    摘要： The cylinder head includes: an intake port; a low-temperature cooling water channel for circulating low-temperature cooling water; a high-temperature cooling water channel for circulating cooling water of a higher temperature than the cooling water flowing through the low-temperature cooling water channel; and a gas channel for recirculating a portion of blow-by gas or EGR gas to the intake port. The low-temperature cooling water channel is configured to include a first water jacket that covers at least one portion of the wall surface of the intake port on an intake-air upstream side relative to an opening end opening at a wall surface of the intake port from the gas channel.

    摘要： Charge air coolers (CACs) are commonly used in pressure-charged, internal combustion engines to reduce the temperature of the air entering the combustion chamber. Typically, one CAC is provided and all of the intake air is inducted past the one CAC. An intake manifold in which a plurality of CACs are provided in the intake runners, i.e., a parallel flow arrangement, is disclosed herein. By positioning the CACs in the intake runners, the CACs are more effective than when they are positioned upstream in the plenum. In some embodiments, the coolant is supplied and returned to the multiple CACs via headers. By providing coolant to each CAC that is substantially the same temperature, the cylinder-to-cylinder temperature variation is reduced compared to a single CAC.

    摘要： Even in the case where a crankshaft extends in a substantially vertical direction, it is possible to reduce a situation that sprays of fuel injected from injectors may adhere to inner wall surfaces of intake passages, and it is possible to make the fuel supply to combustion chambers stable. Provided is a vertical engine including: a pair of intake passages (911a and 911b) which are arranged in an up and down direction with the interposition of a central axis of a cylinder (241) therebetween; a pair of intake valves (41L1 and 41L2) which open and close the pair of intake passages; and fuel injectors (70L1 and 70L2) which inject fuel to the pair of intake passages; wherein: the fuel injectors are arranged so that fuel injection directions by the fuel injectors can go not toward valve stems (411) of the intake valves provided in the upper and lower intake passages respectively but toward the backs of valve heads of the intake valves on a central axis (C1) side of the cylinder and the fuel injectors are disposed so that a central axis (FC2) of injection of the fuel injector into the lower intake passage can be closer to the central axis side of the cylinder than a central axis (CF1) of injection of the fuel injector into the upper intake passage.

    摘要： An intake system of an engine includes an engine and an intake manifold. The intake manifold defines individual intake air passageways each connecting one of cylinders to a volume chamber. Each of the individual intake passageways includes a first route and a second route. The first route has a natural frequency, of an air column, synchronized with a first revolution higher than an engine revolution for maximum torque such that a dynamic supercharging effect is obtained at the first revolution. The second route has a natural frequency, of an air column, synchronized with a second revolution higher than the engine revolution for maximum torque such that a dynamic supercharging effect is obtained at the second revolution. The second revolution differs from the first revolution. A difference between the first and second revolutions is set lower than or equal to 15% of a maximum engine revolution.

    摘要： An intake manifold is equipped with a sub-stream passage connected to branch passages through respective connection ports to introduce intake-air substream other than intake-air mainstream to the plural branch passages. Two of the branch passages which communicate with each other through the sub-stream passage and successively introduce intake air to the internal combustion engine are defined as a first combination. Of the first combinations, a second combination is defined to have a shortest communication length via the sub-stream passage. Of the second combination, the connection port of one of the branch passages where the intake air is introduced later is narrower than that of the other of the branch passages where the intake air is introduced earlier.
