• Variable Geometry Turbocharger (VGT): The VGT is a high-tech turbo with adjustable vanes in the turbine housing. These vanes change the flow of exhaust gases, improving boost response and efficiency across the rpm range. VGTs are great for maximizing performance in diesel engines. Many modern diesel engines come standard with VGTs.
• Twin-scroll Turbocharger: This Cummins ISF 2.8 Turbocharger has a unique design that splits the turbine housing into two scrolls. The exhaust pulses from adjacent cylinders are grouped in separate channels. This improves the turbine's efficiency and reduces lag. Twin-scroll turbochargers work well for small displacement engines or those with uneven firing orders.
• Twin-Turbocharger: As the name suggests, this turbocharger uses two turbines and compressors. The twin-turbo setup allows for more airflow and boost levels. It is split into two types: parallel and sequential. In parallel twin-turbos, each turbine serves all cylinders equally. In contrast, the sequential setup has one turbine for half the cylinders. The other turbine boosts the remaining cylinders.
• Capable Turbocharger: VGT and twin-scroll technologies combine into the capable turbo. This turbo is suitable for high-performance applications. It is often found in sports cars and racing vehicles. The capable turbo provides maximum boost at high engine speeds.
• Electric Turbocharger: This is a new turbo technology still being developed. The electric turbo uses an electric motor to spin the compressor. This eliminates turbo lag and provides instant boost. Electric turbos can improve efficiency and reduce emissions in engines.
• Variable Twin-scroll Turbocharger: The VNT is a versatile turbo. The VNT combines the VGT and twin-scroll technologies into one unit. This turbo is suitable for high-performance and heavy-duty applications. The VNT provides smooth power delivery and high boost across the entire engine speed range.
