What to Do When the Starter Fails to Start?

If the starter fails to start, it is necessary to promptly visit a 4S shop for repair. The reasons for the starter not starting or operating weakly include the following: 1. The battery is dead or has insufficient power, resulting in the starter being unable to rotate or rotating slowly. 2. Loose or detached starter wiring, or failure of the switch or solenoid switch. 3. Worn brushes or misaligned brush surfaces, weak springs, leading to poor contact with the commutator. 4. Short circuits or open circuits in the field coils or armature coils. 5. Dirty commutator or protruding mica segments, causing poor contact between the brushes and the commutator.

What is the best engine oil for Buick Verano maintenance?

For Buick Verano maintenance, you can choose engine oil brands such as Mobil, Castrol, and Shell. The recommended engine oil specification for the Buick Verano, as stated in the manual, is 5W-30. Any oil that meets this specification can be used. The viscosity of engine oil changes with temperature, so it is important to pay special attention to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity—5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, ensuring smoother cold starts for the car. The second number represents the kinematic viscosity of the oil at 100°C. A higher number means the oil can maintain its viscosity better at high temperatures, which can be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in a Buick Verano is as follows: Wait for the engine temperature to cool down, allowing the oil to flow back into the oil pan. Use a wrench to loosen the drain plug and place an oil pan underneath to catch the old oil until it stops flowing. Start the engine for about 30 seconds to allow the oil in the main oil passage to drain out. Use a specialized wrench to remove the oil filter. Apply some new oil to the gasket of the new oil filter and tighten it clockwise by hand. Add the new engine oil through the oil filler cap on the engine valve cover. Typically, fill about three-quarters of the oil container. Start the engine and let it run for 5 minutes, then check for any leaks around the drain plug and oil filter. If leaks are found, perform necessary repairs. After stopping the engine, pull out the dipstick to check if the oil level is within the standard range.

What are the differences between the Tiguan and Tiguan L?

Volkswagen launched the Tiguan L in December 2016. The previous Tiguan is referred to as the old Tiguan. The main differences between the two are as follows: 1. Appearance: The old Tiguan is more conservative, while the Tiguan L is more avant-garde; 2. Space: The Tiguan L offers more space than the old Tiguan. 3. Price: The Tiguan L is approximately 15,000 to 30,000 RMB more expensive than the old Tiguan. 4. Configuration: The old Tiguan does not come with a central control display screen. The Tiguan L features a 6.5-inch central control screen, along with USB ports and an SD card slot. Additionally, the Tiguan L includes a keyless start system and engine start-stop technology, which are not available in the old Tiguan. 5. Powertrain: The Tiguan L utilizes a hybrid injection system, which allows for more complete fuel combustion, thereby improving fuel economy. The old Tiguan, on the other hand, is equipped with a turbocharged engine.

Why does the car stall when the clutch is pressed?

When the car stalls upon pressing the clutch, it is because the vehicle encounters certain resistance during idle operation. Depressing the clutch simultaneously disengages the power output between the engine and the transmission. If the clutch is released too quickly afterward, the transmitted power becomes insufficient to move the vehicle, causing the gears to lock up and the engine to stall. Below is relevant information about the clutch: 1. The clutch is located inside the flywheel housing between the engine and the transmission. The clutch assembly is secured to the rear plane of the flywheel with screws, and the output shaft of the clutch serves as the input shaft of the transmission. 2. The clutch is a common component in mechanical transmission systems, allowing the drivetrain to be engaged or disengaged as needed. 3. Installed between the engine and the gearbox, the clutch is the assembly in the automotive drivetrain that directly interfaces with the engine. Typically mounted together with the engine crankshaft's flywheel group, it functions to cut off and transmit power between the engine and the drivetrain. 4. For manual transmission vehicles, the clutch is a critical component of the powertrain, responsible for disconnecting and connecting power to and from the engine.

How Does a Diesel Engine Work?

Diesel engine working principle is as follows: 1. During the intake stroke, the diesel engine inhales pure air. When the compression stroke is completed, diesel fuel is pressurized to over 10MPa by the fuel injection pump and injected into the cylinder through the fuel injector, where it mixes with the high-temperature compressed air in a very short time to form a combustible mixture. 2. Diesel engines have a high compression ratio (generally 16-22). When compression is completed, the air pressure in the cylinder can reach 3.5-4.5MPa, while the temperature can reach 750-1000K (whereas in a gasoline engine at this stage, the mixture pressure would be 0.6-1.2MPa and the temperature would reach 600-700K), significantly exceeding the auto-ignition temperature of diesel. 3. After being injected into the cylinder, the diesel fuel mixes with the air and spontaneously ignites and burns almost immediately. The pressure in the cylinder rapidly rises to 6-9MPa, and the temperature also increases to 2000-2500K. Under the push of the high-pressure gas, the piston moves downward, driving the crankshaft to rotate and perform work. The exhaust gas is then discharged into the atmosphere through the exhaust pipe.
