IKCO EF engines are four-cylinder engines. The EF7 series are designed jointly by Iran Khodro Powertrain Company (IPCO) and F.E.V GmbH of Germany. The other models will be designed by IPCO itself. IPCO is the powertrain designing & producing company of Iranian car manufacturer Iran Khodro (IKCO). IKCO aims to supply 800,000 powertrains by 2010. The first phase of IKCO EF Engines project (EF7 Dual-Fuel) investments were about 80 million US$.〔(carone.parsfa.com ) (Persian)〕〔(Iran Tejarat )(Persian)〕 EF4 & EF7 engines use CNG as their main fuel and they can also use gasoline. EFD is the first engine of the EF family that is single-fuel. It uses high-quality diesel (Euro 4 Quality or better) as fuel. EF engines share most of their parts between them. It was IKCO's aim to reduce costs and provide ease of supplying the parts in the future for after-sales services. The EF family dual-fuel and petrol-fuel engines have achieved the Euro IV emission standard and are able to achieve Euro V emission standard with some minor changes〔 but EFD will be the first engine of the family which comes with the Euro IV emission standard as its first release, and is able to achieve the Euro VI emission standard with some changes. The most important suppliers for EF engines are INA for sensitive VVT parts and some other mechanical parts, MAHLE which supplies some important parts of the engine family such as pistons, with Bosch supplying the ECU and electrically controlled pedal and lots of other important sensitive electronic parts. Almost all of the parts (except high-tech and sensitive parts) from worldwide well-known companies (as mentioned) are produced in Iran under license with the highest required quality for the engines. Also The German company Bosch had shown interest in assembling the Iranian engine under license. In 2008 IKCO has announced that EF7 is among the three best CNG-based engines of the world in designing.〔() 〕 ==EF7== The engine general structure is similar to the PSA Group's Peugeot TU5JP4. It has displacement of 1648 cc with a bore of 78.560 mm and a stroke of 85 mm. This engine was introduced as EF7 dual-fuel in 2008 at Engine Expo Stuttgart, Germany,. It is a 16-valve engine incorporating CVVT technology on its intake valves (IPS type). It features an advanced cooling system (both lubrication and liquid-cooling) compared to many same-level new engines worldwide and also compared to the PSA TU5JP4. The EF7 has a direct-drive oil pump.〔 The water pump, oil pump and oil coolant system are integrated in one place to reduce removal of parts for maintenance compared to other engines. Other parts are re-engineered to provide ease in changing the oil filter. The engines will use a Three way Catalytic Converter to reach higher emission standards.〔 All the EF7 variants have passed the NVH tests successfully on their head cylinder & cylinder block.〔 Also, the engines have a Blow-by system which does ventilation for the Crankcase and Oil Pan.〔 The EF7 assembly line is in Tehran, Iran. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「IKCO EF Engines」の詳細全文を読む スポンサード リンク
