Abstract
The present invention is concerned with apparatus for the introduction of fluids into the inlet gas stream of an internal combustion engine whereby variations in pressure in a combustion chamber control the fluid injected into the inlet gas stream. Pressure sensing means communicate with at least one combustion chamber of an internal combustion engine, and pump means responsive to said pressure variations sensed by said sense means to pump fluid from the fluid supply means to inject said fluid into said inlet gas stream of said engine.
Claims10
An internal combustion engine having means for feeding fuel into each combustion chamber of said engine and apparatus for the introduction of fluids other than fuel into an air inlet passage of said engine, which apparatus comprises:
- a supply of fluid other than fuel;
- injection means for injecting said fluid into said air inlet passage of said engine prior to entering a combustion chamber of said engine;
- means for sensing pressure variations in at least one combustion chamber of said engine;
- a pump communicating with and responsive to said sensing means for delivering varying amounts of fluid from said fluid supply to said injection means, said amount of fluid being determined by the pressure in said at least one combustion chamber such that the amount of fluid supplied by said apparatus to said air inlet passage varies as a function of the pressure in said at least one combustion chamber of said engine.
