An overhauled engine is completely different from a new one, with poorer performance post-overhaul. Here are detailed reasons why an overhaul affects engine performance: 1. General Reason: Cars are mass-produced industrial products. Post-overhaul reassembly struggles to match the standardization level of production lines. Thus, engine performance typically declines after an overhaul. 2. Bolt Reason: Normally, engine bolts are in a tightened state with a specific tightening sequence. During post-overhaul assembly, bolt handling often lacks precision.

What does TGDi mean?

TGDI stands for Turbocharged Gasoline Direct Injection. Below are specific details about turbocharging: Classification: Turbocharging is divided into four types: mechanical supercharging, pressure wave supercharging, exhaust gas turbocharging, and compound supercharging. Turbocharging is essentially an air compressor that increases engine intake air volume by compressing air, thereby enhancing engine power and torque, making the car more powerful. Function: The primary function of turbocharging is to increase engine intake air volume, thereby boosting engine power and torque. When a turbocharger is installed on an engine, its maximum power can increase by 40% or more compared to when it is not equipped with a turbocharger. This means that the same engine can generate greater power after being turbocharged.
