The Actual Differences Between China 5 and China 6 Emission Standards

Why is the car safety indicator light always on?

The reasons why the car safety indicator light is always on are as follows: 1. If it is the red light in the upper left corner, it is the oil lamp, indicating insufficient oil. 2. If it is the orange light in the lower corner, it is the engine fault light, indicating that the engine has a fault. 3. If it is the top light on the right side, it is the seat belt warning light, indicating that the passengers in the car have not fastened their seat belts. The bottom light on the right side indicates a battery fault, and the battery needs to be checked. Different safety indicator lights have different handling methods. For example, if the oil is insufficient, it is recommended to check the oil with an oil dipstick. If the oil level is lower than the min on the oil dipstick, then the oil is too low, and you only need to add oil. If the driving time is not very long, but the oil is always decreasing rapidly, then you need to check whether fake oil has been added. If so, it is recommended to replace it with high-quality oil.

What engine does the SAIC Maxus V80 use?

SAIC Maxus V80 uses the Eco-D engine model, with a maximum horsepower of 139 hp, maximum power of 102 KW, maximum power speed of 3500 rpm, and peak torque of 330 Nm. The engine of the SAIC Maxus V80 is produced at the SAIC Diesel Engine Factory in Shanghai, utilizing technology and production lines from the Italian VM Company (one of the world's top six diesel engine manufacturers). For daily maintenance of the SAIC Maxus V80 engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements; Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, causing various problems for the engine. To avoid faults, change the oil regularly based on usage conditions and maintain an appropriate oil level; When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through the filter element, it may burst the filter element or open the safety valve, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal pollution; Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear; Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

How to Pass Subject Two in One Attempt?

The pass rate for Subject Two is relatively low. On the shuttle bus, you often hear people complaining about things like the car being bad or the test site being non-standard, as if the examiners are deliberately failing students. In reality, it's not that serious at all. The cars may vary slightly, but the impact is minimal; the test sites are all standardized. Those who struggle the most (a significant portion being middle-aged women) are the ones who fail repeatedly and complain the most. Don't listen to them. Paying for a trial test will make things clear. Theoretical Basis One: The Three-Point Alignment Principle When your eyes, a specific point on the car body, and a marker on the ground form a straight line, you can determine the car's position. For example, when reversing into the garage, if your eyes see the lower edge of the left rearview mirror aligning with the garage line, it means the car is perfectly in the garage. Why? Because your eyes, the lower edge of the left rearview mirror, and the ground in front of the car form a straight line. Another example: if your eyes align with a red dot (or a node on the windshield wiper, which could be a dot or a square) and the line on the right side of the road, it means the right side of the car is about 30 cm away from the line. Theoretical Basis Two: The Parallel Principle Two parallel lines remain roughly parallel even under weak perspective. Therefore, if the car body in the rearview mirror appears parallel to the line on the ground, it is actually parallel. Looking to the left, if the left side of the car body is parallel to the line on the ground, it means the car body is parallel to the line. Theoretical Basis Three: Control Methods For humans, many controls are based on feeling, but for machines, control algorithms are needed. In automatic control, the essential steps are: setting a reference target position, observing the actual feedback position, comparing them, and executing the control. Car Principle One: Clutch and Gear Shifting The engine and the wheel drive shaft are connected via the clutch. Simplified, the engine keeps rotating while the other end is a wheel, connected by the clutch. The clutch can be seen as a friction plate. When tightly pressed together, the engine and the wheel are firmly connected; if completely separated, they don't affect each other; if slightly pressed, it's half-clutch. The role of half-clutch: when starting, the engine rotates, but the car remains stationary. If the clutch is fully released and the friction plate is pressed hard, the high-speed rotating engine suddenly collides with the stationary drive shaft, causing the engine to stall. Thus, half-clutch acts as a buffer, allowing gradual contact. This applies not only to starting but also to gear shifting. Controlling speed and clutch essentially means controlling the engine's output power. Car Principle Two: Forward and Reverse Driving The vehicle's steering revolves around a point on the rear axle, creating an arc. From the diagram, you'll notice: the front wheels have a larger turning radius than the rear wheels, so in an S-curve, the rear wheels are closer to the inner line while the front wheels are farther away. The steering direction is the same whether moving forward or backward. Turning the steering wheel to the left will make the car veer left, regardless of direction. Calibration As an engineering student, I know calibration is crucial. Calibration means "establishing standards." Only under consistent standards can you use familiar, unchanging methods for precise control. Calibration mainly involves adjusting the seat and rearview mirrors. My calibration method: first, park the car accurately in the garage, ensuring the lower edge of the left rearview mirror aligns with the garage line and both mirrors show the rear garage corners. This means the seat and mirrors are adjusted to "my standard position." How to Adjust the Seat and Rearview Mirrors Use the above calibration method to find the standard position. However, during the exam, you can't adjust like this, so establish five calibration results for adjustment. Park the car in the garage, adjust the seat and mirrors to the best position, then "one press, two stretches": press the clutch, lean your back against the seat, stretch your left arm forward horizontally to rest on the steering wheel's upper edge, and use your right hand to adjust the seat. If the clutch feels comfortable and your left wrist just rests on the steering wheel edge, it's suitable. Then, lean your back against the seat and stretch both arms forward. If both wrists can rest on the steering wheel edge, it's perfect. Otherwise, fine-tune the seatback angle. "Up, Down, Left, Right": First, adjust vertically so the front door handle is in the middle of the rearview mirror, and the rear door handle is just visible. Then, adjust horizontally so the white car body occupies a quarter of the mirror. Repeat adjustments, ensuring your back is always against the seat. Exam Process 1: Reversing into the Garage Secure the seat, fasten the seatbelt, adjust the seat and mirrors, and release the handbrake. Adjust the car's position if the previous test-taker left it in a poor state.

