摘要： An intake system for a horizontally opposed type internal combustion engine can contribute to an improvement in output performance without sacrificing the intrinsic merit of the horizontally opposed type internal combustion engine. Specifically, the intake system ensures that the overall height of the engine remains small. First and second intake ports are provided at head portions of first and second banks, which are arranged on the left and right sides. First and second intake distribution ports are arranged horizontally at a front wall of an intake surge tank 10, which is disposed on the rear end side of and adjacent to a crankshaft 1. The first and second intake ports are respectively connected with each other through first and second intake pipes disposed along a top surface or bottom surface of the engine E. Throttle valves for controlling intake quantities in the first and second intake pipes are provided in upstream portions of the intake pipes.

摘要： A multi-layered plastic pipe particularly suitable for use as an intake manifold of an internal combustion engine is provided. The present pipe includes a hollow plastic core, at least one spacer member provided on the hollow plastic core and an outer layer integrally provided on the outer peripheral surface of the hollow plastic core excepting the spacer member. The spacer member is preferably formed from a plastic material, and the outer layer is also formed from a plastic material. There is also provided a method for manufacturing a multi-layered plastic pipe using a spacer member to prevent a hollow plastic core placed in a mold cavity from being deformed when a molted plastic material is supplied into the mold cavity under pressure.

摘要： A water circulation system of a marine engine improves the consistency of engine combustion by stabilizing the temperature of water flowing through the engine water jacket and by heating the intake manifold to a temperature within a desired temperature range. The desired temperature range is defined so as to optimize fuel vaporization without significantly affecting the volumetric efficiency of the engine. The water circulation system includes a control valve which directs water flow through the circulation system according to the water temperature exiting the engine water jacket. The valve recirculates water between the engine water jacket and a recirculation path until the water temperature reaches a predetermined lower temperature limit. The control valve then allows a portion of the water to flow through a heating jacket around the intake manifold to heat the intake manifold. If the temperature of the recirculating water reaches a predetermined upper temperature limit, the control valve directs all of the water through the heating jacket until the temperature of the water exiting the engine water jacket falls below the upper temperature limit. In this manner, the water circulation system generally stabilizes the water temperature in the engine water jacket and heats the intake manifold to a temperature generally within the upper and lower temperature limits.

摘要： A V-engine for permitting the engine to be more compact and easy to assemble and to improve engine cooling performance. In a first embodiment, the branch pipes of the intake manifold of the engine extend at an acute inclined angle with respect to the centerline of the crankshaft. This inclined arrangement provides a space through which the cooling water intake pipe and the cooling water discharging pipe can extend. In a second embodiment, the surge tanks of the intake manifold are longitudinally offset to provide spaces in which the thermohousing of the thermostat mounted on the cooling water intake pipe and the cooling water discharging pipe can be mounted. In a third embodiment the axis of an auxiliary machine, such as a generator, is laterally offset from the centerline of the engine crankshaft to provide a gap and the cooling water pipe extends through the gap.

摘要： A fuel intake system for a combustion engine of a type having V-shaped first and second cylinder banks and also having a crank axis of the crankshaft, which comprises a throttle casing disposed in a center space delimited between the first and second cylinder banks, elongated first and second surge tanks extending in a direction parallel to the crank axis and disposed on respective sides of the center space, and a passage system communicating the throttle casing to each of the first and second surge tanks. The passage system comprises a merging region communicated with the throttle casing and first and second branch ducts branched off from one end of the merging region opposite to the throttle casing. The first and second branch ducts connect to the first and second surge tanks, respectively. Each of the first and second branch ducts is comprised of two independent passages spaced apart from each other in a direction parallel to the crank axis. These two independent passages of each of the first and second branch ducts are communicated with different portions of the associated surge tank which are uniformly spaced from each other in a direction parallel to the crank axis.

The manifold is made of an aluminum plenum chamber having an air inlet and a plurality of air outlets with a plurality of wrought aluminum branch pipes extending from the respective plenum outlets. The branch pipes have an inner peripheral surface of circular cross section. At least one of the branch pipes is deformed at an intermediate portion along its length thereby forming a clearance area so that the branch pipe is free from contact with the adjacent branch pipe.
