What does BYD powertrain malfunction mean?

1 Answers

BYD powertrain malfunction refers to failures occurring in the entire mechanical arrangement process that transmits the power generated by the engine to the wheels through a series of power transfers. Below are detailed explanations: 1. Causes of malfunction: Incorrect ignition timing or premature ignition causing early combustion and detonation of the air-fuel mixture; misfiring or weak sparks from spark plugs due to ignition system failures; decreased cylinder compression pressure caused by severe wear of pistons, piston rings, and cylinders, leading to increased clearance between them and reduced sealing, resulting in cylinder head leakage; reduced suction due to poor sealing and air leakage in the crankcase. 2. Solutions: Check if the air filter is clogged and clean it if necessary. Ensure the throttle valve opens fully when the accelerator pedal is fully depressed; otherwise, adjust the throttle cable or perform relearning for the pedal position sensor and throttle position sensor.

What Causes the Smell of Burning Rubber After Driving for a While?

Reasons for the smell of burning rubber after driving for a while: 1. For new cars: This smell is generally normal for new cars, as various rubber and plastic components are new and produce this odor under high temperatures, which will gradually fade over time; 2. Incomplete combustion of gasoline: When starting the car in winter, due to low temperatures, it becomes harder for gasoline to vaporize, affecting combustion. Some unburned gasoline molecules are expelled through the exhaust pipe and then enter the car via the external circulation; 3. Friction from brake pads: If the handbrake is not fully released or the brake pads contain larger metal particles, it can produce a burning rubber smell; 4. Burnt clutch smell: If the clutch plate in the transmission slips, causing high temperatures, it can also produce a burning rubber smell.

How to Check the Vehicle Production Month Using the VIN?

The 10th digit of the VIN represents the vehicle's production year, but the specific production month cannot be determined. The production year may be represented by a number or a letter, following a 30-year cycle code system, where the letter 'O' and the number '10' are not used. Generally, the VIN is located on the right door frame of the vehicle, though some models may place it on the left. Simply open the door and look carefully to find it. The VIN is a unique 17-character alphanumeric code assigned by the manufacturer to identify a vehicle. Through its combination of letters and numbers, the VIN ensures that no two vehicles of the same model will have the same code within a 30-year period, providing a unique identifier for each vehicle, hence it is often referred to as the 'car's ID card'.

What are the symptoms of clutch slippage in an automatic transmission?

Symptoms of clutch slippage in an automatic transmission include: 1. When pressing the accelerator pedal during startup, the engine speed increases quickly but the vehicle speed rises slowly; 2. During driving, when pressing the accelerator pedal to accelerate, the engine speed increases but the vehicle speed does not improve; 3. The engine speed is very high, and the vehicle runs normally on flat roads, but lacks power when going uphill or under heavy load; 4. Increased fuel consumption. Causes of clutch slippage in an automatic transmission: 1. Insufficient or dirty transmission fluid, leading to incomplete clutch engagement and disengagement; 2. Wear and burning of the clutch disc due to prolonged use, preventing the clutch from being tightly pressed; 3. Excessive wear of the oil pump or leakage in the main oil circuit, resulting in low oil pressure; 4. Damage to the piston seal ring of the clutch or brake, causing oil leakage.

How much does a car depreciate after being in stock for one year?

A car that has been in stock for one year depreciates by 15%. According to the automotive industry's regulations, the calculation method for car depreciation is as follows: The depreciation rate is 15% for the first three years; 10% for years 4 to 7; and 5% for the final three years. This means that a new car priced at 200,000 yuan would typically sell for about 170,000 yuan as a used car after one year. A car that has been in stock for more than three months is considered a stock car. Although stock cars have not been used, they cannot be classified as new cars. If a car remains unused for an extended period, its components may deteriorate, especially the engine, battery, tires, and plastic parts. If a new car has been in stock for over three years, it is generally no longer usable. However, if a car has been in stock for three to four months and the dealer has maintained it well, it can still be purchased at a discounted price, offering relatively good value for money.

Is it okay to add one liter less transmission fluid?

It is not acceptable to add one liter less transmission fluid. Transmission fluid must not be underfilled, as insufficient fluid can affect the lubrication and cooling of the transmission. In severe cases, it may even prevent the transmission from shifting gears. The transmission is a crucial component in a vehicle, responsible for changing speed and torque. Without a transmission, a car cannot operate properly. There are two main types of transmissions in vehicles: manual transmissions and automatic transmissions. Common types of transmissions in cars include: AT (automatic transmission), CVT (continuously variable transmission), and dual-clutch transmissions. Transmissions achieve speed and torque changes through different gear combinations. An automatic transmission (AT) consists of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system.

What are the advantages and disadvantages of mid-size cars and compact cars?

Mid-size cars and compact cars have the following advantages and disadvantages: 1. Advantages of mid-size cars: High level of luxury; Disadvantages: Narrow interior space, comfort, visibility, and space are not as good as SUVs. 2. Advantages of compact cars: They are common family cars, usually hatchbacks, with ideal overall cost performance; Disadvantages: The power of compact cars is generally not as good as that of large cars, and the stability is relatively poor. Sometimes, the car is prone to minor bumps and scratches. Mid-size cars generally refer to cars with a wheelbase of 2.6 to 2.7 meters, a body length of 4.5 to 4.8 meters, and an engine displacement of 1.6 to 2.0 liters. The number of seats is usually five, while seven-seaters are considered commercial vehicles. In foreign countries, family cars are generally compact cars, with a standard total length of 4.2 to 4.6 meters, a wheelbase of 2.4 to 2.7 meters, and an engine displacement of around 1.6 to 2.0 liters.
