摘要： PURPOSE: To prevent burning of engine by providing a valve mechanism to be opened/closed with pressurized engine oil at the output of pump at the fuel inlet path of fuel injection pump thereby stopping fuel supply quickly with correspondence to insufficient engine oil supply.
CONSTITUTION: A plunger type valve 14 is fitted slidably in a banjo bolt 13 for fixing a banjo 12 to the pump body while a valve hole 15 is communicated into the banjo 12. While T-type valve path 16 is provided in the valve 14 and a spring 17 will energize to full-close side. The oil chamber 19 of diaphragm chamber 18 fixed to the end of bolt 13 is communicated to the delivery of an engine oil supply pump while the diaphragm 20 is communication with the valve 14. Upon insufficient oil supply to engine, pressure oil supply to oil chamber 19 is reduced to return the diaphragm 20 through the spring 17 thus to interrupt communication between the valve path 16 and the valve hole 15 through the valve 14.

摘要： PURPOSE:To stop certainly any reverse turn of an engine by providing, on the release cam of a release lever for reverse turn stopping, a cam lobe which turns in a direction reverse to that of a cam shaft at the time of its reverse turn and projects from a cam base. CONSTITUTION:The fly weight 13c of a release cam leb provided on a release lever 13 for reverse turn stopping during the initial phase of reverse turn of an engine is subjected to the energizing power of a return spring 14 so as to be locked in its closed angle state in the turning direction reverse to that of a cam shaft 2 for making reverse turn. Thereby, an intake tappet 8b runs over the cam lobe 13e of the release cam 13b so as to be lifted up forcedly, and then an intake valve provided aside on the intake tappet 8b is opened in a compression stroke. Compression pressure is thus reduced, and the engine is stopped immediately before attaining an ignition temperature so that it may be prevented automatically from making a reverse turn.

摘要： PURPOSE:To reduce piston slap noise of an engine, by forming annular grooves on both edges of an oil scraping ring groove and also forming an oil induction concave from the grooves to piston edge. CONSTITUTION:Annular grooves 12a, 12b, with a diameter smaller than the maximum diameter of piston profile, are formed on upper and lower edges of a piston ring groove 12 to which an oil scraping ring 11 is fitted at the center of a skirt 4a of the piston 4. Lubricating oil scraped off by the ring 11 is evenly induced to the piston radially. An oil induction concave 13, communicated with the groove 12 and reaching the piston edge 4b, is formed on the lower side below the ring 11, so that lubricating oil on the wall of a cylinder 3 is not scraped off by the piston edge 4b.

摘要： PURPOSE: To eliminate the occurrence of a risk due to reversing phenomenon during the starting, by a method wherein, when the number of cranking revolutions exceeds a reversing generation range, release from decomp is effected.
CONSTITUTION: A pin 15 of a weight lever 13, pivotally secured at 14 to a cam gear 6, is engaged with an engaging part 11 of a decomp pin 9, and a forward pin 12 of the decomp 9 is positioned in the compression stroke of a cam 4. The forward end 12 of the decomp pin 9 is emerged from a cam 4, decomp of an engine is effected in the whole area or the partial area of a compressivion stroke, or a partial area extending over the whole area or the partial area of the compression stroke and an expansion stroke. The number of revolutions, by means of which release from decomp is effected, is set to an area of the number of revolutions higher than that in the reversing generation area of an engine, and this eliminates a troublesome preparatory work before the starting of an engine, enables reduction of an operating force during the starting of an engine, and ena bles prevention of the occurrence of a risk due to reversing.

摘要： PURPOSE:To reduce the noises of the connected part, by interposing a collar between the major end of the connecting rod and a cran arm and pushing the collar by a push means to restrict the motion of the major end. CONSTITUTION:Hydraulic force is applied to the collar 20 through a lubrication oil passage 17, an oil groove 18 and a lubricating oil passage 21 by the oil supply action of an oil pump when the engine is operating. The collar 20 is pushed by the hydraulic force from one side of the major end 7 of the connecting rod 6 to the inside surface of the crank arm 16 facing the side of the major end 7. As a result, the motion of the major end 7 in the axial direction of the crank pin is restricted. Thereby the major end is kept from hitting the inside surface of the crank arm 16.
