Does Replacing a Trunk Lid Require Painting?

Replacing an original trunk lid requires painting because the original trunk lid does not come with a painted surface. Therefore, it needs to be painted at the 4S shop before installation. The automotive body paint is complex and consists of four layers. From the inside out, they are the electrophoretic layer, the primer layer, the base coat layer, and the clear coat layer. Each layer has its unique painting process and function. Electrophoretic Layer: After the entire car body is assembled, robots immerse the body in an electrophoretic tank to form an electrophoretic layer. The main function of this layer is rust prevention. Primer Layer: After the electrophoretic layer is formed on the body surface, robots spray the primer layer. This layer also serves to prevent rust and enhances adhesion to the next layer of body paint. Base Coat Layer: Above the primer layer is the base coat layer, which primarily serves an aesthetic purpose. The various car body colors we see daily are presented by this layer. Clear Coat Layer: The outermost layer is the clear coat, which protects the base coat and enhances its gloss. The clear coat is the most vulnerable layer, as most minor scratches typically remain on this layer.

What is the fuel tank capacity of the BMW X4 in liters?

BMW X4 has a fuel tank capacity of 65 liters, which is the officially announced data. The recommended fuel grade for BMW X4 is 95, with a fuel consumption of 8.1-8.2L per 100 kilometers. A full tank can cover a distance of 792-802 kilometers. During daily driving, it is necessary to always pay attention to the remaining fuel level in the tank. The fuel level is usually observed through the fuel gauge inside the car. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments. It is advisable to refuel when there are only 2 segments left to avoid running out of fuel midway. In the actual refueling process, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity specified by the car manufacturer is measured from the bottom of the tank to the safe limit, and there is still some space from the safe limit to the tank opening. This space is reserved to allow the fuel to expand when the temperature rises without overflowing the tank. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity.

Does modifying the middle cylinder of a motorcycle have any impact?

Modifying the middle cylinder of a motorcycle has an impact. It increases fuel consumption, adds load to the crankshaft and valves, and reduces the cylinder compression ratio. Since the surfaces of the matching components cannot be machined to a completely ideal state, there are also certain deviations in their relative positions. The moving parts will experience intense friction and generate significant heat. If not used carefully, the friction surfaces may become damaged, severely affecting the motorcycle's performance and lifespan. Control the speed: Strictly follow the different speed limits specified in the user manual during the break-in period. Avoid overloading by keeping the load below two-thirds of the motorcycle's maximum capacity and choose smoother roads for driving. Control the driving time: Avoid prolonged engine operation. Change the engine oil frequently to remove metal particles generated during the break-in process. It is recommended to change the engine oil three times during the break-in period.

What Does the After-Sales Warranty for New Cars Include?

New car after-sales warranties generally include the whole vehicle warranty and the powertrain warranty. Whole Vehicle Warranty: The whole vehicle warranty means that various components can be replaced for free if they are confirmed to be damaged due to quality issues rather than human factors, such as speedometers or air conditioning components. If these issues occur within the warranty period or within the specified mileage, they can be repaired for free. However, the whole vehicle warranty does not actually mean that every component enjoys the same warranty service; instead, it is divided by component. Powertrain Warranty: The powertrain warranty covers the engine and transmission. If these two components have quality issues, they will be covered under warranty, provided that regular maintenance is performed at a 4S dealership according to the maintenance manual. Generally, components that are prone to damage or wear, such as batteries, shock absorbers, wipers, rubber parts, and audio equipment, have shorter warranty periods, while components that are less prone to damage, such as engine blocks, have longer warranty periods. Some components, like tires, may be declared non-warrantable by certain car manufacturers.
