Case Studies by Alternate Fuel Centre

Gaseous fuel engine Completed project summary so far (1996 to as on date)

ARAI is working on alternative fuels including development of gaseous fuel since 1992 and successfully completed more than 100 projects for Indian OEMs and majority vehicles are plying on Indian roads.

In a view to minimise emissions, enhance efficiency and reduce oil imports, ARAI developed more than 30 dual fuel engines for off-road vehicle application including
2- wheeler, 3-wheeler, passenger car, LCV, HCV and off-road application like tractor, construction vehicle, Genset, etc. OEMs showed interest to develop the dual fuel engine using the piston, power cylinder, piston cooling, port type or vehicle-driven pump, etc. The challenge in dual fuel engine is the limit of power to achieve the required performance due to limitation of the proportion of diesel substitution. ARAI designed the dual fuel combustion system by evaluating injection timing, exhaust system and after- treatment design. In order to increase the mixing efficiency and exhaust-after treatment temperature, the exhaust routing has been changed so that the air and fuel will improve the combustion process inside the combustion chamber, and to lower the treatment of the engine-out pollutants.

Case Studies by Alternate Fuel Centre

Vehicle Type Vehicle Type Engine Capacity Emission Norms
2 Wheeler 1 100 – 150 cc engine BS IV to BS VI
3 Wheeler 9 0.1 – 0.6 L engines BS IV to BS VI
Passenger Car 13 1 – 1.4 L engines BS IV to BS VI
LCV 5 2.5 – 4 L engines BS IV to BS VI
SUV 3 2.5 – 4 L engines BS III to BS IV
SCV 1 1.5 L engine BS VI
HCV 9 3 – 6 L engines BS III to BS VI
Off Road 2 3 – 6 L engines Trem – II A

Development of BSVI Compliant CNG Engines

ARAI has demonstrated BSVI emission compliance along with OBD on 4 different engine models.

Key Highlights:

  • SPII and MPII fuel systems
  • Optics controlled Piped EGR
  • Unique after treatment system design
  • Exhaust temperature optimization to meet catcon placement need – more than 1.0 m away from exhaust manifold

Development of Duel Fuel Engine/Vehicle

ARAI has recently developed indigenous technology for conversion of existing diesel engine/vehicle to operate on dual (Diesel+CNG) mode.

  • Dual fuel is a viable technology for India from the point of view of emission reduction.
  • Economics of operation.
  • Flexible in operation.
  • All diesel-based customers / engines can be converted to it
  • Norms for dual fuel engine certification is notified

Development of Duel Fuel Engine/Vehicle

In diesel ethanol can’t be mixed however ARAl successfully developed additives due to which it is possible to mix ethanol diesel. The various blends 5% to 15 % blend of ethanol in diesel were optimized and 7.7% ethanol blend found suitable.
