    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.A smaller ancillary conduit may by-pass the valve member, and a stop valve, sensitive to the pressure differential between the mixture passage and the atmosphere, may shut off both the main conduit and the ancillary conduit when the engine is not operating.The feeding of water into the mixture passage reduces the nitrogen oxides contained in the exhaust gases and improves the fuel consumption.

    摘要： In an exhaust gas recirculation system for an internal combustion engine, a flow control valve is disposed within a recirculation pipe and operatively connected to a pneumatically operated servomotor to control the flow quantity of exhaust gases through the recirculation pipe, and an orifice is disposed within the recirculation pipe upstream of the valve to form a space between the valve and the orifice. A pressure regulator serves to modulate negative pressure from an engine intake manifold to the servomotor on a basis of pneumatic pressure applied thereto and pressure in the space. The pneumatic pressure applied to the pressure regulator is electrically controlled to satisfy the following equation.Pd=f(Pv, N)where the character Pd is the pneumatic pressure applied to the pressure regulator, and the characters Pv and N respectively indicate the negative pressure in the intake manifold and the engine speed.

    摘要： An air intake device comprising a main air intake passage and an auxiliary air intake passage, in which the main air intake passage interconnects the air cleaner to the engine cylinders and the auxiliary air intake passage is connected to the air cleaner at one end thereof and to the main air intake passage at the other end thereof. The equivalent pipe lengths of the main air intake passage and the auxiliary air intake passage are almost the same. An air pulsation control valve actuated in response to the engine load and the engine speed is arranged in the other end of the auxiliary air intake passage. The engine has a helically-shaped intake port comprising a helical portion, an inlet passage portion, and a bypass passage branched off from the inlet passage portion and connected to the helix terminating portion of the helical portion. A flow path control valve actuated in response to the engine load is arranged in the bypass passage. The opening and closing operation of the air pulsation control valve is carried out when the flow path control valve is open.
