摘要： An intake manifold for a multicylinder internal combustion engine having fuel supplying means such as a fuel injection device or a carburetor includes a branch intake conduits each communicating with one of the cylinders of the engine, an extension tube connected to a primary suction conduit of the carburetor, and an incoming fuel charge heating device mounted on the bottom of the intake manifold. The extension tube has a curved portion in its wall directed toward a part of the surface of the bottom of the intake manifold at which the axial center lines of the branch intake conduits gather together and cut to form an open end of the extension tube. The incoming fuel charge heating device has a heating surface disposed near the open end of the extension tube, which is smoothly curved toward the bottom of the intake manifold. The open end of the extension tube is disposed on a plane forming an acute angle with the wall of the tube at the outermost edge of the open end and contiguous at the innermost edge thereof with a straight portion of the wall of the tube, as viewed in cross section. The incoming fuel charge heating device may include positive-temperature-coefficient thermistors.

摘要： A flexible barium titanate ceramic PTC heater for use in, for example, an intake pipe of an internal combustion engine to heat the air-fuel gas mixture is formed as a thin disc-shaped ceramic sheet constituted by a plurality of individual coplanar ceramic segments having interior edges positioned in spaced side-by-side relationship. The juxtaposed edges of the ceramic segments are united to each other by a flexible, heat-resistant, electrically non-conductive rubber band disposed in the space between the segments and bonded thereto by an electrically non-conductive adhesive to form the segments into a thin disc-shaped sheet which can be flexed without causing flexing of any of the individual segments. The ceramic heater is positioned in a metallic casing with one planar face thereof bonded to the inner surface of the casing by an electrically conductive adhesive. A stainless steel wool cushioning member engages the other planar face of the ceramic heater to support the heater in the metallic casing.

摘要： A fuel evaporator for an internal combustion engine is comprised of a metallic casing which is composed of a heating plate portion and a supporting portion projecting from the outer periphery of the heating plate portion downward, a heating element fixed to the heating plate portion within the casing, an insulating and adiabatic covering member which covers the supporting portion and an electrically connecting means which connects the heating element and a battery.The supporting portion of the casing is inserted in a hole formed in an intake pipe so that the heating plate portion is exposed therewithin.Since the supporting portion of the casing is covered with the insulating and adiabatic covering member, very little of the heat of the heating element is dissipated from the supporting portion into the intake pipe.By forming the supporting portion into a plurality of strip shaped legs, the heat escaping therefrom can be further reduced.

摘要： A fuel evaporator comprises a metal member composed of a pipe portion and a flange portion, a heating element made of PTC ceramic, which is closely adhered to the metal member and an electric connector for electrically connecting the heating element and an electric power source. The metal member is supported by an insulating member which is interposed between an air-fuel passage and an intake manifold. The fuel film flow flowing downwards along the wall of the air-fuel passage is received by the flange portion of the metal member and is heated by the heat transmitted from the heating element. Consequently, unvaporized fuel is effectively evaporated.

摘要： An internal combustion engine has an evaporated fuel purge system for directly feeding evaporated fuel of a fuel tank into an intake pipe of the engine during the engine is running. This system comprises a purge control valve for opening or closing a flow line which connects an upper space of the fuel tank with the intake pipe, a controller for controlling the operation of the valve, a throttle section formed in series with the purge control valve, and pressure and temperature sensors which are located on the upstream side of the throttle section for detecting a pressure and a temperature of the evaporated fuel. When a value detected by the pressure sensor exceeds a predetermined value of pressure for providing a critical pressure ratio at which a flow rate of the evaporated fuel at the throttle section substantially equals to a sonic velocity, the controller opens the purge control valve to cause a purged flow of the evaporated fuel whose flow rate is constant. Simultaneously, the controller calculates a purged flow rate of the evaporated fuel from the detected values of the pressure and temperature sensors and a time period during which the purge control valve is opened. On the basis of the calculated purged flow rate, a reduction correction is made to an amount of the fuel to be supplied to the engine in order to maintain an air-fuel ratio in the optimum condition. The calculated purged flow rate may be indicated.

摘要： A pump including a plunger slidably disposed in a pump body, a transmitting member connected to the plunger, a coil spring which urges the plunger, and a cam urging the plunger against the coil spring. The plunger defines a pump chamber in the pump body. The coil spring urges the plunger in a direction such that the plunger contracts the pump chamber. The cam rotates in synchronization with the rotation of the engine and engages with the transmitting member for part of the cycle of the rotation of the engine so that the plunger increases the volume of the pump chamber. The cam releases the plunger in the remaining cycle of the rotation of the engine to allow the coil spring to urge the plunger so that the plunger displaces in a direction to reduce the volume of the pump chamber.

摘要： A piezoelectric fuel injector for use in fuel injection systems of spark-ignition engines is provided with a normally closed valve assembly in the form of a reed valve. The valve assembly includes a valve plate having one or more outlet ports having an overall cross-sectional flow area sufficient to ensure an unobstructed flow path therethrough. The valve assembly also includes a generally flat, thin, resilient closure member cooperating with the valve set of the valve plate. The pressure wave created in the fuel in the pumping chamber upon excitation of the piezoelectric actuator propagates into the outlet ports to directly reach the thin closure member, which readily resiliently yields to permit a desired amount of fuel to be injected into the engine cylinders. The fuel injector is particularly suitable to be operated by a high-frequency drive signal in order to ensure precise metering of fuel quantity over a wide range of engine operating conditions.

摘要： A fuel injector for an internal combustion engine, the injector being actuated by a piezoelectric actuator. The piezoelectric actuator operates a piston, which changes the volume of a pump chamber formed between the piston and a nozzle needle. The nozzle needle moves up and down in response to a pressure in the pump chamber to open and close a port for injecting fuel. The piston is pressed toward the pump chamber by a fluidic force or a spring force and so on.

摘要： A fuel injection system comprising a fuel injection pump, at least one fuel injection nozzle connected thereto, and a control device for varying the rate of injection of the system according to varying engine parameters. The control device has a variable volume chamber, the volume of which is varied by a piston located by a piezoelectric actuator. The variable volume chamber and a pumping chamber of the pump is intermittently connected by a passage which is specifically designed in such a manner that the fluid communication between the chambers, during the delivery stroke of a pump plunger, is provided only for an initial stage of the delivery stroke. A rate of injection is controlled in the initial stage to perform a pilot injection. In the subsequent stage, in which there is no need for rate-of-injection control, the variable volume chamber is isolated from the pumping chamber in order to relieve the piezoelectric actuator from an excessively high fuel pressure that would cause degradation of the piezoelectric elements.
