Is it safe to store alcohol in a car?

Storing alcohol in a car is not recommended as it poses safety risks to both drivers and passengers. Alcohol is highly flammable and volatile. If stored in glass bottles with convex lens-like shapes that focus sunlight, it may ignite the alcohol and cause severe explosions. Precautions for using alcohol as a car disinfectant include: 1. Alcohol being a flammable substance, immediately wipe dry after spraying; 2. Store alcohol in well-ventilated areas with windows open; 3. Focus on spraying surfaces rather than hard-to-reach interior spots; 4. Avoid smoking in the car after disinfection to prevent explosions or fires; 5. Refrain from using alcohol to clean leather seats.

How to Check Tire Wear Level?

To check tire wear level, observe the thickness from the top to the bottom of the tread grooves. Tires need replacement when: 1. Exceeding service life or mileage limit; 2. Severe tread wear; 3. Abnormal tire pressure; 4. Significant tire cuts. Precautions for tire replacement: 1. Check production date - inventory shouldn't exceed 3 years; 2. Inspect tread pattern and color for abnormalities; 3. Ensure smooth transition between tread and sidewall; 4. Avoid mixing tires with different structures/sizes. Tire functions: 1. Support vehicle weight; 2. Absorb road shocks and vibrations.

How to Cancel the Auto Start-Stop Function in Corolla?

The method to cancel the auto start-stop function in Corolla is: simply press the auto start-stop button. The auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop during driving and restarts it when it's time to move forward again. The Corolla is a compact car under Toyota, featuring a 4-door, 5-seater sedan body structure. Its dimensions are: length 4635 mm, width 1780 mm, height 1455 mm, with a wheelbase of 2700 mm. The Corolla is equipped with a 1.2L inline 4-cylinder turbocharged engine, delivering a maximum power of 85 kW, with the maximum power achieved at 5200 to 5600 rpm.

What is the ignition advance angle?

The ignition advance angle is between 6 to 12 degrees. It refers to the crankshaft's rotation angle from the moment the spark plug fires (before the engine piston reaches the compression top dead center) until the piston reaches the compression top dead center. The ignition advance angle system consists of a microcomputer, various sensors, and an ignition actuator. The adjustment method for the ignition advance angle is: 1. Check if the platinum contacts show signs of burning; 2. Remove the secondary chamber vacuum hose from the vacuum advance compensation device, block the two ports connected to the hose, and let the engine idle; 3. Use a timing light to check the ignition advance angle; 4. Rotating the distributor housing counterclockwise will increase the ignition advance angle; 5. Rotating the distributor housing clockwise will decrease the ignition advance angle.

What does the car ECU mean?

ECU in a car is the engine control unit. The ECU control unit makes adjustments to the vehicle's operating system by comprehensively analyzing driving data such as vehicle speed, engine RPM, and transmission gear position. Introduction to ECU: The ECU is referred to as the brain of the engine. During engine operation, the ECU collects data, processes it, and then controls the engine's operation through control mechanisms. Engine sensors transmit data to the ECU, which, after processing, adjusts the engine's operating state via actuators. The ECU is generally installed in the engine compartment. Functions of the ECU: The main function of the electronic control unit is to compute, process, and judge the information input from the air flow meter and various sensors based on its stored programs and data. It then outputs commands, providing the fuel injector with electrical pulse signals of a certain width to control the fuel injection volume. The electronic control unit consists of a microcomputer, input/output circuits, and control circuits. ECU Features: ECUs generally have self-diagnostic and protection functions. When a system fault occurs, it can automatically record the fault code in RAM and implement protective measures by reading substitute programs from the inherent programs to keep the engine running. At the same time, these fault messages are displayed on the dashboard and remain illuminated, allowing the owner to promptly identify the issue and drive the car to a repair shop.

What are the new driving test regulations?

The new driving test regulations are as follows: 1. Adjustment of test subjects: For small automatic transmission vehicles, the 'hill start' item in Subject 2 has been canceled, reducing the test content from the original 5 items to 4 items. This change aims to align with actual driving requirements and reduce the burden on candidates. 2. Adjustment of test scheduling time: For obtaining a small automatic transmission vehicle driver's license, the interval for scheduling the Subject 3 test has been shortened from 30 days after passing Subject 1 to 20 days. For obtaining a large or medium-sized passenger or truck driver's license, the interval for scheduling the Subject 3 test has been shortened from 40 days after passing Subject 1 to 30 days. 3. Adjustment of the number of cross-regional subject tests: For applying for a small vehicle driver's license, the number of times allowed to apply for changing the test location has been adjusted from 1 time to no more than 3 times, to meet the needs of the public for cross-regional testing.
