What does maxac and ac air conditioning mean?

maxac is the maximum cooling mode of the air conditioning, and ac is the switch for the car air conditioning cooling mode. Once turned on, the air conditioning can cool. Below are the relevant explanations: 1. The cooling principle of car air conditioning is that after pressing the ac button, the compressor clutch will engage, and the engine will drive the compressor to operate. The compressor continuously compresses the refrigerant and delivers it to the evaporator. The refrigerant can cool the evaporator, and the evaporator can cool the air blown by the blower, so the air conditioning vents can blow out cold air. 2. The heating principle of the air conditioning is that when the heating function is turned on, there is no need to press the ac button, and the compressor does not need to operate when using the heating. When the air conditioning is heating, the high-temperature coolant from the engine flows through the heater core, and then the air blown by the blower passes through the heater core, so the air conditioning vents can blow out warm air.

Does the 4S warranty cover scratches on a new car?

Scratches on a new car are not covered by the 4S warranty because they are caused by human factors and are not related to vehicle quality issues, thus falling outside the warranty scope. However, you can file an insurance claim, have the assessor evaluate the damage, and then proceed with repairs. This helps avoid unnecessary repair costs that may not be reimbursable. Precautions for using a new car include: 1. Warm up the engine before starting; 2. Change the gear oil after driving 2,000 kilometers and pay attention to vehicle maintenance; 3. Control the engine speed during the break-in period to prevent damage from excessive RPM; 4. Get comprehensive insurance and install a dashcam to avoid unnecessary disputes and losses; 5. Avoid sudden acceleration or deceleration to prevent damage to vehicle components.

What is the usage method of fuel injector cleaner?

The usage method of fuel injector cleaner is: 1. Start the engine and warm it up until the cooling fan activates, then turn off the engine; 2. Locate the engine's fuel inlet and return pipes, disconnect the inlet pipe, and block the return pipe; 3. Remove the vacuum hose at the top of the fuel pressure regulator and install the pressure cleaning tank; 4. Use connecting hoses and transition joints to link the special fuel with the main fuel supply pipe, and disconnect the original vehicle's electric fuel pump power circuit; 5. Turn on the ignition switch, start the engine, and let it run until the fuel injector cleaner is completely consumed and the engine automatically shuts off (this process takes about 10 minutes), completing the cleaning of all fuel injectors; 6. Reverse the installation steps to remove the pressure cleaning tank, detached connectors, gauges, connecting pipes, reconnect the fuel inlet pipe and vacuum valve, reconnect the fuel pump circuit, and restore the vehicle's original fuel supply state.

What is the typical idle speed when starting a sedan?

The idle speed for a sedan with a four-cylinder engine is generally around 800 RPM, while for six-cylinder and above models, it is approximately 600 RPM. However, the idle speed is not fixed and can vary depending on factors such as engine temperature and load. For example, when the engine temperature is low, the RPM may increase to ensure smooth operation and to quickly reach the optimal working temperature. As the engine warms up, the idle speed gradually returns to the normal value. An engine is a machine that converts other forms of energy into mechanical energy. Solutions for excessively high RPM include: 1. Adjusting the throttle opening; 2. Replacing the fuel injector, air conditioning clutch, engine, or transmission; 3. Adjusting the intake system; 4. Adding the appropriate engine oil.

What are the signs of timing chain failure in the EA111 engine?

Signs of timing chain failure in the EA111 engine include unusual engine noises, insufficient engine power, excessive fuel consumption, and difficulty starting the vehicle. Below is relevant information about the timing chain: 1. The timing chain is highly reliable and typically functions normally for up to 150,000 kilometers. When the timing chain wears out or stretches, the engine control system will illuminate the engine fault light on the dashboard, indicating a fault in the engine system that requires prompt inspection and repair. 2. The lifespan of the timing chain is also closely related to driving habits, such as frequent sudden acceleration and deceleration. These actions place greater stress on the chain, accelerating wear and reducing its service life. 3. From a professional standpoint, it is essential to visit a repair facility to check whether the engine chain has stretched using a vehicle diagnostic tool. The ignition timing angle can be detected through the engine's data stream, and the number of teeth on the chain tensioner can also be manually inspected to determine if the chain has stretched.
