An engine including a silencer in the exhaust passage thereof, wherein an exhaust gas flow passage pipe is arranged in the silencer body and a particulate filter is arranged inside the exhaust gas flow passage pipe. A first exhaust gas inflow-outflow opening and a second exhaust gas inflow-outflow opening of the exhaust gas passage pipe and an exhaust gas inflow opening to the silencer body are arranged at one end of the silencer body. The exhaust gas is selectively supplied to the first exhaust gas inflow-outflow opening, second exhaust gas inflow-outflow opening, and exhaust gas inflowing opening.

Exhaust device of internal combustion engine

An HC (hydrocarbon) supplementing device is mounted in an exhaust purification device of an internal combustion engine, wherein the amount of HC in the fuel to be added is automatically adjusted to a degree corresponding to the operating conditions of the engine. Accordingly, the supply of just enough HC becomes possible without the use of a complex mechanism for adjusting the supply of HC, and the exhaust gas can be sufficiently purified without wasting fuel.

Exhaust purification apparatus

A helically-shaped intake port comprising a helical portion formed around an intake valve, and a substantially straight inlet passage portion tangentially connected to the helical portion. A bypass passage is branched off from the inlet passage portion and connected to the helical portion. A slide valve is arranged in the bypass passage and controlled by a stepper motor so that the opening area of the slide valve changes in proportion to the amount of air to be fed into the cylinder of the engine.
