Шаблон:Infobox automobile engine
The Hyundai Alpha series is a multi-valve gasoline inline four-cylinder engine family comprising 1.3, 1.4, 1.5, and 1.6 L naturally aspirated versions and a 1.5 L turbocharged version. Introduced in 1992, this was Hyundai's first engine designed entirely in-house and was the first indigenous South Korean engine design. Design objectives were to provide high performance and good fuel economy with excellent durability at a reasonable cost.[1]
The first Alpha series engine marketed was the 1.5L SOHC 12-valve inline-four. It was offered in naturally aspirated and turbo versions and debuted in the 1992 Hyundai Scoupe. A 1.3L version debuted later in the Hyundai Accent.
A dual overhead camshaft (DOHC), four valve per cylinder version debuted in the 1996 Hyundai Accent GT.
A strengthened block, an eight-counterweight crankshaft, and hydraulic engine mounts were added from 2000-onward to reduce NVH (noise, vibration and harshness).
The 1.6L Alpha II debuted in 2001, eventually replacing the 1.3L and 1.5L. It was further revised in 2005 with a 1.4L version also debuting. Notable improvements over the Alpha included a DOHC 16-valve cylinder head, graphite-coated piston skirts, a strengthened cylinder block, ribbed aluminum oil pan, coil-on-plug ignition, an enlarged throttle body (increased from 48 mm to 52 mm), a revised PCM (powertrain control module), simplified and shortened intake ducting, a revised intake manifold, and a returnless fuel system. These improvements further reduced NVH and emissions, with the 1.6L version becoming ULEV-certified in all 50 U.S. states.
