What is the difference between t and l in car displacement?

[LaneRose]

The difference between t and l in car displacement is: 1. Different nature: t represents a turbocharged engine; l represents a naturally aspirated engine. 2. Different principles: t is equipped with a turbocharger; l is when air simply passes through the air filter, throttle, intake manifold, and reaches the cylinder. Car displacement is a specialized term in hydraulic transmission, referring to the volume of fluid inhaled or discharged per stroke or cycle. Car displacement is an important parameter to measure a car, and its displacement ranges include: below 1.0L, 1.0 to 1.1L, 1.3L, 1.4 to 1.5L, 1.6L, 1.7L.

I've been driving for over a decade and have experienced both turbocharged and naturally aspirated engines. The core difference lies in the air intake method. Naturally aspirated engines rely on the engine's own suction, delivering exceptionally smooth power output – step on the accelerator and the power comes instantly, driving feels as comfortable as silk gliding. Turbocharged engines, however, use exhaust gases to drive the turbine and increase air intake, delivering significantly more power, but with a slight lag of a few tenths of a second during acceleration, like it needs to catch its breath before delivering full power. In terms of fuel consumption, turbocharged engines of the same displacement are actually more fuel-efficient because they can deliver greater horsepower with smaller displacement. However, maintenance costs are higher, with stricter oil requirements, making long-term maintenance costs 20-30% higher than naturally aspirated engines. Naturally aspirated engines feel more relaxed for city driving, while turbocharged engines show greater advantages on highways and long-distance trips.

Simply put, a turbocharged engine with a "T" is like adding a blower to the engine, forcing more air into the same displacement to burn more fuel, resulting in stronger explosive power. Naturally aspirated engines rely solely on atmospheric pressure to draw in air, making the breathing process smoother. The biggest advantage of turbocharging is that it allows a small 1.5L engine to deliver the power of a 2.0L engine, while manufacturers pay less displacement tax, which is why more and more cars now use "T" engines. However, naturally aspirated engines provide more linear acceleration—the power output directly corresponds to how much you press the throttle, offering more precise control. I particularly love the silky smoothness of naturally aspirated engines, especially when driving on mountain roads where you can precisely control the speed in every corner. Turbocharged cars can sometimes surge unexpectedly, requiring extra caution when managing the throttle, particularly in stop-and-go traffic.

Young drivers care more about the sense of acceleration, and turbocharging excels in this aspect. For example, when you're first in line at a red light and step on the gas the moment it turns green, the turbo kicks in and the push-back feeling is particularly exhilarating. However, there is indeed a power lag at low RPMs, where naturally aspirated engines perform much better, delivering power on demand. Maintenance for turbocharged engines requires more attention later on, such as needing full synthetic oil, whereas semi-synthetic is sufficient for naturally aspirated engines. Nowadays, many performance cars use turbocharging, but pure sports cars like the Porsche 911 still stick with naturally aspirated engines, aiming for that ultimate smoothness. In my opinion, for daily commuting, naturally aspirated is the worry-free choice, but if you're into driving for fun, go for turbo.
