摘要： Low mass hydraulic and mechanical valve lifters are shown and described. The lifters are of oblong configuration for reduced mass, with straight or narrowed sides connecting longitudinally spaced ends having depending semi-cylindrical end walls that are received in similarly shaped end portions of lifter gallery openings to absorb all longitudinal and lateral side loads. The lifters are preferably made by investment casting of steel alloys. The investment casting permits the use of thin semi-cylindrical walls at each end of the valve lifters which also have internal reinforcing ribs extending on their undersides.

摘要： A low mass two-step valve lifter has concentric inner and outer cylindrical cam followers engagable by radially disposed axially aligned lock pins in the outer high lift follower. Both inner and outer followers have cylindrically crowned cam engaging surfaces for high lift capability and low load eccentricity. The lock pins are positioned on the lifter thrust axis normal to the direction of the engine camshaft axis and the skirt has upward seal extensions and downward extending skirt portions adjacent the lock pin openings to maintain seal area. Other skirt portions are cut away to reduce weight. Vent holes in the lock pins discharge collected oil that might interfere with fast pin engagement. A separate passage is provided to feed oil to a hydraulic lash adjuster disposed in the inner follower cylinder. A single guide pin aligns the dual followers with the external bore oil ports and the camshaft cams. Additional features are also disclosed.
摘要翻译：低质量两级阀提升器具有同心的内外圆柱凸轮从动件，其通过径向设置的轴向对准的锁定销接合在外部高升程跟随器中。内部和外部跟随器具有圆柱形凸起凸轮接合表面，用于高提升能力和低负载偏心率。锁定销定位在垂直于发动机凸轮轴轴线方向的升降推力轴上，并且裙部具有向上的密封延伸部和与锁定销开口相邻的向下延伸的裙部以保持密封区域。其他裙部被切除以减轻重量。锁定销中的排气孔排出收集的油，这可能会干扰快速销接合。提供单独的通道以将油供给到设置在内随动缸中的液压间隙调节器。单引导销将双跟随器与外孔油口和凸轮轴凸轮对齐。还公开了另外的特征。

摘要： Small engine control is provided in which a manual selection of an engine operating level, such as from a positioning of a movable selector between a discrete number of selection settings is used to reference open-loop fuel, air, and ignition timing commands for application to respective actuators in accord with simple yet accurate and flexible engine control. Control precision, sensitivity, and stability are enhanced through engine parameter feedback control, wherein any of the open-loop air, fuel and ignition timing commands may be adjusted in accord with a difference between a feedback signal and a target value.
