The solutions to the high fuel consumption of the Excelle are as follows: 1. Clean the engine carbon deposits. Excessive carbon deposits in the engine are a major cause, primarily due to the use of unsuitable fuel. It is recommended to add a certain amount of cleaning agent when refueling. If the effect is not noticeable, it indicates a significant amount of carbon deposits in the engine. In this case, the car must be taken to a 4S shop for professional technicians to clean the carbon deposits inside the engine. After cleaning, it is advisable to drive the car at high speed for a while, which helps increase exhaust flow and allows stronger airflow to remove larger carbon particles. 2. Check the oxygen sensor. As an internal control unit of the car, the oxygen sensor mainly monitors the fuel-air ratio in the engine. Once it is damaged, it will cause an imbalance in the fuel-air ratio, leading to a sudden increase in fuel consumption. When the oxygen sensor is damaged, the exhaust pipe will emit darker-colored exhaust gas during driving, and the oxygen sensor should be replaced at this time. 3. Regularly replace the three filters. During the use of the vehicle, the oil filter, air filter, and fuel filter must be replaced regularly. If they are not replaced for a long time, they will become dirty and send incorrect information to the engine control unit, resulting in incomplete fuel combustion and increased carbon deposits in the engine. 4. Check the electronic control unit. Although the engine's electronic control unit is highly reliable, in vehicles with longer service life, various faults are inevitable. For example, problems with the engine control unit will directly lead to difficulties in starting, increased fuel consumption, poor power performance, and thick black exhaust gas.

What Does Car Torque Mean?

Car torque is the rotational force output from the crankshaft of an engine. Here are more details about car torque: 1. With a fixed power output, car torque is inversely proportional to engine speed. The faster the speed, the smaller the torque, and vice versa, reflecting the vehicle's load capacity within a certain range. 2. The greater the torque output, the higher the vehicle's carrying capacity. It also means better acceleration performance and stronger climbing ability. This results in fewer gear shifts and relatively less wear on the transmission. During startup, the advantages of higher torque become even more apparent.

What is the difference between a regular car battery and a start-stop battery?

There are several main differences between regular car batteries and start-stop batteries: 1. Start-stop batteries can be used more times and have a longer lifespan than regular batteries. Their plates are harder than regular plates, and the active material is less prone to falling off, making them suitable for vehicles with start-stop mode. 2. Start-stop batteries are manufactured using stamping processes due to higher technical requirements, but they have larger capacities and can charge and discharge quickly. Ordinary lead-acid batteries cannot discharge large currents multiple times in a short period, as their separators do not allow ions to pass through quickly. 3. The conditions for start-stop engine shutdown are very strict: low battery charge, low air temperature, low water temperature, fog lights on, distance from last activation to current parking less than 300 meters, or engine speed not reaching above 1800 rpm from last activation to current parking. If these conditions are not met, the engine will not shut down.

Abnormal Noise Fault Phenomena and Causes in the Drive Axle

Abnormal noise fault phenomena in the drive axle: 1. Abnormal noise occurs in the drive axle while driving, which weakens or disappears when coasting in neutral. 2. Abnormal noise occurs in the drive axle both while driving and coasting in neutral. 3. No abnormal noise occurs when the car is driving straight, but abnormal noise appears in the drive axle when turning. 4. Abnormal noise occurs in the rear drive when going uphill or downhill, or in the drive axle during both uphill and downhill driving. 5. There is operational noise or heavy abnormal noise from the wheels. Fault causes: 1. Excessive meshing clearance of the conical and cylindrical main and driven gears, planetary gears, or half-shaft gears; loose fit between the half-shaft gear spline groove and the half-shaft; poor meshing of the main and driven conical gears; uneven meshing clearance of the conical and cylindrical main and driven gears; gear tooth surface damage or broken teeth. 2. Loose main conical gear bearing; loose main cylindrical gear bearing; loose differential conical roller bearing; excessive preload in a rear axle bearing leading to insufficient clearance; improper adjustment of main and driven conical gears, resulting in insufficient clearance. 3. Mismatch between differential planetary gears and half-shaft gears, causing poor meshing; worn or broken planetary gears or half-shaft gears; worn differential cross shaft journal; thinned planetary gear support washer; planetary gears sticking to the differential cross shaft or improper assembly (e.g., excessively thick planetary gear support washer), making planetary gear rotation difficult; loose fastening rivets between the reducer driven gear and the differential housing. 4. Insufficient gear meshing clearance in a certain part of the drive axle, causing noise when going uphill; excessive gear meshing clearance in a certain part of the rear axle, causing noise when going downhill; improper gear meshing marks or loose gear shaft support bearings in a certain part of the rear axle, causing noise during both uphill and downhill driving. 5. Damaged wheel hub bearing or loose bearing outer ring; foreign objects inside the brake drum; broken wheel hub; excessively worn wheel hub bolt holes, leading to insecure wheel rim fixation.

What do the symbols on the car display panel represent?

Automotive instrument panels are divided into the tachometer, odometer, and fuel gauge. Within the entire instrument panel, an indicator light may illuminate at any time. Automotive instrument panel indicator lights are categorized into the following three types: 1. Common driving indicators. Examples include light signal indicators, turn signal indicators, parking lights, etc. Their purpose is to alert the driver to the status of various vehicle functions. 2. Warning lights, which serve an alert function. Examples include the fuel indicator light, door status indicator light, seat belt indicator light, etc. Generally, warning lights turn off after the driver performs the corresponding action, such as the seat belt indicator light extinguishing once the driver fastens the seat belt. 3. Malfunction indicator lights, which are the most critical indicators. Examples include the generator malfunction indicator light, ABS malfunction indicator light, transmission malfunction indicator light, etc. Typically, these malfunction indicator lights rarely illuminate under normal circumstances, or they may light up briefly when starting the engine before turning off. If a malfunction indicator light remains illuminated and is accompanied by a warning sound, it indicates that the vehicle has developed a fault or abnormality. Never underestimate malfunction indicator lights; ignoring them could potentially damage the vehicle and seriously compromise driving safety. If a malfunction indicator light remains on, immediate inspection and repair are necessary.
