Difference between two flat 6 cylinder engines: 180° V on the left, boxer on the right. The advantages of flat engines are a short length, low centre of mass and suitability for air cooling (due to the well-exposed, large-surface-area cylinders and cylinder heads, and their short length).
A flat-four engine, also known as a horizontally opposed-four engine or boxer engine, [1] is a four-cylinder piston engine with two banks of cylinders lying on opposite sides of a common crankshaft. The most common type of flat-four engine is the boxer-four engine , each pair of opposed pistons moves inwards and outwards at the same time.
The crankshaft configuration varies amongst opposed-engine designs. One layout has a flat/boxer engine at its center and adds an additional opposed-piston to each end so there are two pistons per cylinder on each side. An X engine is essentially two V engines joined by a common crankshaft. A majority of these were existing V-12 engines ...
A boxer-style flat-six engine is able to have perfect primary and secondary balance.As in other six-cylinder engines, the overlapping of the power strokes of the different cylinders (with a firing interval of 120 degrees in a four-stroke engine) reduces the pulsating of the power delivery relative to that of similar engines with fewer cylinders.
The Volkswagen air-cooled engine is an air-cooled, gasoline-fuelled, boxer engine with four horizontally opposed cast-iron cylinders, cast aluminum alloy cylinder heads and pistons, magnesium-alloy crankcase, and forged steel crankshaft and connecting rods.
The last flat-six-powered Porsche prototype was the Le Mans-winning 911 GT1-98. Since then, its prototypes have used V-4 and V-8 engines. Here's why.
The difference between this engine and a true ‘boxer’ is that on the Ferrari engine the corresponding connecting rods of each bank are coupled on the same crankpin, so the two pistons move in the same direction, whereas in a true boxer engine (for example the flat-six Porsche engine) the pistons move in opposite directions.”
