CHENNAI: Ashok Leyland, the flagship company of the Hinduja group and Indian Institute of Technology Madras (IIT Madras) researchers at the National Centre for Combustion Research and Development (NCCRD) collaborated for development and commercialisation of ‘Swirl Mesh Lean Direct Injection (LDI) system’ technology for developing a series of hybrid Electrical Vehicles using this turbine technology.

IIT Madras Researchers at NCCRD are developing an indigenously-designed micro gas turbine, which will replace the large battery. At the core, is a patented combustion technology called ‘Swirl Mesh Lean Direct Injection (LDI) system.’

After the technology was demonstrated on a lab scale, Ashok Leyland signed a letter of support to develop this technology for the heavy vehicles segment with NCCRD, IIT Madras. As part of the collaboration, Ashok Leyland, handed over to NCCRD a 9-meter passenger electric bus on Monday.

V Kamakoti, director, IIT Madras, received the bus on behalf of NCCRD, IIT Madras, from N Saravanan, CTO, Ashok Leyland, and Kanakasabapathi Subramanian, SVP, Product Development, Ashok Leyland.

Saravanan said, “Micro Gas Turbines hold significant promise as a technology that will extend fuel combustion beyond traditional IC engines and provide for more efficient performance and multi-fuel capability"

Sathya Chakravarthy, Coordinator, NCCRD, IIT Madras, said, “This marks our conviction of not only working with the industry on innovative technological solutions of societal impact but also pushing the inhouse developments on innovation to see the light of day with the industry.”

Key advantages:

Overall lighter power train (high weight-to-power ratio),

Ultra-low emissions,

Multiple fuel capabilities (eg Biogas, CNG, LNG, Diesel, Hydrogen), and

Overall low cost of ownership
