Different Flat & Boxer Engine Configurations Explained | Flat-Twin to Flat-16

The Difference between the Flat and Boxer engines:

A “flat” engine is one with a 180-degree cylinder angle (which often lays flat in the vehicle) and is also correctly referred to as a “horizontally-opposed” engine.


A Boxer engine will feature an individual journal for each connecting rod, 180 degrees apart from one another. This allows each pair of opposing pistons to mirror each other’s movements.

which is more durable for 4 wheel drive 4 to 6 in line or 4 to 6 boxer engines

Subaru, damn you. I love those boxer style hamster wheels.

inline six and V12 are the best engines for cars or even trucks(Tatra V12 air cooled). for motorcycles V4 engines or inline six for perfectionists!

Man i wish there was a modern 5+ litre boxer 8 engine

Well
When i crashed my 2004 subaru impreza
The engine ended up beneath the car rather on my lap,so it's a win for me

Why does engine (crank) not rotate opposite direction when it starts?

you forgot to ad alfa romeo flat 4

beautiful video, thanks

Tucker automobiles are awesome.

Porsche rules!!!!

The Porsche 718 GTS does not have a flat-6. It hast a flat-4. so sad

Thanks 👍 Happy Christmas 🎄

aparently you forgot about Tatra 11 (1923–1927)

Best engines ever. BMW boxers: best bikes ever 😎👍

The Rotax you show has water-cooled heads. It's not purely an "air cooled engine".

The Rotax engine you showed for the aircraft flat 4 is both air and water cooled so you’re carrying heavy water. You would have been better off showing a Lycoming or Continental 4 cylinder. They’re purely air cooled.

THIS VIDEO IS FREAKING AMAZING! IVE HAD A RELATIONSHIP WITH THE FLAT-4 SINCE I WAS A PRE-TEEN. NATURALLY MY FIRST CAR WAS A 69 VW BEETLE. THE REST IS HISTORY. I WASNT AWARE OF THE ABUNDANCE OF INFORMATION RELATING TO THE FLAT DESIGN. THEY'VE ALWAYS SEEMED TO UNCOMMON AND OBSCURE. DATED OR RARE. DIDNT KNOW HOW OFTEN MANUFACTURERS WENT BACK TO THE DESIGN

Big thumbs up for the mention of Richard Pierce's motor.

Volkswagen lost a lawsuit in the 50's to Tatra over the air cooled engine designs

Interesting. But You've forgot to mention Lancia Flavia 1.5, 1,.8, and 2.0 liters flat Boxer fours. They were lightweight alloy engines developed in the '60s.

V 180 ° pistons

He didn't mention the Testarossa, which had a flat 12

The most common flat engines are every Number of cylinder engines? Except a single cylinder which can’t possibly be a boxer engine nor even flat.

Basically, the only real advantages of a V configuration with OHC and 6 or more cylinders over flat engines are width, oiling and, critically, aftermarket support. IMO as a retired Industrial Design Engineer and fabricator.

No mention of the Alfa Romeo boxer 4?

thank god for BRZ

ボクサーエンジンを語るなら、水平対向とⅤ型１８０度の違がいを理解して無いと駄目と思う。

Two minutes in and I am impressed, he knows 2, 4, 6, 8, 10 lmao

Do the rotary engine please

you are the best one.

Soviet T-64 tank uses 5 cilinder opposite 5TD engine.

Sir" really great explanation
Master speaking . Thanks.

Er the Porsche 918 has 4 not 6 cylinders

Correction...Ferrari 12 cyl. BOXER engine for F1 was (312) was introduced in 1970 in the 312B, not in 1975 in the 312T.

Interesting video. Quite a few mixed up photos, but otherwise pretty well done.

No H-16?

Flat 4 in a 2006 Beetle? Rear drive? I wish.

Not really buying the 'too expensive to produce' argument (with regard to cylinder heads). Most V configurations require 2 heads as well. GM produced millions of examples of the Small Block V8.

O Alpha Romeo, Alpha Romeo, wherefore art thou Alpha Romeo?

So if I’m understanding this correctly, a flat engine (excluding 180 v engines) has pistons that don’t move simultaneously in pairs while a boxer does? Or is there more differences?

why not repl the cyl heads with crankshafts and make an opposed piston engine?

thank you sir for information ❤

for the two cylinder boxer engine like the BMW motorcycle engine, crankcase free breath causes a lot of pumping loss.
