What is the function of the idle valve?

The function of the idle valve is to allow the idle controller to act based on the ignition signal. When the engine speed is below 750 RPM, the idle control valve activates to increase the engine speed. Once the engine speed exceeds 1050 RPM, it stops operating. In vehicles equipped with an air conditioning system, this control valve is also referred to as the idle speed-up valve. After the air conditioning compressor engages, it creates an engine load, causing the engine idle speed to drop. The idle control valve then activates to maintain idle stability. The idle control valve is powered by the ignition switch—whenever the ignition switch is turned to the ON position, the idle control valve receives power, and the engine control unit (ECU) manages its circuit grounding. When the engine's operating parameters deviate from normal values, this valve is used to adjust the idle speed.

Can LED Lights Be Installed Without Lenses?

It is not suitable to install LED lights without lenses, as this can cause severe light scattering, which actually reduces the visibility of the LED lights. Therefore, if you want to install LED lights, it is necessary to install lenses as well. LED bulbs have excellent light concentration, and the effect of switching between high and low beams can be achieved through the light-blocking plates inside the lenses. Without lenses, the light concentration of LED bulbs cannot be fully utilized due to the absence of light-blocking plates, leading to light scattering instead. Hence, LED lights and lenses should be installed together. If you must install LED headlights without lenses, you typically need to use high-performance LED bulbs and modify the reflector bowls for high and low beams to avoid light scattering and ensure visibility.

How to Wax a Car?

Methods for waxing a car: Before waxing, protect non-working areas such as rubber and plastic parts, which do not need wax application. Use masking tape to cover these areas to prevent wax from being applied, as dried wax can be difficult to remove. When applying wax, use a manual sponge or a waxing machine sponge in a circular motion to ensure even application and proper adhesion to the paint surface. Follow the top-down principle when waxing: start with the roof, then proceed to the front and rear hoods, and finally the sides of the car. As a traditional aspect of car detailing, waxing serves several purposes: 1. Water and acid rain protection: Wax reduces water droplet adhesion by 50% to 90%. 2. Protection against high temperatures and UV rays: Cars exposed to sunlight for extended periods can suffer from paint aging and fading. 3. Dust prevention: The friction between a moving car and the air generates static electricity; wax effectively reduces friction between the car body and air or dust.

What does mild hybrid mean in cars?

Mild hybrid, also known as MHEV (Mild Hybrid Electric Vehicle), refers to vehicles with a low degree of hybridization. Without the assistance of an internal combustion engine, the electric motor designed in the vehicle cannot drive the car alone. Mild hybrid systems typically use 36V or 42V battery packs and are equipped with a low-power starter-generator that assists the internal combustion engine via the crankshaft belt. Mild hybrids cannot be considered true hybrid vehicles because the car relies solely on the internal combustion engine for propulsion, with the battery output only providing auxiliary functions. These functions generally include automatic start-stop, smooth engine start assistance, and brake energy regeneration. The advantage of mild hybrid system design is lower cost, but the fuel savings are also relatively modest, typically ranging from 8% to 15%.

Does Prolonged Idling Damage the Car?

Prolonged idling does not cause significant harm to the car, but it directly leads to increased fuel consumption and a buildup of carbon deposits. The accumulation of carbon deposits increases with the duration of vehicle operation, so it is advisable for car owners to perform necessary cleaning every six months to maintain the engine's operational efficiency. Idling to warm up the engine, also known as soft warm-up, involves allowing the engine to idle naturally without pressing the accelerator after ignition and before driving. The engine speed during idling is referred to as the idle speed, which can be adjusted by modifying the throttle opening size.
