In order to continue to meet and exceed the current emission standards for diesel engines for large companies to improve the top five, including internal combustion, fuel quality, oxidation catalytic converter, nitrogen oxides (NOx) emissions control device (or post-processing) and diesel particulate trap - (DPF).

The focus should be on optimizing the internal combustion engine design, using various ways to reduce emissions in order to achieve satisfactory results. As more and more strict emissions regulations, and must therefore focus on how to control INOx and particulate (PM). In order to reduce the emissions V1OTDI engine, engine fitted with a pneumatic control exhaust gas recirculation (EGR) valve and EGR radiator. Oxidation catalytic converters installed in close to the location from the engine, the greatest extent possible not to clean up the emissions control. Two-slip road exhaust system has two catalytic converters: a pre-ceramic oval converters, installed in close to the location from the engine, another three oval into the engine to fit in at the bottom.
