    Abstract: PURPOSE: To constitute a wet cylinder liner so that deformation of the cylinder liner and a hole of a cylinder block through which the cylinder liner is to be inserted may be restrained to the minimum extent and so that deformation may be generated on the other part not hardly causing harm. CONSTITUTION: A contact area 60 of between a bearing protrusion 44 provided on a cylinder block hole wall and a supporting protrusion 46 provided on the outer periphery of a cylinder liner is provided in the dead bottom center of a lower gas sealing piston ring 38, a cylinder liner 12 has the upper part surrounded with at least one cooling medium passages 50 or 52, and the cylinder liner 12 is also surrounded with an air cooling medium space 56 extending downward to the contact area 60 independently of the passages.

    Abstract: PURPOSE: To remove an attachment existing at a spark plug by burning and improve a starting ability by generating a series of spark close to the spark plug in a state that an engine is difficult to start. CONSTITUTION: When a detective circuit 5 detects a difficult engine starting state by an engine parameter which is sensed at lines 8, 8', 8", a signal is sent from a line 6 to a control unit 3, then a spark cleaning process is started. And a series of control signals in a close state opens a transistor 30 of a charging circuit at a line 46 by the control unit 3 and discharging circuits 25, 26 are formed by sending the control signals from lines 44, 45 to triacs 23, 24. Consequently, the attachment is removed by burning by discharging all energy which are stored in an ignition capacitor 20 to the spark plugs 11, 13 at the same time. Thereby, the spark plugs 11, 13 can be conditioned satisfactory for a next attempt of starting.

    Abstract: PURPOSE: To provide a simple means of reconditioning a lubricant oil of a gear without need for a large-scale and expensive modification of the gear. CONSTITUTION: This device for reconditioning a lubricant oil of a gear which is desirous to serve as a central gear of a vehicle is mounted with a gear housing 12 partially filled with the lubricant oil and at least one of an external lubricant oil reconditioning device 30 which is desirous to serve as an oil filter. The reconditioning device 30, fixed to the gear housing 12, is formed such that the lubricant oil can be conveyed from the gear housing 12 to the external device 30 by a duct 40 including an inlet near a gear 22. An outlet duct 50 is formed such that the lubricant oil can be sent back to the gear housing. Energy necessary to convey the lubricant oil is obtained from the kinetic energy of the gear 22.
