Is the Emgrand GS engine equipped with a belt or chain?

The Emgrand GS engine uses a timing chain. Structure of the timing chain lubrication oil passage in the engine: It includes the engine block and oil passages. The front end face of the block is equipped with an oil nozzle. Inside the engine block, there are a short oil passage, a main bearing lubrication oil passage, and the engine main oil passage. The oil nozzle is positioned above the timing chain and is connected to the main bearing lubrication oil passage via the short oil passage. The other end of the main bearing lubrication oil passage connects to the engine main oil passage. Distance between the oil nozzle and the timing chain: The oil nozzle is close to the timing chain, allowing lubricating oil to be directly sprayed onto the timing chain, ensuring simple and reliable lubrication. The lubrication oil passage connected to the oil nozzle is short in length and close to the main oil passage, resulting in minimal oil pressure loss. This setup ensures higher oil pressure for the lubricating oil, guaranteeing that the timing chain receives sufficient, stable, and timely cooling and lubrication during operation.

What is the method for testing engine cylinder pressure?

Testing engine cylinder pressure involves the following steps: 1. Warm up the engine and then shut it down; 2. Remove all high-voltage wires; 3. Use cylinder compression pressure to expel spark debris; 4. Remove all spark plugs; 5. With the throttle fully open, rotate the engine crankshaft to take measurements. Precautions for testing engine cylinder pressure include: 1. Ensure the battery is fully charged and the starter is in good technical condition; 2. The engine's cooling temperature should be within the specified range; 3. The engine's lubrication conditions should be optimal; 4. When measuring each cylinder's pressure, ensure the compression stroke occurs at least 4 times; 5. During testing, stay clear of external moving parts and hot areas of the engine; 6. When removing or installing engine spark plugs, take care to prevent foreign objects from entering the engine interior.

Should I Drive at High Speed First or Get the First Maintenance First?

Drive at high speed before the first maintenance. The break-in period for a new car is generally around 2,000 kilometers. Under normal circumstances, it is necessary to drive at high speed to allow the engine to fully operate, usually not exceeding two-thirds of the maximum speed, and maintain a steady speed for more than 10 minutes before coasting in neutral until the car stops. Before getting the first maintenance, pay attention to the following points: 1. Make an appointment in advance: It is best to make an appointment with the 4S shop first, otherwise, you might encounter situations where there are no available service bays or long waiting times. 2. Bring necessary documents: When going for the first maintenance, bring essential items such as the maintenance manual and vehicle registration. If unsure about which documents to bring, clarify this when making the appointment. 3. Record issues promptly: If you encounter any faults or questions while driving, note them down and inform the staff during the first maintenance registration so that the technician can inspect all issues during the first maintenance.

What are the reasons for the weak air conditioning airflow in Geely Emgrand?

The reasons for the weak air conditioning airflow in Geely Emgrand are as follows: Airflow direction selection issue: Check if the car's air conditioning airflow direction is incorrectly set. If the airflow is directed towards the front windshield or side windows, it may feel like the airflow entering the cabin is weak. Blower motor malfunction: A faulty blower motor can result in reduced airflow from the air conditioning vents. If the blower motor experiences a short circuit or power loss, the air volume delivered by the car's air conditioning system will naturally decrease. If the issue lies with the blower motor, it is recommended to have it inspected and repaired by a professional service center, as this is not a problem that can be fixed by the owner. Air filter problem: A dirty air filter can obstruct the airflow from the air conditioning system. The air filter is designed to remove impurities from the air entering the cabin. If too many impurities accumulate, it will affect the airflow volume from the vents.
