What is the wheelbase of the Lavida?

The front wheelbase of the Lavida is 1517 mm, and the rear wheelbase is 1493 mm. Introduction to Wheelbase: Wheelbase refers to the distance between the center lines of the tracks left by the wheels on the vehicle's supporting plane (generally the ground). If there are dual wheels at both ends of the axle, the wheelbase is the distance between the center planes of the dual wheels. Generally speaking, the wider the wheelbase, the higher the driving comfort. Function of Wheelbase: Generally, a wider wheelbase provides higher driving comfort and better stability. When the vehicle tilts laterally, the outer wheels can offer better support. In curves, the vehicle's roll angle is smaller, and the limit of the outer wheels appears later. However, some domestic cars lack power steering, and if the front wheelbase is too wide, the steering wheel can feel very 'heavy,' affecting driving comfort. Additionally, wheelbase also influences the vehicle's total width, total weight, and safety.

What are the reasons for oil leakage in the Audi Q7 4.2 engine?

Audi Q7 engine oil leakage and smoke emission reasons are as follows: Aging and hardening of sealing rings: Over 90 percent of oil leakage problems are caused by rubber sealing rings losing a large amount of plasticizers and softeners due to prolonged exposure to alternating cold and warm temperatures, leading to corrosion, aging, and hardening. Incomplete combustion: Small injection advance angle, incomplete combustion, slight water leakage in the cylinder liner, water content in the fuel, white smoke emission during cold starts, which disappears as the engine temperature rises. Smoke limiter failure: Air-fuel ratio imbalance, decreased cylinder pressure, premature injection timing, failure of the smoke limiter on the injection pump, malfunction of the exhaust brake system, engine cylinder liner wear, stuck rings, misalignment, aging and deformation of valve sealing rings, excessive valve guide clearance.

How to Start a Volvo XC90 When the Key Fob Battery is Dead?

Volvo XC90 vehicles are equipped with an induction area near the steering column, glove compartment, and ignition button. When the key fob battery is dead, you can place the key close to the induction area and then press the start button to attempt starting the vehicle. If it doesn't work on the first try, adjust the key's position near the induction area and try a few more times. 1. The keyless start system utilizes radio frequency identification (RFID) technology. The chip in the smart card automatically senses and controls the door locks. When the driver approaches the vehicle within a certain distance, the door locks will automatically unlock and deactivate the anti-theft system. When the driver leaves the vehicle, the door locks will automatically lock and activate the anti-theft system. 2. Vehicles equipped with a keyless system generally have both an induction system and a key slot. This is to ensure that if the smart card is damaged or the battery dies, the owner can still unlock the doors using the traditional method.

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.
