Our profession, the development of CNG bi-fuel powertrains


National CNG based engine (EF7)


This engine is designed to have optimal performance with natural gas (CNG) as a first fuel and gasoline is considered as the second fuel in it. The EF7 engine has a maximum power of 103 hp and maximum torque equal to 137 Nm with the use of CNG fuel and can fulfill the EURO 5 emission level. The new technologies which is used in the design and manufacturing of this engine are as follows:

  • High pressure gas injection technology
  • Using optimal compression ratio
  • Using Continuous Variable Valve Timing (CVVT) technology
  • Equal durability in using either fuels (CNG or Gasoline)

Why should CNG be used?

Lower fuel costs



CO2 emission rate

Lower particulate number (compared to gasoline)
