Abstract: A carburetor electronic control system includes: transmission devices coupled to valves for opening and closing an intake path of a carburetor; electric motors that make the valves open and close via the transmission devices; and an electronic control unit for controlling the operation of the electric motors. The interior of a casing joined to one side face of the carburetor is divided by a partition plate into a transmission chamber on the carburetor side and a drive chamber on the opposite side. The transmission devices and the electric motors are housed and held in the transmission chamber and the drive chamber, respectively. Therefore, the transmission devices, the electric actuators, and the electronic control unit can be housed in a common casing, thereby reducing the dimensions of the carburetor electronic control system.

Abstract: In an exhaust emission control system for an internal combustion engine, an exhaust gas recirculation device that operates so as to partially open an exhaust valve to introduce exhaust gas into a cylinder in an intake stroke is provided; a secondary air passage capable of supplying secondary air to an exhaust passage is connected to the exhaust passage; and a one-way valve opened by negative pressure applied from the cylinder to the exhaust passage following an operation of the exhaust gas recirculation device in the intake stroke is provided in the secondary air passage. Accordingly, it is possible to provide an exhaust emission control system for an internal combustion engine that allows secondary air to be supplied into an exhaust passage to reduce HC and CO concentrations and also a NOx concentration in an exhaust gas without using an air pump regardless of an exhaust system structure of the internal combustion engine.
