摘要： PURPOSE:To enable setting of an engine matched with a change in a combustion state produced along with a fluctuation in an exhaust pressure and to prevent production of a fluctuation in an output and the occurrence of abnormal combustion, by a method wherein a lead angle amount of an ignition timing, EGR characteristics, and control properties of a fuel amount are varied depending upon the size of diameter varied by a diameter varying means. CONSTITUTION:A switching valve 18, when the number of revolutions of an engine is 3,000rpm, opens an exhaust gas introducing passage 17 for high speed. In which case, since an exhaust pressure is decreased, control is effected so as to prevent the decrease in the exhaust gas. In a low speed range (where the passage 17 is closed), ignition lead angle properties have inclination slightly lower than lead angle characteristics of a high speed range. In a low speed range, EGR chracteristics is decreased over that in a high speed range. Control of a fuel injection valve 14 is effected by a map control system by means of an intake air amount, detected by an airflow meter 12, and the number of revolutions of an engine detected by a rotation sensor 26.

摘要： PURPOSE:To increase the charging efficiency of an engine, by reducing resistance to the intake-air flow by providing a by-pass passage by-passing an intercooler connected to an intake passage on the downstream side of a supercharger so that intake air is not passed through the intercooler at the time of nonsupercharged operation of the engine. CONSTITUTION:A natural air intake passage 14 and a supercharging passage 18 having a supercharger 19 are connected to a combustion chamber 6, and an intercooler 20 through which cooling water is circulated by a water pump 31 is connected to the supercharging passage 18 on the downstream side of the supercharger 19. At the time of high-load operation of an engine, a clutch 29 for driving the supercharger 19 is coupled, and supercharging air is supplied to the combustion chamber 6 after it is passed through the intercooler 20 and cooled thereby. At the time of low-load operation of the engine, on the other hand, the clutch 29 is uncoupled by a control unit 33 and the supercharging passage 18 is closed substantially, so that intake air is supplied only through the natural intake passage 14 by-passing the supercharger 19. Thus, since resistance to the intake-air flow caused by passing intake air through the intercooler is removed, it is enabled to raise the charging efficiency of the engine.

摘要： PURPOSE:To improve the response of a turbocharger at the beginning of supercharging, by releasing the pressure of a supercharging passage down stream to the turbocharger at the time of non-supercharging to prevent the load upon the turbocharger from rising due to the increase in the pressure upstream to the turbocharger. CONSTITUTION:In the unsupercharged low-load operation of an engine E including its idling, a shutoff valve 17 is closed and another shutoff valve 19 is opened so that air pressurized by a turbocharger 14 is fed to an ordinary intake passage 11 through a communication passage 18. As a result, the pressure of a supercharging passage 13 downstream to the turbocharger 14 is kept from rising. The load upon the turbocharger 14 is thus prevented from increasing, to keep its rotational frequency high. For this reason, the response of the turbocharger 14 at the time of shifting to the supercharging of the engine E is imporved.

摘要： PURPOSE:To raise the charging efficiency of an engine and to thereby prevent drop of the engine output in the operational range of the engine when switching of a variable port is effected, by opening a second intake port fully at the time of high-load operation of the engine simultaneously with the opening of a control valve, and delaying the timing for closing the second intake port when the control valve is opened to that of a first intake port. CONSTITUTION:The engine speed for switching a second intake port at the time of high-load operation of an engine is set in the range of 3,500-5,000rpm since it is necessary to keep a control valve open at the time of engine operation higher than 5,000rpm and to close the control valve for preventing blow-back of intake air when the engine speed is lower than 3,500rpm. The timing for closing the second intake port when the control valve is open is delayed to that of a first intake port so as to raise the charging efficiency. At the engine speed for switching a variable port when a high-load intake port 4 is opened, expansion wave is produced in a first and a second low-load intake passages 20a, 20b when supply of intake air from a low-load intake port 3 is started and transmitted as secondary pulsation wave of compression wave to the low- load intake ports 3 of cylinders 1A, 1B just before they are closed completely. By thus supercharging the engine and raising the charging efficiency, it is enabled to increase the engine output by preventing the drop of the same.

摘要： PURPOSE:To improve the output of an engine by simple constitution without causing any necessity for a supercharger or the like, by propagating a compression wave, generated when intake ports in one cylinder are opened,and a secondary pulsating wave, generated due to a start of intake, to intake ports immediately before their full closing in the other cylinder when the two-cylinder engine of side intake port type is driven at a high speed. CONSTITUTION:When an engine is driven at a high speed, a compression wave, generated in a passage 18b when intake ports 3a, 3b of, for instance, a cylinder 1B are opened, is propagated to intake ports 3a, 3b immediately before their full closing and operated with a 180 deg. phase difference in a cylinder 1A via a passage in an accurate length between the intake ports of the both cylinders. Simultaneously, an expansion wave, generated in a passage 18a due to a start of intake of the cylinder 1A, is propagated to the intake ports 3a, 3b immediately before their full closing in the cylinder 1A by repeating inversion and reflection through a passage in an adequate length between the intake ports and an expansion chamber 23. Similarly, a compression wave, generated in the cylinder 1A, and a secondary pulsating wave, generated in the cylinder 1B by its own action, are propagated to also the cylinder 1B, and a supercharge is performed, thus capable of simplifying construction of the engine.
