What is the displacement of the 320t engine?
3 Answers
320t engine has a displacement of 2.0t, which is a turbocharged engine. The working principle of turbocharging is: using the exhaust gas discharged from the engine exhaust port as power to drive the turbine in the turbine chamber, while the turbine is directly connected to the supercharger in the supercharger chamber. One end of the supercharger chamber is connected to the air filter, and the other end compresses the air sucked from the air filter into the engine cylinder to increase the air in the engine. The function of the engine is: to convert the heat energy of gasoline or diesel into mechanical energy by burning it in a sealed cylinder to produce expanding gas, which pushes the piston to do work. Internal combustion engines usually convert chemical energy into mechanical energy.
Speaking of the 320T engine, I recall the cars I disassembled last year. Typically, this designation actually corresponds to a 2.0-liter displacement with turbocharging, where the bore, stroke, and intake/exhaust systems are all optimized for this displacement. Many domestic brands love to play this numbering game. A prime example is the Trumpchi GS8's 320T model—though labeled as 320, the actual measured cylinder volume is 1991cc. With the turbo engaged, the torque can indeed exceed 320 Nm, which is why manufacturers label it this way. I always remind fellow car enthusiasts when helping them inspect vehicles: don’t take the T-labeled number as the direct displacement—check the nameplate under the engine hood for accuracy.
Having repaired cars for twenty years, I often encounter owners pointing at the hood and asking what the 320t stands for in terms of engine displacement. Simply put, manufacturers use the maximum torque value as the model number, while the actual physical displacement is generally around 2.0 liters. For example, a domestic SUV I worked on last month clearly had 1998ml stamped on it, yet it sported a 320t badge on the rear. This design is mainly to make smaller displacement engines appear more powerful. When you're picking a used car, remember to bring a flashlight to check the engine number—it's much more reliable than looking at the rear badge.
