康明斯发动机N/K全系列发动机不好启动的原因与排除?

日兴动力建议按以下方法处理

Nikko power suggestion processing according to the following method

一、油箱没油或者燃油油位低导致不能正常供油引起的，给油箱加满油就可以了。

A tank, no oil or fuel oil low result can not be normal oil supply caused, fill up the tank with oil on it.

二、喷油器出现问题，

Problem two, injector,

(1) 喷油器O型密封圈损坏或丢失，检查密封圈；

(1) the fuel injectors O type sealing ring is damaged or lost, check the sealing ring;

(2) 喷油器有污物或者调节不当，对喷油器重新调整，检查清洗滤网或者更换。

(2) the injector with dirt or improperly adjusted, re adjustment of the fuel injector, check the cleaning filter or replacement.

三、进气系统问题

Three, the intake system

(1)进气管堵塞，检查空气滤清器和进气管路；

(1) the intake pipe is blocked, check the air filter and the intake pipe;

(2)进气系统阻力超出技术规范严格参照规范来执行修改。

(2) the intake system resistance beyond the technical specification strictly according to regulations to implement change.

四、燃油油道中存在杂物堵塞进气管，着重检查空气滤清器和进气管路，清除杂物。

There are four blocked the intake pipe, fuel oil, check on the air cleaner and the air inlet pipe, debris removal.

五、燃油泵出现问题

Five, the fuel pump problem

(1)燃油输油泵进口滤网堵塞解决办法就是清除污物；

(1) the fuel pump inlet filter blockage solution is to remove the dirt;

(2)齿轮泵驱动轴断裂或者错位，重新调整或者更换新的康明斯驱动轴配件。

(2) gear pump driving shaft fracture or dislocation, re adjust or replace the new Cummins drive shaft parts.

六、燃油进油口问题

Six, the fuel oil inlet problem

(1)进油口因杂物赌塞，仔细检查滤清器是否存在异物，及时清理；

(1) the inlet due to debris jam, carefully check whether there is foreign body cleaning filter;

(2)进油口漏气，仔细检查接头和软管是否接紧。

(2) the inlet air leakage, carefully check the fittings and hose is connected tightly.

七、燃油质量问题

Seven, fuel quality

(1)燃油等级与应用类型不符；

(1) the fuel level and application type does not match;

(2)劣质燃油或者燃油中混有水。及时更换合乎等级的正规燃油。

(2) the inferior fuel oil or fuel oil mixed with water. Replace the normal fuel a level in time.

八、燃油电磁阀出现问题一般燃油电磁阀因线路接触不良或者断线，试着手动控制开关启动看看，同时检查线路是否出现问题。康明斯N/K系列柴油发动机相对来说相较Q系列电喷机来说简单多了，最主要的就是如何通过这个异常启动来发现发动机是否出现问题，如何在日常运行、维修的过程中去通过以上原因参照解决启动问题，是维持发动机正常使用寿命的必要选择。

Eight, fuel solenoid valve problems generally fuel solenoid valve because of poor contact or line break, try to have a look at the manual control switch, check wiring problems. Cummins N/K series diesel engine is compared with Q series injection machine is simple, the most important is how to discover whether the engine problems through the abnormal start, how to go through the above reasons refer to solve problems in the process of starting daily operation, repair, is a necessary choice to maintain normal engine service life.

康明斯柴油发动机机油消耗大或发动机大修后烧机油？

Large or overhaul of engine oil consumption for Cummins diesel engine burning oil?

一、康明斯发动机为什么会消耗机油？

Why, Cummings engine oil consumption?

