Know The Difference In Biturbo Vs. Twin Turbo Here

The car engine is a vital part of your vehicle. When you plan to purchase an automobile, the chances are that you will come across a whole spectrum of technical jargon related to the automobile industry. There are many technical terms, which are not easily understandable to an average consumer. Two of these jargon include the two types of car engines, namely biturbo and twin-turbo engines. The car engine is the heart of the vehicle, without which it is just a piece of metal. Besides, many car owners want to understand the difference between biturbo vs. twin turbo engines.

Understanding About The Biturbo And Twin Turbo Engine

Twin-turbo is one of the most popular types of car engine turbochargers today, also known as Parallel turbo – parallel twin turbochargers. This is a term that refers to an engine with two turbochargers (also known as twin turbochargers) of the same size, placed in parallel and responsible for compressing the intake air into the engine. 

However, because the Twin turbo is installed in parallel and has a simpler design than the Bi-turbo, it processes fewer emissions and has limited engine rpm. In addition, the cost of using a Twin turbo is quite expensive because the pistons and crankshaft must be stronger to meet the correct technical requirements and properties. Finally, the structure of this twin turbocharger is more complex than that of a single-engine (single-turbo), so a larger capacity oil pump system is required to maintain continuous operation.

Bi-turbo is also an engine system with two turbochargers but of different sizes, also known as Sequential turbo – sequential dual turbocharger. This turbocharger operates with low exhaust flow and delivers more power at less rpm. When the driver accelerates, the large Bi-turbo turbocharger will generate more power through the compression valve.

The Biturbo Vs. Twin Turbo Engines – A Detailed Comparison

Different car manufacturers utilize various components inside their vehicle, which makes them stand out from the rest. One of these components includes the car engine, which dictates the overall performance of the car. 

Twin-turbo is a parallel twin turbocharger first used in SOHC engines in 1981-1994. Later, they were developed into 4 Bi-turbo turbochargers in the W16 engine. So if you want to understand in detail the difference between biturbo and twin turbo car engines, then read on below. You will get complete information on what comprises a twin turbo and biturbo car engine. However, do not forget that maintaining the car engine would define how far your vehicle will go on the highway.

1. The twin Turbo engine

Those looking to understand the difference of Biturbo vs. Twin Turbo must know that the twin-turbo car engine refers to the turbocharged car engine. It includes two turbochargers responsible for compressing the intake charge. The most common layout feature of these turbochargers is in parallel. The other twin-turbo layout includes sequential and staged turbocharging engines, which are useful for automobile racing applications. We will now understand how sequential and parallel twin-turbo engines perform.

2. Sequential twin Turbo engines

The Powertrain deployed in sequential twin turbochargers relies on two turbochargers of different sizes. A small turbocharger works with the lower exhaust flow and supplies more power at lower rev rates. Once the driver accelerates, the second larger-size turbocharger generates more power with a compression valve.

The compression valve allows the giant turbine to create more power at the higher end of the spectrum.

It will help you get the complete information on how to keep your vehicle in the best shape.

3. Parallel-twin Turbo engines

The layout under the hood of your vehicle would benefit more from dual turbochargers of the same size. Every turbocharger is assigned to a single bank of the engine having exhaust gasses. The turbochargers divide these gasses equally amongst themselves. These types of engines are most commonly associated with V6 or V8 engines. A parallel twin-turbo assists the first turbocharger to cylinders 1 to 3. The second to cylinders from 4 to 6 in a six-cylinder engine. Thus, these are the two categories of twin-turbo car engines, which offer the best performance to those looking to drive in speed.

We hope that you have understood the two basic types of twin turbo car engines. Now it is time to understand what comprises a biturbo engine.

4. The Biturbo car engine

The biturbo car engine is a fancy term for the twin-turbocharged car engine. Those looking to know what are biturbo engine should understand that the word “bi” refers to the turbochargers inside the car engine. These help to provide more air into the engine, which allows them to generate more horsepower at a smaller size. The engine is fuel-efficient even without the turbochargers. It can produce better power and still be efficient in the long run. Hence, if you are looking for a car engine providing efficiency and power at the same time, choose a biturbo car engine. The Biturbo engine offers better power and efficiency to those looking to have an engine, which speaks volumes about performance.
