Abstract
A water injection device for injecting water into the combustion chambers of an engine is disclosed. Water particles are injected through a system other than the fuel injection nozzle, and the water is injected through a suction system, but as to the injection of the water particles, the injection rate and injection time are optimally controlled in accordance with the internal situations of the combustion chambers.
Claims14
A water injection device for an engine, comprising:
- a water injector configured to be positioned within a suction tube of an engine;
- a water supply mechanism coupled to the water injector and configured to supply water to the water injector;
- an air supply mechanism also coupled to the water injector and configured to supply air to the water injector;
- a valve mechanism coupled between the water injector and the supply mechanism where the valve mechanism is configured to selectively supply water from the water supply mechanism and the air from the air supply mechanism to the water injector;
- and
- a control mechanism coupled to the valve mechanism and configured to control the valve mechanism based on operating conditions within the engine.
A water injection device for an engine, comprising:
- a water injector having an injection port within a suction tube of an engine;
- a water supply mechanism for supplying water to the water injector;
- an air supply mechanism for supplying air to the water injector with a compressor driven by power from the engine and a compressed air tank for storing compressed air from the compressor;
- a valve mechanism for mixing together the water from the water supply mechanism and the air from the air supply mechanism to the water injector;
- and
- a control mechanism for controlling the valve mechanism in accordance with operating conditions of the engine.
A water injection device for an engine, comprising:
- a water injector having an injection port within a suction tube of an engine;
- a water supply mechanism for supplying water to the water injector;
- an air supply mechanism for supplying air to the water injector;
- a valve mechanism including a plurality of solenoid valves electronically controlled to mix and simultaneously supply water from the water supply mechanism and the air from the air supply mechanism to the water injector;
- and
- a control mechanism for controlling the valve mechanism in accordance with operating conditions of the engine.
