// CORE INNOVATION

CVSI Engine Technology

The patented Constant Volume Spark Ignition Engine based on the advanced RAVIKESH thermodynamic cycle.

01
🔬

RAVIKESH 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.

02
🔥

Constant Volume Heat Addition

Fuel-air mixture combustion during minimal piston movement conditions, significantly improving combustion efficiency and reducing energy loss.

03
❄️

Reduced Heat Loss Architecture

~15% reduction in total heat-exposed surface area and ~40% reduction in combustion chamber surface area at TDC, dramatically reducing thermal losses.

04
⚙️

Zero Lateral Piston Force

Innovative architecture designed to eliminate lateral piston forces, reducing friction losses, improving mechanical efficiency and increasing engine life.

05
📊

Variable Compression Ratio

Advanced variable compression ratio mechanisms for optimizing engine performance under varying operating conditions and fuel types.

06
🌿

Flex-Fuel Compatibility

Full support for gasoline, ethanol blends (E20, E85), and future sustainable fuels — preparing India's mobility for a sustainable fuel future.