为了降低发动机各运动部件的磨耗,减少机械的摩擦阻力,延长机器的寿命,具有相对运动的零件之间必须施加润滑。消耗机油的2种方式：

In order to reduce the moving parts of the engine wear, reducing friction machine, prolong the service life of the machine, with the relative motion between the parts must be applied lubrication. 2 ways of consumption of oil:

1:燃烧室内消耗

1: combustion chamber consumption

2:排出发动机体外

The 2: engine through in vitro

二：康明斯缸套、活塞是机油消耗的主要部位

Two: Cummings is the main part of cylinder liner, piston oil consumption

1:缸体表面加工出的储存润滑油的花纹随着机器的磨和,花纹的尖角在逐步磨平,因此机油的消耗也在逐渐减少

The 1: store oil cylinder machined surface pattern with machine and grinding, pattern angle gradually removed, therefore the oil consumption is also reduced gradually

三：康明斯活塞上行时机油被泵入燃烧室燃烧后,被消耗

Three: Cummings when piston upward oil is pumped into the combustion chamber, is consumed

四：康明斯气门和气门导管之间也有机油消耗

Four: there are oil consumption between the Cummings valve and valve guide

气门和气门导管也是一对热负荷较大的运动副,润滑的方式是发动机机油飞溅润滑,润滑后的机油也流到燃烧室内燃烧致使损耗,但是该机油的有效消耗能够有效的延长气门和气门导管的寿命

Motion of the valve and valve guide is a pair of large heat load, lubrication is engine oil splash lubrication, the lubrication oil flow to the burn after the loss of the combustion chamber, but effective consumption of the engine oil can effectively prolong the lifetime of valve and valve guide

五：康明斯涡轮增压器启动和关机时消耗部分机油

Five: Turbocharger startup and shutdown time consumption part of oil

由于废气涡轮增压器是依靠进排气的平衡压力密封润滑油的,因此,在启动和关闭机器时,总是要有少量的发动机机油漏出,这也是所有采用废气涡轮增压器所具有的特点.

Because the turbocharger is dependent on the balance pressure inlet and exhaust sealing lubricating oil, therefore, in the start up and shut down the machine, always have a small amount of engine oil leakage, which is all the exhaust turbocharger features

六：康明斯柴油发动机下排气也排出部分机油

Six: Cummings diesel engine exhaust and exhaust part oil

为了使康明斯发动机能够连续的输出功率,曲轴箱必须和大气相同,因此必须有一个管道来连接曲轴箱和大气,俗称”下排气管”,通过活塞环泄露的少量高温燃气通过”下排气管”导入大气当中,同时将由于曲轴高速旋转时激起的机油油雾排到大气当中,致使有少量的机油消耗.

In order to make the Cummings engine is capable of continuous output power, the crankshaft box must be the same and the atmosphere, so there must be a pipeline to connect the crankcase and the atmosphere, commonly known as the "tube", a small amount of high temperature exhaust gas through the piston rings leak through the "exhaust pipe" into the atmosphere when, at the same time, because the oil mist stirred crankshaft when the rotary speed of the discharge into the atmosphere, causing a small amount of oil consumption

七：为什么不同发动机添加机油周期不一样？

Seven: why different engine add oil cycle is not the same?

康明斯发动机油底壳的容积不同，油底壳形状不一样，油标尺设定刻度不一样。所以添加的频次也不一样，但正常情况下每千升柴油所消耗的机油量比例差别不大。

The volume of the Cummings engine oil pan, oil bottom shell shape is different, the oil scale set the scale is not the same. So adding frequency is not the same, but little difference in oil consumption per kiloliter diesel ratio under normal conditions.

八：康明斯发动机大修后烧机油？

Eight: Cummings engine overhaul burning oil?

康明斯柴油发动机油的正常消耗量为每消耗100吨柴油，消耗机油2.5kg。若超标，则视为烧机油故障。其原因有:

Normal consumption of Cummins diesel engine oil quantity for each consumed 100 tons of diesel oil, oil consumption for 2.5kg. If exceed the standard, is regarded as a burning oil fault. The reasons are:

1加用了汽油机机油(包括美国的美孚汽油机机油);

1 with the gasoline engine oil (including oil Mobil gasoline engine of American);

2汽缸密封不良(如活塞环失效，拉缸等);

2 cylinder seals bad (such as failure of piston ring cylinder, etc.);

3增压器两端密封损坏;

3 supercharger ends seal damage;

4进气门挡油罩掉出或损坏。

4 inlet valve oil blocking cover out of or damage.

5发动机大修后在磨合期内可能是有点耗机油

The 5 engine overhaul in the running in period may be a little oil consumption

6发动机在大修时选择配件不当

The 6 engine in the overhaul of improper selection of accessories
