摘要： An exhaust gas recirculation system for an internal combustion engine includes an exhaust gas recirculation passage for communicating an exhaust port with an intake passage through a recirculation flow control valve. The recirculation system according to the invention comprises a timing valve in the recirculation passage adapted to open at specified moments for extracting exhaust gases containing highly concentrated hydrocarbons. According to the invention, moreover, the exhaust port is concentrically divided into a plurality of ports to extract exhaust gases having high concentrations of hydrocarbons from the outermost divided port adjacent to the inner peripheral walls of the exhaust port to recirculate them into intake mixtures, thereby reducing the concentrations of hydrocarbons and nitrogen oxides in exhaust gases and thus fuel consumption.

摘要： A fuel injection apparatus for an internal combustion engine has at least one fuel injection valve. An annular or ring-shaped electrode is mounted near the fuel injection valve to encircle the injected fuel. A high voltage generator produces an electric field between the electrode and the fuel injection valve as well as a surrounding wall which are both connected to the ground. Electrified fuel particles are finely atomized and prevented from attaching onto the surrounding wall to improve the operation, starting characteristic, and transient response of the engine.

摘要： Apparatus for controlling the rotational speed of an I.C. engine in an idling operation comprises a constant pressure valve, a solenoid valve, and a control signal generator. A constant vacuum pressure produced by the constant pressure valve is modified by atmospheric pressure by means of the solenoid valve which is actuated by a pulsating signal produced in the control signal generator. The pulse width of the pulsating signal is variable in accordance with a detected engine speed. The modified vacuum pressure is coupled to a chamber of a main valve of a conventional boost controlled deceleration device to control the amount of air-fuel mixture supplied to the intake manifold of the engine.

摘要： To effect EGR in an internal combustion engine with the maintenance of adequate balance between the suppression of NO.sub.x formation and preservation of stable engine operation, the condition of combustion in the engine is taken as the basis of feedback control of the volume of recirculated exhaust gas so as to correct a deviation of the total amount of the recirculated exhaust gas and unexhausted combustion gas in the combustion chamber from a desired amount. The intensity of an ionic current produced upon combustion in each combustion chamber, the magnitude of mechanical vibration of the engine or the frequency of misfire in a combustion chamber is detected as an exact indication of the condition of combustion.

摘要： In mass flow rate measuring apparatus wherein the fluid is ionized at intervals at a predetermined point of the fluid passage, a voltage is sensed when the ionized flow mass is collected by an electrode located downstream from the ionization point. Electromagnetic radiation, generated in response to the generation of a strong electric field that ionizes the fluid, is prevented by means of a gate circuit from being sensed as a signal for triggering a time measuring device. The signal from the gate circuit is coupled to a voltage sensing circuit that detects a point near or at the peak value of successive voltage waveforms to signal the time measuring device as a point of ion collection.

摘要： Flow rate in a fluid passage is measured by making corona discharge in a section of the fluid passage to cause partial ionization of the fluid and measuring a current produced in a DC circuit including a pair of electrodes disposed in the fluid passage downstream of the corona discharge section. Variations in the relationship between the measured current and the flow rate with difference in inherent conductivity among fluids are evadable by measuring a basic current through the DC circuit while the corona discharge is interrupted and regulating a voltage for either ionization or measurement based on the basic current.
