Where is the Roewe 750 cabin air filter located and how to replace it?

Roewe 750 cabin air filter is located behind the glove box on the passenger side. If you need to replace the cabin air filter, the recommended steps are as follows: 1. Pull out the two clips at the bottom of the glove box and remove the glove box. 2. Unscrew the nut, forcefully remove the upper part of the glove box, and you will see the exterior of the cabin air filter. 3. Open the box, replace the cabin air filter, reinstall the box, and reassemble the glove box in the reverse order of removal. The replacement of the cabin air filter is now complete. Note: There are two types of cabin air filters, one without activated carbon and another with activated carbon. The activated carbon cabin air filter not only has the aforementioned functions but also absorbs a large amount of odors and other effects.

Under What Circumstances Should Spark Plugs Be Replaced?

Replacement of spark plugs is necessary under the following conditions: difficulty in cold-starting the vehicle requiring a second attempt; unexplained engine stalling; difficulty in cold-starting accompanied by vehicle shaking; and engine slipping, among others. Difficulty in Second Start Attempt: Generally, if a car suddenly stalls while driving and becomes difficult to restart, this indicates a significant issue with the spark plugs. If this occurs on a highway, the consequences could be dire. Unexplained Engine Stalling: A normally functioning car starts easily and does not stall without reason. If such a problem arises, it is highly likely that the spark plugs are damaged. In such cases, avoid starting the vehicle and promptly inspect and troubleshoot. If the issue is indeed with the spark plugs, replace them as soon as possible. Difficulty in Cold-Starting and Shaking: If the car requires multiple attempts to start in the morning and stalls after severe shaking even after starting, this is a sign that the spark plugs are not functioning properly. If no other issues are found with the vehicle, it is essentially time to replace the spark plugs. Engine Slipping: During driving, if the car exhibits slipping when changing gears, this indicates insufficient power, accompanied by increased fuel consumption and black smoke from the exhaust pipe. At this stage, the spark plugs are severely worn and must be replaced immediately. Hazards of Not Replacing Spark Plugs Timely: Failing to replace spark plugs on schedule can lead to a sharp increase in fuel consumption during certain periods. As spark plugs age, carbon deposits form on the center electrode, affecting their ignition efficiency and further increasing fuel consumption. Additionally, the lifespan of the car's engine may be compromised. Poor ignition from worn spark plugs results in incomplete combustion of the air-fuel mixture, potentially causing engine cylinder scuffing, which in turn leads to vehicle shaking and excessive engine load, among other irreversible issues. Regular replacement of spark plugs helps extend the engine's lifespan. Precautions for Replacing Spark Plugs: When removing the high-voltage cable, avoid using excessive force or shaking the spark plug insulator, as this can damage the spark plug's performance. Ensure the engine is completely cooled before opening the engine cover, and take care to prevent external oil or dirt from entering the cylinder. Keep the spark plug electrodes and sealing washers clean to avoid safety hazards such as gas or electrical leaks. During installation, align the socket properly and slowly screw in the spark plug. After reaching half the length, tighten it firmly. Always follow the principle of vertical installation and removal to tighten the spark plugs; otherwise, gas leaks may occur.

What are the steps to start an automatic transmission car with one-button start?

First, ensure the key is inside the car, press the brake—hold the start button to start the vehicle, shift to D gear, release the handbrake, and release the brake to start moving. Steps to start an automatic transmission car with one-button start: Step 1: After the driver sits in the driver's seat, there's no need to press the brake, just press the start button once. At this point, the ACC light will turn on. Press it again, and the vehicle will perform a self-check. Step 2: Press the brake and then press the start button to ignite and start the engine. Step 3: Release the foot brake. You can choose to warm up the car in place, with the duration depending on the environment. Step 4: Press the foot brake again, shift to D gear, and release the handbrake. Step 5: Slowly release the foot brake to start moving. Step 6: Depending on road conditions, smoothly press the accelerator to increase speed and drive safely.

Can an Inter-Axle Differential Lock Turn?

An inter-axle differential lock can turn. Depending on the locking method, differential locks can be categorized into: 1. Forced Locking Type: This type of differential lock is set on a common symmetrical bevel gear differential. It has a simple structure, is easy to manufacture, and has a high torque distribution ratio. 2. High-Friction Self-Locking Type: This includes structures like friction plate type and slider cam type. The friction plate type locks the differential through the frictional torque generated when the friction plates slide relative to each other. 3. Jaw Type: The jaw type is commonly used in medium and heavy-duty trucks. 4. Torsen Type: The Torsen differential is a new type of inter-axle differential. It has a wide and adjustable torque transmission range, making it widely used in the central differential of all-wheel-drive cars and the inter-wheel differential of rear-drive axles. 5. Viscous Coupling Type: Some four-wheel-drive cars use a viscous coupling as a differential. Silicone oil has a high thermal expansion coefficient. When the speed difference between the two axles is too large, the temperature of the silicone oil rises sharply, and its volume expands continuously. The silicone oil pushes the friction blades to tightly combine, directly connecting the drive shafts at both ends of the viscous coupler as one, i.e., the viscous coupler locks.

Where is the engine number of Dongfeng Citroen C-Quatre located?

Dongfeng Citroen C-Quatre's engine number is located in the engine compartment of the car, on the right side of the aluminum shell at the front of the cylinder block. The Citroen C-Quatre comes with two types of engines: one is the 1.6-liter TU5JP4 high-performance engine, and the other is the 2.0-liter EW10A engine. The main parameters of these two engines are detailed below: 1. TU5JP4 engine: The TU5JP4 engine has a displacement of 1.6 liters, uses DOHC double overhead camshaft technology, and is fuel-efficient. In terms of power, the TU5JP4 engine has a maximum horsepower of 117 hp, a maximum power of 86 kW, and a maximum torque of 150 N·m. 2. EW10A engine: The EW10A is an improved version of the EW10J4 engine from the PSA Group, featuring a variable valve timing system. In terms of power, the EW10A engine has a maximum power of 103 kW and a maximum torque of 200 N·m. Due to the relatively high compression ratio of the EW10A engine, reaching 11.02, it requires the use of 95-octane gasoline.

What is the horsepower of the Trumpchi GA6?

The Trumpchi GA6 is equipped with an engine that delivers a maximum horsepower of 169 hp. The detailed parameter configuration of the Trumpchi GA6 is as follows: 1. Power data: This model offers one powertrain option, featuring a 1.5T turbocharged engine. This engine has a maximum power output of 124 kW and a maximum torque of 265 Nm. In terms of the transmission system, it is paired with a 6-speed automatic transmission. 2. Engine production: The engine used in this model is independently developed by GAC Trumpchi. It incorporates the latest low-inertia electronically controlled turbocharger, GCCS combustion control patented technology, and DCVVT dual continuous variable valve timing mechanism. Thanks to these advanced production technologies, the engine not only enhances power performance but also improves fuel efficiency. These cutting-edge technologies also help mitigate turbo lag to a certain extent. 3. Turbocharger: The turbocharger used in the engine has a turbine wheel diameter of 37 mm. Compared to traditional turbocharged engines, the turbine inertia is reduced by over 30%, allowing the turbo to engage earlier during engine operation.
