Maximum Energy Extraction from Every Combustion Event
Constant Volume Heat Addition is the core combustion principle behind the CVSI Engine. By ensuring fuel-air mixture burns while the piston is at minimal movement, the CVSI Engine extracts maximum energy from every combustion cycle.

Section 01
When fuel burns at constant volume — meaning the piston barely moves during combustion — all the heat energy generated increases the gas pressure rather than being partially wasted. This is the same principle that makes diesel engines efficient, but applied to spark ignition engines for the first time through the RAVIKESH Cycle architecture.
Section 02
In standard SI engines, the piston is already moving downward when peak combustion pressure is reached. This means a significant fraction of combustion energy is lost to heat transfer through cylinder walls and pumping losses. The CVSI Engine's geometry and timing system ensures the piston is near stationary when maximum combustion pressure occurs.
Section 03
Achieving constant volume heat addition requires a precise combination of engine geometry, valve timing, ignition timing control, and combustion chamber design. KunwarMotors has engineered all these elements together in the CVSI platform, creating a system where the combustion event is compressed into the smallest crank angle window possible around TDC.
