Is It Normal for a Car's Rear Wheels to Have a Negative Camber?

It is normal for a car's rear wheels to have a negative camber, but ordinary family cars typically do not use this setup. A negative camber on the rear wheels refers to an inward tilt of the tires, a structure more commonly seen in sports cars and race cars. This design is used because racetracks have many curves, and the negative camber helps the vehicle achieve better grip on the ground. Generally, after modifying a car to have a negative camber, the vehicle's body height and chassis will be lowered. Cars with negative camber tend to have heavier steering systems, smaller tire contact patches with the ground during straight-line driving, longer braking distances, and more severe tire wear. This is why race cars frequently need to replace their tires.

What is the sign of insufficient engine coolant?

The insufficient engine coolant warning light displays a thermometer shape, and there is also a kettle-shaped indicator. The functions of antifreeze are introduced as follows: Cooling function: Cooling is the basic function of coolant. The engine generates a large amount of heat during operation, with 60% of this heat being dissipated into the surrounding space through the cooling system. Water and methanol coolants have low boiling points and are prone to boiling. If the vehicle operates under conditions where the coolant is boiling, even for a short period, it can cause engine damage or even complete failure. Anti-scaling function: The coolant should minimize the formation of scale during circulation to prevent clogging of the circulation pipes and affecting the heat dissipation function of the cooling system. In summary, one should be cautious when selecting and adding coolant.

Can You Still Drive with a Transmission Fault?

You can still drive with a transmission fault, but for safety reasons, it is recommended to repair it as soon as possible. The main cause of transmission faults is often a dirty valve body. A dirty transmission valve body can compromise the quality and friction characteristics of the transmission fluid. This increases friction and wear, while sludge can also form inside the transmission, leading to blockages in the valve body and pipelines. This disrupts the proper regulation of oil pressure, resulting in transmission issues. Transmissions can be divided into two types: manual and automatic. Manual transmissions primarily consist of gears and shafts, achieving speed and torque changes through different gear combinations. Automatic transmissions (AT) are composed of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system.

Why Does Water Come Out of the Exhaust Pipe in Winter?

In winter, water comes out of the exhaust pipe because the three-way catalytic converter releases water vapor during operation. As the temperature of the exhaust pipe decreases, water droplets form and flow out with the exhaust gas from the exhaust port. Below is a detailed introduction to the three-way catalytic converter in cars: Water Discharge Phenomenon: When the car is idling or running at high speed, water often drips or flows from the exhaust port at the rear of the exhaust pipe or the drainage hole under the muffler. This indicates that the engine is burning well and the three-way catalytic converter is functioning properly. Working Principle: The working principle is that after the car's exhaust gas passes through the three-way catalytic converter, harmful gases such as carbon monoxide in the exhaust are converted into carbon dioxide and water through chemical reactions in the three-way catalytic converter.
