IKCO EF engines
IKCO EF Engines (also called National Engines) are a family of four-cylinder engines by the Iranian car manufacturer Iran Khodro (IKCO). The first engines of 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 IKCO EF Engines project (EF7 Dual-Fuel) investments were estimated at 80 million US$. IKCO aimed to supply 800,000 powertrains by 2010.
EF engines share most of their parts between them. The EF4 and EF7 are bi-fuel engines that use CNG as their main fuel and can also use gasoline. The EFD is a single-fuel engine that uses diesel as fuel.
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 alterations.
Some prominent suppliers for EF engines are INA for sensitive variable valve timing (VVT) parts and other mechanical parts, MAHLE which supplies some mechanically integral components of the engine family such as pistons, with Bosch supplying the ECU and electrically controlled pedal and many other sensitive electronic parts. All of the parts (except high-tech and sensitive parts) from worldwide companies are produced in Iran under license.
