What is the TIER / STAGE emission standard The TIER / STAGE standard applies to the emission level of diesel engines. TIER is a standard that originated in North America. Its European counterpart is the STAGE emission standard. Both standards apply to the exhaust emissions of specialized vehicles such as agricultural machinery (tractors, harvesters), construction …
What is the SCR (DEF / AdBlue) system? SCR is a Selective Catalytic Reduction system, the purpose of which is to minimize emissions of particulate matter (PM) and nitrogen oxides (NOx) in diesel engines. The entire process takes place in a catalytic converter installed in the exhaust system. Nitrogen oxides are converted to nitrogen and …
What is the EURO6 standard exhaust emission The EURO6 standard is the European standard for exhaust emissions, or the permissible emissions generated by vehicles sold in Europe. EURO 6 is a directive that applies to trucks manufactured since 2014. It specifies the following requirements for exhaust emissions: emisja [g/km] EURO 5 CO 0,5 HC 0,05 …
What is the EURO5 exhaust emission standard EURO5 standard – this is the standard for the permissible emission of exhaust gases generated by vehicles sold in Europe. EURO5 is a directive applicable to trucks produced from 2007 to 2014. It specifies the following emission requirements: emisja [g/km] EURO 5 CO 0,5 HC 0,05 NOx 0,18 …
ECU in diesel engines ECU – Engine Control Unit (sometimes referred to as ECM – Engine Control Module) is an electronic device designed to manage the operation of an internal combustion engine. Based on the many sensors that the controller works with, it selects the ratio of the fuel and air mixture. It also monitors …
What is a DPF? DPF – a diesel particulate filter (FAP from french Filtre À Particules) is a filter located in the exhaust system of diesel (diesel) vehicles. The filter is installed in engines meeting the EURO 4 standard and above. Its purpose is to clean the exhaust from particulate matter (ash and soot). The …
What is a DPF (FAP) emulator? A DPF emulator is a device that simulates the operation of a fully operational diesel particulate filter (FAP/DPF). As a result, the engine ECU does not force regeneration of the filter and does not report errors caused by the lack of filter patency. The FAP emulator is an effective …
AdBlue – what is it and what is it used for? AdBlue is the trade name for a high-purity diesel exhaust fluid – a 32.5% aqueous urea solution. It is a registered trademark owned by the Verband der Automobilindustrie. The fluid is used by the SCR system in the catalytic converter to clean the exhaust …
What is an SCR emulator? The SCR emulator is a device that simulates the operation of a fully operational DEF/SCR system (AdBlue / urea dosing). Therefore, the engine ECU does not limit power or torque and does not report errors caused by exceeding exhaust emissions. The DEF emulator “replaces” all sensors related to the SCR …
