Fixed combustion volume, Long propeller shafts, frictional moving parts, and high-temperature combustion are key characteristics of internal combustion (IC) engines. These factors contribute to low mileage, high maintenance costs, unburnt fuel, harmful emissions, and excessive noise and vibration. While traditional IC engines require numerous additional components to mitigate these issues, solutions are often incomplete and costly. In contrast, the intrinsic nature of our propreitary Dual free Piston Linear Engine (LSync) engine effectively addresses these challenges without the need for extra components, delivering a more efficient and cost-effective solution.
