At What RPM Does the Turbocharger Kick In?
1 Answers
Engine starts at medium speed, and the turbocharger will activate above 1,500 RPM. Here are some precautions for using a turbocharger: 1. Avoid flooring the accelerator right after starting: Since the turbocharger relies on engine oil for cooling, the oil's fluidity is poor during a cold start. If the turbocharger operates at high speeds under these conditions, it will experience significant wear. Therefore, let the engine idle for two to three minutes first, allowing the oil to fully lubricate before revving the engine. This extends the turbo's lifespan, especially crucial in winter. 2. For manual transmission turbocharged cars, avoid lugging the engine: Lugging occurs when the gear is too high for the actual driving conditions. For example, forcing a high gear while climbing a hill or driving at low speeds, which requires high torque, can cause lugging. This can severely damage the engine and even ruin the spark plugs. 3. Avoid prolonged idling: Many drivers prefer not to turn off the engine while waiting. However, during idling, the engine and turbocharger run at low speeds, causing the gas pressure inside the turbo and compressor to drop below the bearing housing pressure. This can lead to oil leakage into the compressor and turbine, depriving the bearings of proper lubrication and cooling. Additionally, oil leaking into the compressor may enter the cylinders, disrupting the engine's normal operation. Therefore, avoid excessively long idling periods.
