Methods for controlling the ignition advance angle: The ignition advance angle can be adjusted using a vacuum gauge. During adjustment, it is necessary to refer to the data of the highest vacuum value of the car engine in the idle state. The fuel supply point can be aligned with the high-pressure pipe's fuel outlet according to the scale. The ignition advance angle is a parameter that affects the performance of the car engine during operation, representing the moment of ignition. Advanced ignition in a car refers to the spark plug firing before the piston reaches the compression top dead center, igniting the combustible mixture in the combustion chamber. The angle through which the crankshaft rotates from the moment of ignition to when the piston reaches the compression top dead center is called the ignition advance angle. An ignition advance angle that allows the car engine to achieve better power and fuel economy is considered a good ignition advance angle, making it a very important parameter for the car.

How to use the air conditioning in the Tiguan L?

Press the AC button on the front control panel to turn on the air conditioning, then adjust the fan speed button, and the air vents at the front of the car will blow cold air. Usage method: AC is the air conditioning switch, MAX means maximum, and the internal circulation can be manually turned on or off. By default, when the air conditioning is turned on to the maximum state (or when the temperature difference between the inside and outside of the car is relatively large), the internal circulation will automatically turn on; in other cases, it generally does not turn on automatically. Taking the Volkswagen Tiguan L 2018 Modified 330TSI Automatic Two-Wheel Drive Luxury Edition as an example: 1. After starting the Volkswagen Tiguan L 2018 Modified 330TSI Automatic Two-Wheel Drive Luxury Edition, wait for 5-10 minutes until the water temperature rises to normal temperature, then you can turn on the warm air. 2.

Can you turn right when the straight-through light is red without a right-turn light?

You can turn right when the straight-through light is red without a right-turn light, but you need to be careful not to affect the passage of straight-through vehicles and pedestrians on the crosswalk, otherwise you will be deducted 3 points and fined 200 yuan. Whether it is a straight-through arrow red light or a full-screen red light right turn, the vehicle must be in the rightmost motor vehicle lane, otherwise, driving not according to the lane will result in points deduction and fines, and it is also easy to cause rear-end accidents. When driving at an intersection with traffic lights, pay attention to: When driving at an intersection with traffic lights, you should pay attention to slowing down in advance and not getting too close to the car in front. If the car in front is relatively tall, such as a bus or a large passenger car, you should keep a greater distance. When driving, you should not only look ahead but also observe the situation on the left and right sides of the car more often. You can use the left and right rearview mirrors to check. If it is an arrow signal light, because it will indicate the direction of travel, you should drive correctly according to the display of the arrow indicator light, and you must not drive when the light is red. There are three types of driving a motor vehicle not according to the prescribed lane: Driving a motor vehicle on the highway not according to the prescribed lane, violation code: 43120, fine standard: deduct 3 points, fine 100 yuan; Driving a motor vehicle on the urban expressway not according to the prescribed lane, violation code: 13550, penalty standard: deduct 3 points, fine 100 yuan; Driving a motor vehicle on roads other than highways and urban expressways not according to the prescribed lane, violation code: 60230, penalty standard: no points deduction, fine 100 yuan. Preventive measures: In view of the severe situation of traffic safety, in order to achieve the annual work goals of reducing the number of accidents, the number of deaths, the mortality rate per 10,000 vehicles, and the number of major traffic accidents compared with the same period last year, the national traffic management departments of public security organs will continue to thoroughly implement the spirit of the April 17 meeting, deepen the "five rectifications and three strengthenings" work measures, comprehensively promote the "safe and smooth county" activity, and continue to carry out special rectification.

What does Subject Two include?

The C1 license Subject Two test for small cars includes five mandatory items: reverse parking, parallel parking, hill start and stop, right-angle turn, and curve driving (commonly known as S-curve). In some regions, there is a sixth item: highway toll card collection. The C2 license Subject Two test includes four mandatory items: reverse parking, parallel parking, right-angle turn, and curve driving (commonly known as S-curve). Reverse Parking: Reverse parking is one of the most practiced and considered challenging items in the Subject Two test. The most critical point during the test is that the car must not stop midway; otherwise, the test will be considered a failure. Before preparing to park, the candidate can observe the garage boundary lines through the rearview mirror to determine the steering wheel angle for reversing. The car body should maintain a distance of 1.5 to 1.8 meters from the boundary line, and the car should start reversing slowly once the front of the car crosses the infrared line. When the right rear window's vertical trim aligns with the upper right corner of the yellow boundary line, the steering wheel should be turned fully to complete the reverse parking. Parallel Parking: Parallel parking is a commonly used skill in daily driving. The candidate must drive the car parallel to the parking space and then reverse into it without any pauses. As long as the car is parked within the designated area without crossing the boundary lines, the test is passed. Note that stopping midway will result in failure. Hill Start and Stop: During the hill start and stop test, candidates are most concerned about stalling. When the car is stopped on the slope, the handbrake must be engaged to prevent rolling back. The process of starting, accelerating, and passing the slope constitutes the hill start test. Rolling back will also result in point deductions. Right-Angle Turn: During the right-angle turn, the candidate must control the car's speed and complete a 90-degree sharp turn at low speed without stopping. Failing to complete the turn or stalling midway will result in point deductions. It is important to position the car close to one side of the road to make the turn easier. Curve Driving: Curve driving requires the candidate to have a good sense of the car. The car must navigate an S-shaped path of a specified width without touching the boundary lines, and the steering must be smooth. The purpose is to develop the driver's ability to control the car's direction and track the wheel trajectory. Mastering this skill will make the test easier.

What is the charging current for a car battery?

Car batteries typically have a charging current of 12V. Here's a relevant introduction to car batteries: Function: Also known as storage batteries, they provide the electrical energy needed for starting a car and help balance the output and load of the generator. Most car batteries are 12V60A, consisting of 6 individual cells with each cell having a voltage of approximately 2V. Maintenance: Modern maintenance-free batteries mostly use alloy plate grids, which enhance corrosion resistance and tensile strength. The electrolyte lost during charging can quickly flow back without needing any additional liquid. Maintenance-free batteries generally have strong overcharge resistance, long power storage duration, and can provide stable high-current output.
