The Exhaust Gas Recirculation (EGR) system is sometimes misunderstood as to its function and purpose. In many countries around the world, the emissions of Nitrogen oxide (NOx) from diesel and gasoline vehicles are restricted by legislation. EGR is an effective technical solution to control NOx values. The principle of EGR is to work as a controllable proportion of the exhaust gas is recirculated back into the engine.
EGR
The EGR is used as one of the key components in reducing exhaust gas emissions and pollutants into the atmosphere. Since the introduction of Euro 6 regulations with a reduction of 55% in nitrogen oxides from Euro 5. Between Euro 5 and Euro 6 regulations on diesel engines the drop in Nitrous Oxide (NOx) is from 180mg per driven kilometre to 80mg per driven kilometre
The higher the exhaust gas temperature (over 1800°C), the higher the amount of nitrogen oxides! The EGR is designed to recirculate exhaust gas back in the inlet manifold, by doing so this can lower the exhaust gas temperature by up to 300°C.

Engine Water Pump Construction Car’s water pump is creating forced cooling fluid circulation in the cooling system of the engine . Some water pumps are structurally combine with fans and have a common drive. So the engine water pump installs on the front end of the cylinder block . The water pump housing 3 consists of two parts: one part of the housing is cast from iron and attach to another, which is made together with the cover of the block of distribution gears of aluminum alloy. The water pump shaft 2 and the fan hub 1 rotate on two ball bearings 14 install into the housing 3 . Special snap rings and spacer sleeve keep ball bearings from shifting. There are seals to hold lubricant and to protect against contamination. Engine Water Pump Construction Engine Water Pump Construction 1 – fan and pulley hub; 2 – shaft; 3 – housing; 4 – inspection hole for the release of lubricant from the housing; 5 – lubricator; 6 – water pump impeller; 7 – a control aperture for an ex
