Apparatus for feeding water into the air/fuel mixture passage of an internal combustion engine |
摘要 |
Apparatus for feeding water to the air/fuel mixture passage between the air/fuel mixing device and combustion chamber of an internal combustion engine including a main conduit for supplying water to the mixture passage, a valve member for opening and closing the conduit, the valve member being biased into the closed position, a diaphragm communicating on one side directly to the mixture passage for actuating the valve member to an open position and on the other side through a pressure delay chamber with the mixture passage, wherein the conduit is opened only by a relatively abrupt increase in pressure in the mixture passage, and the closing is delayed until the pressure equalizes across the diaphragm. Water may be supplied to the conduit directly by a pump, or by a pressure differential or by means of a reservoir having access to a water supply. Water may be pumped into and out of the reservoir by a diaphragm or a piston in the reservoir, the diaphragm being actuated by a pressure differential, or the piston being actuated by a pressure differential or by the accelerator.
