IKCO EF Engines (also known as National Engines) are a family of straight-four engines produced by the Iranian car manufacturer Iran Khodro (IKCO). The first engines in this family, the EF7 series, were designed jointly by Iran Khodro Powertrain Company (IPCO) and F.E.V GmbH of Germany. The later models were designed by IPCO alone. IPCO is the powertrain design and production company of IKCO. The first phase of the IKCO EF Engines project, the EF7 dual-fuel, had an estimated cost of US$80,000,000 and aimed to supply 800,000 powertrains by 2010. Most EF engines share a set of common parts. The EF4 and EF7 are bi-fuel engines that primarily use compressed natural gas (CNG) but can also operate on gasoline. The EFD is a single-fuel diesel engine. The EF family dual-fuel and petrol-fuel engines have achieved the Euro IV emission standard and can achieve the Euro V emission standard with some minor changes. EFD will be the first engine of the family already conforming to Euro IV emission standard at initial release, and will be capable of attaining the Euro VI emission standard with alterations. Some prominent suppliers for EF engines are INA for critical variable valve timing (VVT) and other mechanical parts; MAHLE, which supplies some integral components of the engine family such as pistons; and Bosch, which supplies the ECU, electrically controlled pedal (Drive by wire), and many other sensitive electronic parts. All parts (except high-tech and sensitive parts) from worldwide companies are produced in Iran under license.
