What is the 1243 valve adjustment mnemonic for a 4-cylinder engine?

The valve clearance adjustment for a 4-cylinder engine can be summarized with the mnemonic 'Double, Exhaust, No, Intake.' However, different types of engines and the positions of their intake and exhaust valves may vary, leading to differences in the valve clearance adjustment sequence. Below is a detailed explanation: Valve Adjustment Sequence and Method: Taking a 4-cylinder engine with a known firing order of 1-3-4-2 as an example. First, position cylinder 1 at the compression top dead center (TDC) and adjust its valves. Then, rotate the engine crankshaft 180 degrees to position cylinder 3 at the intake bottom dead center (BDC) and adjust the clearance. Next, rotate the crankshaft another 180 degrees to position cylinder 4 at the exhaust top dead center (TDC) and adjust the clearance. Finally, position cylinder 2 at the power top dead center (TDC) and adjust the clearance. Adjustment Considerations: In addition to following the correct sequence, the size of the valve clearance is also crucial. If the valve clearance is adjusted too small, the valves may not close properly, leading to reduced engine power. If the clearance is too large, it will increase the impact frequency of the valve train components, accelerating wear. It can also cause delayed valve opening, resulting in improper engine operation and reduced power.

How soon can I get a D license?

Generally, it takes about a month to obtain a motorcycle driver's license. Unlike ABC-class driver's licenses, all subjects of the motorcycle license test can be completed on the same day. Here is an introduction to the relevant content: Basic motorcycle test items include stake test, hill start, parallel parking, single-plank bridge crossing, curve driving, right-angle turning, speed-limited passing through narrow gates, continuous obstacle passing, 100-meter gear shifting, and bumpy road driving. Motorcycle: A two or three-wheeled vehicle driven by a gasoline engine and steered by handlebars to control the front wheel. It is lightweight, flexible, fast, and widely used for patrol, passenger, and cargo transportation.

Can I Bring a Turned-off Phone into the Car During the Subject 2 Driving Test?

Mobile phones are not allowed during the driving test. Generally, before entering the examination area, the safety officer will remind candidates to store their phones in a secure locker. Below is relevant information: Introduction: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment and refers to the field driving skills test. Test Attempts: Candidates are allowed one attempt for the Subject 2 test. If they fail, they can retake it once. If they choose not to retake or fail the retest, the current test session ends, and the applicant must reschedule the test after ten days. Within the validity period of the driving skills test permit, the number of scheduled attempts for Subject 2 and Subject 3 road driving skills tests must not exceed five. If the fifth scheduled test is still unsuccessful, the results of other previously passed subjects will be invalidated.

Will Gasoline Cars Be Phased Out?

Gasoline cars will not be phased out at present. The following are precautions for engine maintenance: Fuel must be clean: If the fuel contains a high amount of impurities, it will accelerate the wear of the electric fuel pump and reduce its service life. Dirty fuel can also cause blockages in the fuel filter and fuel injectors, affecting fuel supply pressure and normal fuel injection, thereby reducing the engine's performance. Correct fuel selection: Engines have high requirements for fuel quality and grade, especially for electronically fuel-injected engines. For cars equipped with catalytic converters and oxygen sensors, only unleaded high-grade gasoline should be used. If leaded gasoline is used, the exhaust catalytic converter will fail after driving more than 400 kilometers, the oxygen sensor will also malfunction, and the normal operation of the engine will be affected.

What Oil is Used for Wet Dual-Clutch Transmissions?

Wet dual-clutch transmissions use hydraulic oil. Below are some precautions regarding vehicle refueling: Avoid overfilling: Overfilling the fuel tank can easily block the vent hole. Once the vent hole is blocked, the pressure inside the tank will drop below normal levels, leading to poor fuel supply or even a complete lack of fuel. Overfilling also increases the vehicle's weight, thereby increasing fuel consumption. Additionally, gasoline can deteriorate, posing safety risks. Try to avoid waiting for the low-fuel warning before refueling: While driving, always monitor the fuel gauge. When the indicator shows only a quarter of the fuel remaining, it's time to refuel. If the tank remains empty for too long, the temperature difference between the inside and outside can cause moisture to form inside the tank, leading to corrosion, degraded fuel quality, and increased engine strain.

What are the test items for Subject 2?

The test items for small car C1/C2 licenses include five mandatory items: reverse parking into a garage, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as S-turns). Some regions may include a sixth item: highway toll card collection. According to Article 25 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses" (Ministry of Public Security Order No. 123), effective June 1, 2021, the stopping and starting on a slope item was removed for C2 and C5 license tests. For large vehicle A/B licenses, Subject 2 includes 16 items: reverse parking into a garage, passing continuous obstacles, curve driving, highway simulation test, limited-width gate, bumpy road, single-plank bridge, narrow road U-turn, stopping and starting on a slope, parallel parking, highway emergency handling, mountain road simulation, right-angle turns, rain and fog weather simulation, highway tire blowout, and tunnel simulation driving. For small cars, a score of 90 is required to pass. The Subject 2 driving test is scored out of 100, with criteria for failing, deducting 20 points, 10 points, or 5 points. To pass, applicants for large buses, tractors, city buses, medium buses, and large trucks must score at least 90, while other license types require at least 80. Article 44 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses" states that each test can be taken once, with one retake allowed if failed. If the retake is not taken or is failed, the test process ends, and the applicant must reschedule. Within the validity period of the learner's permit, the number of attempts for Subject 2 and Subject 3 practical tests must not exceed five. Failing the fifth attempt invalidates any previously passed subjects. According to Article 19 of the "Road Traffic Safety Law": driving a motor vehicle requires a legally obtained driving license. Applicants must meet the conditions set by the public security department and pass the test to receive the appropriate license. Drivers must operate vehicles within the license's permitted categories and carry the license while driving. It is illegal to drive without a license or to drive a vehicle type not covered by the license. As clarified by the Legislative Affairs Office of the State Council, driving a vehicle type not covered by the license is considered unlicensed driving. Penalties may be lighter but still fall under Article 99 of the "Road Traffic Safety Law": driving without a valid license, or during suspension or revocation, may result in fines and up to 15 days of detention.
