Is Turbocharging Represented by T or L?
2 Answers
Turbocharging is represented by T. Below is an introduction to turbochargers: 1. Advantages: The greatest advantage of a turbocharger is that it can significantly increase the engine's power and torque without enlarging the engine displacement. After installing a turbocharger, the engine's power and torque can increase by 20% to 30%. 2. Disadvantages: The drawback of a turbocharger is lag, meaning that due to the inertia of the impeller, there is a delayed response to sudden changes in throttle input, causing the engine to delay in increasing or decreasing power output. For cars that need sudden acceleration or overtaking, there might be a momentary feeling of insufficient power.
Last time when I got my car repaired, the mechanic explained it clearly - turbocharged engines are mostly labeled with 'T', like Volkswagen's 1.4T or Ford's 1.5T. But be careful, some cars have badges like 280TSI or 330TFSI on the rear, which actually indicate turbocharging. Naturally aspirated engines are marked with 'L', such as the old Toyota 2.0L. Once when I helped a friend inspect a used car, I immediately knew it was turbocharged when I saw '1.8T' on the engine cover, while '2.0L' would mean naturally aspirated. Hybrid models are more complicated - for example, Lexus' 2.5L hybrid still uses a naturally aspirated engine principle despite having electric components.
