Abstract
PURPOSE: To lower the fuel consumption of a four-cycle engine at the time of low- speed operation of the same, by letting the engine to suck air or lean mixture by use of the partial vacuum developed in a cylinder during the time period from the end of the intake stroke to the time when the compression stroke of the engine is started.
CONSTITUTION: A port 6 is formed in the side wall of a cylinder 5 of an internal combustion engine, and it is communicated to an air cleaner 1 via an automatic check valve 7. When the engine is operated at a low speed, a high intake vacuum is developed in the inner space 4 of the cylinder 5 due to pressure loss by the restriction of a carburetor 2. Here, the automatic check valve 7 is designed to be opened by the intake vacuum developed in the cylinder for drawing air or lean mixture from air cleaner 1 directly into the cylinder in the manner of by-passing the carburetor 2. With such an arrangement, it is enabled to lower the fuel consumption at the time of low-speed operation of the engine.
