Is 30 cm mandatory for hill start?

Yes, otherwise points will be deducted. The information about hill start is as follows: 1. Project introduction: Hill start is a project in the second subject of the driver's license test, which is to start the vehicle parked on a steep slope upwards. 2. Hill start skills: First pull the handbrake, step on the accelerator to at least 2000 rpm, then release the clutch until about 1000 rpm, then release the handbrake, release the clutch a little and step on the accelerator a little, and the car will naturally go uphill. After the test starts, shift to first gear, release the handbrake, gently release the clutch, and after the vehicle stabilizes, go up the slope, try to stay within 30 cm of the sideline, try to control the clutch, keep the vehicle speed as slow as possible, and use the reference object to align with the pole for fixed-point parking to ensure that the front of the car is aligned with the pole, so that the fixed-point is in place.

What are the causes of high idle speed in sedans?

The causes of high idle speed in sedans are: 1. The idle switch does not close; 2. Malfunction of the idle control valve; 3. Air leakage in the intake pipe; 4. Incorrect valve timing; 5. Fuel injector dripping or clogging; 6. Blockage in the exhaust system; 7. The EGR valve opens during idle conditions. Solutions for high idle speed in sedans: 1. Adjust or replace the throttle position sensor; 2. Clean or replace the idle control valve, and use a decoder to perform basic idle speed setting; 3. Locate the leakage point, reseal or replace related components; 4. Check the timing marks and readjust the valve timing according to standards; 5. Clean and inspect the fuel injection volume of each injector and confirm for any blockages or leaks; 6. Replace the three-way catalytic converter; 7. Remove carbon deposits on the EGR valve or replace the EGR valve.

What are the main components of engine oil?

Engine oil is composed of base oil and additives. For mineral oil, the base oil is refined from petroleum; for fully synthetic oil, the base oil is artificially synthesized. The following are the functions of automotive engine oil: 1. Lubrication and friction reduction: It forms an oil film on the surfaces of two sliding components to prevent friction during operation and ensure smooth movement. 2. Cleaning and dispersion: High-quality engine oil can flush away dirt from component surfaces through oil flow, adsorb tiny metal fragments in the engine, and then scrape them into the oil pan via the piston oil ring. 3. Cooling: The engine generates high temperatures during operation. When the oil reaches the operating parts, it absorbs heat and carries it away, aiding in component cooling. 4. Sealing and leakage prevention: It forms a seal between the piston rings and pistons through an oil film, preventing combustion exhaust gases from entering the crankcase. 5. Rust and corrosion prevention: High-quality engine oil adheres to component surfaces, protecting them from contact with air, acidic substances, and harmful gases, thus safeguarding the engine from corrosion by atmosphere and water.

How to Properly Control Vehicle Speed in Subject 2 Driving Test?

Here are the techniques for properly controlling vehicle speed in Subject 2 driving test: 1. When operating the clutch, depress quickly but release slowly. The correct pedaling posture is: place the ball of your foot on the pedal to prevent foot slippage. 2. Gently lift and lightly press the clutch, maintaining a movement range within 3cm. After the vehicle starts moving, if you feel it accelerating without clutch adjustment, gradually press the clutch slightly. When speed decreases, gently lift it a bit, keeping adjustments minimal. 3. On uneven road surfaces, lightly apply the brake to control speed. Brake pressure should increase gradually - avoid sudden braking. 4. Whether starting on flat ground or slopes, accurately identify the clutch's semi-engaged state. Develop the habit of slowly lifting the clutch to semi-engagement first, then releasing the brake until the vehicle gradually moves. 5. When stopping, first depress the clutch, then the brake. After shifting to neutral, you may release the clutch before the brake.

What Type of Barrel is Safe for Storing Gasoline?

Storing gasoline in an iron barrel is relatively safer. Reasons for using an iron barrel: Even if static electricity is generated, the metal barrel conducts electricity, allowing charges to transfer easily without accumulating, thus preventing sparks. If a plastic barrel is chosen for storing gasoline, precautions must be taken to prevent static electricity. It is essential to use non-polar plastic, which does not generate positive or negative charges. Containers made of high-molecular insulating materials must never be used to store gasoline, as they can generate positive and negative charges, leading to sparks and explosions. Precautions for gasoline storage: It is best to use metal containers for storing gasoline, ensuring the container is tightly sealed to prevent gasoline from evaporating or leaking. The container should not be filled to the brim; leave some space to allow for the expansion of volatile gasoline components, avoiding excessive internal pressure. The storage barrel should not be placed near open flames or high-temperature areas and should ideally be kept in a cool, well-ventilated warehouse. It is not advisable to store gasoline for extended periods, nor is it recommended to store excessive amounts of gasoline.

How Many Stabilizer Bars Does a Car Have?

Family sedans are typically equipped with only two stabilizer bars: the front lower control arm stabilizer link and the toe adjustment stabilizer link. Below are detailed specifications about stabilizer bars: 1. The characteristic of a stabilizer bar is that it does not function when both left and right wheels pass over the same road bump or pothole. However, if the left and right wheels encounter different road bumps or potholes, meaning the horizontal heights of the two wheels differ, it causes torsion in the bar, generating anti-roll resistance (Roll-Resistance) to suppress body roll. 2. Types of stabilizer bars include the front lower control arm stabilizer link (standard factory component), toe adjustment stabilizer link (standard factory component), front shock tower strut bar (commonly known as "top strut bar" in Hong Kong and Macau; optional), front crossmember stabilizer link (commonly known as "front lower strut bar"; optional), rear shock tower strut bar (commonly known as "rear top strut bar"; optional), rear suspension reinforcement stabilizer link (commonly known as "rear lower strut bar"; optional), and chassis/body reinforcement stabilizer links (assembly).
