Key Characteristics - CNG & LPG Applications

CNG Applications LPG Applications
1 Kg CNG = 1.5 Ltr Petrol 1 Ltr. LPG = 0.95 Ltr. Petrol
Power Loss 4 to 11 % Almost equal to Petrol
Tank Weight is very high Tank weight is low
Frequent Re-Fueling intervals Long intervals for Re-Fueling
Initial kit cost expensive Initial kit cost low
Clean Fuel Technology Comparatively low quality [better than Petrol]
125 to 130 Octane Fuel 105 to 110 Octane fuel
Cheaper running cost Running cost higher compare to CNG
Specific to commercial application Specific to individual applications
Fuel delivery concepts

Close loop injection valve feed method in sequence manner

Close loop venturi feed fuel delivery method

The Sequent Serial management system…

The system based on the BRC’s long experience in the designing and construction of LPG & CNG gaseous injection systems, the new multipoint sequential system constitutes the peak of the current technology in the field of the gaseous injection for running engines at a controlled fuel delivery & ignition.

Current features of the system are not to meet only mandatory emission norms but to meet higher technological requirement in all manner of current automobile.

Only company to have an ISO 15500 certificate for Gas Injectors through undergone the test cycle of 600 Million

Mitsubishi Cedia 2.0 Ltr., Euro-3 CNG Emission Cycle V1 Result with BRC Sequential Injection Feed System
   
Sequent Homologation In India
 
Rohan Automotive is the first company in India to complete the homologation at ARAI with LPG Sequential Injection System The system has been installed on Toyota Innova and converted the vehicle as a duel fueled [Petrol + LPG] variant submitted to ARAI for Eur
III Homologation. The vehicle has achieved Euro-III Emission V1 limit & Power loss of 1.5% compare to Petrol.
   
Sequent Application In India
Rohan Automotive is the first company in India to install LPG-CNG Sequential Injection System
The Mitsubishi India has chosen the BRC Sequential CNG & LPG System for Mitsubishi Cedia Alternate Fuel Variants. The vehicles are under endurance test and shortly will be submitted to ARAI for the homologation.
