What is TCU in a car?

TCU is the automatic transmission control system, and every model equipped with an automatic transmission will basically have a TCU. The shifting of an automatic transmission relies on commands issued by the TCU, which are then executed through the electro-hydraulic control system to complete the shift. A good automatic transmission not only depends on the transmission itself but also largely depends on the shifting logic of the TCU. The following are the functions of the TCU transmission control system: 1. The transmission control module helps the transmission decide when and how to shift by collecting information from various sensors and the engine control module, thereby improving performance, ensuring smooth shifting, and saving fuel consumption. 2. The Malfunction Indicator Lamp (MIL), also known as the Check Engine Light, illuminates a yellow or red engine symbol on the dashboard when the control module detects a fault. This fault code indicates that the powertrain system (ECU) has received a request from the transmission control system (TCU) to illuminate the malfunction indicator lamp. 3. After troubleshooting a car fault, the fault code needs to be cleared. When clearing the fault code, it is essential to strictly follow the specific method designated for the particular vehicle model. Under no circumstances should the method of disconnecting the battery negative terminal be used to clear the car fault code.

What are the differences between antifreeze of different colors?

Different colors of antifreeze indicate different types. In fact, the color is caused by adding dye to the liquid, which is only used to distinguish it from other liquids and has no other special functional purpose. It also helps users distinguish when choosing antifreeze to prevent mixing different types of antifreeze, which could damage the engine. The functions of antifreeze: Antifreeze is a coolant containing special additives, mainly used in liquid-cooled engine cooling systems. It has excellent properties such as preventing freezing in winter, boiling in summer, and protecting against scale and corrosion throughout the year. Can different antifreeze be mixed? The same brand of antifreeze must be used. Different brands of antifreeze may have different production formulas. If mixed, chemical reactions may occur between multiple additives, causing them to become ineffective. How to choose antifreeze: The basic indicators of antifreeze are freezing point and boiling point. On the market, antifreeze comes in several specifications with freezing points of -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose one with a freezing point at least 10°C lower than the lowest temperature in your region. Antifreeze plays an important role in long-distance vehicle driving.

What is the speed limit for the rightmost lane on the highway?

The rightmost lane is the emergency lane and should not be occupied. The speed limits for the remaining lanes are as follows: the leftmost high-speed lane has a speed limit of 100-120 km/h, and the middle lane has a speed limit of 60-100 km/h. Regarding speed limits, the following points should be noted: Signage speed limits: The speed is restricted according to the limits indicated by speed limit signs and markings on the highway. There is no unified regulation for this speed division, and speed limits may vary in different regions or even on different sections of the same highway. Drivers should always pay attention to the speed limits while driving. Legal speed limits: These refer to the statutory speed limits stipulated in the "Road Traffic Safety Law" and its implementing regulations. For example, on roads without a central dividing line, the speed limit is 40 km/h; on roads with only one motor vehicle lane in the same direction, the speed limit is 70 km/h; when entering or exiting non-motorized lanes, passing through railway crossings, sharp curves, narrow roads, narrow bridges, or when making U-turns, turning, or descending steep slopes, the speed limit is 30 km/h. The maximum speed limit on highways is 120 km/h.

What is the fuel tank capacity of the BYD Tang DM in liters?

There are currently 3 models of the BYD Tang DM available for sale, all with a fuel tank capacity of 53 liters. The vehicle is equipped with a 2.0-liter turbocharged engine and a 6-speed wet dual-clutch transmission (DCT) across all models. All variants feature dual-motor four-wheel drive with a front-mounted four-wheel-drive system. Among vehicles in the same class, the Li ONE 2021 model has a fuel tank capacity of 55 liters, the Ford Edge 2021 has 69 liters, and the Tank 300 2021 has 80 liters. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity marked by automakers is measured from the bottom of the tank to the safety limit level. There is additional space from the safety limit to the tank opening, which is designed to allow for fuel expansion when temperatures rise, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual refueling volume may exceed the calibrated tank capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the instrument panel, marked with E and F. When the needle approaches E, it indicates low fuel, while nearing F means sufficient fuel.

What is the Best Season to Replace a Car Battery?

Due to the low temperatures in winter, the failure rate of car batteries is high, so battery replacements are more common during this season. Below are the precautions for battery usage and replacement methods: Precautions for battery usage: Regularly check the electrolyte level. If it falls below the minimum level mark, replenish it immediately. Continued use in this state will not only accelerate the aging of internal components and shorten the battery's lifespan but may also cause explosions. Keep the battery away from open flames and avoid sparks caused by short circuits near the battery. When charging the battery, carefully read the warning labels and remove the battery from the machine. The battery's electrolyte, dilute sulfuric acid, is corrosive and should not come into direct contact. If electrolyte comes into contact with eyes, skin, or clothing, rinse thoroughly with clean water immediately. If electrolyte enters the eyes, seek medical treatment after rinsing with water. Perform regular maintenance and care for the battery. Battery replacement method: Open the engine hood, remove the red positive terminal of the battery, followed by the black negative terminal. Unscrew the battery's mounting screws and install the corresponding new battery. If the electrolyte level is low, replenish with distilled water or a specialized replenishing solution. During daily driving, regularly check if the vent holes on the battery cover are clear, whether the positive and negative terminals are oxidized, and inspect all parts of the circuit for aging or short circuits. If any issues are found, turn off electrical devices.

What are the symptoms of a diesel engine turbocharger failure?

Diesel engine turbocharger failure can lead to symptoms such as engine power loss, black smoke from the exhaust pipe, oil burning, and low oil levels. If the turbocharger fails, you should not continue driving. If the turbocharger's sealing ring is damaged, exhaust gases can enter the engine's lubrication system through the sealing ring, contaminating the oil and rapidly increasing the crankcase pressure, which can cause excessive oil consumption and oil burning. Relevant information about turbochargers is as follows: 1. Turbocharger: A piston-type aircraft engine uses a turbocharger to increase the intake pressure in the cylinders. Before entering the engine cylinders, the air is compressed by the turbocharger to increase its density, allowing more air to fill the cylinders and thereby increasing engine power. Engines equipped with turbochargers can not only deliver greater takeoff power but also improve the engine's altitude characteristics. 2. Automotive turbocharger: Turbocharging is a technology that compresses air before supplying it to the cylinders to increase air density and intake volume. The purpose is to increase air intake, enhance power, improve fuel economy, and reduce emissions.
