How Often Should a Three-Way Catalytic Converter Be Cleaned?

What is the principle of dual-clutch transmission?

The principle of a dual-clutch transmission is that one clutch corresponds to the odd-numbered gears, while the other clutch corresponds to the even-numbered gears. When the vehicle is engaged in one gear, the other clutch and the corresponding next gear are already in a ready state. As soon as the current gear is disengaged, the next gear can be engaged immediately. Therefore, the shifting speed of a dual-clutch transmission is faster than that of a conventional automatic transmission or even a manual transmission. Advantages of dual-clutch transmission: 1. Direct shifting, minimal power loss, and low fuel consumption. 2. Through the alternating work of two sets of clutchers, seamless shifting effect is achieved.

What is the fuel consumption of the CRV?

The Honda CRV has a fuel consumption ranging between 6.4 to 7.3L/100KM, with slight variations depending on the configuration. For two-wheel drive configurations, the fuel consumption is between 6.4 to 6.8L/100KM, while four-wheel drive configurations consume between 6.7 to 7.3L/100KM. Methods to reduce fuel consumption while driving: 1. The initial acceleration at low speed is a peak fuel consumption period, so gently pressing the throttle during startup and avoiding excessively high RPM can effectively reduce fuel consumption. 2. Try to avoid unnecessary high RPM, as fluctuating engine speeds can significantly increase fuel usage. 3. Regular maintenance, including oil changes and carbon deposit removal. 4. Avoid emergency braking whenever possible. Anticipating road conditions not only enhances driving safety but also saves fuel, such as gradually slowing down before traffic lights and utilizing inertia to coast.

What to Do When the Car Key Is Lost Inside the Car?

If you can't find the key and need to use the car key, there are two solutions: 1. You can go to a 4S shop to get a replacement. The staff at the 4S shop will find the corresponding key code based on the car model, then deactivate the lost key code, and finally assign a new key code. Even if the lost key is found by someone else, there's no need to worry. 2. Go to an auto parts market to get a key replacement. However, getting a key at an auto parts market poses some security risks. The auto parts market merely copies the key code, which carries the risk of loss. 3. When buying a car, you may notice a plastic tag on the key with numbers written on it. This is actually a safeguard in case the key is lost—you can use the code on the small aluminum tag to ask the manufacturer to rematch the car key. Therefore, that small aluminum tag is very important and must be kept safe.

How often should the fuel filter in a car be replaced?

Generally, the fuel filter in a car should be replaced every 10,000 kilometers. Below are the detailed explanations: 1. Main function of the car fuel filter: The primary function of the fuel filter is to remove impurities from the gasoline. 2. Symptoms of a dirty or clogged fuel filter: When accelerating, the car's response may be sluggish, and starting the car may become difficult, requiring 2 to 5 attempts to ignite. Additionally, most car engines are equipped with disposable, non-cleanable paper filters, which typically need replacement every 10,000 kilometers. If the gasoline has fewer impurities, the fuel filter can be replaced every 15,000 to 20,000 kilometers. 3. Role of the fuel filter: The fuel filter's role is to filter out water and impurities from the gasoline.

What lights to use when driving on the highway at night?

Detailed introduction to the use of lights when driving on the highway at night is as follows: 1. During normal driving, turn on the night lights and width indicator lights. If there are no vehicles ahead, you can appropriately turn on the high beams to briefly observe the road surface and surrounding conditions at a farther distance ahead, then quickly switch to the low beams. 2. When meeting another vehicle, use a combination of high and low beams. If there is a vehicle ahead or an oncoming vehicle, switch from high beams to low beams. 3. When overtaking, switch from high beams to low beams in advance, turn on the turn signal to let the vehicle ahead understand your position and intention to overtake. The car lights include: 1. Headlights: The front lighting lights of the car are divided into low beams and high beams. 2. Fog lights: When visibility is poor in foggy weather, turn on the fog lights to distinguish them from other lights of the same color. They are located at both the front and rear of the car. 3. Brake lights: When braking, the brake lights will illuminate, installed at the rear of the car.

Do I need to turn on the turn signal for Subject 2?

There are 6 situations in Subject 2 where you need to use the turn signal: When starting the vehicle, turn on the left turn signal; When starting on the slope, turn on the left turn signal; During parallel parking, turn on the right turn signal when the vehicle passes the side parking spot and stops 30 cm away from the edge, preparing to reverse; Before shifting into reverse gear during parallel parking, turn on the left turn signal because the steering wheel will be turned fully to the right during reversing, causing the front of the car to shift left; Before exiting the parking spot during parallel parking, shift into drive gear and turn on the left turn signal, then turn it off promptly after exiting; When entering the right-angle turn area, turn on the left turn signal and turn it off promptly after completing the turn. Penalties for incorrect use of turn signals are as follows: Failure to use or incorrect use of turn signals before starting, turning, changing lanes, overtaking, or parking will result in a 10-point deduction. Turning the steering wheel within 3 seconds of turning on the turn signal before starting, turning, changing lanes, overtaking, or parking will result in a 10-point deduction. Subject 2 is scored out of 100 points, with failing, 20-point, 10-point, and 5-point deduction criteria. The test is passed under the following conditions: ① For large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, and large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required. The C1 and C2 car test items include reversing into a garage, parallel parking, slope parking and starting (canceled for C2), right-angle turns, and curve driving (commonly known as S-curves) as the five mandatory items (some regions have a sixth item: highway card collection). The A1, A2, A3, B1, and B2 large vehicle test items include stake test, slope parking and starting, parallel parking, single-plank bridge, curve driving, right-angle turns, passing through a width-limited gate, passing through continuous obstacles, bumpy road driving, narrow road U-turns, as well as simulated highways, continuous sharp mountain turns, tunnels, rain (fog) conditions, slippery roads, and emergency handling.
