What Are the Reasons for Lower Car Idle Speed Than Before?

Car idle speed refers to the operating state of the car when the engine is idling. The following are the reasons for lower car idle speed than before and their solutions: 1. The idle speed may have become lower due to a dirty throttle body. 2. Cleaning the throttle body is necessary, and the air filter should also be cleaned. Low idle speed can cause the following hazards: 1. With low idle speed, the car is prone to stalling when decelerating or stopping (commonly seen when waiting at traffic lights or slowing down for turns). 2. Low idle speed affects gear shifting. 3. For manual transmissions, excessively low idle speed makes it difficult to synchronize engine gears during shifting, compromising smoothness and potentially causing gear clashes and component wear. 4. During acceleration, it may result in insufficient power, preventing the car from performing optimally.

Which Light is the Position Lamp?

Position lamps are the outermost lights at the front and rear of the vehicle. Large trucks also have clearance lamps on the roof and sides. Position lamps serve as warning lights to alert other vehicles. Installed along the top edges of the car, they indicate both the vehicle's height and width. Position lamps, also known as width markers, are easily identifiable by their symbol featuring two lamp-like icons with three lines extending left and right, representing the illumination of both side position lamps. Fog lights are characterized by a wavy line passing through the light beam. The distinguishing method for high/low beams and front/rear fog lights is that low beams and front fog lights have downward-slanting lines, while high beams and rear fog lights have horizontal lines.

What are the measures to prevent vehicle exhaust?

Measures to prevent vehicle exhaust include: 1. Improving existing vehicle power systems and fuel quality; 2. Implementing exhaust after-treatment technologies; 3. Regulating vehicle emissions through legislation; 4. Reducing vehicle usage; 5. Promoting energy-saving and emission-reduction in vehicles. As one of the primary sources of air pollution, vehicle exhaust contains numerous harmful substances, including carbon monoxide, nitrogen oxides, hydrocarbons, and particulate matter. The hazards of vehicle exhaust are: 1. It exacerbates the greenhouse effect; 2. Causes harm to human health; 3. Leads to acid rain; 4. Affects the growth of crops and forests.

What is the normal temperature for car air conditioning vents?

The normal temperature for car air conditioning vents is between 2 to 10 degrees Celsius. The method to turn on the car air conditioning is: 1. Press the AC button; 2. Turn the temperature control knob, turning to the red side for warm air and the blue side for cold air. Precautions for using car air conditioning include: 1. Do not immediately turn on the internal circulation after entering the car in summer; first open the windows to allow air convection inside the car; 2. When parking, turn off the air conditioning before turning off the engine to avoid increasing the startup load; 3. Avoid using the internal circulation for extended periods; 4. Do not arbitrarily adjust the direction of the air conditioning vents; 5. Do not set the air conditioning temperature too low; 6. Immediately turn on the internal circulation after entering the car in summer.

How much weight can the trunk carry?

Different cars have different trunk capacities, generally around 200kg-300kg. Calculating load capacity: The manufacturer provides specifications: front axle 875KG, rear axle 745KG. After deducting the curb weight, the front axle can carry 747KG and the rear axle 453KG. Subtracting these values shows the difference in load capacity between the two axles. Recommended load: The car brand and number of passengers affect trunk weight capacity. Luggage weight = Gross vehicle weight - Curb weight - Driver and passenger weight. For most 1.5L sedans, with 4 passengers you can carry about 100kg of luggage. Under normal circumstances (with only the driver), the trunk shouldn't exceed 200kg. Carrying excessive weight long-term will significantly increase fuel consumption, reduce vehicle stability, and accelerate tire wear. Generally, try not to overload the trunk.

What is the reason for the continuous flashing of hazard lights when the car is turned off?

The reason for the continuous flashing of hazard lights when the car is turned off is a problem with the control box. It is necessary to check whether the hazard light relay is functioning properly. Use a multimeter to directly measure the output line of the hazard light relay to see if there is a 12v output. If there is intermittent output variation, it indicates normal operation. If there is no output or a constant 12v output, it means the hazard light relay is damaged and needs to be replaced with a new one. The method to activate the hazard lights is to press the red triangle button on the vehicle's dashboard. The functions of hazard lights are: 1. To alert other vehicles in case of emergencies such as breakdowns or accidents; 2. To prevent rear-end collisions when parking on the roadside by turning on the hazard lights.
