What are the components of the engine electronic control system?

The components of the engine electronic control system include the electronic spark advance system (ESA), electronic fuel injection system (EFI), exhaust gas recirculation (EGR), idle speed control system (ISC), and intake control system, among others. Generally, control systems other than the electronic fuel injection system and electronic ignition system are collectively referred to as auxiliary control systems. The engine electronic control system, abbreviated as the electronic control system, controls engine ignition, fuel injection, air-fuel ratio, and exhaust emissions to ensure the engine operates under optimal conditions, achieving good vehicle performance, energy savings, and reduced exhaust emissions. The electronic fuel injection system includes fuel injection quantity control and injection timing control. The primary function of the exhaust gas recirculation system (EGR) is to reduce nitrogen oxide (NOx) emissions. The idle speed control (ISC) system adjusts the engine's air intake via the idle control valve based on factors like engine coolant temperature, whether the air conditioning compressor is operating, and whether the transmission is engaged, ensuring the engine always runs at the optimal idle speed. The intake control system manages the engine's air intake according to changes in engine speed and load to improve the engine's volumetric efficiency, thereby enhancing engine performance.

How to Repair Minor Scratches on Headlights?

You can use toothpaste for polishing, as toothpaste contains abrasive particles. Apply toothpaste to the headlight and then rinse it off with water. For longer scratches and cracks on car headlights, you can use fine wood sandpaper to sand them down, followed by polishing with polishing wax. The principle is similar to polishing the paint surface. Use nano-spray coating for renovation and repair, including sanding, degreasing, spray coating, and spectral hardening. The repair process strictly follows the original headlight manufacturing process.
