摘要： A bypass passage for bypassing a check valve is connected with a vacuum introducing passage of a brake booster. The bypass passage is provided with a switching valve. Just before the start of an engine, the switching valve temporarily opens the bypass passage whereby to equalize a remaining pressure of the brake booster substantially becomes equal to an atmospheric level. As a result, the pressure in the brake booster at the starting time is set to substantially the atmospheric level so that the airflow to be sucked from the brake booster into the intake pipe at the starting time is made substantially contact every times. Thus, the fuel injection rate can be set considering the airflow to be sucked from the brake booster into the intake pipe at the starting time, even if that airflow cannot be detected.
摘要翻译：用于旁路止回阀的旁路通路与制动助力器的真空引入通道连接。旁通通道设有切换阀。在发动机起动之前，切换阀暂时打开旁路通道，从而使制动助力器的剩余压力基本上等于大气压。因此，制动助力器在起动时的压力被设定为大体上的大气压，使得在起动时从制动助力器吸入进气管的气流大致接触。因此，即使不能检测到气流，也可以考虑在起动时从制动助力器吸入进气管的气流来设定燃料喷射率。

摘要： An apparatus for controlling a flow of evaporated fuel from a canister being fed into an intake passage of an engine through a plurality of control valves arranged in parallel in a purge passage between the canister and the intake passage. The plurality of control valves includes at least a first valve being switched on and off by setting a control factor indicating a duty ratio of an on-time within a duty cycle to a total duty-cycle time for the first valve, and a second valve being switched on and off by setting a control factor indicating an on-state or off-state of the second valve for a total duty-cycle time. The apparatus includes a first control part for setting a first control factor for the first valve so that the first valve is switched on at a rate indicated by the first control factor, and a second control part for setting a second control factor for the second valve so that the second valve is switched on and off at a timing different from a timing at which the first valve is switched on and off.

摘要： Disclosed is a variable venturi type carburetor which is provided with a suction piston movable in a direction perpendicular to an air flow, in accordance with changes in the air flow, so as to vary the area of a venturi opening formed between the bottom end of the suction piston and a wall of the carburetor body facing the bottom end of the suction piston, for maintaining the speed of the air flow passing through the venturi opening substantially constant. The suction piston has a hole formed therein communicating the venturi opening with a suction chamber in which the suction piston is moved. The carburetor has a spring for urging the suction piston, but does not have any oil damper within the suction chamber. The shape of the venturi opening is so arranged that the increase of the area of the venturi opening in accordance with the displacement of the suction piston is gradually increased. As a result, fluctuation due to the resonance and wide fluctuation caused during the transient response of the suction piston do not occur.

摘要： A canister communicates with an intake manifold of an internal combustion engine through a purge pipe. The canister absorbs fuel vapor evaporated in a fuel tank. The absorbed fuel vapor is purged into the intake manifold when the engine is on. A gas leak check module communicates with the canister for drawing air by an air suction pump 43. When the engine is off, the air suction pump is driven and draws hydrocarbon floating at a vicinity of an intake port through the purge pipe. Thus, the hydrocarbon floating at the vicinity of the intake port is absorbed in the canister so that emission of hydrocarbon is reduced.
