Researchers from IIT Delhi’s Department of Energy Science and Engineering (DESE), Indian Oil Corporation’s Research and Development (IOC R&D), and Ashok Leyland Ltd. have developed a technology that enables a diesel-powered automotive vehicle to operate in flex-fuel mode, i.e., 100 percent diesel or DME plus diesel.
Dimethyl Ether (DME) is a liquid fuel that can be used in place of compression ignition engines/vehicles. DME has a higher cetane number (58) than regular diesel (51). IIT Delhi, IOC R&D, and Ashok Leyland developed the technology.
- Researchers from IIT Delhi’s Department of Energy Science and Engineering, Indian Oil Corporation (IOC R&D), and Ashok Leyland Ltd. have devised a technique that allows a diesel-powered vehicle to run on 100% diesel or DME plus diesel.
- The researchers used this method to transform a diesel vehicle into a flex-fuel vehicle.
- Dimethyl Ether (DME) is an alternative fuel for compression ignition engines/vehicles (51).
- “DME fuel is pumped into the engine’s intake manifold, while diesel is directly fed into the engine cylinder,” stated Prof. K. Subramanian, Head, Department of Energy Science and Engineering, IIT Delhi.
- Highlights of IIT Delhi, IOC R&D, and Ashok Leyland technology:
- FFV Technology (Vehicle can run both modes: either 100 percent diesel or DME-Diesel mode)
- In the first phase, flex-fuel vehicles are used; in the second phase, 100% DME/alternative fuel vehicles are used.
It can run on either 100% diesel or Dimethyl Ether (DME) plus diesel. This technology was created by researchers from the IIT Delhi’s Department of Energy Science and Engineering, Indian Oil Corporation (IOC R&D), and Ashok Leyland Ltd. There was money for the project from the Department of Science and Technology (DST), the government in India.
It took a diesel-powered car and turned it into a flexible fuel car for a test run. DOST, a flex-fuel technology-based vehicle, was jointly launched on April 8, 2022, at IIT Delhi by Dr. Srivari Chandrasekhar, Secretary of the Department of Science and Technology; Prof. Rangan Banerjee, Director of IIT Delhi; Dr. SSV Ramakumar, Director (R&D), IndianOil; Shri. Krishnan Sadagopan, Senior Vice President, Ashok Leyland; Prof. Sunil Kumar Khare, Dean R&D, IIT Delhi; Prof. K. A. Subramanian, Head, DESE, IIT Delhi; and other senior officials from IIT Delhi, IOC R&D, and auto major Ashok L, among others.
Indian Institute of Technology Delhi came up with the flex-fuel engine technology that can run on DME. IOC R&D did endurance and field tests, and Ashok Leyland helped them make the engine oil.

Dimethyl Ether (DME) is one of the fuels that can be used in compression ignition engines and vehicles because it has a higher cetane number (58) than diesel (51). There are many ways to make DME: You can make it from Biomass, Coal, Industrial Waste, Municipal Solid Waste, and Black liquor, which is a byproduct of pulp, by gasifying and using the Fisher-Tropsch process. Then, it can also be made through the dehydration of methanol with the help of a catalytic process. If you live where the temperature and pressure are right, DME could easily change from liquid to gas.
During a discussion about flex-fuel vehicles, Prof. K. Subramanian, the head of the Department of Energy Science and Engineering at IIT Delhi, said that “DME fuel is injected into the engine’s intake manifold, and diesel is injected into the engine cylinder.” The CRDI system controls diesel and DME fuel injection based on how much power the car needs. There is no sound from the engine or the car when it runs at the right DME energy share without a hitch.” It was made by IIT Delhi, IOC R&D, and Ashok Leyland. These are some of the most important things about technology.
Technologies that make cars that can run on different kinds of fuel (Vehicle can run both modes: either 100 percent diesel or DME-Diesel mode)
They were transitioning diesel trucks from diesel to DME as an alternative fuel (first as a Flex Fuel Vehicle, then a 100% DME/alternative fuelled vehicle).
