What type of car is Subaru?

Is it normal for the 12123 driving test to be postponed for half a year?

12123 driving test is normal if it is stipulated to be postponed for half a year. Here are some related introductions about the driver's license: 1. Driving requirements: According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses", the driving scope of a C1 driver's license includes small and micro passenger cars, light and micro trucks; light, small, and micro special operation vehicles; small passenger cars with a seating capacity of less than or equal to 9 people. According to this standard, a C1 license cannot drive vehicles with more than 9 seats. 2. Requirements for test vehicles: light ordinary trucks with a length of not less than 5 meters, or small ordinary passenger cars with a length of not less than 4 meters, or cars with a length of not less than 4 meters.

What are the common knowledge points of safe and civilized driving?

Both the road driving test and the safe and civilized driving knowledge test in Subject 3 have a full score of 100, with a passing score of 90. Subject 3 test items: Subject 3, which includes the road driving skills test and the safe and civilized driving knowledge test, is part of the motor vehicle driver's license assessment. It is the examination subject for road driving skills and safe and civilized driving knowledge in the motor vehicle driver's test. The content of the road driving skills test varies depending on the type of vehicle being licensed. Difficulties in the Subject 3 test: Mismatch between speed and gear. Errors related to high gear at low speed and low gear at high speed should be noted during the test. Deviation in straight-line driving. Many trainees deliberately slow down during driving due to concerns about the driving path not being straight, which is not advisable.

What is the wattage of a normal 48V motor?

A normal 48V motor is 800 watts. Below are some related introductions about car batteries: 1. Car battery: A car battery, also known as a storage battery, is a type of battery. Its working principle is to convert chemical energy into electrical energy. 2. Maintenance of car batteries: (1) Do not start the vehicle frequently. In winter, when the car is difficult to start, avoid continuous starting. Continuous starting of the motor will definitely cause excessive discharge and damage to the battery. The interval between restarts should be more than 5 seconds. (2) When the battery has been in use for about two and a half years, routine maintenance should include battery testing to prevent potential issues. Try to avoid using electrical devices such as CD players or cigarette lighters when the vehicle is not running, and minimize the use of various onboard electrical devices while driving.

What are the causes of high idle speed in motor vehicles?

There are many reasons that can cause high idle speed in vehicles, which are detailed as follows: Idle speed control valve malfunction: The normal idle speed of an electronic fuel injection engine is determined by the idle speed control valve. The electronic control unit (ECU) calculates signals from engine speed, temperature, throttle position, and air conditioning switch, then adjusts the idle speed control valve to open the intake bypass channel or directly increase the throttle opening, thereby increasing the air intake to raise the engine idle speed. If oil contamination or carbon deposits cause the idle speed control valve to stick or the throttle to fail to close properly, the ECU will be unable to accurately regulate the engine's idle speed. Intake system air leakage: Under normal circumstances, the air intake must be strictly controlled. If there is a leak in the intake pipe, the air flow sensor cannot measure the actual air intake, leading to inaccurate air intake control by the ECU and resulting in unstable vehicle idle speed. Fuel injector dripping or clogging: If the fuel injector drips or becomes clogged, it cannot spray fuel according to the ECU's instructions, causing the air-fuel mixture to become too rich or too lean. This leads to poor performance in individual cylinders and unstable idle speed.

What does engine ECU mean?

Engine ECU is the abbreviation for Electronic Control Unit, also known as the vehicle's onboard computer. As one of the core components of modern automotive electronics, there may be several ECU electronic control units in a car, each managing different functions, and these ECU systems exchange information with each other. An engine is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, Stirling engines, steam engines, jet engines, electric motors, etc. For example, an internal combustion engine typically converts chemical energy into mechanical energy. The term engine can refer to both the power generation device and the entire machine including the power unit.

What are the 8 fuel-saving methods for older cars?

The 8 fuel-saving methods for older cars include minimizing brake usage, reducing throttle input, and coasting in neutral at higher speeds. Below are precautions regarding automobile engine usage: 1. Avoid coasting in neutral: The engine inherently features fuel-cut during deceleration, making neutral gear counterproductive for fuel economy. 2. Maintain vigilant observation during vehicle operation: If oil stains are detected on the ground, promptly assess whether engine oil leakage has occurred and consult with the authorized 4S dealership to eliminate potential safety hazards. 3. Avoid immediate engine shutdown: For turbocharged vehicles, refrain from turning off the engine immediately after high-speed driving or hill climbing. Allow 10 minutes of idling before shutdown, as turbocharged engines accumulate carbon deposits several times faster than naturally aspirated engines. 4. Replace or filter brake fluid: When brake fluid becomes contaminated with water or contains visible impurities/sediment, promptly replace or thoroughly filter it to prevent insufficient braking pressure that may compromise braking performance.
