There is not a person on the planet that hasn’t seen the twin turbocharged Cummins on a video, but do we really know how this setup works and why it is much better than the single turbocharger? Some of the people think that double is better, and it is so true. But how are the two turbochargers connected and how are they working together on the same engine? This is where the engineering part of the video kicks in and the host from Engineering Explained is going to explain it all for us, made simple too.

So we all know how the turbocharger works. Being connected to the exhaust of the engine the turbine gets its power from there. Sometimes reaching 120 000 RPM. When the turbine of the turbocharger spins at the same time it is sending the compressed air to the engine. The more the RPMs the more pressure in the engine, thus more power coming from the pistons with the stronger detonations. Now is it the same with the twin turbo setup on the engine? It is totally the same and the process is the same too. The only difference is that the twin turbo setup can only be used on the V style engines. Each turbocharger is going to work on its own side of the engine with no interference between them. Placing the two turbochargers on the inline engine would be redundant, with the one turbo charger just left out of the picture.

On the V engine the turbochargers are in parallel position, we got that right. But what would happen if the two turbo chargers are placed in sequential order on the inline engine? Would this still work pushing double the PSI into the engine? Sure it will, one turbo will work while the engine is in low RPM and then the two pushing when the HIGH RPM are reached.
