DESCRIPTION
The Doser Pump (part number 4377364RX) is a component found in modern diesel engines. It is responsible for injecting precise amounts of Diesel Exhaust Fluid (DEF) into the exhaust stream to reduce harmful emissions. The pump operates by drawing DEF from the vehicle's tank and pressurizing it before delivering it to the exhaust system through a dosing valve. This process allows for accurate and efficient injection of DEF, helping the engine meet emissions standards while improving fuel economy. The Doser Pump plays a critical role in reducing harmful pollutants emitted from diesel engines, making it an important component for compliance with environmental regulations.
