What to Do If Your Car Fails the Environmental Protection Test?

If your vehicle fails the environmental protection test three times, the first consideration should be whether there is an issue with the catalytic converter. Car exhaust contains many pollutants, with the primary ones being carbon monoxide, hydrocarbons, and nitrogen oxides. Under normal circumstances, the catalytic converter processes these through oxidation and reduction, converting them into harmless carbon dioxide, nitrogen, and water, thereby achieving purification. The catalytic converter is called a "three-way" catalytic converter because it contains three precious metals: platinum (Pt), rhodium (Rh), and palladium (Pd), hence the name "three-way." Solution: Before the test, drive on the highway for a while to allow the catalytic converter to reach its optimal operating temperature before testing. The most important point is not to turn off the engine before the test, as this keeps the catalytic converter at a certain temperature. If this still doesn't work, directly clean the catalytic converter and then retest to see if it passes. If it still fails, consider the following possible reasons: 1. The oxygen sensor is faulty. Solution: Replace the oxygen sensor. 2. The air filter is problematic. Solution: Replace the air filter. 3. The fuel is the issue. Solution: Add half a tank of E10 ethanol gasoline. Ethanol has a high oxygen content, which aids combustion. If none of these methods work, there is basically no other solution.

What is the one-touch window operation for the Verano?

Operation method for the Verano's one-touch windows: 1. To open the window, press the switch to the first position and hold until the window moves to the desired position, then press slightly harder to the second position, and the window will automatically lower; 2. To close the window, pull the switch to the first position and hold until the window moves to the desired position, then briefly pull the switch to the second position, and the window will automatically close. The Buick Verano is a new compact model from Buick, positioned above the Excelle. In terms of body dimensions, it measures 4718mm in length, 1802mm in width, 1466mm in height, with a wheelbase of 2700mm.

Which vehicles are included in the rural auto promotion program?

The rural auto promotion program generally does not include models such as sedans, SUVs, or MPVs. Only minibuses, light trucks, and motorcycles are covered. The rural auto promotion is a pro-farmer policy proposed by the State Council in 2009, which not only meets the needs of benefiting and strengthening agriculture but also serves as an important measure to stimulate consumption and production. The rural auto promotion not only provides farmers with rural household registration preferential purchase subsidies and tax reductions but also stimulates economic consumption to a certain extent and revitalizes the automotive industry. For example, the Chengdu Wanyou is a vehicle with high ground clearance, low fuel consumption, high quality, low price, and strong load capacity, making it suitable for regional markets. In terms of engine usage, this vehicle is equipped with the 4L88 engine, a brand-new product jointly developed by Changchai and Great Wall, with a displacement of 2.8 liters and a power output of 65kW. It also comes with a PM injection pump and Bosch P injectors from Germany. The engine's fuel consumption rate is significantly reduced, with fuel consumption below 6 liters per 100 kilometers, showcasing outstanding fuel-saving performance. Chengdu Daxingda Auto: Excellent fuel-saving performance, leading in vehicle length and space volume among similar models. Utilizing the latest technology, it achieves excellent fuel-saving performance with a fuel consumption of only 6.25-6.5L per 100 kilometers. Meanwhile, the vehicle length is 3.868 meters, width is 1.528 meters, and height is 1.848 meters.

How to Smooth Out After Applying Touch-Up Paint Pen?

Methods for smoothing out after applying a touch-up paint pen are as follows: 1. Smoothing with wet sandpaper. You can use 2000-grit wet sandpaper for sanding. After the touch-up paint has dried, soak the wet sandpaper in soapy water for 20-30 minutes to make it softer, then sand the uneven paint surface until the thickness of the touch-up matches that of the original factory paint. 2. Smoothing with toothpaste. Toothpaste can serve as a mild abrasive. First, squeeze toothpaste onto a soft, clean towel or sponge, then gently rub the uneven areas until the touch-up paint thickness is level with the original factory paint. 3. For better results, you can also use polishing compound for finishing.

Severe Vibration in Three-Cylinder Engines After Three Years?

Three-cylinder engines vibrate because the moment of inertia cannot ensure balance, leading to jolting. The invention of three-cylinder engines primarily aligns with the trend toward smaller-displacement automotive engines, and today's three-cylinder engine technology has reached a mature stage. The main advantage of three-cylinder engines is their low fuel consumption. Due to their structural benefits, three-cylinder engines excel in fuel consumption control. Engine miniaturization results in a smaller size, higher power density, and improved thermal efficiency. Structural factors also contribute to lower pumping losses in three-cylinder engines. The smaller cylinder block reduces friction losses during operation, and correspondingly, heat dissipation losses are minimized. Powerful performance: Within the 1.0L-1.5L displacement range, three-cylinder engines have fewer cylinders than four-cylinder engines, resulting in larger single-cylinder volume for the same displacement, which delivers better low-speed power. Fewer cylinders mean less mechanical friction, while more cylinders reduce single-cylinder efficiency. Three-cylinder engines exhibit faster dynamic response and stronger performance compared to four-cylinder engines. Reduced turbo lag: Three-cylinder engines experience less exhaust interference than four-cylinder engines. With small-inertia turbo technology, three-cylinder engines achieve better low-end torque and less turbo lag than four-cylinder engines. Compact size and lightweight. Three-cylinder engines are compact and lightweight, which helps reduce overall vehicle weight. Their smaller dimensions also save space in the engine compartment, providing room for electrified components.

How to Identify if a Car is a Stock Vehicle?

Methods to determine if a car is a stock vehicle: 1. Check the car's nameplate, which indicates the manufacturing date. If the time difference between the manufacturing date and the purchase date exceeds six months, it can generally be considered a stock vehicle. 2. There is also a vehicle nameplate in the engine compartment, which will also display the car's production date. 3. Many components of the car, such as headlights, glass, radiator frame, radiator, generator, compressor, tires, etc., have detailed production dates. 4. The production dates of the car's components should all be earlier than the vehicle's production date; otherwise, they have been replaced later. When inspecting the car, owners can check the production dates of the main components.
