What is a flat four? What is a boxer engine? This video will explain the benefits of a flat engine, specifically a flat four engine with horizontally opposed pistons. The main advantages of a boxer engine are the primary and secondary engine balance, and the very low center of gravity compared to other engines. H4 engines are one of the best engine designs, however they are more costly than the inline counterpart.
The biggest advantage of the boxer engine is the low profile, which keeps the center of gravity low and thus reduces the amount of load transfer you have in the car during braking, cornering, or accelerating, which improves grip. With a lower center of gravity, you can also reduce body roll and choose to use softer springs. Additionally, in the event of a collision, it’s easier to position the engine so that it goes underneath the passenger compartment, rather than into the passenger compartment, for improved safety.

    I've said it once, I'll say it again - this guy embodies everything that's great about KZread. Unrivaled knowledge coupled with a natural talent for teaching... add to this the seldom-seen ability to include only what we really need to know, and what we have is an absolutely indispensable learning resource. The fact that, through KZread, we get all that for free necessitates the burning question: why are we paying $$$$s for inferior quality tuition from college? Huge respect to EE!

    All the gaskets are missing. Spark plugs, etc. Just smaller stuff. I think the timing belt tensioner is there, but not a 100% copy. Its a non working model. Its simplified with keeping the main parts. If you start adding these smaller components, it becomes a huge challenge to get everything to work correctly. The original commenter is talking about the failure of the piston rings in wrx engines. Its a known problem, but there are solutions to it now.

  • @elusivellama

    As far as I can tell, these are the disadvantages of a boxer (feel free to correct me on any of these). Interested to hear your thoughts. * complexity - compared to an inline, a boxer has double the camshafts, heads, valve covers, and has a two piece split crankcase PLUS larger and heavier intake and exhaust manifolds due to how far apart the ports are on either side of the engine. Also, separate crank pins for each piston. * cost - more components to design and manufacture, engine is harder to assemble. As cost goes up (especially for boosted engines), Subaru is forced to choose whether to make a good but expensive engine, or an inferior engine (compared to the previous) that costs less to make. * not good for power (at this price point) - the two piece crankcase can warp because they're held together by bolts, and the bearings can be out of clearance under high power as the engine twists or shifts. You have two extremes of heat (cylinders) separated by a middle portion of relatively cool engine, which also contributes to this problem. If this engine were designed and made to overcome these problems, cost and weight goes up. * worldwide use - only 2 manufacturers use boxers in their cars today, Subaru and Porsche. If the boxer is so superior, why don't we see them being used by all the other manufacturers? Also, the bulk of worldwide research is overwhelmingly on the inline engine, while research is only done by Subaru and Porsche on the boxer.
