// CORE INNOVATION
The patented Constant Volume Spark Ignition Engine based on the advanced RAVIKESH thermodynamic cycle.
An advanced modification of the conventional Otto cycle designed to maximize constant-volume heat addition and improve combustion energy utilization — India's proprietary thermodynamic innovation.
Fuel-air mixture combustion during minimal piston movement conditions, significantly improving combustion efficiency and reducing energy loss.
~15% reduction in total heat-exposed surface area and ~40% reduction in combustion chamber surface area at TDC, dramatically reducing thermal losses.
Innovative architecture designed to eliminate lateral piston forces, reducing friction losses, improving mechanical efficiency and increasing engine life.
Advanced variable compression ratio mechanisms for optimizing engine performance under varying operating conditions and fuel types.
Full support for gasoline, ethanol blends (E20, E85), and future sustainable fuels — preparing India's mobility for a sustainable fuel future.
