Why Doesn't the Car Speed Increase Despite High RPM?

What Causes Engine Shaking After Car Shutdown?

Engine shaking after car shutdown indicates a malfunction in the vehicle. Here are some possible reasons for engine shaking: 1. Engine misfire: This mainly refers to one or more cylinders in the engine not working properly. Common symptoms include intermittent exhaust flow, severe shaking of the exhaust pipe, noticeable engine vibration, and sometimes accompanied by a sputtering sound. This is often related to ignition coil failure. 2. Worn or loose engine mounts: Engine mounts are rubber blocks placed between the engine and the frame to reduce vibration and cushion the engine's operation, as well as to secure the engine. Once these mounts become worn or loose, the engine's shaking will become significantly worse. Replacing the engine mounts can greatly reduce this issue. 3. Carbon buildup: Carbon deposits can accumulate in the cylinders, throttle body, spark plugs, and intake system. Excessive carbon buildup inside the engine can affect the ignition energy, air intake efficiency, and air-fuel mixture ratio, leading to unstable power output and shaking during idling and acceleration. It is recommended to have the engine cleaned at a 4S shop to address this problem.

What does free ETC installation mean?

Free ETC installation means that there is no charge for installing the ETC onboard unit at the bank, only requiring the completion of an application form. Currently, there is a promotion encouraging vehicle owners to apply for ETC, and making an appointment in advance can save time. ETC working principle: Through dedicated short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, using computer networking technology for background settlement processing with the bank, the purpose is achieved where vehicles can pass through highway or bridge toll stations without stopping while still paying the highway or bridge fees. The ETC installation process is as follows: Upon receiving the device, first check whether the ETC card and electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU, the red light will briefly illuminate, and the OLED screen will display "tag invalid" or "please insert card," indicating the device is functioning normally. Clean the front windshield, ensuring the glass surface is smooth, clean, and dry. Then peel off the OBU adhesive backing film and stick it to the installation position, pressing firmly with your hand for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front facing the driver and the back facing the front glass, ensuring the chip is inserted into the OBU device.

Can Alcohol Wipes Be Stored in a Car?

Alcohol wipes can be stored inside a car. Here are some precautions to keep in mind when storing alcohol wipes in a vehicle: 1. Ensure ventilation: Maintain proper air circulation inside the car, as high concentrations of alcohol vapor in enclosed spaces can easily lead to fire hazards. 2. Avoid direct sunlight: During summer, prolonged exposure to sunlight can raise interior temperatures to 60-70°C. When exposed to extended heat or when cabin temperatures reach certain levels, alcohol-containing products like wipes may expand and potentially explode, causing fires. 3. Limit quantity: Avoid purchasing large quantities of alcohol wipes as they contain flammable and volatile liquids. Storing excessive amounts in a car creates safety risks. Opt for small individually packaged wipes when purchasing, suitable for disinfecting specific areas.

Below is relevant information about highways: 1. Classification: Highways are arterial roads exclusively designed for directional and lane-separated vehicle traffic with full access control. Four-lane highways are generally designed to accommodate an annual average daily traffic volume of 25,000 to 55,000 passenger car equivalents over their projected service life. 2. Traffic characteristics: Highway design speeds vary primarily based on terrain, typically categorized into four levels in rural areas: 80, 100, 120, and 140 km/h. Urban sections usually adopt two speed levels: 60 and 80 km/h. Most highway alignments primarily consist of circular curves with transition curves, emphasizing three-dimensional spatial alignment design incorporating horizontal, vertical, and cross-sectional elements.
