An EGR cooler is a device used to reduce emissions from internal combustion engines, which works by reducing the production of nitrogen oxides (NOx) through the process of exhaust gas recirculation (EGR), where the exhaust gases are cooled and then returned to the engine for combustion.
An EGR cooler typically consists of a heat exchanger through which the exhaust gases, once withdrawn from the engine's exhaust pipe, are exchanged with a cooling medium (usually engine cooling water or air) to lower the temperature of the exhaust gases. Lowering the exhaust gas temperature helps to reduce NOx production, which is promoted by high temperature conditions.
By working with the EGR cooler, the engine can reduce NOx emissions to a certain extent, thus complying with environmental emission standards. At the same time, the EGR cooler also helps to improve the combustion efficiency of the engine and reduce fuel consumption.
EGR coolers for commercial vehicles,We supply high-quality components for EGR coolers (inlet and outlet chambers, inlet and outlet water chambers).
Our parts (gas chamber) in the whole EGR cooler plays a role in the connection, the ventilation side is used to connect the exhaust gas through the circular hole for the installation of the EGR valve, the processing of flat surface in the whole connection process to play a sealing role; square port through high-temperature brazing connected to the shell; the material is ZG08Cr18Ni9, the material is corrosion-resistant, high-temperature resistance, which is conducive to improving the service life of the parts
We can supply these parts in different shapes according to the customer's needs.
