Turbochargers do complete justice when it comes to jump start and boost the engines. It compels the engine to thrust and run on it’s flying efficiency. It will help you to increase your truck’s efficiency without updating the engine facilities. Besides, everyone loves that extra speed in their veins. So, the turbochargers are the best option for you within the budget and without much hassle. But, the excess pressure can reduce the engine’s longevity and cause some other problems as well. The turbo lag is one of the most common issues with the turbochargers. It happens due to the engine protection manual that prevents the turbochargers from running in full efficiency. The turbochargers ended the V8 and V10 era from the automobile market. So, the turbochargers’ makers had to plan something newer and better to provide top-notch service and improve engine quality. Here in this article, we will discuss some different configurations of the turbochargers.
Turbochargers Types
There are about six types of turbochargers available in the market nowadays. The first one that comes on the list is the single turbo.
Single Turbo
The single turbo is the first generation member of the turbocharger family. It is very cost-effective and comes in the most straightforward design. But, the cons come at a cheaper rate. The single turbochargers don’t offer the full coverage Rev range. You have to choose a small, single turbocharger to kick in the power or a larger one to cover the Rev range. The lag issue remains the same in this turbocharger.
Sequential Turbo
If getting one small and another big turbocharger seems a hassle for you, then the sequential turbo is the option. It solves the problem very quickly. You get a small turbo to kick in power and provide a top-end grunt to cover the whole Rev range. Two in one service offers a flat torque curve that provides enough efficiency. With two turbochargers in a box, it becomes heavy, expensive, and the lag problem remains in some models.
VGT Turbo
By now, you must be feeling tired about the lag that never leaves the engine, however modification you do. So, the VGT (Variable Geometry Turbo) brought you the easy solution. It has a metal ring around the turbine that aerodynamically improves vane performance. It can change the area-to-radius ratio to fit into the engine changes. The area-to-radius radius ratio creates more power in low Rev to pull up the turbo. In higher Rev, the area-to-radius rate permits more air to enter the engine to keep the boost range higher. Thus, the lag problems reduce remarkably in the VGT turbochargers. Ford uses this remarkable turbocharger in their 7.3 turbo Power-stroke engines.
Twin scroll turbo
The turbo runs with the exhaust gas from the engines. The exhaust gas enters and forces the turbine to produce the boost for the engine. Now, the gas enters in pulses to the machine, and you can easily imagine the gas entrance can overlap and have lag. After improving the mechanism, so much money wants that same old lag in their engine. The twin turbos solved the problem. Here, both turbos come into action using the divided inlet for the turbine. In this process, the right cylinders connect with the same sided turbos. That means you can change the first and third cylinders with one turbo In a four-stroke engine. It not only reduces the lag problems but also improves engine efficiency.
Conclusion
Turbochargers came as a blessing in the automobile industry. There are some problems with the aerodynamic designs and engine lags. But, with each new model, the advantage list is getting longer.
