The “burner oil” has a great harm to the sprinkler. It not only damages the oxygen sensor of the sprinkler too quickly, but also causes adverse effects such as increased carbon deposition in the combustion chamber, unstable idling speed, poor acceleration, increased fuel consumption, and excessive exhaust emissions. Due to lack of engine lubrication, the engine will cause damage that is difficult to repair and even be scrapped, resulting in a substantial increase in maintenance costs and even hidden dangers. For sprinkler drivers, how do you tell if the sprinkler has "burner oil"? Let's take a look at:

Phenomenon 1: The main performance of the “burning oil” of the sprinkler is that the tail emits blue exhaust gas when driving, which means that too much oil enters the combustion chamber to participate in the combustion.

Phenomenon 2: The oil dipstick detects excessive oil consumption.

Detection method: After the cold car starts in the early morning, check whether the exhaust pipe will emit blue smoke; whether the exhaust pipe has a lot of blue smoke when the sprinkler is driving or when the place slams on the accelerator; besides the exhaust pipe, the engine oil From time to time, I also smoke blue smoke.

Experts said that because valve seals wear out and wear out after prolonged use, they can no longer achieve a good sealing effect. Therefore, some sprinklers that have a long service life or have many kilometers traveled are more prone to “burning oil”. The reason for choosing to perform the inspection in the early morning cold car is that when the sprinkler engine is not running for a long time, the oil will flow into the cylinder through the gap of the valve oil seal under the action of gravity. As soon as the engine is started, the oil in the cylinder will be burned under the effect of high temperature and high pressure, producing a large amount of blue smoke. The test method of slamming the accelerator is mainly to check whether there is loose seal between the piston ring of the sprinkler engine and the cylinder wall. When the sprinkler truck accelerates rapidly, the frequency of up and down movement of the piston ring is accelerated, and residual oil on the cylinder wall is easily brought into the combustion chamber by the piston ring, resulting in “burning oil”. If, under any circumstances, the exhaust pipe emits blue smoke, and the oil outlet emits blue smoke from time to time, it indicates that the watering of the sprinkler engine has become quite serious. The sprinkler needs to be overhauled in time, otherwise it will cause serious accidents. .

Engine oil is crucial to the protection of the engine. There are many causes of “burning oil” phenomenon. Engine oil is volatile, engine running-in, engine type, etc. may cause the engine to “burn oil”, but by strengthening the daily maintenance of the car, This risk can be mitigated and avoided. So, what maintenance tips should be taken care of?

1, develop a good inspection habits. The oil should be regularly inspected according to the different conditions of use during regular routine and daily maintenance. If the oil level exceeds the lower limit, it should be added in time. For vehicles that have a longer service life and mileage and are often used in harsh conditions, the frequency of inspections should be increased accordingly. In this way, even if the vehicle appears to "burn oil", it can achieve "early detection and early treatment" and reduce maintenance costs.

2, choose better quality gasoline. After the additives in gasoline are oxidized, a gelatinous substance is formed. After the fuel is injected into the combustion chamber, carbon deposits are formed in the intake valve, piston top, piston ring groove, combustion chamber, spark plug, etc., which intensify these parts. The aging causes "burner oil." Therefore, the use of better quality gasoline can reduce the phenomenon of “burning oil”.

3, regular maintenance of vehicles. The maintenance cycle of the vehicle is based on the normal driving conditions of the vehicle. If the vehicle is used in a relatively poor condition, the maintenance cycle and the prescribed number of kilometers should be shortened according to the actual situation.
