In this experimental study, the fuel system of the OM364 diesel engine manufactured by IDEM company, which operates in the basic mode with inline fuel pump and mechanical governor control, is upgraded to a common rail system with electronic control by the ECU. Also, emmssion of exhaust gases is reduced by SCR and DOC catalysts then performance and emmission parameters of engine are compared i...

as motorcycles are named as one of the important air pollution emission sources in tehran, investigating their emission performance and finding a solution for reducing their emission is of high importance. in this study, emission factors from 60 motorcycles from tehran’s present fleet and 4 closed loop injection fuel supply system and catalytic converter equipped motorcycles were measured. meas...

To determine the amount of air pollutants, produced by Iranian automakers, and compare it with old and retrofitted vehicles have become one of the important tools of urban management. The present research uses International Vehicle Emission (IVE) modeling software in order to verify SAIPA Co. fleet emissions, based on Euro 4 emission standard (SAIPA Co. recognized as a superior Iranian brand in...

Commonly, the NOx emissions rates of diesel vehicles have been assumed to remain stable over the vehicle's lifetime. However, there have been hardly any representative long-term emission measurements. Here we present real-driving emissions of diesel cars and light commercial vehicles sampled on-road over 15 years in Zurich/Switzerland. Results suggest deterioration of NOx unit emissions for Eur...

The quick growth of vehicles is due to fast urbanization in mega cities during last decades. This phenomenon has serious impacts on air quality, as emission from mobile vehicles is the major source of air pollution. As a result, any attempt to reduce the emitted air pollutants is needed. This study aims at improving the fuel quality in transporting system with particular emphasis on taxis in Te...

Forty light-duty gasoline vehicles (LDGVs), ninety two diesel trucks (DTs), and twenty rural vehicles (RVs) were measured in Beijing, Xi’an, and Shenzhen in China using a portable emissions measurement system (PEMS). We obtained gaseous emission factors (EFs) for LDGVs of different emission control technologies (including Euro 0, Euro I, Euro II, Euro III and Euro IV), and EFs of fine particula...

OBJECTIVE The purposes of this study were to determine the following: 1) the exposure levels of municipal household waste (MHW) workers to diesel particulate matter (DPM) using elemental carbon (EC), organic carbon (OC), total carbon (TC), black carbon (BC), and fine particulate matter (PM 2.5) as indicators; 2) the correlations among the indicators; 3) the optimal indicator for DPM; and 4) fac...

The European Commission recently presented its proposal for Euro VI emission standards for vehicles with heavy duty diesel engines (trucks and buses). The proposal calls for reductions in 2013 in the emissions of particulate matter (-67%) and NO x (-80%) compared to the Euro V requirements. In the Netherlands, the implementation of this proposal will lead to a reduction of the total NO x emissi...
