Deep Dive: Inline 4 vs. V4 vs. Boxer 4 - What’s the Difference? Engine Balance Explained in Detail

In today’s video we’re doing a very in-depth exploration and comparison of the inline 4, the v4 and the boxer 4 engine. We’re exploring and comparing everything from primary and secondary engine balance to firing intervals and rocking couples. We will also see how a boxer 4 is different from a flat non-boxer engine in terms of anatomy and balance. But our deep dive is structured and gradual instead of overwhelming so that you can enjoy the video regardless of your background or prior knowledge. There’s also skip points included so that viewers familiar with my engine balance series don’t have to watch things that have already been explained in previous videos. As you might already know, primary engine balance has to do with the mass and thus the inertia of the piston when it changes direction. Now to have an engine with good primary balance we have to balance out the forces associated with the piston’s inertia. The inline four achieves a perfect primary balance by balan
