摘要： Intake ports include a second port configured such that a flow rate of flowing gas is adjusted via a swirl control valve. When a surge tank is viewed in a cylinder axis direction, first and second branched passages are connected with a space being interposed therebetween in a cylinder array direction, and are connected to the surge tank on extension lines, each of which extends from an upstream end portion of an independent passage connected to the second port to an opposite side of each cylinder.

摘要： An intake device of an engine comprises an intercooler, an intake passage including a downstream-side intake passage, and an EGR passage recirculating exhaust gas to the downstream-side intake passage. An intake-air supply opening having an opening area smaller than an area of a downstream-side face of an intercooler core is provided at a downstream side wall of a chamber. The downstream-side intake passage includes an extension passage portion extending upwardly along the downstream side wall. The intake-air supply opening includes an upper edge portion which separates the intake air flowing from an inside wall face of the extension passage portion and forms flowing main streams of the intake air inside the extension passage portion. EGR introduction ports are arranged at positions capable of supplying the EGR gas toward the flowing main streams.

摘要： The present disclosure aims to improve circulation of intake air and distribution of bypass intake air to cylinders, while reducing an increase in the overall height of an engine. A supercharger extends along a cylinder bank at a side of a surge tank extending along the cylinder bank. A bypass pipe branching off from an upstream intake pipe configured to introduce the intake air into the supercharger extends along the cylinder bank above the supercharger. A downstream side intake pipe configured to guide the intake air from the supercharger to the surge tank extends downward from the supercharger. The downstream intake pipe is, in a U-shape as viewed along the cylinder bank, connected to the surge tank.

摘要： The present disclosure aims to stabilize, in an engine with a supercharger, a detection result of an intake air temperature sensor interposed between the supercharger and an intercooler. A gas outlet of a supercharger and a gas inlet of an intercooler are connected together via a second passage. The second passage includes, in its middle position, a narrow region with a smaller cross-sectional area than the part of the second passage extending from an upstream end of the second passage to the middle position. The narrow region is provided with the intake air temperature sensor configured to detect the gas temperature in the narrow region.

摘要： An exhaust device of a multi-cylinder engine which controls local introduction of exhaust gas to a catalyst device and a variation between cylinders of introduction positions of the exhaust gas to the catalyst device is provided. The exhaust device is arranged so that the cylinders extend in a vehicle width direction at a vehicle front part, and an exhaust line is arranged so as to extend rearward from a rear of the engine, wherein, in sequence from an upstream side of an exhaust gas flow, four independent exhaust pipes corresponding to the cylinders, collecting pipes which collect all independent exhaust pipes, and the catalyst device are provided. The single exhaust pipe includes two bending parts and a downstream part thereof is connected so that the exhaust gas is introduced from a direction that is diagonally lateral to an inlet part of the catalyst device.

摘要： An exhaust gas recirculation (EGR) passage is connected with an intake passage (a bypass passage bypassing a supercharger) of an engine. The EGR passage includes, in a position close to a connection port to the intake passage, an expanding portion in which a passage cross-sectional area expands and which lowers a flow speed of EGR gas so as to reduce an uneven flow, in the connection port, of the EGR gas flowing into the intake passage.

摘要： Provided is an exhaust device connected to an engine body. The exhaust device includes a plurality of independent exhaust pipes, each of which has a circular cross section, and which are connected to exhaust ports of cylinders of the engine body; and a mixing pipe having a circular cross section, connected to downstream ends of the independent exhaust pipes, and through which exhaust gas that has passed through the independent exhaust pipes flows in. The independent exhaust pipes are connected to an upstream end of the mixing pipe in such a manner that parts of internal spaces of the circular cross sections overlap each other in a predetermined section from the downstream ends of the independent exhaust pipes toward upstream, and a ratio of overlapping portions of the circular cross sections gradually increases from upstream toward downstream.

摘要： An intake passage of an engine includes a throttle valve, a supercharger, and a bypass passage connecting an upstream side with a downstream side of the supercharger and opening when the supercharger is not acting. When the supercharger is not acting, the intake passage generates forward flows in which intake air flows from the throttle valve toward the supercharger and bypass-directed flows in which the intake air is reversed due to blockage of forward movement by the supercharger and flows from the supercharger side toward a connection port, of the bypass passage, opening in the intake passage. An evaporated fuel introduction opening leading evaporated fuel produced in a fuel tank to the intake passage opens in a wall surface, on which the bypass-directed flow is generated, in the intake passage.
