  • Patent number: 5934249
    Abstract: The EGR gas flow is established based on the difference between an assumed value and a control target value of non-air components partial pressure calculated from target control values such as engine torque and at the same time the intake air flow passing through a throttle valve is established based on the difference between an assumed value and a control target value of air components partial pressure and based on the air components within EGR gas. Further, based on thus established EGR gas flow and the intake manifold pressure, the operating amount of an EGR actuator is calculated and based on thus established air flow passing through the throttle valve, the operating amount of an throttle actuator is obtained. Further, based on an estimated value of air components partial pressure, a final basic fuel injection amount is determined.

  • Patent number: 5785031
    Abstract: In an in-cylinder fuel injection engine capable of selectively switching a combustion strategy from a stratified charge combustion to a homogeneous charge combustion and vice versa, when a coolant temperature at engine start is lower than a specified temperature, the combustion strategy is established to be a homogeneous charge combustion mode and this homogeneous charge combustion mode is held until the coolant temperature reaches the specified temperature. While the coolant temperature is higher than the specified temperature and lower than a warm-up completion temperature, the combustion strategy is switched from homogeneous to stratified by lowering the engine load from a high load area to a low load area so as to improve emissions and fuel economy.

  • Patent number: 5676108
    Abstract: A combustion control system and method of a four cycle direct injection engine includes an igniter for igniting simultaneously in two cylinders, a firing cylinder and an off-firing cylinder. In the combustion control system, it is judged whether or not the spark discharge period following the ignition timing overlaps with the fuel injection period following the fuel injection starting timing. If it is judged not to overlap, the fuel injection starting timing determined based on the engine speed and the fuel injection amount is let be a final fuel injection starting timing. If it is judged to overlap, the spark discharge ending timing is obtained from the ignition timing and the spark discharge period and this spark discharge ending timing is let be a final fuel injection starting timing.

  • Patent number: 5642705
    Abstract: In a catalyst activation control system for a direct fuel injection engine for igniting primary fuel injected into each cylinder, an additional fuel is injected at least once into each cylinder from an early period to a middle period of an expansion stroke of the primary fuel combustion in accordance with the engine operating conditions, to fire the additional injection fuel by flame propagation of the preceding fuel combustion (without re-ignition) for eliminating misfire, so that an exhaust gas temperature can be raised stably to activate catalyst for purification of exhaust gas. Further, any one of the additional fuel injection method and an ignition timing retarding method can be appropriately selected in accordance with the engine operating conditions for economization of fuel.

  • Patent number: 5441026
    Abstract: When a damage in a high pressure line of a fuel pressure control system for a high pressure fuel injection engine is detected the fuel pressure is reduced to prevent fuel from blowing out of the damaged part. An acceleration detected by the acceleration sensor is compared with a set value. When the detected acceleration exceeds the set value, the system determines that such an emergency as a collision has happened, fully opens a solenoid type high pressure regulator provided downstream of the high pressure line of fuel system and stops the operation of a feed pump provided in a low pressure delivery line. Thereupon, the feed pump stops delivering the fuel to a high pressure fuel pump. On the other hand, the high pressure regulator is in a fully opened position. Thus, the fuel pressure in the high pressure line is relieved to a fuel tank.

  • Patent number: 5394844
    Abstract: Based on the output signal of the fuel sensor, it is judged whether or not the fuel (liquid fuel) is detected in the high pressure fuel system. When the fuel is detected, the count value for counting the detecting time is compared with the predetermined value. If the count value is equal to or larger than the predetermined value, the electromagnetic type high pressure fuel regulator is rendered closed and the starter motor prohibition flag is cleared to admit energizing the starter motor. As a result of this, the engine is permitted to be started and thus the high pressure fuel pump starts to produce the high pressure in the high pressure fuel system, whereby a sticking or a scuffing in the fuel pump due to poor lubrication can be prevented and an overshoot of the fuel pressure or a void injection in the fuel injector can be avoided.
