Scr system fault what is going on with this truck and how can it be fixed asap ...evaluated each technology and concluded that SCR will provide the most fuel efficient and cost-effective solution to 2010 regulations. The SCR system operates downstream from the engine, removing much of the stress and heat rejection related to EGR-only engines to improve reliability and increase fuel economy. How Does SCR Work? SCR is very simple.The simpler strategy of locating the catalyst close to the engine increases the amount of heat transferred to the SCR system. However, it may cause thermal sintering and thermal ageing, which reduce the SCR system's lifetime. In addition, high temperatures compromise the efficiency of SCR systems [15], [17].The SCR's job in the Emissions After-Treatment System (EATS) is to lower the NOx level emitted into the atmosphere. The performance of the SCR is evaluated by the NOx sensors. There are NOx sensors that are located on upstream (inlet) and downstream (outlet) ends of the SCR. Important: the SCR is the last component in the EATS which makes
