What is the EPS system in cars?

Car EPS system is an electronically controlled power steering system that can reduce steering force at low speeds to improve the maneuverability of the steering system; at high speeds, it can appropriately increase steering force to enhance handling stability. This system directly provides steering assistance through an electric power motor, eliminating the need for components such as power steering oil pumps, hoses, hydraulic fluid, drive belts, and pulleys mounted on the engine, which not only saves energy but also protects the environment. The main structure of the EPS system consists of a steering sensor device, vehicle speed sensor, power-assisted mechanical device, steering assist motor, and microcomputer control unit.

How often should the diesel filter be replaced?

The diesel filter should be replaced every 5,000 to 7,500 kilometers. The method for replacing the diesel filter is as follows: 1. Close the fuel inlet ball valve and open the upper cover; 2. Unscrew the drain plug to drain all the dirty oil; 3. Loosen the tightening nut at the top of the filter element, and the operator should wear oil-resistant gloves to firmly hold the filter element and remove the old filter element vertically upwards; 4. Install the new filter element, place the upper sealing ring properly, and tighten the nut; 5. Tighten the drain plug, cover the upper cover, and fasten the bolts. The diesel filter, abbreviated as diesel filter, is one of the three filters. Its main function is to filter the diesel in the diesel engine to improve its cleanliness and lubricity, providing clean diesel to the internal combustion engine, thereby generating heat energy and converting it into thermal energy.

What to Do If Vehicle Emission Test Fails?

The solutions for failing vehicle emission tests are: 1. Replace spark plugs and clean fuel injectors: Insufficient spark energy from spark plugs may lead to incomplete combustion of the air-fuel mixture, resulting in excessive HC levels in the exhaust. Additionally, poor atomization from fuel injectors or an overly rich mixture can cause the vehicle to fail the emission test. 2. Use higher-grade gasoline: Higher-grade gasoline is cleaner and significantly reduces harmful gases like CO, NO, and HC after combustion. Using higher-grade gasoline during the annual inspection can help pass the test. 3. Drill a hole in the tailpipe: Creating a hole in the tailpipe allows outside air to enter the testing equipment, diluting the concentration of harmful gases in the exhaust and making it easier to pass. 4. Upgrade the vehicle's software system: Many modern vehicle modules support software upgrades. Visit a 4S shop to upgrade the vehicle's ECU, improving fuel injection, ignition, and exhaust treatment performance to pass the annual inspection smoothly.

How to Turn On Daytime Running Lights?

Daytime running lights do not require manual activation. Under normal circumstances, they automatically turn on when the engine starts and do not need to be manually switched on by the driver. When the headlights are turned on, the daytime running lights will either automatically turn off or dim. Daytime running lights, also known as daytime running lamps (DRLs), are designed to signal the presence of the vehicle to others during the day and are typically installed on both sides of the front end. These lights are not meant for illuminating the road for the driver but rather to alert others that a vehicle is approaching, falling under the category of signal lights. They must meet basic brightness requirements without being overly bright to avoid disturbing others. Unlike standard low-beam headlights, DRLs are specifically designed for daytime visibility. Those utilizing LED technology offer enhanced energy efficiency and gradually increase in brightness to better capture the attention of other motorists, cyclists, and pedestrians. As night falls and the driver manually activates the low-beam headlights, the daytime running lights will automatically turn off.

Can a Dash Cam Record Conversations Inside the Car?

Can a dash cam record conversations inside the car? Yes, as long as the audio recording function is enabled. After installing a dash cam, it can record the entire driving process, including video images and sound, which can serve as evidence in traffic accidents. There is usually a dedicated recording button on the dash cam. A dash cam is an instrument that records images, sound, and other relevant information during vehicle travel. For those who enjoy road trips, it can also be used to document challenging journeys. It continuously records while driving, capturing time, speed, and location in the footage. Additionally, it can function as a parking monitor. It's important not to edit the recorded video footage, as doing so may render it useless in the event of an accident. This also helps prevent fraudulent claims, which are unfortunately common in today's society.
