Will diesel survive Euro 6?
Trucks have always been equipped with a diesel engine. The high emission of particulate matter, nitrogen oxide (NOx) and carbon dioxide (CO2) makes a diesel engine a controversial issue. The strict Euro 6 standard requirements are supposed to force manufacturers to market cleaner diesel engines. EGR (Exhaust Gas Recirculation) and SCR (Selective Catalytic Reduction) technology would achieve this. The SCR catalyst is a technical device in the exhaust of a vehicle with a diesel engine that converts the nitrogen oxide in exhaust gas by adding AdBlue (an aqueous urea solution). EGR technology has been applied by manufacturers for some time to reduce nitrogen oxide (NOx) emissions. However, many of the trucks equipped with EGR technology, which their manufacturers claim meets the Euro 6 standard requirement, are still not clean enough. This has been proven through practical tests. This is why the European Commission decided to introduce a new Real Driving Emission (RDE) test on 19 May 2015. The new Real Driving Emission test is expected to be applied as of 2017. This will be the moment of truth for diesel engines.
Clean fuel for heavy-duty trucks: LNG
LNG combustion is much cleaner than diesel combustion: nearly no particulate matter, 25% lower NOx emissions and 10% lower CO2 emissions. Driving on LNG already meets the Euro 6 standard emission requirements without costly post-treatment to prevent soot and particulate emissions. An LNG engine is also 50% quieter than a diesel engine, allowing Peak certification for loading and unloading outside the usual time windows.
