Is it necessary to apply a protective film on the side mirror housing?

In the absence of other reasons, you can apply a protective film to the side mirror. The functions of the side mirror waterproof film: Waterproofing is the most important function of this side mirror film. In addition, it also has effects such as oil resistance, anti-fogging, scratch resistance, and anti-glare from high beams. The principle of the side mirror waterproof film: The side mirror water repellent (not called rainproof film), also known as glass rainproof film, has a very simple principle. It forms a layer of film on the glass surface, allowing rainwater to slide off quickly. In fact, applying dishwashing liquid or toothpaste can also achieve this effect, but the duration will be shorter. Using products specifically designed for glass will be much more effective.

What is the principle behind easier starting when opening the choke?

Opening the choke makes starting easier by enriching the fuel mixture. Specific reasons: The motorcycle choke is a mechanism specifically designed for cold starts. The choke is used to enrich the mixture during startup, meaning it provides more fuel during ignition. This is because during a cold start, the carburetor has not yet vaporized the fuel, resulting in a lean air-fuel mixture. Therefore, in winter, slide carburetors generally require the use of a choke to enrich the mixture. However, in summer when temperatures are high, the choke is usually not needed for starting. Other methods to assist starting: In winter, when temperatures are low, engine oil tends to thicken and clump together. This often causes motorcycle engines to struggle, resulting in low-speed rotation. Additionally, running in humid or dusty areas can allow more impurities to enter the cylinder, potentially clogging oil passages. These situations require frequent oil changes. Different temperatures require different types of engine oil, and timely oil changes can improve vehicle performance.

Why Does the Steering Wheel Become Heavy?

Possible reasons for a heavy steering wheel are as follows: Power Steering Fluid Issue: The most likely cause is dirty or deteriorated power steering fluid, which cannot build sufficient pressure, resulting in reduced power assistance and a heavier steering wheel. Replacing the power steering fluid can resolve this issue. Power Steering Pump Issue: Another possibility is that the power steering pump is about to fail, leading to insufficient oil pressure and reduced power assistance, making the steering wheel heavy. Other causes include overly tight bearings in the steering system, poor lubrication, tight steering tie rod ball joints, or lack of lubrication causing stiffness. Tire Issue: Insufficient tire pressure increases the contact area between the tire and the ground, increasing friction when turning the steering wheel, making it feel heavier.

Should Left-Turning Vehicles Yield to Straight-Going Vehicles?

Left-turning vehicles should yield to straight-going vehicles. The situation where straight-going vehicles yield to turning vehicles applies to secondary roads yielding to main roads: In urban areas, the traffic volume on main roads is relatively high. Generally, main roads have priority. Therefore, if the secondary road is a straight lane and the main road involves turning vehicles, vehicles on the secondary road should yield to turning vehicles on the main road. If an accident occurs due to the secondary road vehicle not yielding, the secondary road vehicle, even if going straight, will bear full responsibility. Intersections with yield signs: These signs are usually placed at the junctions between secondary roads and main roads. Their primary purpose is to remind secondary road vehicles to yield to turning vehicles on the main road. Yield signs are further divided into two types: stop signs and slow-down signs. If a driver encounters a yield sign at an intersection, they must observe the main road traffic and only proceed into the intersection after confirming it is safe.

Will the Motor of a Four-Wheel Drive Vehicle Expire?

The motor of a four-wheel drive vehicle will be scrapped after exceeding its service life. Motor: The term "motor" is a transliteration of the English word "motor," referring to an electric motor or engine. Its working principle involves the rotation of energized coils in a magnetic field, which drives the starter rotor to rotate. The small gear on the rotor then drives the engine flywheel to rotate. This technology was first used in the automotive industry in 1912. Motor Structure: This component consists of an internal gear ring and a matching gear or rotor. The internal gear ring is fixed to the housing, and the oil entering from the oil port pushes the rotor to revolve around a central point. This slowly rotating rotor drives the output through a spline shaft, forming a cycloidal hydraulic motor.
