What is the concept of drunk driving?

Drunk driving refers to the act of driving when the alcohol content in the driver's blood is greater than or equal to 20mg/100ml but less than 80mg/100ml. Moreover, drunk driving and driving under the influence (DUI) face two completely different legal consequences: drunk driving is a crime, while DUI is a traffic violation under the law. The effects of alcohol on driving are introduced as follows: Decreased tactile ability after drinking: After drinking and driving, due to the anesthetic effect of alcohol, the tactile sensation of hands and feet is reduced compared to normal, making it difficult to properly control the accelerator, brake, and steering wheel. Decreased judgment and operational abilities after drinking: After drinking, the reaction time to light and sound stimuli is prolonged, and the time for instinctive reflex actions is also extended. The coordination between sensory and motor organs, such as the eyes, hands, and feet, becomes impaired, making it difficult to accurately judge distance and speed, leading to traffic accidents. Visual impairment caused by drinking: Drinking can temporarily impair vision, causing unstable images and reduced color discrimination, making it difficult to detect and correctly interpret traffic signals, signs, and markings. Additionally, drinking significantly narrows the field of vision, blurs images, and causes the eyes to focus only on targets directly ahead, making it difficult to detect hazards at the periphery of the visual field, increasing the risk of accidents. Drowsiness after drinking: This manifests as irregular driving patterns, poor spatial vision, and other behaviors characteristic of fatigued driving.

What does the EPC light on the dashboard mean?

The EPC indicator light has two activation states: illumination during power-on self-test and illumination under other circumstances. The power-on self-test is an indication that the vehicle is monitoring the status of all sensors before driving. Generally, if the vehicle is not started after power-on, the light will turn off by itself after about 3 seconds. In other cases, if the EPC light remains illuminated after the vehicle is started or does not turn off for an extended period, the main causes may include faults in the engine intake system, throttle valve, fuel system, engine, ECU control unit, or brake lights. Below is a detailed introduction to the reasons for the EPC light illuminating under other circumstances: Engine intake system fault: The EPC light will activate if the engine intake is obstructed or insufficient. Throttle valve fault: Carbon buildup is a common issue with throttle valves. Additionally, dirt accumulation can affect intake, causing the indicator light to illuminate. Fuel system fault: Issues such as substandard fuel, fuel deterioration, or poor fuel atomization can trigger the light. Engine fault: Insufficient engine pressure or problems with the intake valves or other powertrain components may also cause the EPC light to activate. ECU control unit fault: For example, interference with the vehicle computer signals or false alarms from the vehicle computer. Brake light fault: Situations like non-functional brake lights, faulty brake switches, or brake circuit issues can lead to the EPC light illuminating. Solutions for when the EPC light illuminates: Troubleshoot intake system issues, use fuel with the appropriate octane rating, clean the throttle valve, etc. Remove carbon deposits from relevant components. Re-flash ECU-related data. If the EPC light illuminates, the owner can first try turning off the engine and restarting it to see if the light remains on. If it does not illuminate again, there may be no issue, and the EPC light might have been affected temporarily. If the EPC light remains illuminated or frequently activates, the vehicle should be taken to the nearest service center for professional diagnosis and repair to eliminate potential safety hazards. The full English name of EPC is Electronic-Power-Control, which translates to electronic power control. Most people refer to it as the engine electronic stability system. The EPC system primarily includes controllers and sensors related to the powertrain. When sensor data in the system is abnormal, the EPC system will take predefined actions to address the powertrain issues. Common EPC indicator lights are usually displayed in two colors: yellow and red. If the EPC fault light is yellow and the vehicle can still operate normally, drive slowly to a repair facility for inspection. If the EPC fault light is red, the situation is more severe, and the vehicle should be pulled over immediately to contact professional repair services. Continuing to drive may directly affect the vehicle's core components or driving safety.

What is the source of electricity in a car?

Although a car does not have an external power source, it has its own power supply and can generate electricity autonomously, which constitutes the car's charging system. There are two power sources in a car: one is the battery, and the other is the alternator. Below is a detailed explanation: 1. Battery: It can store a certain amount of electrical energy. Before the engine starts, all electrical power in the car is provided by the battery, such as starting the engine, playing music, and the car's anti-theft system. 2. Alternator: It serves as the main power source in the car. When the engine is running normally, all electrical power is supplied by the alternator, with excess electricity stored in the battery. When the alternator cannot meet the car's electrical demands, the battery provides supplementary power to assist the alternator. Together, these two components form the car's power supply system.

Is the Honda Accord 3.5 engine the same as the Acura?

The Honda Accord 3.5 engine is the same as the Acura 3.5 engine, and this engine is very advanced. The Honda VCM engine technology and principles are as follows: Honda VCM Engine Technology: Simply put, it can operate as a V6 engine or, depending on the engine's operating conditions, "transform" into an inline 3-cylinder or V4 engine. The VCM system can precisely adjust the engine's displacement according to the driving conditions, ensuring it always matches the power requirements, significantly improving fuel efficiency. Honda VCM Engine Principle: When the engine starts, accelerates, or climbs hills in lower gears, all six cylinders are activated. This ensures uniform heating of the engine block during the initial startup or meets the power output demands. In this mode, the engine can quickly deliver maximum power or torque as needed.

How to Determine the Quality of an Oxygen Sensor?

Here are specific methods to judge the quality of an oxygen sensor: 1. Observe the color to determine: (1) The normal color of the oxygen sensor tip is light gray. Any change in the color of the oxygen sensor tip indicates a fault or potential fault in the oxygen sensor. (2) A black-tipped oxygen sensor is caused by carbon contamination. After removal, carbon deposits should be cleaned from it. (3) If the oxygen sensor tip is found to be reddish-brown, it indicates lead contamination, which is caused by the use of leaded gasoline in the car. 2. Measure the resistance value of the oxygen sensor to determine: When the engine temperature reaches normal, unplug the oxygen sensor's wire connector and use a resistance meter to measure the resistance value between the terminals of the pressure sensor. The resistance value should meet the standard requirements for the specific vehicle model (generally 4-40Ω). If the resistance value does not meet the requirements, the oxygen sensor should be replaced.

What is the recommended annual mileage for a new car?

Under normal circumstances, it is appropriate for a new car to run 20,000 to 30,000 kilometers per year. Here are some precautions for using a new car: 1. Cold start warm-up: Proper warm-up helps form an "oil film" between engine components, reducing wear. 2. Timely gear shifting: During the break-in period for manual transmission models, shift gears promptly and appropriately to avoid incorrect behaviors like high gear with low RPM or low gear with high RPM, and do not use a single gear for extended periods. 3. Timely maintenance: Simply follow the manufacturer's recommendations in the vehicle manual to perform inspections and maintenance, such as changing engine oil and oil filters, and conducting a comprehensive check of the chassis system after reaching certain mileage or time intervals. 4. Avoid emergency braking: Emergency braking not only impacts the braking system during the break-in period but also increases the shock load on the vehicle's chassis and engine.
