Abstract: A cooling control unit for a water-cooled multi-cylinder internal combustion engine having a cylinder deactivation mechanism for controlling the flow of coolant to prevent the internal combustion engine from being incompletely warmed up when the internal combustion engine returns to its operating condition with all of the cylinders being activated. A communicating passage communicates with a normally activated cylinder coolant jacket as a coolant passage formed for normally activated cylinders and a deactivation-programmed cylinder water jacket as a coolant passage formed for the deactivation-programmed cylinders to communicate with each other, and through which the coolant flows. A bypass passage diverges from the communicating passage and bypasses the deactivation-programmed cylinder coolant jacket. A diversion control valve is provided in a diversion section where the bypass passage diverges from the communication passage. A control member controls the diversion control valve in accordance with the operating state of the internal combustion engine.

Abstract: In an engine valve drive control device, a cam lobe is removably engaged with a cam shaft of a valve actuating line of an engine. The cam lobe is rotated, when engaged, together with the cam shaft to drive a valve. Free rotation of the disengaged cam lobe is halted by a cam rotation halting device to leave the valve inactive. The cam lobe is made axially slidable in the axial direction with respect to the cam shaft, and the engagement/disengagement of the cam lobe with/from the cam shaft are switched according to the sliding motion of the cam lobe.

The intake device comprises an air flow resistance adjusting mechanism for adjusting the air flow resistance in an intake passage in linkage with a variable intake pipe length mechanism to provide an excellent optimum air/fuel ratio over the entire speed range of the internal combustion engine. The variable intake pipe length mehcanism comprises a stationary intake pipe connected to a carburetor, a guide pipe separated from the stationary intake pipe, and a movable intake pipe slidably mounted on the guide pipe so tat the movable intake pipe is capable of coming in contact with or being spaced from the stationary intake pipe in response to the engine revolving speed. The movable intake pipe is connected to the stationary intake pipe below the predetermined engine speed and separated from it above the predetermined engine speed. The air flow resistance adjusting mechanism comprises a case adapted to enclose the stationary intake pipe, the movable intake pipe and the guide pipe, and having an intake passage communicating with the atmosphere and a mechanism for varying the air flow resistance of the intake passage in response to the switching motion of the movable intake pipe.
