摘要： PURPOSE:To secure a sufficient compression ratio, by installing a cylinder part to be interconnected to a combustion chamber, in a cylinder head, and controlling the piston fitted slidably in this cylinder part so as to make the combustion chamber capacity smaller at the time of low load. CONSTITUTION:A cylinder part 21 to be interconnected to a combustion chamber 13 is installed in a cylinder head 5, and a piston 22 is slidably fitted in this cylinder part. The piston 22 is driven by feed or discharge of pressure oil for pressure starting chambers 25 and 26 at the upper part. And, engine load is detected, whereby the piston 22 is driven upward so as to make combustion chamber capacity inside the cylinder part 21 larger in a high load manner, but in a low load manner, the piston 22 is driven downward so as to make this combustion chamber capacity smaller. With this constitution, combustion of an air-fuel mixture is favorably performable without entailing any drop in an effective compression ratio even at the time of low load.

摘要： PURPOSE:To reduce the trapping of gas by increasing the flow rate of mixed gas in medium and low speed regions by providing a negative pressure responding part whose top portion is positioned in a suction pathway to the wall of a suction pipe on the downstream side of a throttle valve. CONSTITUTION:On the upper wall portion positioned nearly the center of a suction pipe 3, a negative pressure responding valve 5 is provided in such a way that its top portion 5a is positioned in a suction pathway 4. In a low-speed roration region or partially negative condition where a throttle valve 2 is closed, a difference in suction negative pressures is produced between the upstream and downstream sides of the throttle valve 2 in the suction pathway 4 according to the degree of opening of the throttle valve 2, whereupon according to the difference in the negative pressures, the top portion 5a of the negative pressure responding valve is projected into the suction pathway 4. Thus, the cross section and volume of the suction pathway which are adaptable to the low-speed rotation region or partially negative condition can be obtained.

摘要： PURPOSE:To maintain enhanced power output in a device, in which the secondary air is injected in cylinders at a point near the lower dead point of piston, by lessening the amount of counterflow of combustion gas into the secondary air intake port. CONSTITUTION:A secondary air intake port 19 is furnished in each cylinder 2 of an engine 1 at a location near the lower dead point of piston 3. Discharge hole 16 of an air pump 14 is connected with the secondary air intake port 19 through a secondary air introducing passage 17, and a one-way valve 20 is installed in each of divergent passages 18 for said secondary air introducing passage 17. Here the secondary air intake port 19 begins opening when the intake stroke is situated 2beta deg. before ending (beta deg. from the lower dead point) and is shut when or before the suction valve is closed, so that the air pressurized by a vane type air pump 14 during this period is introduced through the secondary air introducing passage 17, divergent passages 18, one-way valve 20 and intake port 19 to give an enhancement of the filling efficiency.

摘要： PURPOSE:To regulate fuel supply according to an amount of secondary air by introducing into the float chamber of a carburetor, the pressure corresponding to the secondary air pressure introduced through an inlet opened and closed by a piston. CONSTITUTION:A pressure leading passage 2 is branched from a surging chamber 16 in a secondary air introduction passage 4, while said passage 2 is opened to the float chamber 12a of a carburetor through a pressure reduction device 23. A fuel control device is so constructed that the pressure, corresponding to the secondary air pressure introduced through a secondary air inlet 3, is introduced in to said float chamber 12a. Thus, since the fuel in said float chamber 12a is subjected to the pressure in said surging chamber 16, that is, the pressure corresponding to the secondary air pressure introduced through a pump 5, the amount of the fuel led to a cylindr 1 is increased in response to said pressure.
