context_page_description: IKCO EF engines are a family of four-cylinder engines. The EF7 series are designed jointly by Iran Khodro Powertrain Company 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 aims to supply 800,000 powertrains by 2010.
  The first phase of IKCO EF Engines project investments were about 80 million US$.
  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 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.
context_section_description: Reaches maximum power at 6000 rpm and the maximum the torque at 3250 rpm in both CNG and petrol using conditions.
  IKCO has indicated an engine timing belt change interval of 180,000 Km. IKCO states if the engine runs only on CNG it will not need any special maintenance until 250,000 km(average) and if the engine runs with both CNG and gasoline the number will increase to more than 250,000 km.
  Due to lack of possibility and so many requests for single-fuel Samand with EF7 engine and lack of readying the EF7 Petrol-Based engine, In late 2009 IKCO wanted IP-CO to start a project for removing CNG-necessary parts of the engine. So the project done in about 3 months and tests completed in 2nd quarter of 2010. In this version of engine, only ECU Program is changed & CNG functions are disabled; This ECU program supports immobiliser too. Currently, consumers are able to purchase Samand EF7 single-fuel.
  In September 2010, IKCO announced the design and production of a modified EF7 engine with reduced fuel consumption & air pollution. The engine is mobilized with Direct Injection technology for both petrol & CNG.
  
  As the IPCO president says after the new engine is produced, IKCO will be the first manufacturer in the world using the Direct Injection technology for CNG engines.
