多年来,我国手扶拖拉机用的单缸柴油机不安装油量校正器,由于用户往往超载超速行驶,使柴油机油泵拨叉移向最大油量位置,柴油机功率、扭矩急剧增加,燃油消耗率、排温、烟度等指标变坏。柴油机经常处于冒烟极限下工作,噪声提高,柴油机热负荷、机械负荷很大。长期在双重高负荷下工作,必然导致柴油机早期磨损、寿命缩短。为此,加装油量校正器,以限制无节制加大供油量来克服超负荷的工作势在必行。
Over the years, China’s single-cylinder tractor with a single-cylinder diesel engine does not install the fuel corrector, the user often overloaded speeding, the diesel pump shift fork to the maximum fuel position, diesel power, torque increased dramatically, fuel consumption, Temperature, smoke and other indicators worse. Diesel engines often work under the smoke limit, noise, diesel engine heat load, mechanical load is large. Long-term work under double high load, will inevitably lead to early wear and tear of diesel engine, shortened life expectancy. To this end, the installation of fuel corrector to limit the uncontrolled increase of fuel supply to overcome the overload of work is imperative.
