In the early stage of the engine, the water temperature is very fast; when the water temperature gauge indicates 80, the heating rate slows down, it indicates that the thermostat is working normally. On the contrary, if the water temperature increases rapidly, when the internal pressure reaches a certain degree, the boiling water suddenly overflows, it indicates that the main valve is stuck and suddenly opens. When the water temperature gauge indicates 70 ℃ - 80 ℃, open the radiator cap and radiator drain switch, and feel the water temperature by hand. If both hands are tied, it means that the thermostat works normally; if the water temperature at the radiator water inlet is low, and there is no water outflow or little water flow at the inlet pipe of the radiator upper water chamber, it means that the main valve of the thermostat cannot be opened. If the thermostat is stuck or not closed tightly, it should be removed for cleaning or correction, and should not be used with mercy.
应用不异法，拆下策念头的氛围滤清器，假设此时打鱼注册送分 主意机排挤的不是黑烟，那申明是氛围滤清器有严峻的梗阻，应消除梗阻也许变更滤芯，变更新的滤芯结果很是好。由于策念头喷油泵和调速器调剂不得当，使油嘴的喷油量太大，超越了打鱼注册送分 策念头的每一个轮回喷油数目，也许是有对照严峻的后滴油景象等，组成供油量过大。
Using the communication method, remove the air filter of the engine. Assuming that the smoke emitted by the concrete mixer is not black smoke, it means that the air filter is seriously blocked. It is necessary to eliminate the blocking. Maybe it is very good to change the filter element and change the new filter element. Because the fuel injection pump and governor of the engine are not properly adjusted, the fuel injection quantity of the nozzle is too large, which exceeds the fuel injection quantity of each cycle of the concrete mixer engine. Maybe there is a serious phenomenon of post drip, which constitutes the excessive fuel supply.
在装有涡轮增压装备的打鱼注册送分 柴油机，应按打鱼注册送分 修补守则上的涡轮增压装备的缺点确诊方法中断确诊与打扫，或选用置换法，即换用同类型的涡轮增压器，若不异后不玄色烟雾就可以也许证实打鱼注册送分 柴油机冒黑烟是涡轮增压器破坏所爆发的。柴油是碳氢化合物，假设策念头在缺少氧气的前提下停歇，简略组成停歇不充实，不完好，会致使局部不完好停歇的碳元素组成游离碳，混入废气排挤，致使爆发了玄色的烟雾。
The diesel engine of the concrete mixer equipped with turbocharging equipment should be diagnosed and cleaned intermittently according to the defect diagnosis method of the turbocharging equipment in the repair code of the concrete mixer, or the replacement method should be selected, that is, the same type of turbocharger should be used. If there is no black smoke after communication, it can be proved that the black smoke of the diesel engine of the concrete mixer is caused by the damage of the turbocharger. Diesel is a hydrocarbon. Assuming that the engine stops under the condition of short oxygen, the simple composition of stopping is not sufficient, which will lead to the formation of free carbon by some carbon elements without stopping, which will be mixed into the exhaust gas and lead to black smoke.
掀开散热器加水口盖，若散热器内冷却水宁静，则标明节温器任务一般，不然，则标明节温器任务很是。这是由于，在水温低于70℃时，节温器胀大筒处于延长环境，主阀门封闭;当水温高于80℃时，胀大筒胀大，主阀门慢慢掀开，散热器内轮回水开端勾当。
Open the radiator water inlet cap. If the cooling water in the radiator is quiet, it indicates that the thermostat works normally. Otherwise, it indicates that the thermostat works abnormally. This is because, when the water temperature is lower than 70 ℃, the expansion cylinder of the thermostat is in the shortening condition, and the main valve is closed; when the water temperature is higher than 80 ℃, the expansion cylinder is expanded, and the main valve is gradually opened, and the circulating water in the radiator is initially active.
当水温表唆使70℃以下时，散热器进水管处如有水勾当，水温温热，则表季节温器主阀门封闭不严，使冷却水过早大轮回。假设是细微的脏污，可不必打金鱼 车身洗濯剂，间接用毛巾擦，当即就可以也许擦干净。但假设玻璃上附着的是油膜，用凡是的方法很难清除，这时候候，须要动用清除油膜公用的玻璃洗濯剂来擦洗，它的结果是可以也许使油膜不易附在玻璃上。应用玻璃公用洗濯产物前，应先洗濯车窗，不然洗濯结果会打折扣。玻璃洗濯剂在干了今后，就像打蜡不异会变白，只要用柔嫩的布将它拭去便可。
When the water temperature gauge indicates below 70 ℃, if there is water movement at the radiator inlet pipe and the water temperature is warm, the main valve of the thermometer is not closed tightly, which makes the cooling water circulate prematurely. Assuming that it is a fine dirt, you don't need to mix the car body cleaning agent, just use a towel to clean it immediately. But suppose that the oil film is attached to the glass, and it is difficult to clean it with the usual method. At this time, it is necessary to use the special glass cleaning agent to clean the oil film. Its effect is that the oil film is not easy to adhere to the glass. Before using the special cleaning products for glass, the windows should be cleaned first, otherwise the cleaning effect will be compromised. After the glass cleaner is dry, it will turn white just like waxing. Just wipe it off with a soft cloth.
