Will Urea Affect Engine Power?

Urea will affect engine power. Hazards of not using urea: Not using urea may lead to decreased engine power. For China IV standard vehicles, there is a DCU chip between the urea tank and the engine, which determines the required amount of urea solution injection based on engine power. Forced deactivation will cause the SCR system to remain in a high-temperature state for extended periods, leading to damage. The SCR system is costly, with most components being imported, making replacement expensive. Introduction to automotive urea: It is a liquid used in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. Its composition consists of 32.5% high-purity urea and 67.5% deionized water.
