The reasons why the car won't start are: 1. Battery damage: If this is the reason, it needs to be sent to a repair shop for detection by professional computer equipment. In addition, it may also be due to battery depletion. If you often drive at low speeds in the city and frequently use devices such as headlights, air conditioning, and audio, battery depletion may occur; 2. Abnormal air-fuel mixture in the car: This phenomenon occurs when the throttle or idle speed motor is too dirty. If the valve is too dirty, fuel will spray onto the back and be absorbed by carbon deposits; 3. Unstable power supply voltage of the ignition system: In winter, the car's starting resistance is high, including insufficient battery power, which leads to insufficient voltage in the entire ignition system.

I've encountered the issue of a car not starting several times, mostly due to battery problems, such as an aging battery or forgetting to turn off the lights, which drains the power. When trying to start, you only hear a clicking sound but the engine doesn't turn over. If the battery is fine, it could be a starter motor failure, where the motor doesn't spin. The fuel system also needs to be checked—running out of fuel or a faulty fuel pump can show fuel on the gauge but fail to supply it. The ignition system, like dirty spark plugs or a bad coil, can prevent the engine from firing. Other minor issues include the anti-theft lock activating the car key or the automatic transmission not being in the P position. For safety, avoid repeatedly trying to force-start the car, as it may damage more parts. First, simply check if the battery terminals are loose or corroded. If that doesn't work, seek professional repair. Regular maintenance checks on these components can help prevent issues.

What does 1.5L naturally aspirated engine equate to in turbocharged terms?

1.5L naturally aspirated engine is equivalent to 1T. Below is an introduction to turbocharging: The main function of turbocharging is to increase the engine's air intake, thereby enhancing the engine's power and torque, making the car more powerful. After installing a turbocharger, an engine's maximum power can increase by 40% or more compared to when it is not equipped with one. A 1.4T car's power may be equivalent to that of a 2.0L naturally aspirated car. A turbocharger is essentially an air compressor that increases the engine's air intake by compressing air. It utilizes the inertial force of the exhaust gases expelled by the engine to drive the turbine in the turbine chamber, which in turn drives the coaxial impeller. The impeller then pressurizes the air delivered through the air filter pipeline, forcing it into the cylinders under increased pressure.

What is the reason why the A4L rearview mirror cannot open automatically?

The following are related solutions for the A4L rearview mirror not opening automatically: 1. Test the rearview mirror's operation: Have someone assist by operating the rearview mirror switch inside the car while you place your hand on the mirror to feel if the motor inside is working; 2. Gear damage: If you feel the motor's vibration but the mirror does not move, it indicates that the opening/closing gear mechanism is damaged; 3. Motor failure or wiring issue: If you do not feel the motor's vibration, even after tapping it a few times, it suggests a motor failure or wiring problem, with wiring issues typically being a damaged switch or a blown fuse. 4. Check the fuse and switch: First, inspect the fuse for the rearview mirror folding circuit. If the fuse is fine, the issue is likely a faulty switch. Sometimes, extremely low temperatures or dust buildup in the extension mechanism can increase resistance, preventing the mirror from opening. In such cases, manually assisting the mirror to open might help resolve the issue.

Differences between Baojun Valli and RC-5W?

There are many differences between Baojun Valli and RC-5W. Here are the specific details: 1. Space Experience: A station wagon is not an SUV; it is still a sedan, but with double the trunk space compared to a regular sedan. Essentially, there is no difference for passengers, and it does not have an advantage over SUVs. Clearly, even compared to sedans, the RC-5W is not particularly large, just average, but sufficient for daily use. 2. Vehicle Power: This is the biggest difference between the new Baojun Valli and RC-5W. The Valli has eliminated the 1.5L naturally aspirated model, retaining only the 1.5T model, but it still offers a manual transmission. The manual transmission in the RC-5 display car has clear gear shifts, strong suction feel, and is full of driving pleasure. The engine is the legacy LJO engine, with a maximum horsepower of 147 HP and a maximum torque of 250 Nm, reaching peak torque at 2200-3400 RPM. The acceleration test for the RC-5W's 1.5T model shows a 0-100 km/h time of around 9 seconds.

Can You Still Drive with a Damaged Transmission Valve Body?

You should not continue driving the car after the transmission valve body is damaged. Here are more related details: Cause Analysis: 1. A damaged transmission valve body may experience jamming. If leakage occurs, it can cause gear shift shocks during the transmission's shifting process, significantly reducing shifting efficiency and also leading to a decrease in the car's power. 2. The transmission valve body is a hydraulic control unit. During operation, the spools on the valve body move left and right to change the direction and pressure of the hydraulic oil, enabling the transmission to shift automatically. If the valve body is damaged, jamming or leakage can cause gear shift shocks. It's worth noting that the spools on the valve body are controlled by the electronic control unit via solenoid valves. 3. Damage to the transmission valve body is more common in automatic transmissions. Automatic transmissions, as opposed to manual transmissions, allow the car to shift gears automatically based on driving speed and engine RPM. Currently, the most common types of automatic transmissions used in cars are hydraulic automatic transmissions (AT), continuously variable transmissions (CVT), automated manual transmissions (AMT), and dual-clutch transmissions.

Is the Mercedes-AMG C43 Considered a Genuine AMG?

Yes, it is an AMG. Below is a detailed introduction about the Mercedes-AMG C43: 1. Exterior: The car features 19-inch light-alloy multi-spoke wheels with a matte black finish and silver outer edges, exuding a strong sporty vibe. This design is commonly seen in many AMG models, including Porsche variants. The front 4-piston and rear 1-piston brake calipers, paired with larger perforated brake discs, provide ample confidence. The tires are Michelin PS4S all-season tires, balancing aggressive driving and daily use, perfectly aligning with the car's positioning. 2. Interior: Despite being a performance car, the A35L also excels in creating an interior ambiance that blends sportiness and luxury. The steering wheel adopts an AMG-exclusive design, with the AMG logo engraved at the bottom. The AMG emblem on the welcome sill reminds you the moment you open the door that this is an AMG. The metal trim panel that runs across the dashboard extends to the doors, adding a cool, sophisticated element to the car's interior.
