How to Understand Traffic Lights at Roundabouts?

Roundabout traffic lights still follow the basic rule of stopping at red and going at green. The variation is that when the intersection light is red, vehicles are allowed to make a right turn and exit the intersection while ensuring pedestrian safety. When the roundabout light is red, the innermost lane permits vehicles to continue driving around the inner circle of the roundabout, but attention should be paid to whether there are any related warning signs set up at the roundabout. A roundabout, also known as a rotary or traffic circle, is a special form of traffic node, belonging to a type of at-grade road intersection, suitable for intersections with relatively low traffic volume, serving the purpose of slowing down vehicles for turns. Roundabouts are typically designed with four lanes: the left lane is for left turns, the middle two lanes are for going straight, and the right lane is for right turns to exit the roundabout.

What are the lubrication methods for engines?

There are four lubrication methods for engines: 1. Pressure lubrication: Pressure lubrication uses oil pressure to deliver oil to various friction surfaces for forced lubrication, such as the main bearings of the crankshaft, connecting rod bearings, and camshaft bearings. It requires delivering oil to the gaps of friction surfaces under a certain pressure. 2. Splash lubrication: The rotation of the crankshaft flings oil from both sides of the bearings, forming numerous oil droplets or mist in the crankcase, which splash onto various friction surfaces for lubrication, such as the cylinder walls and piston pins. 3. Combined lubrication, which integrates pressure and splash lubrication: This method is widely used in modern automotive engines. 4. Grease lubrication: Engine accessories such as generators and water pumps use grease lubrication for their bearings, requiring periodic greasing or cleaning and replacement.

Should You Release the Clutch or the Brake First in Subject Three?

In Subject Three, when starting the vehicle, release the brake first, then engage the clutch to the semi-linked state, and finally release the brake completely. Points to note when starting: 1. When starting, slowly lift the clutch with your left foot to about halfway, and when you feel the vehicle vibrating slightly, release the handbrake promptly. 2. Then gently press the accelerator slightly. When the vehicle starts to move forward, slowly release the clutch and add a bit more throttle to successfully start. 3. Beginners should pay special attention when starting on a slope. If the handbrake is released too quickly while the clutch isn't lifted sufficiently, the vehicle may roll back. The best method is to press both the clutch and brake when starting (the handbrake is optional). Lift the clutch halfway and then release the brake. At this point, the vehicle is in a semi-clutch state and won't roll back. Simultaneously, press the accelerator and slowly release the clutch to start successfully.

Is the number of steering wheel turns the same for left and right turns?

Steering wheel left and right turns are not the same: the steering wheel turns 1.2 times to the left when fully locked, and 1.5 times to the right when fully locked. The following are related materials about steering wheel turns: 1. Coarse adjustment. Drive the vehicle on a four-wheel tester, adjust the adjusting nut of the steering tie rod to make the lengths at both ends as equal as possible, and ensure that the toe-in on both sides is close to the same value (caster is generally not adjustable) 0 degrees under the premise that the wheel camber angles on both sides are basically symmetrical. 2. Fine adjustment. Use 5053 to check whether the angles when the steering reaches the limit on both sides are roughly symmetrical within 5 to 10 degrees, then find the electronic zero position, immediately fix the steering wheel, and perform a four-wheel alignment according to the standard or required value. 3. Adjust the steering wheel position. Turn off the ignition, remove the airbag module, connect 5053, set the key to the check position (there may be an alarm), set the steering wheel to the electronic zero position, then remove the steering wheel with a puller and adjust its position.

How to Distinguish Whether the Car You Bought is China 5 or China 6 Standard?

You can distinguish between China 5 and China 6 standards from the following points: 1. If you purchased a new car, you can check the "Vehicle Factory Certificate" for the "Emission Standard" section, which will specify the standard. 2. If you purchased a used car, you can differentiate between China 5 and China 6 by checking the environmental label on the upper right corner of the windshield or the insurance policy. 3. You can also distinguish them based on carbon monoxide emissions, nitrogen oxide emissions, and PM particulate matter emissions. Below are the differences between China 5 and China 6 standards: 1. Carbon monoxide emissions: China 5 gasoline vehicles: 1000mg/km, China 5 diesel vehicles: 500mg/km, China 6a: 700mg/km, China 6b: 500mg/km. 2. Nitrogen oxide emissions: China 5 gasoline vehicles: 60mg/km, China 5 diesel vehicles: 180mg/km, China 6a: 80mg/km, China 6b: 35mg/km. 3. PM particulate matter emissions: China 5 gasoline vehicles: 4.5mg/km, China 5 diesel vehicles: 4.5mg/km, China 6a: 4.5mg/km, China 6b: 3.0mg/km.

Is the ETC toll photo on the highway for speed measurement?

ETC toll photos on the highway are not for speed measurement. Instead, they are part of a new gantry-based segmented tolling model, where both ETC and manual payment vehicles are charged based on their actual travel routes. The ETC system utilizes wireless communication and data exchange between the onboard unit in the vehicle and the antenna installed in the toll lane. The ETC system primarily consists of an automatic vehicle identification system, a central management system, and other auxiliary facilities. It employs automatic vehicle identification technology to enable wireless data communication between the vehicle and the toll station, facilitating automatic vehicle recognition and toll data exchange. By leveraging computer networks for toll data processing, the ETC system achieves fully automatic toll collection without the need for vehicles to stop or for toll booths.
