CNG Conversion Options..1

Bi-Fuel

  • There is no basic change in the Diesel Engine.
    The FI pump is recalibrated generally to 30% of original capacity and additional 70% supply of natural gas replaces the reduced amount of Diesel.
  • Actual Gas/Diesel consumption is generally 50:50
  • Emission controls are not good due to Diesel burning.
  • Cost of conversion is generally more
  • Maintenance costs are higher as although the conversion is simpler but the system requires frequent adjustments afterwards.

 

CNG Conversion Options..2

Dedicated CNG

  • The engine configurations are changed to accommodate lower compression ratio, spark ignition system and closed-loop fuel control system.
  • The engine runs on CNG only
  • Emission levels are near zero
  • Cost of conversion is lesser
  • Maintenance costs are lower as although the conversion is more complex but the system does not need frequent re-adjustments.
