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.

A heat insulating structure of an internal combustion engine (engine) includes a cylinder-head-side heat insulating cover () and a cylinder-block-side heat insulating cover (). Each of the first side walls () of the cylinder-head-side heat insulating cover () is disposed outwardly of, and is spaced apart from, a corresponding one of the second side walls () of the cylinder-block-side heat insulating cover () in the width direction of the vehicle. The lower edge of each of the first side walls () is positioned below the upper edge of the corresponding one of the second side walls () to overlap with the corresponding one of the second side walls () when viewed from the side of the vehicle.

An air intake apparatus of a multi-cylinder engine includes an intake air inlet passage, an intake air distribution portion, a plurality of independent intake air passages, and a secondary gas inlet passage. The intake air inlet passage has one end portion attached to a throttle valve, and the other end connected to an intake air distribution portion. The intake air distribution portion has a space therein. The secondary gas inlet passage is connected at a part spaced apart, in the intake air inlet passage, from the throttle valve. The intake air distribution portion has a reflux passage which is a passage that connects the space and a part between the one end portion and the other end in the intake air inlet passage. The reflux passage is a passage which refluxes fresh air and secondary gas introduced from the intake air inlet passage to the intake air inlet passage.

A heat insulating cover (cylinder-head-side heat insulating cover ()) includes a top wall () and first side walls (). The top wall () covers a top surface of an engine () that is a surface of an upper portion of the engine (). The first side walls () cover respective upper portions of both side surfaces of the engine () in a vehicle width direction. A portion of the heat insulating cover closer to the rear of the vehicle is provided with a hinge mechanism () vertically rotatably supporting the upper portion of the heat insulating cover including the top wall (). The upper portion of the heat insulating cover can be rotated, with the hinge mechanism () as a fulcrum, between a closed position where the engine () is shielded and an open position where the engine () is visible.

An exhaust purification device of a multi-cylinder engine which improves exhaust gas purification performance by substantially uniforming a flow rate of exhaust gas throughout a treatment carrier such as a catalyst and improving dispersibility of the exhaust gas from the multi-cylinder engine to the catalyst and other components in the exhaust purification device wherein two collecting pipes are arranged at substantially symmetric positions across a partition plate part, which has a linear cross sectional shape, and is arranged centrally between the pipes which are each formed into D-shaped cross sectional shapes and comprise a first straight line part, a pair of second straight line parts connected with respective ends of a first straight line part and arranged to be substantially parallel with each other, and a circular arc part that connects ends of a pair of second straight line parts on opposite sides of the first straight line part.

A heat fumigation apparatus for transpiring a solution of a chemical agent dissolved in a solvent by heating which comprises a container having the solution therein, a wick a part of which is immersed in the solution and a heater for heating the upper portion of the wick thereby transpiring the solution drawn up the wick. The wick is composed of an inorganic powder and/or an organic powder, a binding agent and at least one antioxidant which is substantially non-evaporative at a heating temperature.
