Vehicle converted to CNG:

• No Power Losses and follows the torque curve of Diesel Euro IV/VI compatible based on bus engine selected Simple and Compact.
• Optimum fuel economy due to better fuel control.
• Repeatability and Reliability of performance.
• No compromise in Drivability and Pick-up.
• Easy diagnosis. Self-Diagnosis system.
• Easy to install and calibrate.
• Based on vehicle selected long range can be achieved.
• In the unlikely event of failure to demonstrate performance bus can be reconverted to diesel.
• Provide warranty period service and support assurance based on routes where buses would operate apart from training local staff for any minor work.
• Can take service contract and support with spares and service based on the routes bus would operate.
• Based on the number of buses converted by us, an engineer can be stationed at one of the depots.

Range & Comparison

1. Assuming that fuel efficiency is 4 Kms/kg of CNG.
2. Frames, piping, valves, supports, cabinet are designed for minimum weight.
3. Lower weight means better fuel efficiency, better safety, lower cost of design.

Focus Areas

Double Decker CNG System

Simplified Plumbing

Lightweight and Safe Rooftop CNG Systems

ProCab & ProRail CNG Systems

LNG Points to Note

• Natural Gas when liquified is LNG and when compressed is CNG.
• When space on vehicle is low, range required is long then LNG can be a good option.
• If however space is not a constraint, based on duty cycle LNG or CNG can be decided.
• Vehicle efficiency does not change in either case For a similar.
• The only issue with LNG is that if the vehicle is not on regular/ continuous duty cycle the gas will boil off/vent and fuel is lost.
• Professionally choice of fuel on any automobile must be based on vehicle design/ structure, range required and duty cycle & this can be a combination of LNG or CNG in a fleet.

Broad list of works

Type 4 Cylinders

Benefits of T4 Composite Cylinders

• Latest technology in the world.
• Technology history since 1963 & commercial history since 1993.
• Lightweight – 70% LOWER in weight than Steel.
• For comparable weight & capacity system cost is competitive.
• Zero rusting or corrosion.
• Zero damage against Chemicals/ UV/Impurities found in natural gas.
• International practices do NOT specify periodic hydraulic retesting – only visual inspection needed.
• Infinite fatigue life.
• Demonstrated safety in mission critical applications like Space Shuttle.
• Behaviour of T4 Cylinder in a fire very different than Steel – much higher safety.
• High impact strength.
• Burst pressure of 550 bar & above for operating pressure of 200 bar.
• The low weight combined with efficient system design gives options of long range travel for both bus and truck applications.
• No risk of metal embrittlement when used with Hydrogen.
• Lifetime cost lower than steel, system cost comparable to steel.

Commercials – Lower Cost

The benefits of this solution is in the system design in terms of:

• Lower weight.
• Lower cost of assembly.
• Lower cost due to minimum piping.
• Lower risk of leak points.
• Lower maintenance cost.
• Lower recertification cost.
• Lower risk on safety due to visual inspection as per international standards.
• Lower cost of bus structure itself owing to low system weight.
• Lower cost to provide brakes, suspension etc. to cater to higher weight.
• Designing vehicles for new applications & markets.
• Meeting the planned emission norms of Euro/Bharat 6 today.
