Aftertreatment system for diesel vehicle exhaust based on Freescale MCU

Aiming at the scarcity of aftertreatment system for diesel vehicle exhaust in our country,on the basis of the principle and control requirements of aftertreatment for diesel vehicle exhaust,a new aftertreatment system was designed with the core of MC68HC908EY16.The anti-interference of the system was introduced in components choosing,circuit designing and software processing.The system functions of signal sampling,data computing and analyzing and exhaust regeneration were also introduced.The debug results show that the system works well,and the effect of exhaust purifying is achieved.
