摘要： A driving mechanism for a travelling toy automatically runs backwardly when its forward movement is hindered by an obstacle. The driving mechanism includes a rotatable sun gear which selectively drives a wheel shaft through either a first or second oppositely facing crown gears secured to the wheel shaft. A pivotal arm carrying an intermediate planetary gear effects drive through the sun gear and planetary gear to a selective crown gear in dependence on the position of the arm. The arm position is controlled by engageable steps and control dogs.

摘要： The invention precisely achieves an air fuel ratio control precision in each of operating regions of an engine, particularly a demand air fuel ratio at a time of an engine transition. In a fuel control system correcting a basic fuel amount in such a manner as to estimate a fuel adhered to an air intake pipe of an engine and an evaporated fuel from the adhered fuel so as to achieve a demanded air fuel ratio, a temperature of a fuel adhered portion is estimated on the basis of an amount relation between the fuel to be adhered and the already adhered fuel, or a heat quantity balance. A fuel adhesion amount and a fuel evaporation amount are determined on the basis of the estimated temperature.

摘要： Factors affecting the response time of a transfer system from the combustion of injected fuel to the detection of its oxygen concentration include a stroke delay time due to an engine speed, the dependence of an LAF sensor response time on an exhaust gas flow rate, a response time change of the LAF sensor due to its deterioration with time, and the like. If a hyperplane of the sliding mode is fixed without considering the above-mentioned factors affecting the response time of the transfer system, an overshoot or oscillation of a feedback system may occur at low speeds of the engine even if preferable feedback responsiveness can be achieved, for example, at high speeds of the engine. This results in aggravated exhaust emissions, degraded drivability due to torque fluctuations, and fluctuations in idle speed.A hyperplane used in a control system for providing feedback control of an air-fuel ratio through sliding mode control is varied based on the factors affecting the response time of the control system within a range in which the control system can be stabilized.

摘要： At the start-up of an engine, the ignition timing and the air-fuel ratio are controlled to prevent overload onto the volume of ISC air and decreased torque and torque difference.The fuel condition based on the amount of ignition timing correction to inhibit rotational fluctuation during idling is determined and the fuel quantity based on the result is corrected.Right after an engine has started and until a pilot burner is created in the heat spot of the catalyst, the ignition retard control is mainly executed, and at the time when it is determined that a pilot burner has been created in the catalyst's heat spot, the lean air-fuel ratio control is to be executed instead of the ignition retard control. Furthermore, when the ignition retard control changes to the lean air-fuel ratio control, the state transition control is executed along the equivalent ISC air volume line so as not to cause torque fluctuation.

摘要： An engine control apparatus controls an intake air flow based on the engine torque or the fuel injection amount. A variation of the A/F ratio and deterioration of a driving “feel” owing to the response delay of air intake against the fuel injection is suppressed. The phase of fuel injection is caused to fit that of the air intake phase by delaying the fuel injection or by speeding up the air intake.
