Theta II 2.0L Theta II engine (G4KD) in a Kia Sportage ![]() The 2.4L version is an inline 4-cylinder engine that carries a bore of 88.0 mm, stroke of 97.0 mm and a 10.5:1 compression ratio the engine dry weight is 146 kg (322 lb) and it makes 165 PS (121 kW 163 hp) at 5,800 rpm and 22.3–23 kg⋅m (161–166 lb⋅ft 219–226 N⋅m) of torque at 4,250 rpm. It uses a timing chain instead of belt, and the engine dry weight is 134 kg (295 lb). The first version of the Theta Engine had three variants, 1.8L, 2.0L and 2.4L. Theta's EMS ( engine management system) software is EMS-II from Siemens VDO and the 32-bit PCM (Powertrain Control Module) calculates the amount of intake air by utilizing a contamination-proof hot-film type MAF ( mass air flow) sensor. Other notable features include fracture-split sinter-forged connecting rods manufactured by Sinteron and a stainless-steel exhaust manifold. In the lower-end, the block is reinforced by a ladder frame. The aluminum alloy engine block, which is formed using a high-pressure die-cast method, has a unique Metaldyne-supplied cassette-type balance shaft module with a two-stage oil pump built-in. Continuously variable valve timing (CVVT) works on the intake side. BorgWarner Morse TEC supplies the complete timing system which uses the company's proprietary silent timing chains. The engine features hollow stainless-steel dual overhead camshafts ( DOHC) with powder-metal cam lobes, pent-roof combustion chambers and shimless bucket tappets in the cylinder head. In 2009, Chrysler bought out Mitsubishi and Hyundai's stake in the joint-venture however, each company retained rights to build the engines. Each manufacturer configured their variants of the initial design differently based on their needs. The Global Engine Alliance was a joint venture between Chrysler, Mitsubishi Motors, and the Hyundai Motor Company for developing a line of shared four-cylinder engines. Hyundai Motor Manufacturing Alabama (HMMA) built a Theta II engine shop on the grounds of their Montgomery, Alabama automobile factory. The third all- aluminum engine of Hyundai Motor Company debuted in the fourth-generation Hyundai Sonata sedan (codenamed NF), which was unveiled in August 2004 in South Korea. The Hyundai Theta is a gasoline four-cylinder automobile engine family. Reciprocating internal combustion engine θ engineġ6.9–40 kg⋅m (166–392 N⋅m 122–289 lbf⋅ft)
