There are three principle areas that affect the oil consumption: piston/cylinder, ventilation system, valve/guide. This test is to measure the oil consumption over a given period of cycle by weighing the oil before and after test 一部分机油进入燃烧室燃烧或者漏掉从而造成机油消耗。3个关键方面影响机油消耗: 活塞/气缸，曲轴箱通风系统，阀门/导杆。本测试时通过测量测试前后机油重量，从而测量 一定循环特定时期内的机油消耗 Method 方法 Step1 步骤1 Warm up engine to specified condition then idle and stop 热机到指定状态，然后怠速，停机 Step2 步骤2 Remove the sump plug fitting, drain oil to a clean bucket for 30 minutes. Replace sump plug fitting. Weight the bucket plus oil. Record the temperature a t start of drain 移除油底壳放油塞，放油到一个干净桶内，持续30分钟。重新装回放油塞。称桶和机 油。记录开始放油时温度 Step3 步骤3 Return oil back to engine and weigh the empty bucket in grams 把机油倒回到发动机里，称空桶，以克计 Step4 步骤4 Start specified test cycle. At the end of cycle, idle and stop 开始制定的测试循环。在循环结束时，怠速停机 Step5 步骤5 Repeat step2 and step3. Note that the temperature at start of drain should be comparable with the recorded previously 重复步骤2和步骤3。注意比较此时放油温度，与之前记录比较是否可比 Step6 步骤6 Oil consumption result could be calculated from the above records 机油消耗记录可以通过以上记录计算得出