What are the causes of ABS ESC failure?

ABS warning light can indicate various conditions, each with different causes and solutions as follows: Condition 1: ABS warning light stays on (most common). Cause 1: The ABS wheel speed sensor's sensing area is covered by mud, dirt, or other contaminants, affecting its ability to detect wheel speed signals. This prevents the ABS control unit from determining vehicle speed or wheel slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean contaminants from the wheel speed sensor and adjust the gap between the sensor and tone ring to restore normal function. Cause 2: Loose wiring connections or poor ABS relay contact causing signal interference. Solution: Inspect wiring connections and re-secure any loose parts. Condition 2: ABS warning light intermittently illuminates but turns off during acceleration. Cause: Battery voltage drops below 10.5V when multiple electrical components are in use. The light extinguishes when engine speed increases voltage. Possible low system voltage due to poor terminal contact or grounding issues. Solution: Check battery specific gravity; inspect charging system; examine power supply (e.g., voltage relay or loose power connections). Condition 3: ABS light remains on after engine start until ignition OFF. Cause: Poor ground connection at ABS hydraulic valve body; faulty wiring harness connection; ABS control module malfunction. Solution: Loosen and retighten valve body ground screw (clean contact surface if necessary); check connector gaps; replace ABS or ABS/ASR control module. Condition 4: ABS light activates during high-speed driving. Cause: Significant discrepancy between front/rear wheel speed signals detected by ABS module; incorrect tire or wheel specifications. Solution: Verify correct tire/wheel specifications per vehicle placard (typically on fuel filler door). Condition 5: Intermittent ABS warning light activation. Cause: Improper brake light switch adjustment; internal switch contact failure. Solution: With engine running, fully depress brake pedal while manually pushing switch lever downward, then release pedal to reset position; replace brake light switch if needed. When the ABS warning light is illuminated, continued driving is not recommended as it indicates anti-lock braking system malfunction. During emergency braking, wheel lock-up could cause loss of vehicle control, preventing speed reduction or trajectory adjustment, posing significant safety risks.
