The results show: The brake specific emissions of CO, HC and PM all meet their limits, which are 56.7%, 84.8% and 89.0% of their limits respectively; The brake specific emissions of NOx exceeds 44.6% of its limit.
We are of the opinion that when EMDI and UF are mixed first, without adding NH4Cl and then sprayed onto particles, mechanical properties will be improved and F-emissions will meet E1 grade requirements.
Combustion and emissions of the diesel engine using bio-diesel fuel
The emissions, such as CO, HC, and particulate matter decrease remarkably whereas NOx increases a little.
Preliminary study of trace element emissions and control during coal combustion
Hazardous trace element emissions have caused serious harm to human health in China.
The source apportionment analysis suggests that PAHs from PM2.5 in Beijing city mainly come from coal combustion and vehicle exhaust emission.
Influence of air intake pipe on engine exhaust emission
This paper describes the development of artificial neural network-based vehicular exhaust emission models for predicting 8-h average carbon monoxide concentrations at two air quality control regions (AQCRs) in the city of Delhi, India, viz.
A coefficient-based vehicular exhaust emission model is being developed jointly with the variable-grid urban airshed model (UAM-V) of Systems Applications International (SAI), and integrated within a GIS (ArcInfo) framework.
The spatial patterns of metal distribution in the sediment could be due to the different pollution sources such as exhaust emission from boats and other environmental variables such as clay content of sediment or tide level.
It is a novel approach for full utilization of heat energy during heat treatment, which increased 30 % of the heat efficiency when compared with normal air-cooler methods that directly put exhaust air into atmosphere.
Properties of La1-xCexCoO3 system perovskite-type catalysts for diesel engine exhaust removal
The catalytic activity of the catalysts in removal of NOx, total hydrocarbon (THC) and particulate matter (PM) from diesel exhaust gases were examined in detail using temperature-programmed reaction technique.
Pre-spray (PS) strategy, which means supplying highly pressurized air into the exhaust manifold two seconds before the accelerating-graph begins to rise and stopping spraying air when the accelerating-graph stops rising.
Selective catalytic reduction of NOx from exhaust of lean-burn engine over Ag-Al2O3/cordierite catalyst
