The Hinduja Group flagship, Ashok Leyland, says it is the first company in India to receive the OBD (On Board Diagnostic) II certification for BS IV-compliant commercial vehicle engines for CNG technologies, SCR (Selective Catalytic Reduction) and EGR (Exhaust Gas Recirculation). OBD II certification will be a legislative mandate from April 1st, 2013 as part of the BS IV regulations on all commercial vehicles that have come into force.
“This is one more triumph of innovative Indian engineering,” is how Mr. Vinod K. Dasari, Managing Director, Ashok Leyland described the achievement. “With the introduction of stricter emission norms, there is a greater need for more sophisticated emission control technologies. While passenger car companies had a learning curve by graduating from OBD I to OBD II levels, we had the tougher task of going directly for OBD II certification and for having achieved it across all three technologies is why this is such a significant achievement for us.”
OBD is a system that detects failures that adversely affect emissions and illuminates a dashboard light known as the Malfunction Indicator Lamp (MIL) to warn the driver of the fault. The OBD aids diagnosis and repair of complex electronic engine controls, helps keep emissions low by early identification of controls that need repair, is a life-long solution for the vehicle while from an industry perspective encourages the design of durable emission control systems.
