Common Rail Systems of Euro 5 VS Euro 6 standard

Posted on 2/26/2016 11:37:04 AM

By using a lots of technical innovations,Euro 6 requires nitrogen oxide (NOx) emissions must be reduced by a further 77%, while soot particle emissions must be cut by 66%.In other word,nitrogen oxide emissions have to be reduced from 2.0 to 0.46 grams/kWh, and soot particle emissions from 0.03 to as little as 0.01 grams/kWh. Compared with the current Euro 5 standard,these are however not the only requirements: Euro 6 engines must meet these stringent requirements for a minimum of seven years or 700,000 km, in all operating conditions.

Meanwhile the common rail injection pressure could reach up to 2,500 bar which will allow the opportunity to use pre- and post-injection, or a combination of both.It will lead to finer atomisation and many more possibilities to optimise combustion, ensuring the lowest possible emission and noise levels, and the lowest possible fuel consumption.In the achieving maximum efficiency and low emissions,the components in the engine like new sensors and actuators plays very important role.
Now DAF has already introduced the Euro 6 engine with common rail - the 12.9 litre Euro 6 PACCAR MX-13 engine.In reliability and durability,they have step forward.
