Abstract: 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.

Abstract: 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.

Abstract: 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.

A pair of facing surfaces which face each other with a space are provided at the EGR system attached to the intake manifold and the intake manifold. A damper plate having elasticity is arranged between these facing surfaces. The damper plate is configured to have a larger thickness than the above-described space and have a smaller Young's modulus than each of a lower-side facing-surface portion and an upper-side facing-surface portion, and the damper plate is clamped between the lower-side facing-surface portion and the upper-side facing-surface portion.

The gas-injected bubble water generated from the nanobubble generation device is pressure-fed to the nozzle outer cylinder of the two-fluid nozzle, and compressed air from the compressor is pressure-fed to the air connection tube of the two-fluid nozzle. In the two-fluid nozzle, the high-pressure gas-injected bubble water and the compressed air serve as a gas-liquid fluid mixture, and are injected at a high speed in mist form from a nozzle cylinder of the two-fluid nozzle.

The downstream intake pipe is, in a U-shape as viewed along the cylinder bank, connected to the surge tank.
