The differences between SOHC and DOHC engines are: 1. Different structures: SOHC uses a single overhead camshaft on the cylinder head with one camshaft that directly drives the intake and exhaust valves; DOHC has two overhead camshafts placed on the cylinder head, sealed by the valve cover. 2. Different power burst points: SOHC bursts around 2500 to 3500 rpm; DOHC bursts between 4000 to 4500 rpm. The car engine is the device that provides power for the car, consisting of the crankshaft connecting rod mechanism, valve train, fuel supply system, cooling system, lubrication system, ignition system, and starting system.

What is the sequence of B2 Subject 2?

Pole shifting, parallel parking, ramp stop, single-plank bridge, curve driving, right-angle turn, pressing cakes, passing through a width-limited gate, driving on undulating roads, narrow road U-turn, simulating continuous sharp bends on mountain roads, simulating rainy/foggy weather, simulating slippery roads, simulating tunnel driving, simulating highway driving, simulating emergency handling, etc. These are the 16 items of the B2 driver's license Subject 2 test. Below is the detailed sequence of the B2 Subject 2 test items: Pole Test: Reverse from the starting point into the B garage and stop properly, then move the vehicle two times forward and two times backward to shift to the A garage and stop properly. Then drive forward out of the B garage to the control line, reverse into the A garage and stop properly, and then drive forward back to the starting point. The vehicle must not stop during the process, and the total time must not exceed 8 minutes. Parallel Parking: After the vehicle is parked properly on the right side in front of the garage, reverse into the garage in one go without stopping. The wheels must not touch or press the lane boundary lines or the garage boundary lines. Single-Plank Bridge: During the test, the vehicle must not stop, and the wheels must not fall off the bridge. Narrow Road U-Turn: Drive the vehicle to the U-turn section and park on the right side. Complete the U-turn within no more than three forward and two backward movements. The test time must not exceed 5 minutes. Right-Angle Turn: Drive the vehicle along the specified route, making a right-angle turn from left to right or right to left in one go without stopping. The wheels must not touch or press the lane boundary lines. Slope Stop and Start: Control the vehicle to stop accurately and start smoothly without rolling backward. The start time must not exceed 30 seconds. Simulated Highway Driving: After driving to the entrance ramp, turn on the left turn signal, look back to the left to observe oncoming traffic, and after confirming safety, accelerate into the driving lane to reach the minimum speed limit and drive normally, then turn off the turn signal. When changing lanes, turn on the turn signal for the lane you intend to enter, observe the traffic situation, and change lanes after confirming safety. When exiting the highway, adjust the speed and lane in advance according to the exit warning signs. Simulated Emergency Handling: During normal driving, one of the following emergency situations will be randomly selected and simulated using voice or lights: If an obstacle suddenly appears ahead, brake immediately, stop quickly, and turn on the hazard warning lights after stopping. In case of a flat tire or other vehicle malfunction while driving on the highway, reduce speed appropriately, observe the following traffic, park the vehicle steadily in the emergency lane, turn on the hazard warning lights, prompt passengers to move outside the guardrail, place the warning sign correctly, and the driver should move outside the guardrail to simulate calling for help. Curve Driving (commonly known as S-curve): The test requires the vehicle to drive on an S-shaped road of specified width without pressing the road edge lines, with smooth steering control. This assesses the driver's ability to maneuver the vehicle through curves and control its trajectory, aiming to develop skills in steering and wheel path control. Simulated Tunnel Driving: Before entering the tunnel, observe the road traffic signs at the tunnel entrance and operate accordingly. When approaching the tunnel, reduce speed, turn on the headlights, and sound the horn. When exiting the tunnel, sound the horn again and turn off the headlights. Do not sound the horn in no-horn zones. Simulated Rainy/Foggy Weather Driving: Drive at reduced speed. In rainy conditions, adjust the wiper speed according to the rainfall. In foggy conditions, turn on the fog lights, position lights, headlights, and hazard warning lights. Simulated Slippery Road Driving: Before entering the slippery road, reduce speed. After entering, use a low gear to drive steadily and control the vehicle direction smoothly. Simulated Continuous Sharp Bends on Mountain Roads: Reduce speed before reaching the bend, drive on the right side, sound the horn before entering the bend, and avoid occupying the opposite lane while driving. Passing Through a Width-Limited Gate: Drive through the three gates at a speed of no less than 10 km/h without touching the hanging rods.

Can You Drive Away a Used Car on the Same Day of Purchase?

Generally, no. Here are some considerations when buying a used car: Check if the car meets emission standards: Currently, the China VI emission standard is in effect. If the used car is China V, be cautious as some areas may not allow China V vehicles on the road. Ensure all documents are complete: Some cars may lack registration certificates, purchase tax receipts, etc. Such used cars should never be bought, as they cannot be legally driven even after purchase. Verify if any traffic violations are settled: Some used cars on the market may have numerous pending traffic violation records. If you take over such a car, you as the buyer will be responsible for these violations.
