The CRDI (Common Rail Direct Injection) Engine Test Rig, manufactured by Atto Labware, is a specialized training system for studying the operation and performance of modern diesel engines equipped with common rail fuel injection technology. It allows students to conduct performance tests, analyze fuel injection parameters, and understand the advantages of CRDI systems over conventional diesel engines. Mounted on a robust mobile workstation, the system integrates advanced sensors, instrumentation, and safety features, making it ideal for automotive engineering programs, research labs, and technical institutes.
