Can CV Engine Kill Electric Cars

The video you provided details the concept and claimed advantages of the Constant Velocity (CV) Engine—a revolutionary internal combustion engine (ICE) design developed by the Indian company Ahiravata, in collaboration with CV Technologies.

The Problem with Traditional Engines

The video begins by noting that the conventional crankshaft engine design, which has been in use for over 230 years, suffers from two primary, unresolved issues:

Emissions (Pollution): The combustion process produces smoke and harmful emissions.
Low Energy Efficiency: A significant amount of the fuel’s energy is wasted—as much as 70% to 80% is lost to heat and exhaust instead of being converted into mechanical power.

CV Engine: The Core Innovation

The CV Engine, also internally nicknamed the ‘Flower Engine’, is designed to solve these issues by eliminating the traditional crankshaft.

Feature	Conventional Engine (Crankshaft)	CV Engine (Rod Rack System)
Power Conversion	Crankshaft converts reciprocating motion to rotary motion. Maximum power transfer occurs for a brief moment near mid-stroke.	A Rod Rack and Power System replace the crankshaft.
Piston Movement	The piston’s connecting rod tilts, causing friction (side load) on cylinder walls.	Pistons are fixed onto a solid Rod Rack, moving in perfect linear alignment with no tilt.
Torque Loss	Approximately $40\%$ of torque is lost when the piston is at Top Dead Center (TDC).	The Rod Rack system prevents this power loss.
Piston-Cylinder Contact	Direct contact, requiring oil in two-stroke fuel.	No direct contact, allowing it to run in two-stroke or four-stroke without oil in the combustion chamber.

Performance and Efficiency Claims

Ahiravata claims the CV Engine achieves dramatically improved performance and efficiency:

Increased Power and Torque: The engine generates 40% more power and achieves up to 90% stroke power, resulting in a 58% increase in power output overall.
Reduced Size and Fuel Use: The engine’s physical size is cut in half. For example, a 2500 cc engine producing 170HP can be replaced by a 450 cc CV Engine that produces 193 HP at half the RPM, while using 58% less fuel.
Lower Emissions: It achieves a 71% reduction in emissions.
Enhanced Durability: The elimination of piston side load and the reduction in internal pressures and friction are predicted to reduce wear on internal components, leading to less maintenance and a longer engine lifespan.

Versatility and Future Potential

Fuel Types: The engine is capable of running efficiently on cleaner fuels such as Ethanol, CNG, and Hydrogen.
Hybrid Design: The power shaft is hollow, which allows a second engine or an electric motor to be mounted directly behind it. This makes the design highly suitable for hybrid vehicles.
Current Development: Ahiravata is currently working to introduce this engine technology first in a two-wheeler and a three-wheeler.

Constant Velocity (CV) Engine (a term used for a new generation of internal combustion engine technology), an innovation that aims to fundamentally redesign how the piston’s force is converted into power. This technology is not to be confused with the Constant Velocity (CV) joint, which is a common part of a car’s drive axle. The CV Engine proposes a revolutionary change at the very heart of the engine block.

While still a developing technology aiming to challenge the two-century dominance of the crankshaft engine, the Constant Velocity Engine represents a compelling look at how fundamental mechanical engineering can still lead to revolutionary breakthroughs in power, efficiency, and environmental sustainability in the automotive world.
