What is an Evaporator?

Why does the engine throttle fluctuate up and down?

Engine throttle fluctuation can be caused by a clogged air filter; malfunctioning or faulty intake sensor; dirty fuel injectors, etc. Solutions: If the fuel tank negative pressure switch is clogged or the negative pressure suction pipe is leaking, preventing normal fuel flow, it is necessary to unclog the fuel tank negative pressure switch and repair the negative pressure suction pipe. If the carburetor is clogged or there is water at the bottom of the carburetor float chamber, the carburetor should be unclogged and the water at the bottom of the float chamber should be removed. Precautions: Always allow the engine to cool down before washing the vehicle. Suddenly rinsing the engine, exhaust pipe, and other components with cold water can cause damage due to thermal expansion and contraction, which is a well-known principle. This can damage the oil seals in various parts, leading to engine oil leakage—many motorcycle enthusiasts experience minor engine oil leakage for this reason. It can also cause the chrome plating at the connection between the exhaust pipe and the engine to peel off, oxidize, and rust.

What are the consequences of overloading the trunk?

Overloading the trunk for a short period may not cause significant issues, but the heavier the load, the more fuel the vehicle consumes. Prolonged overloading can wear out tires, brakes, and shock absorbers. Driving uphill with a fully loaded trunk for extended periods can cause the engine to overheat, while driving downhill can lead to brake overheating and loss of braking effectiveness. Below are precautions for trunk usage: 1. Avoid flammable and explosive items: Since the trunk is an enclosed space, temperatures can rise rapidly. Storing lighters, hairspray, or other flammable/explosive items in the trunk during summer heat or long-distance travel can lead to explosions with unimaginable consequences. 2. Avoid storing valuables: Placing valuables, premium cigarettes, or fine liquor in the trunk is highly unsafe. Thieves are cunning, so never leave valuables in the car trunk.

Is a Seat Cushion Needed for Subject Three?

According to personal needs, you can bring a cushion. Below is relevant information about the driving test Subject Three: 1. Introduction: Subject Three includes the road driving skills test and the safety and civilized driving knowledge test, which are part of the motor vehicle driver's license assessment. It is the abbreviation for the road driving skills and safety and civilized driving knowledge test subjects in the motor vehicle driver's test. The content of the road driving skills test varies for different types of vehicles eligible for driving. 2. Specific Test Content of Subject Three: The road driving skills test generally includes: preparation for getting on the car, light simulation test, starting, driving straight, gear shifting operation, changing lanes, parking on the side, going straight through intersections, turning left at intersections, turning right at intersections, passing pedestrian crossings, passing school zones, passing bus stops, meeting vehicles, overtaking, turning around, and driving at night. The safety and civilized driving knowledge test generally includes: requirements for safe and civilized driving operations, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations such as tire blowouts, and knowledge of handling after traffic accidents.

What is the reason why the Focus driver's window cannot be raised or lowered with one touch?

Focus driver's window cannot be raised or lowered with one touch may be caused by a malfunction of the remote window regulator. Here is an introduction to the one-touch window function in cars: 1. Introduction to one-touch window: One-touch window refers to the vehicle's computer receiving a signal from the window switch when it is lifted and released within a set time, sending a continuous command to the window motor to raise the window until it is fully closed. 2. Anti-pinch function: One-touch window must be used in conjunction with an anti-pinch function, otherwise it is easy to cause injury, as the motor's force is still quite strong. This is also why many car models have a one-touch down function but not a one-touch up function. If there is an anti-pinch function, there is an additional motor current monitoring and control circuit. If the motor current increases beyond a certain range, it is assumed that there is an obstruction preventing the window from rising, causing motor overload, and the motor will stop.

Why Shouldn't Driver's License and Vehicle Registration Be Left in the Car?

Why shouldn't driver's license and vehicle registration be left in the car? The main reason is to prevent criminals from stealing them, which could lead to a series of negative consequences. However, keeping the driver's license and vehicle registration in the car can also be convenient in certain situations, such as when traffic police inspect the vehicle or when the driver commits a traffic violation, as they can be easily provided and presented. Below is some information about electronic driver's licenses: 1. Introduction: The electronic driver's license, commonly known as the "e-license," serves as a supplement to the physical license. In cases where the physical license is not carried, the electronic version can be used for roadside inspections, etc. 2. Driver's License: The full name of the driver's license is the motor vehicle driver's license, also referred to as a "driving license." It is a legal document required for individuals to operate motor vehicles. Driving a motor vehicle requires certain driving skills. Without these skills, driving a motor vehicle recklessly could lead to traffic accidents. Generally, individuals without a license are not allowed to drive on the road.

What is the fuel consumption per 100 kilometers for family cars?

Fuel consumption per 100 kilometers = Fuel consumption (liters) ÷ Distance traveled (kilometers) × 100. The usual calculation method is to fill up the fuel tank when the fuel gauge light comes on, reset the trip odometer to zero, and then record the trip odometer reading when the fuel gauge light comes on again. Divide the amount of fuel added by the distance traveled and multiply by 100 to get the fuel consumption per 100 kilometers. Here are some methods to reduce fuel consumption: 1. Check the air conditioning system in summer: Air conditioning malfunctions are a major cause of high fuel consumption. Poor cooling performance leads to higher fan speeds and lower temperatures to achieve a cooling effect. 2. Frequent hard braking: Frequent hard braking is a primary reason for high fuel consumption in cars. While ensuring safe driving, make full use of the vehicle's inertia. 3. Avoid excessive air conditioning in small-displacement cars: For vehicles exposed to the sun, do not turn on the air conditioning immediately after entering. First, open the windows and set the fan to a higher speed without turning on the air conditioning to expel the hot air inside. Wait for the vehicle to cool down moderately before turning on the air conditioning.
