What are the Five Major Taboos in Using Diesel Turbocharged Cars?
1 Answers
Diesel turbocharged cars have five major usage taboos as follows: 1. Sudden acceleration: A key feature of turbocharged cars is quick acceleration, but you should not floor the accelerator immediately after starting, as this can easily damage the turbocharger oil seal. 2. Do not shut off the engine immediately: After prolonged high-speed operation, suddenly turning off the engine while it is still hot can cause the residual oil in the turbocharger to overheat, damaging the bearings and shaft. Therefore, let the engine idle for a minute or two before shutting it off. 3. Oil quality: Turbochargers often operate at speeds exceeding 150,000 RPM, and improper oil usage can significantly affect the turbo's lifespan. Always use the manufacturer-recommended or higher-quality full synthetic oil to provide excellent lubrication for the turbocharger and engine, reducing friction and wear. 4. Avoid prolonged idling: During idling, the engine and turbocharger operate at low speeds, causing the gas pressure inside the turbo and compressor to drop below the pressure in the bearing housing. This can lead to oil leakage into the compressor and turbo, depriving the bearings of proper lubrication and cooling. Additionally, oil leaking into the compressor may enter the cylinders, affecting engine performance. Therefore, avoid excessively long idling periods. 5. Frequent high-temperature operation: Due to exposure to high temperatures, the oil inside the lubrication lines can partially coke, leading to insufficient lubrication of the turbocharger bearings and potential damage.
