Abstract: PROBLEM TO BE SOLVED: To improve fuel consumption by promoting the reduction of heat loss in an internal combustion engine in which a fuel and a non-combustion fluid (e.g., water) are injected into a combustion chamber of the internal combustion engine.SOLUTION: A combustion system for an internal combustion engine has a fuel injection valve 20 injecting a fuel directly into a combustion chamber 10a of the internal combustion engine and a water injection valve 30 (non-combustion fluid injection valve) injecting water (non-combustion fluid) into the combustion chamber 10a. The water is injected to collide with a fuel spray that is injected from the fuel injection valve 20. Therefore, a completely penetrating force of the fuel spray is decreased and the fuel spray hardly reaches a cylinder wall surface 10b. Thus, combustion can be performed at a position away from the cylinder wall surface 10b, and thereby, the amount of the combustion heat transferred to the cylinder wall surface 10b is reduced to decrease the heat loss of the combustion.

Abstract: PROBLEM TO BE SOLVED: To provide an exhaust emission control device for maintaining a catalyst at the active temperature over a long period, by reducing conduction of heat to the internal combustion engine side from the catalyst. SOLUTION: When a gasoline engine 11 stops operation, an exhaust passage 21 is closed by an upstream side orifice part 30 and a downstream side orifice part 40. A storage space 26 for storing a three-way catalyst 24 by the upstream side orifice part 30 and the downstream side orifice part 40, is reduced in pressure by a pressure reducing pat 50. By storing the three-way catalyst 24 in the storage space 26, exhaust gas remaining around the three-way catalyst 24 does not flow out to any of the atmospheric side and the engine body 14 side. The movement of the heat with the exhaust heat as a heating medium is reduced by reducing pressure in the storage space 26. Thus, the temperature of the three-way catalyst 24 hardly drops. As a result, the movement of the heat by the exhaust gas is reduced, and a temperature drop in the three-way catalyst 24 is reduced. COPYRIGHT: (C)2009,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide an exhaust emission control device for reducing a specific substance discharged together with exhaust gas, by raising the temperature of a catalyst in a short period of time, when starting an internal combustion engine, without causing a pressure loss and upsizing of a physical constitution.
SOLUTION: An orifice part 40 arranged in an exhaust passage 41 controls the cross-sectional area of the exhaust passage 41 and a flow of the exhaust gas in the exhaust passage 41 by adjusting opening of a first valve member 44 and a second valve member 47. When the temperature of a three-way catalyst 32 is low, the orifice part 40 introduces the flow of the exhaust gas to a part on the outer peripheral side of the three-way catalyst 32. Thus, when the temperature of the three-way catalyst 32 is low, the exhaust gas is introduced to a part of the three-way catalyst 32, and the temperature of the three-way catalyst 32 rises in a short period after starting an engine body 13. The orifice part 40 expands the cross-sectional area of the exhaust passage 41 as the temperature of the three-way catalyst 32 rises, and fully opens the exhaust passage 41 when the temperature of the three-way catalyst 32 reaches the active temperature. Thus, the exhaust gas is introduced to the whole of the three-way catalyst 32, and the pressure loss is reduced.
