Designe of the New Iran National Engine- A balance between challenging demands of performance, cost and environmental friendliness

Nowadays with advent of new engine design technologies, Iran-Khodro felt to develp the new products with the new breeds of engines with ownership whereby on the market, it requires developing an engine family to cover a wide range of vehicle platforms. On the other hand the engine family must meet the contemporary fuel consumption, power and emission levels in acordance with the policies which are based on CNG rather than gasoline. To materialize this concept, design of the new Iran national engine project, named EF7 was set up. This is a survey to present the engine technical specifications and the objectives which could be realized throughout this project. We are also to feature the new emgine design challenges and effortss that the design teams struggled to achieve the targets. This is a long-term project in collaboration with IPCO and FEV hand in hand. After 15 months hard- working, 55 engine prototypes were produced successfully and we are confident the engine works the way it was supposed to.
