Ⅰ号泵广泛与缸径75～105毫米的高速柴油机匹配,使用范围面广量大,年产5万台,全国保有量达150万台。目前Ⅰ号泵与柴油汽车也大量匹配。驾驶员控制油门时,发动机转速也应立即随之相应改变。要求反应及时,一般应在1秒钟左右。若超过该值,油门即有滞后现象。如果加速降速不够及时,操作性能恶化,驾驶安全系数下降,则机车在爬坡换档需踩两脚离合器加速时,或车辆进入村庄、弯道需减速时都会给驾驶员带来许多不便。多缸Ⅰ号泵油门滞后,总的来说都是油门拉杆移动滞后所致,而油门
Ⅰ pumps widely with the bore diameter of 75 to 105 mm high-speed diesel match, with a wide range of large-scale use, with an annual output of 50,000 units nationwide holdings of 1.5 million units. At present I pump and diesel cars are also a large number of matches. When the driver controls the throttle, the engine speed should immediately change accordingly. Requires timely response, generally should be about 1 second. If it exceeds this value, the throttle will have a hysteresis. If acceleration and deceleration are not enough timely, operational performance deteriorated, the driving safety factor decreased, the locomotive in climbing gear shifting need to step on two-foot clutch acceleration, or the vehicle into the village, the curve will need to slow down when the driver will bring a lot of inconvenience. Multi-cylinder No. Ⅰ pump throttle lag, in general, are caused by the throttle lever movement hysteresis, while the throttle
