Title:
不燃性流体噴射を用いてエンジンを作動するための装置及び方法
Document Type and Number:
Japanese Patent JP2011526342
Kind Code:
A
Abstract:
A water injector has a plug end fitting for installation on the individual combustion chambers of an internal combustion engine of the spark ignition or compression ignition type, though which a quantity of water or other non-fuel fluid is injected into the combustion chamber. The temperature and combustion pressure of each combustion chamber as well as the temperature, pressure and humidity of the atmosphere may be monitored and used to control the quantity of water injected into the combustion chambers such that the engine operates at internal combustion conditions equivalent to those occurring at the standard ISO rated atmospheric conditions and thus delivers its ISO rated output regardless of atmospheric conditions. A nozzle is fitted to the plug end of the water injector containing a plurality of openings to inject the water or other non-fuel fluid into the combustion chamber in a predetermined spatial spray pattern. For spark-ignited engines, a high energy pre-chamber may be integrated with the water injector to facilitate ignition when water is injected into the compression cycle. For Diesel engines, the water injection nozzle may be provided with a spatial spray pattern that complements that of the Diesel injector within the cylinder. Engine efficiency may be further enhanced by using an exhaust heat exchanger to preheat at least some of the fluid being injected into the engine and by combining a first injection of fluid at a lower temperature for controlling combustion and otherwise improving efficiency during the compression stroke with a second injection of fluid at a substantially higher temperature during the expansion stroke for maintaining a high rated output during non ISO conditions.
