Exhaust back pressure refers to the resistance pressure of engine exhaust. When exhaust back pressure increases, the engine exhaust flow is obstructed, thus affecting engine power. Exhaust back pressure has a significant impact on overall engine performance. Generally, increased exhaust back pressure directly leads to higher fuel consumption, worsening engine economy, and simultaneously reduced engine power. Furthermore, incomplete combustion in the cylinders exacerbates the deterioration of exhaust emissions.
An exhaust back pressure tester is a device used to test the back pressure of an exhaust system. It is commonly used in industrial fields, particularly in the production and repair of engines and exhaust systems. Although it differs from temperature testers in brand and specifications, back pressure testers also prioritize measurement accuracy and resolution. Back pressure testers help technicians accurately assess and adjust the operating condition of the exhaust system.
