# Revolutionary Combustion Engines This Engine Offers Phenomenal Power and Optimized Efficiency By Rahul Kalvapalle | Published 2024-06-13 | Autos Source: Trend Hunter, https://www.trendhunter.com/trends/combustion-engine References: [newatlas](https://newatlas.com/transport/avadi-rotational-engine-concept/) & [avadiengines](https://www.avadiengines.com/overview)  Avadi Engines has launched a high-tech combustion engine that is designed to offer high-level functionality without carrying all the complex parts of a conventional engine, allowing for a heady combination of high power and efficiency. This particular engine uses a [rotary valve mechanism](https://www.trendhunter.com/trends/mag-drive) wherein a pair of connecting rods and their pinion are situated inside a specialized chamber that is specifically designed to be able to translate the vertically aligned movement of the piston into rotation. While rotary engines are not altogether a new innovation, what makes the Avadi Engines' product unique is the complete absence of a crank shaft. Among the many impressive performance outputs of this particular combustion engine is a reported brake thermal efficiency that is just in excess of 42.12 percent, which is a significant improvement over the parameters boasted by [regular gasoline engines](https://www.trendhunter.com/trends/aircela).
