Emission Standards for Turkey

The Challenge: to meet future emission Standards

Now that we more fully understand the impact of pollution on the human body and the whole environment – particularly in cities – and in light of the amazing rates of growth in industrial output and mobility and the associated dramatic increase in energy consumption on the subcontinent the challenge of reducing overall emissions pollution is immense. For the Non-Road Mobile Machinery the Turkish Ministry of Industry is responsible for the emission legislation in Turkey. The Ministry has adopted the emission limit values of the European Non-Road Directives 97/68/EC. Differing were solely the dates of coming into force of stage I-IIIA. The dates of coming into force for stage IIIB and stage IV are identical to those in the European legislation. Turkey also adopted European emission standards for Light-Duty Vehicles which requires Euro 4 with on-board diagnostics since 2007 for diesel engines. Heavy Duty vehicles are required to meet Euro I.

The Solution: technologies intelligently linked

One example for a technical solution for the strict particulate limit for Non-Road Mobile Machinery of 0.025g/kWh, together with the NOx level of 3.3g/kWh for diesel engine in the power range of 56 to 130 kW came into force in April 2012 can be meet today by two technologies.

How the HJS Partial-Flow SMF® works

The hot exhaust gases from the engine – which contain soot particles – pass through the DOC, enter the filter housing and pass through the sintered metal filter (SMF®) developed by HJS. The gaseous components flow in part through the microscopic pores of the filter pockets; the soot particles, including the ultra-fine particles, are trapped on the surface and deposited in the individual filter pockets. The rest of the exhaust-gas flow exits the partial-flow filter through the overflow area.
