    摘要: A cooling system of a cylinder liner of an internal combustion engine includes a plurality of first passages formed on an outer surface of the cylinder liner of the internal combustion engine and spaced apart from each other. A second passage is formed on the outer surface of the cylinder liner and runs in an axial direction of the cylinder liner, coupling the first passages to each other. The second passage receives, via an inflow part thereof, a coolant supplied in a traverse direction substantially perpendicular to the axial direction. A third passage is formed on the outer surface of the cylinder liner, and runs in the axial direction of the cylinder liner, coupling the first passages to each other. The third passage outputs the coolant received from the first passages to an outflow part thereof. The second passage has a traverse-sectional area which decreases as a distance of the traverse-sectional area from the inflow part increases. The third passage has a traverse-sectional area which decreases as a distance of the traverse-sectional area of the third passage from the outflow part increases.

    摘要: A cooling system of an internal combustion engine has a plurality of coolant passages located in a row along a longitudinal axial direction of a cylinder liner. Each of the plurality of coolant passages is located so as to extend approximately along a circumference of the cylinder liner. The plurality of coolant passages are located between an inner wall of a cylinder block and an outer wall of the cylinder liner. The cylinder liner is fitted in the cylinder block. The cooling system also has an inflow passage through which coolant flows into the plurality of coolant passages. The cooling system also contains a flux passage through which coolant flows out of the plurality of coolant passages. The inflow passage and the flux passage are arranged such that, the closer a coolant passage is to a combustion chamber end of the engine cylinder, the smaller the pressure loss of coolant flowing through a part of the inflow passage, that coolant passage and a part of the flux passage, the coolant traveling along that part of the inflow passage, that coolant passage and that part of the influx passage.

    摘要: In a driving force transmission mechanism using a timing belt for an internal combustion engine according to the present invention, a face width of teeth of the timing belt at dedendums of the teeth is set larger than a width of engagement of a tooth of the timing belt with a tooth of a timing pulley. In the mechanism, a certain degree of freedom in accordance with elastic deformation is given to the width end portions of teeth of the timing belt, and thereby concentration of a load can be decreased on a corner of the dedendum of the teeth. As a result, breakage of the fibers of a canvas and cracking of the teeth of the timing belt etc. can be prevented, and the durability and the span of life of the timing belt can be increased.

    摘要: A direct fuel injection-type spark-ignition internal combustion engine is disclosed. The engine comprises a spark plug, a cavity formed on the top surface of the piston, and a fuel injection valve for injecting fuel into the cavity in nearly the flat fan shape having a relatively small thickness. An opposing side wall of the cavity opposite to the fuel injection valve, for leading the fuel to the vicinity of the spark plug, has an arcuate portion having a plurality of arcuate shapes in a plan view. The radius of arcuate shape at the both side parts of the arcuate portion in a plan view is smaller than the radius of arcuate shape at the center part of the arcuate portion in a plan view. The opposing side wall has a deflecting portion to deflect the fuel toward the inside of the cavity.

    摘要: An engine compartment structure for introducing cool air into an air intake port without providing a baffle plate is constructed such that air discharged by cooling fans is directed away from the air intake port. A rotational direction of a second cooling fan of a pair of cooling fans can be opposite to the first cooling fan. The first cooling fan is closer to the air intake port than the second cooling fan. Air volume discharged by the first cooling fan can also be larger than that of the second cooling fan. Furthermore, rotational directions of the pair of cooling fans can be selected such that the air discharged by the cooling fans is directed toward a space at the rear side of the opposite headlamp, and each air volume discharged by the respective cooling fan set differently.
