New Innovations are being Developed in Diesel Engines and Drive Technologies

The diesel engine sector has been one of the most active and innovative areas for technological development in the past 10 years. Engine firms have invested enormous sums in developing new, low emissions technologies that reduce the quantities of nitrous oxide and particulates from the tailpipe. All the firms have taken a different approach in this regard, using various combinations of the technologies available such as diesel particulate filters (DPF), selective catalytic reduction (SCR), exhaust gas regeneration (EGR) and high-pressure, common rail fuel systems.

These technologies have all required major changes to the machines as the engines run hotter and require more cooling, as well as having to be quieter. The often bulky after-treatment systems all take up more room also, resulting in equipment manufacturers having to carry out careful redesigns of their machines to ensure that visibility for the operator can be maintained, while also allowing service access for these new components.

January 2014 will be a major milestone for this technological development as this is when machines sold into North America, the European Union and Japan will have to begin to comply with the toughest set of emissions legislation yet,

Tier 4 Final/Stage IV. The legislation is introduced in phases with different engine power output categories having to meet these tough targets at different times. But engine firms are already unveiling the low emissions solutions they will be offering for use in Europe, Japan and the US from January 2014.

These latest low emissions engines require clean fuel supplies and can only be used in markets where low sulphur fuel is available however. And this has resulted in manufacturers developing new machines for emerging markets where the low emissions technology is not required and featuring the earlier and well-proven Tier 2/Stage II or Tier 3/Stage III technology.

From Yuchai engine, most range of Yuchai engine meeting the Tier 4 Final/Stage IV emission standard,They not only is famous engine brand in China,but also they are popular brand in Europe by they best emission technology.
