降低发动机的耗油率是设计者、使用者所一直追求的要求。为降低已设计好并在使用中的发动机的耗油率, 经过大量试验研究, 创制了一种装在M-11发动机上的节约燃油的节油器——称为M-11发动机节油器。M-11发动机节油器是一种具有涡旋发生器头部及可以开关的风门的节油装置,它装在汽化器后面,插入到发动机环形进气机匣中。可动的风门位置与发动机的油门位置是协调的 (用操纵机构保证), 以保证在各转速下既能节油,又能保证发动机所需的混合气量。M-11发动机节油器在中转速节油效果最好, 约为15～25%, 高转速时则较低, 为5～15%, 在1800转/分附近时稍有赔油现象。装节油器后, 使发动机最大转速降低20转/分, 缸头温度与排气温度均有所降低, 在试车台及飞行试验中, 表明节油器的节油效果是稳定的, 且它对飞机的操纵性能无影响。M-11发动机节油器是通过涡旋发生器对混合气进一步进行雾化与掺合,改善燃烧条件,使发动机能充分利用进入到气缸内的燃油而达到降低耗油率的。类似M-11发动机节油器的节油装置, 可以在装有汽化器的航空活塞式发动机上采用。
Reduce the engine’s fuel consumption is the designer, the user has been pursuing the requirements. In order to reduce the fuel consumption of a designed and in-service engine, a large number of pilot studies have led to the creation of a fuel economy economizer mounted on the M-11 engine called the M-11 engine economizer . The M-11 engine fuel economy is a fuel-saving device with a vortex generator head and a switchable damper that fits behind the carburetor and into the engine’s annular air intake case. The position of the movable damper is coordinated with the throttle position of the engine (guaranteed by the operating mechanism) to ensure fuel economy at each speed and to ensure the required amount of air-fuel mixture in the engine. M-11 engine fuel economy at the speed of the best fuel-efficient, about 15 ~ 25%, high speed is lower, for 5 to 15%, 1800 rev / min when a slight loss of oil phenomenon. Install the fuel economy, the engine speed to reduce the maximum 20 rev / min, the cylinder head temperature and exhaust temperature are reduced in the test bench and flight tests, show that economizer fuel economy is stable, and it No effect on the handling of the aircraft. M-11 engine fuel economy is through vortex generator for further atomization and blending of the mixture to improve combustion conditions, so that the engine can take full advantage of the fuel into the cylinder to achieve lower fuel consumption. Fuel-saving devices like the M-11 engine economizer can be used on an aero-piston engine equipped with a carburetor.
