innovation in green engine technology would cover the development of new, high-efficiency, low-emission internal combustion engines (ICEs) and alternative propulsion systems to address global energy and environmental challenges. It would highlight breakthroughs in advanced engine design, fuel usage, and manufacturing techniques aimed at maximizing performance while minimizing the environmental impact. Advanced internal combustion engine (ICE) design Pistonless engines: Revolutionary designs, such as the six-phase green engine, eliminate traditional pistons in favor of rotating vanes and rotors. This unique structure allows for a higher expansion ratio and a six-phase cycle—intake, compression, mixing, combustion, power, and exhaust—which increases efficiency and significantly reduces emissions. Variable compression ratio: This innovation allows the engine to dynamically adjust its compression ratio for the most suitable operating mode, leading to excellent combustion performance across different driving conditions and fuel types. Constant volume combustion: Also known as isobaric combustion, this process keeps volume constant during combustion, enabling higher power generation and more stable, controlled burning. This reduces heat loss and nitrogen oxide (NOx) emissions, particularly during lean-burn operation. Direct air intake and fuel injection: Removing throttles and valves from the intake system reduces pumping losses and improves volumetric efficiency. Paired with direct fuel injection, this ensures higher torque, faster acceleration, and more efficient fuel-air mixing, which helps eliminate carbon monoxide (CO) emissions.
