What is the equivalent displacement of a 4.0T engine?
1 Answers
A 4.0T engine is equivalent to a 5.0L naturally aspirated engine. The 4.0T engine is a turbocharged engine, where 'T' stands for turbo, meaning turbocharged. The displacement of a car is denoted by 'L', which represents volume and exhaust capacity. 4.0T refers to adding a turbocharger to a 4.0L naturally aspirated engine. The biggest advantage of turbocharging is that it can significantly increase the engine's power and torque without increasing the engine displacement, with a typical increase rate of around 30%. A turbocharged engine is one that relies on a turbocharger to increase the intake air volume. A turbocharger is essentially an air compressor. When the engine speed increases, the exhaust gas velocity and turbo speed also increase, enhancing the air compression level and consequently increasing the engine's intake air volume, which boosts the engine's output power. When an engine is equipped with a turbocharger, its maximum output power can increase by about 40% or even more compared to when it is not equipped with one.
