What is the equivalent of a 2.0 naturally aspirated engine compared to a turbocharged one?
1 Answers
A 2.0T engine is equivalent to a naturally aspirated engine with a displacement of 2.5-2.7 liters. The differences between naturally aspirated and turbocharged engines are as follows: 1. Different principles: Naturally aspirated engines utilize the pressure difference between the engine and the external air to draw in air; turbocharged engines use the exhaust gases generated during machine operation to drive a compressor for air intake. 2. Different fuel efficiency: Naturally aspirated vehicles are more fuel-efficient in urban driving conditions; turbocharged cars show significantly reduced fuel consumption at high speeds, i.e., after reaching higher speeds. When the engine runs at high RPM for extended periods, the temperature at the turbocharger inlet becomes very high. If the engine is stopped immediately, the oil lubrication also stops, but the turbocharger's rotor continues to operate. Without sufficient lubrication and cooling, the bearings and shaft may be damaged. It is recommended to let the engine idle for about 3 minutes before shutting it off.
