如今不少机手为了多拉快跑赚大饯,拖拉机长时间超负荷工作,殊不知这是得不偿失的。当拖拉机短时间超负荷时(如遇到爬坡或道路泥泞阻力增大时),在发动机校正器作用下,可适应负荷的变化而增加供油量,使发动机的扭拒增大,克服暂时增大了的阻力。但是,拖拉机不允许长时间在超负荷下工作,如长期超规定吨位拉运,将使发动机工作强度加大,零件承受过大机械负荷和热负荷,使磨损加剧,并容易损坏;同时供油量增大到冒烟界限油 Nowadays, quite a few hand-drivers have been working hard to make Dora run fast and their tractors have been overloaded for a long time. Everybody knows that this is not worth the candle. When the tractor overload for a short time (such as climbing or road muddy resistance increases), under the action of the engine corrector to adapt to changes in load and increase the amount of fuel supply, so that the torsion of the engine increases, to overcome the temporary Increased resistance. However, the tractor does not allow a long time to work under overload, such as long-term ultra-tonnage of tonnage will make the engine work intensity increases, the parts are subject to excessive mechanical and thermal loads, aggravating the wear and tear, and easy to damage; Increase the amount of smoke to limit the oil
