How do Boxer engines work? They have a low center of gravity, they win rallys and they power Porsches! This episode of Science Garage compares the squat boxer engine to it’s tall inline 4 cousin. It uses a reciprocating motion to balance pistons and create power! From Subaru STI’s to Porsches, these low lying dynamos have a special place in the hearts of car fans.
Bart teaches us how cars work by blowing stuff up and cutting things in half. It’s a science show for the car lover who’s easily bored. Join Bart as he explains the science behind everything automotive. This is cars down to the atom. This is Science Garage.

Being in school to become an aircraft mechanic, I've learned boxer engines are extremely prominent in general aviation (Cessna & Piper sized). Almost all small planes use boxers for harmonic balancing, and it makes it easier to pull off and swap cylinders out and rebuild the motors.

I used to work on inline opposing 4 and 6 cylinder engines. The big 6's had a C. I. D. of 560 and all the big 6's had these two (sometimes 4) "tabs" on the crankshaft for counter weights. They didn't always have counter weights, but they all had those "tabs. " The pistons diameter were like cantaloupes. And the wrist pins weren't pressed in or kept in place by snap rings. They had these little aluminum plugs with the cylinder walls at one end ("top" of the plug) and the wrist pin at the other (the plugs "bottom".....and now I think about it, sounds dirty).
