DAMAGE
When the impurity content is too high, the SCR system cannot function properly.
The exhaust after-treatment device is blocked, causing a decrease in vehicle power.
Urea easily crystallizes and blocks the SCR nozzle.
SCR system malfunctions increase maintenance costs.
Low exhaust conversion rate fails to meet emission requirements.
(SCR) systems
These five issues are common problems associated with selective catalytic reduction (SCR) systems used in diesel engines. High impurity content in the fuel or exhaust can cause the system to malfunction, while a clogged aftertreatment device can lead to reduced vehicle power. Urea, which is used in the SCR process, can crystallize and block the nozzle. A malfunctioning SCR system can result in increased maintenance costs. Finally, a low exhaust conversion rate means that the system is not effectively reducing emissions, which can lead to non-compliance with environmental regulations. These issues can have significant consequences for vehicle performance and environmental impact.
Environmental impact
The above sentences describe some common issues related to selective catalytic reduction (SCR) systems used in vehicles to reduce harmful exhaust emissions. The presence of high impurity content can negatively impact the functioning of the SCR system, while a clogged exhaust aftertreatment device can lead to reduced vehicle power. Additionally, the tendency of urea to crystallize can result in the blocking of the SCR nozzle, and a malfunctioning SCR system can increase maintenance costs. Finally, a low exhaust conversion rate can prevent the vehicle from meeting the required emission standards. It is important to address these issues promptly to ensure the safe and efficient operation of vehicles while minimizing their environmental impact.
