In Subject 3, the time requirement for lane changing is that the candidate must activate the left turn signal for more than 3 seconds upon hearing the instruction to change lanes, with no specific distance requirement. Below are relevant details about Subject 3: 1. Concept: Subject 3, also known as the road test, is part of the motor vehicle driver's license assessment. It refers to the road driving skills and safe civilized driving knowledge test in the motor vehicle driver's examination. 2. Different test contents for different vehicle types: The road driving skills test varies for different permitted driving models, generally including: preparation before starting, starting, straight-line driving, gear shifting operations, lane changing, pulling over, passing through intersections straight, turning left at intersections, turning right at intersections, passing through pedestrian crossings, passing through school zones, passing through bus stops, meeting vehicles, overtaking, making U-turns, and night driving. 3. Completion time: The starting procedure in Subject 3 must be completed within two and a half minutes. Regardless of the gear, the student should generally accelerate and shift gears smoothly until reaching fourth gear, with a time requirement of fifteen seconds. If road conditions permit, it is best to accelerate to 55 km/h and maintain that speed for three seconds. If conditions do not allow, the student should find another opportunity to accelerate to fourth gear and reach the specified speed. After completing this, gently apply the brake, and when the speed drops to around 35 km/h, shift to third gear and continue driving.

The essence of changing lanes in Subject 3 is safety and smoothness, with no rigid time limit, but each action must be executed properly. For example, the turn signal must be activated at least 3 seconds before changing lanes—this is a strict requirement. In terms of distance, while there's no fixed meter requirement, you must assess the actual road conditions. On a four-lane bidirectional road, a distance of around 30 meters is reasonable for completing a lane change. Remember not to turn the steering wheel immediately after signaling; observe the rearview mirror for at least 3 seconds to ensure the distance from vehicles behind is safe. Also, avoid staying on the dashed line for too long—complete the entire lane change within 5 seconds. I’ve seen trainees lose points for jerky steering movements causing noticeable vehicle sway, so controlling the steering wheel’s range is crucial.

Those who have passed the third driving test know that hesitation during lane changes can be even more dangerous. You must signal well in advance—I recommend turning on the indicator at least 30 meters ahead, but the actual timing should be adjusted based on speed: at 40 km/h, it's advisable to signal at least 10 car lengths in advance. The core action of changing lanes should be completed within 5 seconds, starting from the moment you check the rearview mirror. The key is to maintain continuous movement without interruption—for example, suddenly stopping after signaling may be judged as improper operation. Remember to turn off the indicator promptly after completing the lane change, as many test-takers lose points for forgetting this step. Another detail is that steering adjustments during lane changes should be minimal, with the steering wheel angle not exceeding 15 degrees.

What is the function of a car air conditioning filter?

The main functions of a car air conditioning filter are: 1. Provide fresh air. It prevents the car windows from fogging up, ensuring clear visibility for the driver and safe driving; it supplies fresh air to the passenger compartment, preventing occupants from inhaling harmful gases and ensuring driving safety; it effectively sterilizes and deodorizes. 2. Ensure safety and hygiene. It keeps the air in the passenger compartment clean and free from bacterial growth, creating a healthy environment; it effectively separates solid impurities such as dust, core powder, and grinding particles from the air; it efficiently intercepts pollen, ensuring that passengers do not suffer allergic reactions that could affect driving safety. 3. Adsorb harmful substances. It adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air; it has strong and durable moisture adsorption capabilities. 4. Filter solid impurities. The car air conditioning filter fits tightly into the housing, ensuring that unfiltered air does not enter the cabin. It separates solid impurities such as dust, pollen, and grinding particles from the air.

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.

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.
