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.
