    摘要： A full time lean air fuel mixture running spark ignited air cooled aircraft piston engine. In one embodiment, a drop-in substitution is provided for an equivalent make, model, and engine size, wherein the new, rebuilt, or reconfigured engine provides as much or more horsepower when compared to the original engine, but runs at a lean air fuel ratio condition during normal operating modes, including takeoff, climb, and cruise, thus saving significantly on fuel. In yet another embodiment, a drop-in substitution having a somewhat larger cylinder displacement volume may be provided to attain equivalent or enhanced maximum horsepower while operating at lean air fuel ratios. Enhanced engine life may be anticipated, since cylinder head temperatures (CHTs) may be reduced, compared to engines using rich air fuel ratios for climb and cruise conditions. Aircraft using such engines are also disclosed.

    摘要： A method for operating an internal combustion engine using externally supplied ignition, having a manually operable transmission, in which a torque produced by the internal combustion engine is able to be influenced via at least one control variable. An impending shifting process of the manual transmission and/or another operating situation of the internal combustion engine, during which a temporary lowering of the torque produced by the internal combustion engine is required and/or desired, is detected, and, as a function of the detection, the torque is lowered by changing at least one control variable of a fuel path.

    摘要： This invention makes known by a method of the ignition, which is energy conservation and environmental protection. Its characteristic is that the ignitor can fire possibly to close with the point of ignition which is under the control of digital single-chip microcomputer-controlled circuit in some working conditions. The degree of approach in proportion as the speed of operation, so that the engine output speed namely the engine output power is highest. The present invention needn't preset the so-called the best ignition curve which does not exist, but it adjusts the ignition time automatically base on the working conditions of engine. This method ensures the present system could fire at the best time in any working conditions. This technology applies to products which use gasoline engine, for example, cars, motorbikes.

    摘要： When an air conditioner is turned on during homogeneous operation, an equivalence ratio correction factor .DELTA. .phi. is increased sharply and suddenly in such a manner as to show a jump for thereby increasing an engine output torque, and thereafter is decreased gradually with increase of a cylinder intake air quantity, whereby to maintain the engine output torque constant. However, when switching to a homogeneous mode occurs in the middle of the above control, switching to proper torque correction is not carried out at the time of a homogeneous combustion mode, i.e., torque correction by the use of ignition timing but the torque correction by the equivalence ratio correction factor .DELTA. .phi. continuously. By this, in contrast to the case in which the torque correction is switched to one that is carried out by the use of ignition timing correction quantity, a sharp and sudden variation of engine output torque can be prevented. In the meantime, after completion of the torque correction by the above mentioned control, the torque correction at the time of the homogeneous combustion mode is carried out by ignition timing correction. Further, when the combustion mode is switched to stratified combustion during execution of torque correction by ignition timing correction at the time of the homogeneous combustion mode, the torque correction is switched to one that is carried out by the use of the equivalence ratio correction factor simultaneously with switching of the combustion mode.

    摘要翻译： 当在均匀运转时空调机开启时，等效比率校正系数DELTA phi以显示跳跃的方式急剧急剧地增加，从而增加发动机输出转矩，然后随着气缸的增加逐渐减小 进气量，从而维持发动机输出转矩恒定。 然而，在上述控制的中间发生切换到均匀模式时，在均匀燃烧模式时不进行切换到适当的扭矩校正，即通过使用点火正时进行转矩校正，而是通过使用点火正时的转矩校正 等效比率校正因子DELTA phi连续。 由此，与通过使用点火正时校正量进行转矩修正的情况相反，可以防止发动机输出转矩的急剧变化。 同时，在通过上述控制完成扭矩校正之后，通过点火正时校正来进行均质燃烧模式时的扭矩校正。 此外，当在均匀燃烧模式时通过点火正时校正在执行扭矩校正期间将燃烧模式切换到分层燃烧时，转矩校正被切换为通过使用当量比校正因子同时进行的转矩校正 随着燃烧模式的切换。
