Title: Water injection system for internal combustion engine
Inventor: VINOKUR MICHAEL
IPC: F02B47/02
Filed: 1983-03-28
Granted: 1987-10-22
Abstract: A novel pump suitable for use in a water injection system of an internal combustion engine is described. The pump controls the rate of flow of water injected into the engine. The pump includes a variable pressure inducing means for pressurizing the water contained in the pump. The variable pressure inducing means is responsive to negative back pressure developed in the intake manifold of the engine and varies the pressure of the water in accordance with changes in the negative back pressure of the manifold. As the negative back pressure decreases, the pressure of the water increases which in turn increases the flow rate of fluid from the pump into the engine. There is also disclosed a pressure sensitive nozzle for controlling the flow of fluid exiting from the nozzle as a function of fluid pressure. The nozzle includes an auxiliary fluid flow path through the nozzle that has an inlet opening of variable size. The nozzle further includes a pressure sensitive piston that provides a primary fluid flow path through the nozzle. The pressure sensitive piston normally blocks the inlet of the auxiliary flow path. In response to a pressure build up above the predetermined value in the primary fluid flow path of the piston, the piston moves thereby increasing the size of the inlet of the auxiliary flow path as the pressure build up in the primary flow path increases above the predetermined value.
