We all know that "burner oil" has a great harm to the vehicle. It will not only damage the vehicle's oxygen sensor too quickly, but also cause adverse effects such as increased carbon deposition in the combustion chamber, unstable idling speed, poor acceleration, increased fuel consumption, and excessive exhaust emissions. In severe cases, the lack of engine lubrication will cause the engine to cause unrepairable damage or even be scrapped, resulting in a substantial increase in maintenance costs and even hidden dangers. However, for ordinary owners, how do you distinguish whether the car has "burning oil" phenomenon?
Identifying whether your car is “burning oil†can be distinguished from the following two phenomena: Phenomenon 1: The main performance of “burning oil†is to emit blue exhaust at the tail when driving, which means that too much oil enters the combustion Room involved in 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 emits a lot of blue smoke when the vehicle is driving or when the engine slams on the throttle in place; besides the exhaust pipe, the oil port From time to time also take the blue smoke.
Experts have analyzed that valve seals are aging and worn after prolonged use, and can no longer achieve a good sealing effect. Therefore, some vehicles with a long service life or a large number of driving kilometers are more prone to “burning oilâ€. The reason for choosing to test in the early morning cold car is that when the 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 effect 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 method of slamming the throttle is mainly to check whether there is loose seal between the piston ring of the engine and the cylinder wall. When the vehicle 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 oilâ€. If, under any circumstances, the exhaust pipe emits blue smoke and the engine oil port emits blue smoke from time to time, it indicates that the wear of the engine has become quite serious and the vehicle needs to be overhauled in time. Otherwise, serious accidents may occur.
Maintenance of engine oil is critical to the protection of the engine. There are many causes of “burning oil†phenomenon. The volatile oil, the engine running-in, the engine type, etc. may cause the engine to “burn oilâ€, but by strengthening the daily life of the car. Maintenance can reduce and avoid this risk. So, what maintenance tips should be taken care of?
1. Develop 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 with long service life and mileage, which are often used under 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. Use 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, the top of the piston, the piston ring groove, the combustion chamber, and the spark plug, which intensifies these parts. The aging causes "burning oil." Therefore, the use of better quality gasoline can reduce the phenomenon of “burning oilâ€.
3. Regularly maintain the vehicle. 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.
4. Select a better quality oil. Motor oil should try to choose a well-known brand. When conditions permit, the use of fully synthetic motor oil is better. The high quality engine oil not only has good cleaning performance, but also minimizes the wear of the components of sludge and carbon deposits, thereby reducing the occurrence of “burning oilâ€. At the same time, it also has better stability, making the oil in the engine at high temperatures. Maintaining proper viscosity levels at high speeds ensures effective sealing and reduces oil consumption.
A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium.
The basic hoist has two important characteristics to define it: Lifting medium and power type. The lifting medium is either wire rope, wrapped around a drum, or load-chain, raised by a pulley with a special profile to engage the chain. The power can be provided by different means. Common means are hydraulics, electrical and air driven motors. Both the wire rope hoist and chain hoist have been in common use since the 1800s, however mass production of an Electric Hoist did not start until the early 1900s and was first adapted by Germany. A hoist can be built as one integral-package unit, designed for cost-effective purchasing and moderate use, or it can be built as a built-up custom unit, designed for durability and performance. The built-up hoist will be much more expensive, but will also be easier to repair and more durable. Package units were once regarded as being designed for light to moderate usage, but since the 60s this has changed. Built-up units are designed for heavy to severe service, but over the years that market has decreased in size since the advent of the more durable packaged hoist. A machine shop or fabricating shop will use an integral-package hoist, while a Steel Mill or NASA would use a built-up unit to meet durability, performance, and repairability requirements. NASA has also seen a change in the use of package hoists. The NASA Astronaut training pool, for example, utilizes cranes with packaged hoists.
