Abstract: Fuel is injected in synchronism with the crank angle. In addition, an engine acceleration state is detected from the second-order differential value of the intake-pipe pressure, and the quantity of the asynchronous fuel injection in which fuel is injected in asynchronism with the crank angle is increased in an early stage of acceleration but is decreased after the early stage of acceleration. Moreover, no asynchronous injection is carried out in a low engine speed region. It is thereby possible to obtain an optimum air-fuel ratio in accordance with the engine acceleration state.

Abstract: An apparatus for controlling a control parameter of a multicylinder internal combustion engine so that a cycle-by-cycle torque variation is equal to a target torque variation after an inter-cylinder correction for bringing the quantities of torque generated in a plurality of cylinders into agreement is performed. In the engine control apparatus, a modification part modifies a range within which a torque variation correction factor can change into a narrower range, when it is judged that the inter-cylinder correction has not been completed, so that a control part generates an appropriate control parameter based on first correction factors calculated by a first calculation part and the torque variation correction factor calculated by a second calculation part even when the inter-cylinder correction routine has not been completed.

Abstract: A forward flow region in which forward intake air currents are produced and a reverse flow region in which reverse intake air currents are produced are formed in the throttle bore of a throttle body 3 included in an internal-combustion engine, and the boundary between those regions extends below a throttle valve 5. A fuel vapor control system for an internal-combustion engine has a purge tube 13 joined to the throttle body 3 to supply fuel vapor into the throttle body 3 and is provided with an opening 22 which acts as a purge port. The opening 22 is positioned at a distance from the inner surface 21 of the throttle body 3 defining a throttle bore on the boundary between the forward intake air currents and the reverse intake air currents. Fuel vapor jetted through the opening 22 of the purge tube 13 into the throttle bore flows toward an intake manifold 2, diffusing into both the forward intake air currents and the reverse intake air currents from the boundary between the intake air currents. Accordingly, the fuel vapor is distributed evenly through the intake manifold 2 to the cylinders, so that increase in the difference in air-fuel ratio between the cylinders can be suppressed. The purge port can relatively easily be formed, because the purge tube 13 provided with the purge port is fitted closely in a bore formed in the throttle body 3.

Abstract: An ignition timing control apparatus for a spark ignition internal combustion engine for a vehicle having a manually operated transmission system. The apparatus includes an ignition control system for controlling ignition timing in such a manner that the timing is advanced when the engine speed drops due to engagement of the clutch of the transmission apparatus to begin the initial movement of the vehicle. The drop in the engine speed is sensed by detecting whether a second order difference value of the engine speed is lower than a reference value. This realizes quick control of the engine speed.
