2. Development of Air Purification Technology for Internal Combustion Engines
The Warp Air Clean product, developed in collaboration with our laboratory is compact, requires no changes to vehicle or engine structures, and can be easily installed in front of the vehicle’s air filter. This technology can reduce HC and CO emissions by 80%, black smoke emissions by 20-80%, diesel fuel consumption by 6-10%, and gasoline fuel consumption by 10%. With a lifespan of 2 years, the product’s fuel savings can recover the cost within 6 months, providing significant environmental and economic benefits.

3. Development and Application of a Flying Intelligent Environmental Monitoring Robot
The flying intelligent environmental monitoring robot, developed by the laboratory after over 10 years of research, integrates theoretical algorithms, multi-source sensors, big data, and unmanned aerial vehicles (UAVs), and has already obtained 11 intellectual property rights. Unlike drones that only take photos, this product is a new generation flying robot with eyes, a brain, and a soul, driven by our innovative theoretical algorithms. The product is expected to significantly replace human labor in many industries and fields, becoming a norm in society and workplaces.
