes. 10 cl, 14 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 573 074 C2 (51) МПК F02B 47/02 (2006.01) F02B 47/08 (2006.01) F02D 19/12 (2006.01) F02M 25/00 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ (21)(22) Заявка: ИЗОБРЕТЕНИЯ К ПАТЕНТУ 2011131928/06, 29.07.2011 (24) Дата начала отсчета срока действия патента: 29.07.2011 (72) Автор(ы): ЛЕОНЕ Томас Г.
