Abstract

PURPOSE:To simplify a control means comparatively, and to conduct different control when acceleration and when low speed by mounting each two of throttle-valve opening, revolution-number and suction negative pressure sensors to the engine in which a stopping means is set up to one of two induction or exhaust valves of one cylinder. CONSTITUTION:The stopping means 6, 7 are operated in the full opening and one fourth opening of a throttle valve and at the Ne1 or lower of high revolution and output characteristics are improved at the low speed side, and the engine is similarly stopped in half opening and at the Ne2 of low revolution and output characteristics are improved. When the engine is accelerated in the intermediate opening of the throttle valve, the sensor 15b at low revolution is prepared for operation because suction negative pressure is comparatively low and the sensor 18b is closed, the sensor 15b is closed at the number of revolution Ne2 or higher, and the feeling of acceleration is increased in output characteristics. When the engine is decelerated in the intermediate opening of the throttle valve, suction negative pressure is comparatively high, the sensor 18a is closed, the sensor 15 at high revolution is prepared for operation and opened at the number of revolution Ne1 or lower, and the feeling of deceleration is increased in output characteristics.

One side (the upper one in the figure) is provided with a stop means 17J for stopping its proboscis opening operation and bringing it to the same position as the cylinder t1).
90 Strict stop M (6J is energized as shown in Fig. 2) According to L2ies solenoid valve (6a) to XB, D valve (6a)
When the valve of one of the valves (2+ is opened), the fulcrum of the rocker arm (8) is pushed from its lower side (9) and the control cylinder (II is supported by its outlet OD) opened. In this way, the pressure oil introduced into the cylinder curve through the inlet α side is discharged through the mortar outlet Qll, and the pressure inside the cylinder curve becomes low, causing the clay figurine to splash 191 Fi. The spring strength is reduced and the fulcrum is free to move downward, in other words, the arm (8) is rendered inoperative.
