Where is the engine number of Great Wall Fengjun 5 located?

The engine number of Great Wall Fengjun 5 is located on the engine block, specifically marked on the block to the lower right side of the car's ignition coil. It generally consists of a combination of 7 to 8 digits and letters. In addition to the above method, the engine number can also be checked through the following 4 ways: The vehicle's driving license contains the engine number, usually located on the second-to-last line; The motor vehicle registration certificate will state the engine number; The car purchase invoice will indicate the engine number; The vehicle purchase tax payment certificate will specify the engine number. It's important to note that the engine number is not the same as the engine model. The engine model refers to the specification and size of the engine within the manufacturer's range, and engine models can be the same. The engine number, however, refers to the production number of the engine. Each engine can only have one engine number, and every engine's number is unique.

How to reset the tire pressure on Roewe 360?

There is a tire pressure reset button next to the gear shift lever. Press and hold it to turn off the tire pressure monitoring warning light. Below is some information about tire pressure monitoring: 1. Many cars are equipped with tire pressure monitoring devices. Most tire pressure monitoring systems use wheel speed sensors to monitor the rotation speed of the wheels. When the tire pressure of a certain wheel is abnormal, the rotation speed of that wheel will also be abnormal. The wheel speed sensor can detect this, and the tire pressure monitoring system warning light on the dashboard will illuminate to alert the driver. 2. Tire pressure should not be too high or too low. If the tire pressure is too low, wave deformation may occur during high-speed driving, increasing the risk of a tire blowout. If the tire pressure is too high, it will reduce the contact area between the tire and the ground, thereby reducing grip and affecting handling. When using the car, it is recommended that drivers regularly check their tire pressure and also inspect the tire surface for any damage.

Should the rearview mirror be adjusted to the front door or the rear door?

The left rearview mirror should allow visibility of both the front and rear door handles of the vehicle, as well as the position of the rear wheel fender. The right rearview mirror should be adjusted to the same position to ensure driving safety. The interior rearview mirror should be positioned in the center of the rear window. Position of the central rearview mirror: The ground should occupy half of the view, and the sky should also occupy half. Position of the right rearview mirror: The sky in the right rearview mirror should occupy only a quarter of the view, and the vehicle body should also occupy a quarter. Position of the left rearview mirror: Using the horizon as a reference, the rearview mirror should display an equal split between sky and ground. Then, adjust the left and right angles so that the vehicle body occupies about a quarter of the mirror's surface.

What is the firing order of a domestic six-cylinder engine?

The firing order of an inline 6-cylinder engine is: 1-5-3-6-2-4 or 1-4-2-6-3-5. Here is some relevant information: 1. Firing order: 8, 10, and 12-cylinder engines are generally arranged in a V-configuration, but their firing order is closely related to the crankshaft arrangement. There are many choices for the firing order, which determines the structural form of the crankshaft. 2. Ignition method: It is necessary to consider both uniform ignition intervals and the balance of primary and secondary inertial forces and moments, as well as engine torsional vibration and many other factors. Generally, four-stroke engines with an even number of cylinders per bank use a 360-degree interval angle and cross-firing between the left and right cylinder banks.

What are the classifications of oxygen sensors?

Oxygen sensors can be classified into: standard oxygen sensors, air-fuel ratio sensors, and nitrogen oxide sensors. The automotive oxygen sensor is a critical feedback sensor in the electronic fuel injection engine control system, playing a key role in controlling vehicle exhaust emissions, reducing environmental pollution, and improving the fuel combustion quality of the engine. Below is an introduction to these three types of oxygen sensors: 1. Standard Oxygen Sensor: Automotive oxygen sensors mainly include zirconia and titanium dioxide types. Both types can be further divided into heated and unheated versions, with most vehicles using the heated type. 2. Air-Fuel Ratio Sensor: The air-fuel ratio sensor can continuously measure the air-fuel ratio across the entire range from rich to lean mixtures. Compared to standard oxygen sensors, this type of sensor enables feedback control of the air-fuel ratio throughout the engine's operating range, achieving optimal fuel consumption, emissions, and performance in all conditions. 3. Nitrogen Oxide Sensor: The nitrogen oxide sensor is used to identify and check whether the function of the three-way catalytic converter is normal.

How to Replace the Air Conditioning Filter in Emgrand GL?

Replacing the air conditioning filter in the Geely Emgrand GL involves the following steps: 1. Open the glove box and release the clips on both sides by pulling them with your fingers. 2. Lift the glove box upwards to remove the clips. 3. After lowering the glove box, you will see a black cover plate; press the clips on both sides to remove the cover and expose the air conditioning filter. 4. Take out the old air conditioning filter and replace it with a new one. Below are the functions of the air conditioning filter in the Geely Emgrand GL: 1. It ensures the filter fits tightly against the housing, preventing unfiltered air from entering the cabin. 2. It separates solid impurities such as dust, pollen, and abrasive particles from the air. 3. It adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air, providing strong and long-lasting moisture adsorption.
