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.
[5] [6] The most common design of flat engine for motorcycles is the boxer-twin, beginning with the 1905 Fée flat-twin engine, manufactured by the Light Motors Company, which was the first production motorcycle engine. [7] BMW Motorrad have a long history of boxer-twin motorcycles, beginning in 1923 with the BMW R32 [5]
Unlike prior Subaru flat-6 designs, the EZ30 has a significantly smaller bore pitch (the distance between adjacent cylinder centerlines on each bank of the engine block) than the contemporary flat-4 EJ-series. The bore pitch of the EZ30 is 98.4 mm (3.87 in), [36] compared to a bore pitch of 113 mm (4.4 in) in the EJ series.
The Porsche flat-six engine series is a line of mechanically similar, naturally aspirated and sometimes turbocharged, flat-six boxer engines, produced by Porsche for almost 60 consecutive years, since 1963. [8] [9] The engine is an evolution of the flat-four boxer used in the original Volkswagen Beetle. [10] [11] [12
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 ...
"Flat" does not specify crankshaft design and therefore can refer to either a non-boxer engine like the Ferrari or a true boxer engine like a Porsche flat-6. Alternatively, some sources prefer to call Ferrari flat-12 engines a "180° V12", referring to the V12-derived crankshaft design and the 180° angle between cylinder banks. [3]: 60 [4]: 8 ...
The base engine is a 2.7-litre 176 kW (239 PS; 236 hp) flat-six boxer engine, with the Boxster S getting a 3.2-litre 206 kW (280 PS; 276 hp) engine. For 2007, the base Boxster received a revised engine featuring VarioCam Plus and the Boxster S engine was upgraded from 3.2-litre to 3.4-litre.
