摘要： PURPOSE:To sufficiently secure a quantity of fuel to be discharged into an engine, by providing a voltage control means for variably controlling a voltage to be applied to a motor for driving a fuel pump according to a battery voltage condition to be detected by a voltage condition detecting means. CONSTITUTION:A voltage condition of a battery 5 is detected by a control unit 11, and when the voltage condition is lower than a predetermined value, the control unit 11 sets a predetermined value Qa=alpha for a suction air quantity Q, and decides the value of the suction air quantity Q, thus controlling opening and closing of a break contact 8b of a relay switch 8. On the other hand, when the voltage condition of the battery 5 is higher than the predetermined value, the control unit 11 sets a predetermined value Qa=beta for the suction air quantity, and decides the value of the suction air quantity Q, thus controlling opening and closing of the break contact 8b of the relay switch 8. Accordingly, even when the voltage condition of the battery is low, a voltage to be applied to a motor 2 for driving a fuel pump 1 may be secured, and thereby a sufficient quantity of fuel to be discharged into an engine may be secured.

摘要： PURPOSE:To restrain the discharge of detrimental gas to control the supply amount of fuel, appropriately, by providing a discriminating means for discriminating whether the speed signals and downstream intake-air pressure signals are within an allowable range of exhaust gas circulation, or not. CONSTITUTION:There are provided a first detecting means 2 for detecting the rotational speed of an internal-combustion engine 1 and a second detecting means 3 for detecting the pressure of downstream intake-air. When a discriminating means 5 judges that the output values of the above-mentioned both detecting means 2, 3 are within an allowable circulation range, an output means 4 issues a circulation output signal. A first valve means 1f controls the circulating amount of exhaust gas, and as well as second valve means 1h carries out fuel supply. With this arrangement the emission of detrimental gas may be restrained, and the output of the engine is maintained appropriately.

摘要： PURPOSE:To improve transient responsive property by igniting in ignition timing for a predetermined time right after running is shifted from idling to non-idling when engine cooling water temperature is lower than a set value in such shift time. CONSTITUTION:Whether or not engine cooling water temperature is higher than a predetermined value is judged in step 130. If it is not, i.e. the engine is cooled, advance is made to step 140, and whether or not a predetermined time has elapsed after running is shifted from idling to non-idling, is judged. When that shift is carried out within that time in cooling the engine, ignition timing right after the shift is used in step 170. Thus, the transient responsive property is improved.

摘要： PURPOSE:To reduce the necessary number of control programs in a control device and minimize the capacity of a ROM, etc. by commonly utilizing program steps of processing the feed-back controls of air-fuel ratio and exhaust gas temperature. CONSTITUTION:A control device 20 receives an oxygen concentration signal from an air-fuel ratio sensor 14, a signal from an exhaust gas temperature sensor 15, etc., and a CPU100 carries out the feed-back controls of air-fuel ratio and exhaust gas temperature in accordance with control programs stored in a ROM108. These controls are carried out under substantially similar processes, and as well the program steps for processing both feed-back controls are commonly used since both control areas are not overlapped together. With this arrangement, the necessary number of control programs in the control device 20 may be reduced so that the capacity of the ROM108, etc. may be minimized.

摘要： PURPOSE:To obtain an internal combustion engine with light weight and less noise and oscillation and being combustible with a dilute air-fuel mixture by providing a hot spot having a resistor wire type heater at the place where the injected fuel passes in the combustion chamber of a Diesel engine so as to control the surface temperature from the outside. CONSTITUTION:The fuel is injected by an injection pump 4 through an injection valve 1 at the near end of the compression stroke, and hits the hot spot 2 provided at the tip of the injection valve, then is heated by the hot spot 2, and flows into a combustion chamber 3 through a hole 12. A resistor wire type heater is used for the hot spot 2, and the electric power is fed from a power supply 6 through a current control circuit 5. The casing of the hot spot 2 is composed of a hollow cylinder section 11 and a cover section 9, and they are coupled by welding after a heating body 7 is sealed. One end of the cylinder section 11 is opened and has a thread section inside to engage with the injection valve 1 and the other end is closed, and a hole 12 connecting to the combustion chamber 3 is provided on the side wall.

摘要： PURPOSE:To certainly judge the anomaly of a transmission passage leading to a pressure sensor from a pressure sensor and a suction pipe by transmitting the pressure in the suction pipe of an internal-combustion engine to the pressure sensor through a connection pipe and judging anomaly if the detected output of the pressure sensor does not vary when the engine load varies. CONSTITUTION:A connection pipe 4 is opened onto the wall of a suction pipe on the downstream side of a throttle valve 3 and is made of rubber for introducing the pressure to a pressure sensor 5. In a controller 7, the pressure Pm in the suction pipe is detected, and anomaly is judged, and the fuel feeding amount to an engine and ignition timing are calculated. In the sensor anomaly judging processing, judgement of anomaly is performed in the following cases: the case where the engine is in cranking operation, not in the normal operation, and the output of the sensor does not vary over a prescribed value, and the case where the engine is in normal operation and the engine load is constant, or the pressure does not vary.
