现代农业需要现代的农业机械,现代农业机械往往以柴油内燃机为动力,驱动各种自动化、半自动化机械作业。在这些以内燃机为动力的车辆中少不了燃油系统的配置。因农业机械车辆往往是低速机械车辆,传统的燃油供给系统为机械油泵和手动泵。而机械油泵的供油量大小又几乎正比于车辆的转速,所以原供油系统对于车辆低速条件下的作业,就显得动力不足,机械作业不可靠,启动速度慢,特别是冷启动,常常还有小马拉大年的感觉。现在由上海交大科研人员研制,上海广垠交通 Modern agriculture requires modern agricultural machinery. Modern agricultural machinery, often powered by diesel internal combustion engines, drives a variety of automated and semi-automated machinery operations. In these internal combustion engine powered vehicles, ultimately, the fuel system configuration. Because agricultural machinery vehicles are often low-speed mechanical vehicles, the traditional fuel supply system is a mechanical oil pump and a hand pump. However, the amount of oil supplied by the mechanical oil pump is almost proportional to the speed of the vehicle. Therefore, the original oil supply system appears to be lack of motivation for low-speed operation of the vehicle, unreliable mechanical work, slow start-up, especially cold start and often Have the feeling of a small horse pull the New Year.
