摘要： Under a partial load, a pumping loss is reduced by a stratified combustion to enhance a fuel consumption, and during the maximum output operation, the output is increased by a premixture combustion, and the output of an engine is controlled, thereby enhancing the drivability. Under the partial load, an ignition source is provided in the vicinity of a fuel injection valve, and after the fuel is injected, the mixture is ignited, and a resulting flame is caused by a spray of the fuel to spread into a cylinder, thereby effecting a stratified combustion. When the load increases, so that soot and so on are produced in the stratified combustion, the fuel injection is effected a plurality of times in a divided manner, and a premixture is produced within the cylinder by the front-half injection, and a flame, produced by the latter-half injection, is injected into the cylinder to burn this premixture.

摘要： An engine drive torque controller has a first mode in which torque is controlled by varying air-fuel ratio within a range greater than stoichiometric and a second mode in which torque is controlled while maintaining a substantially fixed air-fuel ratio. The control modes are selected to keep nitrogen oxide emissions low. The torque controller also changes the air-fuel ratio during transmission shifting to prevent variations in torque.

摘要： The combustion, especially a lean mixture, in an internal combustion engine is improved by providing an additional air introducing device. The device comprises an air by-pass pipe introducing additional air independently from the airflow through an intake manifold and having its outlet in the manifold at the vicinity of an intake valve and an air by-pass valve for adjusting the flow rate of the additional air through the by-pass pipe according to operational conductions of the engine. As a consequence, during the suction stroke of a cylinder, additional air, stagnated in the vicinity of the intake valve, is at first drawn in and then an air-fuel mixture supplied by a fuel injector is supplied to the cylinder. Accordingly, the stratification of combustible fluid is performed within the cylinder, in which an ignition plug is exposed to an upper phase formed by the mixture.

摘要： On an input and an output shafts of the transmission, there are provided a plurality of gear pairs which have different reduction ratios. One of the gears of the gear pair having the smallest reduction ratio is operably connected with the input shaft through a multi-disk clutch, and the torque transmitted from the input shaft to the gear can be controlled by adjusting the thrusting force applied to the clutch. When the selection of the gear pair is changed, the gear pair under operation at present is brought into the neutral condition and, at the same time, the thrusting force of the clutch is increased. Thereby, the torque of the input shaft is transmitted to the output shaft through the clutch and a rotational synchronism of the input and output shafts is advanced by adjusting the thrusting force. When the rotational synchronism is completed, the gear pair to be selected is brought under the operation.
