Effects of prolonged car idling on the vehicle: 1. If the engine remains idling for a long time, the throttle opening will be very small, leading to more severe carbon buildup in the engine over time; 2. During idling, the car's fuel consumption is quite high; 3. When the engine is idling, it is prone to knocking sounds, which can shorten the engine's lifespan; 4. Prolonged idling results in a high concentration of the air-fuel mixture in the engine and low oxygen levels in the exhaust, making it easier to damage the three-way catalytic converter. Idling refers to the engine running without any load, only overcoming the internal friction resistance of its components, without delivering power externally. The minimum stable operating speed of the engine is called the idle speed, which is one of the five basic operating conditions of an engine. A well-functioning engine typically has an idle speed ranging from 550 to 800 revolutions per minute.

How to Use the Focus Wiper?

Here is how to use the Focus wiper: 1. The wiper control lever of the Focus is located on the right side behind the steering wheel. Pushing the lever down one notch activates the single wipe mode. 2. Pushing the lever up one notch activates the intermittent wipe mode. 3. Pushing the lever up two notches activates the low-speed continuous wipe mode. 4. Pushing the lever up three notches activates the high-speed continuous wipe mode. 5. Pulling the lever back one notch activates the front washer spray. 6. Pushing the lever forward one notch activates the rear washer spray. Additional information: The power source of the wiper comes from an electric motor, which is the core of the entire wiper system. It uses a DC permanent magnet motor, and the wiper motor installed on the front windshield is integrated with the worm gear mechanical part. The function of the worm gear mechanism is to reduce speed and increase torque. Its output shaft drives a four-bar linkage mechanism, which converts continuous rotational motion into left-right oscillating motion. The vehicle's combination switch handle has a wiper control knob with three positions: low speed, high speed, and intermittent. The top of the handle is the washer button switch. Pressing the switch sprays washer fluid to clean the windshield in conjunction with the wiper.

Should You Overtake from the Left or Right Side?

Overtaking should be done from the left side. Traffic safety laws and regulations stipulate that overtaking is only permitted from the left, and penalties are prescribed for overtaking from the right. Traffic police can impose fines on drivers. For safety reasons, it is advisable to overtake from the left side of the vehicle in front whenever possible. Basic Steps for Overtaking: The technique for overtaking can be summarized as follows: accelerate and merge into the adjacent lane, accelerate straight to pass the vehicle being overtaken, and then merge back into the original lane once a safe distance is achieved. The purpose of overtaking is to achieve faster passage. When to Overtake: Overtaking is appropriate when the vehicle in front is significantly slowing down the flow of traffic due to its own reasons, and there is a safe adjacent lane available. Generally, vehicles that are commonly overtaken exhibit the following characteristics: novice drivers hesitant to accelerate, slow-moving buses or trucks, drivers unfamiliar with the route, or those talking on the phone while driving. Overtaking should be completed safely and swiftly, requiring smooth acceleration and lane merging, all while ensuring safety conditions are met.

What is the name of Subject 4?

Subject 4 is called the Safe and Civilized Driving Knowledge Test. Its main content includes aspects such as safe driving and civilized driving, particularly focusing on knowledge about response methods and corresponding measures in unexpected situations. Subject 4 extracts the requirements related to safe and civilized driving from the original Subject 1, along with safe driving skills under complex conditions and emergency handling knowledge in critical situations, and places them after the Subject 3 actual road driving test to further assess the candidate's level of traffic awareness. The main content of Subject 4 includes: safe and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods in situations like tire blowouts, and knowledge on handling traffic accidents.

How often should the antifreeze in a sedan be replaced?

Sedan antifreeze should typically be replaced every two years, or when the vehicle reaches approximately 40,000 kilometers. The functions of automotive antifreeze include: 1. Providing anti-corrosion protection for components of the cooling system; 2. Preventing scale buildup to avoid reducing the radiator's cooling efficiency; 3. Ensuring the engine operates within the normal temperature range. Precautions for using antifreeze include: 1. Regularly checking the antifreeze level and topping it up promptly if it falls below the minimum mark; 2. Observing whether the antifreeze has any turbid sediments and replacing it immediately if such sediments are present; 3. Not mixing antifreeze of different colors, as they vary by vehicle model; 4. Measuring the antifreeze's freezing point before winter to prevent it from freezing.

Can a Heavy Car Steering Wheel Be Adjusted?

Car steering wheel heaviness cannot be adjusted. Some vehicle cross shafts are prone to jamming, and applying lubricant may alleviate the heavy feeling. The reasons for a heavy car steering wheel include: 1. Insufficient tire pressure; 2. Contaminated power steering fluid; 3. Internal failure of the power assist system; 4. Poor bearing lubrication. Solutions for a heavy car steering wheel are: 1. Replenish hydraulic power steering fluid; 2. Replace circuit fuses; 3. Replace flat bearings and replenish kingpin grease; 4. Increase lubrication for steering tie rod ball joints. Steering wheels are categorized into: single-spoke, dual-spoke, three-spoke, and four-spoke designs. Their working principle involves transmitting torque to the rack-and-pinion mechanism to facilitate wheel rotation left or right.

What are the three main components of an AC contactor?

An AC contactor mainly consists of an electromagnetic system, a contact system, and an arc extinguishing system. It is generally used to start equipment, control the forward and reverse rotation, start and stop of motors through different control wiring methods, and achieve remote control by adjusting the length of control cables. Changing the wiring method can also enable multi-point control. The AC contactor is a common low-voltage control device in power drive and automatic control systems. When the electromagnetic coil is energized, the moving iron core is attracted by electromagnetic force, causing the moving contacts to directly or through lever transmission come into contact with the stationary contacts, thus closing the circuit. When the electromagnetic coil is de-energized, the moving iron core automatically returns under the action of the reset spring.
