Development of a flex-fuel spark-ignition engine for utilization of green hydrogen-CNG blended fuels

Objective

• To develop a flex-fuel gaseous engine setup to efficiently utilize hydrogen-CNG blends in a spark-ignition engine and optimizing the engine design and operating parameters, To develop an electronic port fuel injection system with an in-house developed ECU, capable of tracking crank angle resolution of 0.1 CAD, Training sessions on the developed flex-fuel gaseous engine setup with electronic port fuel injection and in-house developed ECU for effective dissemination of knowledge for wide adoption of green hydrogen mobility to meet national green hydrogen mission.

Description

• A multi gaseous-fuels blending setup will be developed to blend up to three individual gases and obtain desired mixture composition readily available for engine experimentations. The developed fuel blending setup would be compatible to incorporate highly reactive fuels like hydrogen. The readily available desired gas (as per the composition) in the buffer chamber can be supplied to the intake manifold through an injection system.

Impact

• 1) Nation will be benefited, since the proposed use of green hydrogen will promote the achievement of required emission targets for decarbonisation and it is also aligned with the recent interest of Indian government related to National Hydrogen Energy Mission, 2) Automotive and power generation industry will be benefitted since the proposal addresses the challenges faced by these industries to step into hydrogen economy and achieve environmental targets, 3) General public are the end users and major beneficiaries of technical developments, hence the same will be beneficial for the general public, 4) People and Planet ? by contributing to Sustainable Development Goals (SDGs) set by the United Nations; and specifically ? affordable and clean energy, sustainable cities and communities, responsible consumption and production, and climate action.
