Can a Waterlogged Three-Way Catalytic Converter Still Be Used?

A waterlogged three-way catalytic converter can still be used. Here is some information about three-way catalytic converters: 1. Three-way catalytic converter: It refers to a catalytic device that converts harmful gases such as CO, HC, and NOx emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. 2. Substrate: The main component is the three-way catalytic converter, whose substrate is a porous ceramic material installed in a specially designed exhaust pipe. Precautions for using a three-way catalytic converter are as follows: 1. Damage: If the three-way catalytic converter has mechanical damage, thermal sintering, has exceeded 200,000 kilometers in mileage, or suffers from lead poisoning, cleaning will be of little use. 2. Cleaning the three-way catalytic converter: This should be done after cleaning the throttle valve, fuel injectors, and combustion chamber. 3. During cleaning: The idle speed should not be too high to avoid overheating the three-way catalytic converter. 4. Safety: The work area should be kept away from fire sources, and appropriate fire prevention measures should be taken.

Where to Turn on the Turn Signal in Subject 2?

In Subject 2, the turn signal should be turned on in the following situations: 1. When exiting the parallel parking space, the left turn signal should be activated; 2. Before starting on a slope, the left turn signal should be turned on; 3. During a right-angle turn, the left turn signal should be used; 4. Before starting on an electronic road surface, the turn signal should be activated. The turn signal is an important indicator light that is turned on when a motor vehicle changes direction to alert surrounding vehicles and pedestrians. The turn signal tube uses a xenon tube, controlled by a single-chip circuit, with alternating left and right flashing for continuous operation. The turn signal uses a flasher to achieve the blinking effect, which can mainly be divided into three types: resistance wire type, capacitor type, and electronic type. The timing for turning on the turn signal should be well managed; it should be activated about 100 meters before the turn. If changing lanes, the signal should be turned on in advance.

How to Operate Remote Start on CT5?

First press the lock button on the key, then immediately press the button with an arrow to start. The APP has no distance limitation, while the key works within 60 meters. The car will start automatically in about 4 seconds. Remote start of the engine or motor means activating the engine or motor via the remote key. Below is extended information about the remote key: 1. Principle: The vehicle starts the engine or motor based on signals received from the remote key. This entire process eliminates the inconvenience of manually entering the car to operate. While the engine or motor is running, the central locking system remains in the locked state, providing effective security. 2. Features of Remote Start: (1) High Reliability: Since there is no structural difference between remote start and manual ignition inside the vehicle, there is no mechanical wear issue with the heater, significantly reducing the likelihood of failure. (2) Convenience: Although remote start cannot be timed like parking heaters, the remote start method is still very convenient. The remote range is typically no less than 50 meters, allowing you to start the engine or motor in advance from home or the office if the car is parked in a ground-level parking lot. (3) Automatic Timing: Usually, if no operation is performed within a certain period after remote start, the engine or motor will automatically shut down to avoid fuel waste caused by forgetting to turn it off.

Can a BMW still be driven if the DSC fails?

BMW can still be driven if the DSC fails. The failure of BMW DSC means the failure of the vehicle stability system, which can be detected and repaired at a service station using a computer. DSC stands for Dynamic Stability Control, which is an extension of the traction control system. It ensures the best traction when the car is turning to maintain driving stability. Here is some extended information about DSC: 1. The functions of DSC are as follows: (1) When emergency braking, ABS prevents the wheels from locking; when the wheels slip, TCS controls the engine output and wheel braking to prevent wheel slip. (2) The vehicle stability control system uses computer control to manage engine output and braking of any wheel (with varying braking force) when the vehicle understeers and slides outward, or oversteers and crosses the centerline of the road or even spins in place during quick turns, evasive maneuvers, or avoiding suddenly appearing cars or animals. 2. The causes of DSC failure are as follows: (1) Wheel speed sensor failure. (2) Wheel speed sensor signal disc failure. (3) Steering angle sensor failure. (4) Steering gear failure, etc.

What is the correct procedure when a vehicle rolls over?

When a vehicle suddenly rolls over, the driver should firmly grip the steering wheel with both hands, hook their feet onto the pedals, and press their back tightly against the seat backrest to stabilize their body and avoid injuries from impacts inside the vehicle. Additionally, care should be taken to prevent being crushed due to vehicle deformation. If the vehicle continues rolling into a deep ditch, the driver should quickly move their body to the lower front of the seat, hold onto the steering wheel or other stable parts to secure themselves, and avoid injury from rolling. Below are some driving precautions: 1. Check mirrors: Always use turn signals and slow down when turning or changing lanes; always check the mirrors before turning. Left turns primarily require checking the left mirror, right turns the right mirror, and both turns should involve checking the interior rearview mirror. 2. Avoid fixating on the front of the vehicle: When driving on clear roads, look straight ahead about 100 meters, not just at the immediate front of the vehicle. 3. Depress the clutch: Generally, when decelerating at speeds above 40 km/h, there's no need to depress the clutch immediately; wait until the speed drops to around 20 km/h before doing so. 4. Steering: Turn the wheel slowly for high-speed turns and quickly for low-speed turns.

What are the new regulations for annual inspection of family 7-seater vehicles?

New regulations for vehicle annual inspection: Starting from November 20, 2020, non-operational small and mini passenger vehicles with 7-9 seats (excluding minivans) within 6 years are included in the exemption range; for non-operational small and mini passenger vehicles (excluding minivans) over 6 years but under 10 years, the inspection cycle is relaxed from once a year to once every two years, meaning private cars only need to undergo on-site inspections twice within 10 years, specifically in the 6th and 8th years. Content of the annual inspection: Check whether the engine, chassis, body, and their auxiliary equipment are clean, complete, and effective, whether the paint surface is uniform and aesthetically pleasing, whether the main assemblies have been replaced, and whether they match the initial inspection records; Test whether the vehicle's braking performance, steering control, lights, exhaust, and other safety performance meet the requirements of the "Technical Conditions for Safe Operation of Motor Vehicles"; Check whether the vehicle has been modified, remodeled, or altered, whether the driving license, license plate, and all records in the vehicle file match the actual condition of the vehicle, whether there are any changes, and whether the approval and alteration procedures have been completed; Check whether the license plate, driving license, and the enlarged license plate characters printed on the vehicle are damaged, altered, or unclear, and whether they need to be replaced; Check whether large vehicles have the unit name or the name of the street, township, or town where the vehicle is located and the maximum seating capacity in the driver's cabin printed in imitation Song font on both sides of the door as required; Check whether the rear panel of trucks (including the rear panel of trailers) has the license plate number enlarged 2-3 times printed on the outside as required, and whether the sides of the doors of individual or joint-operation vehicles have the word "individual" printed on them; the characters must be clear, and unit codes or other patterns are not allowed (special cases require approval from the vehicle management office).
