What are the Causes and Countermeasures for Changes in Automotive Technical Conditions?
4 Answers
Automotive Technical Conditions: Automotive technical conditions refer to the comprehensive sum of a vehicle's appearance and performance parameter values at a specific moment, representing its operational capability. The quality of a vehicle's technical condition is generally evaluated based on performance indicators, the completeness of its equipment, and the external condition of the vehicle. Performance indicators include: power performance, fuel economy, braking performance, handling stability, and ride comfort. The technical condition of a vehicle determines its operational efficiency, safety, and environmental impact.
I've been running an auto repair shop for twenty years, and car troubles boil down to three main categories: First, mechanical wear and tear, like the constant friction between engine cylinder liners and piston rings; second, fluid degradation, where engine oil turns into 'soy sauce' and transmission fluid clumps up; third, rubber and plastic aging leading to oil or air leaks. The countermeasures are threefold: Don't starve your car—change the three filters and oil on schedule; drive gently, avoid flooring the gas pedal and sudden braking; get regular full-body check-ups, tighten loose chassis bolts when needed. Remember, cars are like people—regular check-ups are cheaper than emergency treatments. With the recent heat, I recommend focusing on checking wiring aging and AC pressure. Last week, I just fixed a car that caught fire due to melted wiring insulation.
Just discussed this topic on Douyin live. Actually, it's quite normal for a car to feel sluggish over time, but sudden breakdowns are suspicious. The main causes generally fall into three categories: rubber components start hardening after five years, leading to air leaks from seals or cracked chassis bushings; electronic sensors getting fogged up by moisture, with oxygen sensor errors being the most annoying; and oxidized electrical connectors causing poor contact. The solutions are super simple: take the car on a highway run monthly to clear carbon buildup, use an air gun to blow out engine compartment dust, and change the antifreeze every two years to prevent corrosion. Yesterday, a follower mentioned a sudden spike in fuel consumption—I suggested checking tire pressure and air filter first, as these often overlooked factors significantly impact performance.
Experienced auto repair professionals share: Metal fatigue can cause deformation of suspension control arms, sludge buildup leads to VVT timing delays, and battery sulfation results in start-stop system failures—these are all classic symptoms of technical degradation. The solution lies in addressing the core issues: transmission fluid must be changed every 50,000 kilometers, brake fluid's water content should be tested annually, and sunroof drainage holes need cleaning every quarter. With the recent rainy season, it's recommended to prioritize inspection of wiper linkage mechanisms. Last month, a vehicle owner experienced motor burnout during rain due to rusted and seized linkage.
