Subaru 3rd gen boxer engine

[img]http://www.tune86.com/sites/default/files/subaru3rd-genbox_0.jpg[/img] Subaru first deployed its horizontally opposed Boxer engine back in 1966. Twenty-three years later, the second-generation Boxer debuted in the 1989 Legacy. Now, after 21 years of success, Fuji Heavy Industries Ltd. (FHI), parent company of Subaru, is ready to reveal the third-generation Boxer engine. Third-generation improvements are aimed at improving fuel efficiency and driving performance. This all-new Boxer mill features a lengthened stroke, a compact combustion chamber, optimized intake ports and employs an EGR (exhaust gas recirculation) cooler. Additional modifications include the use of lightweight internals, an AVCS (active valve control system), improvements to the cooling system and a compact oil pump. The third-generation Boxer engine maintains all of the benefits of the horizontally-opposed layout: compact, low center of gravity and lack of vibration, but the mill now boasts a claimed 10-percent improvement in efficiency and the ability to meet looming emissions standards. FHI will build the latest Boxer engine at its newly-constructed factory within the confines of its Gunma Oizumi Plant. [Source: Fuji Heavy Industries]
