我车场97台日本尼桑自卸车,使用7～8年来,绝大多数发动机使用情况不佳,多为早期磨损,首先表现在气缸上机油,机油消耗激增尤为严重。有的车辆在一个月内,甚至有的车在几天内突然猛耗机油,最多者高达每百公里耗机油20公升,这一类发动机只有进行大修恢复。也有的车辆经大修后仅行驶几千公里就开始耗机油。多年来,耗机油严重成为影响该车型技术状况的主要故障。发动机出现上述故障。有多方面的原因,如润滑不良,修理保养质量差、配件耐磨性
97 sets of Japanese Nissan Dump Truck in my yard, the use of 7 to 8 years, the vast majority of poor engine performance, mostly for the early wear and tear, first manifested in the cylinder oil, oil consumption surge is particularly serious. Some vehicles in a month, and even some of the sudden sudden consumption of oil in a few days, up to up to 100 liters per 100 kilometers of oil consumption of 20 liters, this type of engine is only overhaul recovery.

There are many reasons, such as poor lubrication, repair and maintenance of poor quality, wear parts
