**Understanding Bugatti's V16 Engine Configuration**
Bugatti's latest engine configuration is a topic of great interest among car enthusiasts and engineers alike. The company has been secretive about the details of its new powertrain, but recent photos and teasers have given us a glimpse into what's in store. In this article, we'll delve deeper into the specifics of Bugatti's V16 engine configuration and explore why it's an innovative solution for the luxury car manufacturer.
**The 90° V Engine Configuration**
One of the most striking aspects of Bugatti's V16 engine is its 90° firing interval between two cylinders sharing the same pin. This means that each cylinder will fire at a 90-degree angle to the other, creating a unique combustion pattern. For those familiar with engine configurations, this is reminiscent of a 90° V engine. However, as we'll see, Bugatti's configuration goes beyond just being another 90° V engine.
**The Odd and Even Sides**
Another interesting aspect of the engine configuration is that all odd numbers are on one side of the engine, while all even numbers are on the other side. This means that the combustion process alternates between the two sides – the odd side and the even side. In essence, this engine is a combination of two separate crossplane V8 engines. To understand this better, let's label the odd side as "A" and the even side as "B". By dividing it in this way, we can effectively have two separate crossplane V8 engines.
**Reconstructing the Firing Order**
To reconstruct the firing order of each engine, we imagine two rows of cylinders that we divide into two groups: 1 through 4 and 5 through 8. Then, another 1 through 4 and 5 through 8 mirrored for the engine with label "B". For each group, we reconstruct the firing order just like on a regular V8 engine. This gives us the firing order for each V8 engine in the crossplane configuration.
**The Crossplane Crankshaft**
In a crossplane crankshaft, the outer cylinders fire first, followed by the inner cylinders. This can be visualized as follows: four outer cylinders fire, then four inner cylinders, and so on. On Bugatti's crossplane crankshaft, the firing pattern alternates between two outer and two inner cylinders. By looking at this firing order, we can see that cylinders 2 and 3, as well as 6 and 7, are grouped together. This means that the order is "inner-outer-inner-outer". This shows that both engines are crossplane V8s, with a crucial detail that balances combustion: one engine fires an outer cylinder while the other engine fires an inner cylinder and vice versa.
**The 45° Crankshaft Rotation**
For this firing order to function correctly, each time it means we have a 45° crankshaft rotation between these two engines. This is crucial for ensuring that the firing intervals alternate correctly. When viewed from the side, one crankshaft forms across, while the other must be rotated 45° to ensure proper operation.
**Prototype Engine Photos**
Recently, Bugatti CEO Mate Remac posted prototype engine photos on Facebook, giving us a glimpse into the company's latest powertrain design. The images show the crankshaft and confirm that it is indeed a 90° V8 with a crossplane configuration. Furthermore, we can see that the engine has a 45° offset in the middle, creating two V8s that alternate power strokes every 45° of crankshaft rotation.
**The Hybrid Powertrain**
Bugatti's new V16 engine will be combined with a hybrid powertrain, which includes two electric motors at the front and a 24.8 kW battery at the rear. The V16 engine will also be paired with another electric motor to replace the turbochargers, bringing the total peak power to around 1,800 horsepower.
**Why Bugatti Chose This Configuration**
According to Mate Remac, Bugatti chose this V16 hybrid strategy to combine their two strengths – electric and combustion – into one vehicle for maximum performance. The company is committed to pursuing uniqueness from the start, even if it means making a powertrain more complex. While this might seem daunting, Bugatti's customers can rest assured that the end result will be worth it.
