    摘要： Supply of supplementary fuel is controlled by activation of a valve in response to certain engine operating conditions or parameters. For example, the supplementary fuel may be supplied to facilitate starting and warming up a cold engine, or to cool and/or slow down an engine operating above a threshold speed.

    摘要： Apparatus and method for reducing pollutant emissions by improving fuel atomization and optimizing air-fuel ratio in the carburetion of internal combustion engines. A small stream of bleed air is mixed with the fuel after it has passed through the fuel metering restriction but before atomization thereof, and then this mixture of fuel and bleed air is passed through the atomizing orifice. The atomizing velocity is thereby increased, causing improved atomization and hence better combustion of the mixture, resulting in less pollutant emissions. By providing the bleed air from a source wherein the pressure is generally inversely related to the rate of fuel flow, a relatively large amount of bleed air is made available to thus improve combustion at low speed operating conditions when hydrocarbon emissions tend to be excessive, while accommodating greater fuel flow as required during high speed operating modes when atomization is normally good. Modulation of this bleed air flow provides an effective means for adjusting the air-fuel ratio output of the carburetor. Thus, in one form of the invention temperatureresponsive bleed air modulation provides self-adjustment to compensate for the natural tendency of a carburetor to richen the mixture as its ambient temperature increases. In another form of the invention the air-fuel ratio is automatically adjusted to compensate for air-fuel ratio deviations from the desired average by sensing the air-fuel ratio and modulating the bleed air flow in response thereto.

    摘要翻译： 通过改善燃油雾化和优化内燃机化油中的空燃比来减少污染物排放的装置和方法。 一小部分排出的空气在燃料通过燃料计量限制之后但是在雾化之前与燃料混合，然后燃料和排放空气的混合物通过雾化孔。 因此雾化速度增加，导致混合物的雾化改善并因此更好地燃烧，导致较少的污染物排放。 通过提供来自源的排出空气，其中压力通常与燃料流量的速率成反比，可以获得相对大量的排放空气，从而在碳氢化合物排放趋于过度的同时在低速运行条件下改善燃烧，同时 当雾化通常良好时，可以在高速运行模式下满足更大的燃料流量。 这种排放气流的调节为调节化油器的空燃比输出提供了有效的手段。 因此，在本发明的一种形式中，温度响应性泄放空气调节提供自调节以补偿化油器随着环境温度升高而使混合物的自然趋势。 在本发明的另一种形式中，空燃比被自动调节，以通过检测空燃比并响应于此调节排气流量来补偿与期望平均值的空燃比偏差。

    摘要： An engine-driven working machine includes a controller, which varies a control value of a solenoid valve so as to decrease or increase an opening degree of the solenoid valve when a rotating speed of an engine is within a predetermined high rotating speed range and the rotating speed of the engine is lower or higher than a predetermined rotating speed, respectively. In case the controller determines that the engine-driven working machine gets started saw cutting, the controller stops varying the control value of the solenoid valve when the rotating speed of the engine is within the predetermined high rotating speed range and lower than the target rotating speed.

    摘要： A carburetor with a single fuel system that is capable of ensuring stable engine operation and lower fuel consumption. The fuel system comprises an electrical fuel control C that, in addition to mechanically coordinating the fuel flow rate with air intake by way of a metering needle 22 that operates in coordination with the throttle valve 3, opens and closes opening/closing valve 30 and cuts off and delivers fuel to the air intake passage 2 so as to maintain a required target rotational speed with little fuel consumption in a specific region of the degrees of opening of the throttle valve 3. Stable operation with minimal fluctuations in the rotational speed is ensured by cutting off the fuel when the rotational speed rises above the target rotational speed, and delivering the fuel when the rotational speed falls below the target rotational speed.
