Why Does the Car Keep Failing to Start?

Why is water dripping from the Golf's exhaust pipe?

Water dripping from the Golf's exhaust pipe occurs because gasoline, after complete combustion, produces water vapor and carbon dioxide. Water vapor is colorless and transparent at high temperatures, but when the temperature drops below 100 degrees, the water vapor condenses into water. Taking the 2021 Golf as an example, it is a compact car with body dimensions of 4296mm in length, 1788mm in width, and 1471mm in height, a wheelbase of 2636mm, and a fuel tank capacity of 51 liters. The 2021 Golf is equipped with a 1.2T turbocharged engine, delivering a maximum horsepower of 116 PS, a maximum power of 85 kW, and a maximum torque of 200 Nm, paired with a 7-speed dual-clutch transmission.

What transmission is used in the Haval H2?

Haval H2 uses a 6-speed manual and 7-speed dual-clutch transmission. The functions of the transmission are: 1. Change the transmission ratio; 2. Expand the torque and speed of the driving wheel; 3. Enable the car to drive backwards; 4. Facilitate gear shifting or power output. Taking the 2018 Haval H2 as an example, it is a compact SUV with body dimensions of: length 4365mm, width 1814mm, height 1710mm, and a wheelbase of 2560mm. The 2018 Haval H2 is equipped with a 1.5T turbocharged engine, with a maximum horsepower of 150PS, a maximum torque of 210Nm, and a maximum power of 110kW, paired with a 6-speed manual transmission.

What is the manufacturer of the transmission in the Haima 8S?

Haima 8S's transmission is manufactured by Aisin. The functions of the transmission are: 1. To change the transmission ratio to meet the traction needs under different driving conditions; 2. To enable reverse driving; 3. To interrupt power transmission to the drive wheels when the engine starts, idles, the car shifts gears, or needs to stop for power output. Taking the 2020 manual comfort Haima 8S as an example, its body structure is a five-door, five-seat SUV. The body dimensions are: length 4565mm, width 1850mm, height 1682mm, wheelbase 2700mm, front and rear track 1590mm, fuel tank capacity 58l, trunk capacity 552l, and curb weight 1545kg.

How Often Should the Combustion Chamber Be Cleaned?

Automobile combustion chambers are generally cleaned once every 2 years or approximately 40,000 kilometers. Definition: The combustion chamber is a device where fuel or propellant burns to generate high-temperature gas. It is a combustion apparatus made of high-temperature-resistant alloy materials. The space between the top of the piston at top dead center and the cylinder head is where the fuel burns. It is a crucial component of gas turbine engines, ramjet engines, and rocket engines. Composition: The combustion chamber consists of: a diffuser, combustion chamber casing, flame tube, fuel nozzle, and ignition device. Diffuser: The function of the diffuser is to reduce the airflow velocity from the compressor to facilitate combustion organization. Combustion Chamber Casing: The function of the combustion chamber casing is to form a secondary airflow channel. In annular and annular combustion chambers, the casing is composed of inner and outer shells and also serves as the main load-bearing component of the engine. Flame Tube: The flame tube consists of a swirler, flame tube body, and gas conduit. Fuel Nozzle: The function of the fuel nozzle is to atomize the fuel, accelerate the formation of the mixture, ensure stable combustion, and improve combustion efficiency. Ignition Device: The function of the ignition device is to provide the initial ignition torch to the combustion chamber when starting the gas turbine.

Do I Need to Shift to P Gear When Parking for Refueling?

Shifting to P gear is necessary when parking for refueling. Many car models nowadays cannot be turned off without shifting to P gear, which is a safety measure to prevent drivers from forgetting to engage P gear. In essence, P gear is similar to N gear, except that when P gear is engaged, a pawl inside the transmission locks the output shaft, preventing the vehicle from moving. Below are some key points about parking in P gear: 1. Key Point One: It's important to note that the handbrake must be engaged before shifting to P gear. Only the handbrake can truly prevent the car from moving. 2. Key Point Two: The function of P gear is similar to engaging first gear in a manual transmission to prevent rolling. Simply put, when the vehicle is subjected to external force, the handbrake should be engaged first to bear the force. If P gear is engaged first, the transmission bears the force. If the handbrake fails, it's not a big issue as it's easy and inexpensive to repair. However, if the transmission is damaged, it can be quite troublesome. 3. Key Point Three: The transmission of automatic vehicles has a limited capacity to withstand external forces, approximately around 20,000 newtons of pressure. If the driver shifts to P gear before turning off the engine, especially on uneven roads, the vehicle's weight will exert force on the transmission gears due to gravity.

What Does a Car Brake Malfunction Mean?

It indicates that there is a malfunction in the car's braking system. Handbrake Light Stays On: Most vehicles have a brake fluid level warning system, where the brake fluid warning light usually shares the same indicator as the handbrake. Therefore, if the red handbrake light remains on after releasing the handbrake, it is necessary to check if the brake fluid level is low. Some models also input the brake fluid replacement mileage into the vehicle's computer. After driving a certain distance, the onboard computer will prompt the need to replace the brake fluid on the dashboard or multimedia screen. Worn Brake Pads Can Trigger the Brake Warning Light: As brake pads gradually wear down during driving, the piston inside the brake caliper will adjust to compensate for the gap caused by the wear. Since the piston is pushed by the pressure generated by the brake fluid, the adjusted gap increases the internal space of the brake caliper. This extra space needs to be filled by the brake fluid, ultimately causing the fluid level in the brake fluid reservoir to drop. For this issue, you can either top up the brake fluid appropriately or directly replace the brake pads. Leakage in the System: If there is a leak in the brake caliper or brake lines, it can also cause the brake fluid level in the reservoir to drop too low, triggering a warning. In such cases, the leak should be inspected immediately, and repairs or replacements should be made. If the brake pads are contaminated with oil, they must be cleaned thoroughly or replaced directly.
