摘要： PROBLEM TO BE SOLVED: To provide an engine capable of securing appropriate cooling effect at each section of an engine using fuel as lubricating oil.
SOLUTION: The engine 1 pumps up gas oil which is fuel also used as lubricating oil from an oil pan 3 and jets the same on a piston back side 20a from an oil jet 28. Gas oil jetted on the piston back side 20 evaporates in a space part 27 surrounded by a cylinder liner 22, the piston 20 and the oil pan 3 and decompressed by a decompression pump 30, and takes heat out from the piston 20 by endothermic reaction thereof. Consequently the piston 20 is cooled.

摘要： PROBLEM TO BE SOLVED: To provide a fuel supply control device capable of supplying fuel to an injection system immediately after fueling. SOLUTION: A fuel supply control device 20 is provided with a fuel lid open close sensor 17, an oil pan level sensor 18 and ECU 19. The ECU 19 determines whether fueling action is completed or not based on information from the fuel lid open-close sensor 17. When the ECU determines that fueling action is completed, the ECU determines whether fuel quantity in an oil pan 3 is less than a lower limit level or not based on data from the oil pan level sensor 18. When fuel quantity is less than the lower limit level, a drive command is issued to an electric supply pump 6 to supply oil to the oil pan 3 to enable to supply fuel to the injection system 12 from the oil pan 3 even right after fueling.

摘要： PURPOSE:To reduce the loss of power and to improve a lubricating effect, by a method wherein, through utilization of a difference between negative pressures at the upper part of a surface level of oil and in the oil in a crank chamber, produced as a result of reciprocating movement of a piston, and a centrifugal force, lubrication is practicable as the oil is pumped up. CONSTITUTION:When a crank shaft 3 is rotated through the medium of a connecting rod 7 as a result of reciprocating movement of a piston 9, at position where the piston 9 reaches an upper limit, an oil passage 13, formed in a crank pin 6, is communicated with a timing hole 14 provided in a large end part 7a of the connecting rod, and a high negative pressure, produced by a pulsating pressure in a crank chamber 2, is exerted on the outlet of the hole 14. The crank pin 6 and the large end part 7a of the connecting rod, in which said passage 13 and the hole 14 are provided, are rotated at a high speed at position which is located eccentrically from the center of the crank shaft 3, and thereby, a suction function, caused by a high centrifugal force, is exerted. As a result, the oil in the base of a crank case 1 is pumped up through said passage 13 and the hole 14 to perform lubrication of a bearing 4 and sliding parts 6a and 7a.
