Exhaust Gas Recirculation (EGR) systems were one of the first emissions systems introduced on modern diesel engines. (xtremediesel.com)
Get the emissions sensors you need to ensure your engine and emissions systems maintain proper operation. (xtremediesel.com)
These devices are integrated into combustion chambers, intake manifolds, and ignition systems which controls exhaust emissions and improves the fuel economy of the vehicle. (marketresearchfuture.com)
Furthermore, it also gives insight on diesel aftertreatment systems design and strategies aiming to enhance low temperature catalysts activity. (birmingham.ac.uk)
The European Commission (EC) is calling on nations to implement new technologies and smart pricing systems to encourage an uptake in low-emission transport modes. (edie.net)
However, as long as a large portion of the vehicle fleet does not have any PM removal systems, the usage of HVO and RME will have a positive impact on overall PM reductions. (lu.se)
For combustion vehicles, the most efficient way to reduce EC emissions is by using aftertreatment systems focused on removing the PM, such as DPFs. (lu.se)
Resources need to be focused on ensuring that such systems are in place and working effectively in all combustion vehicles. (lu.se)

The fuel economy and emission characteristics of this test PHEV were estimated using the extended-HILS, which is combined the real engine with the PHEV model of the HILS (Hardware-In-the-Loop-Simulator). (sae.org)
NOx and CO 2 emission of this test PHEV which was equipped with an EHC was good, compared with the heavy-duty diesel engine vehicle, the heavy-duty diesel hybrid electric vehicle and the PHEV which was not equipped with an EHC. (sae.org)
The potential of internal EGR (iEGR) and external EGR (eEGR) in reducing the engine-out NOx emissions in a heavy-duty diesel engine has been investigated by means of a refined 1D fluid-dynamic engine model developed in the GT-Power environment. (sae.org)
The test vehicle, an AMC Hornet having a 232 CID six cylinder engine, was tested over the Federal Test Procedure, the Highway Fuel Economy Test, and the Sulfate Emission Test. (epa.gov)
However, low exhaust temperature of the diesel engine leads to the activity of the SCR catalyst being reduced, and it was thus not capable of decomposing PAHs effectively. (aaqr.org)
It must be capable of delivering full power reliably run-after-run on race day, at engine and vehicle speeds far in excess of those encountered in normal driving. (j-body.org)
The engine is also upgraded with larger turbochargers, an optimized intercooling system and a stainless-steel exhaust system with high-flow catalysts. (motorauthority.com)
At -5 °C, however, the combustion engine is used intermittently from the start of the test to warm up the catalyst. (theicct.org)
Unexpectedly, the combustion engine was also used to charge the battery when sports vehicle- and transmission-mode was selected, even when charge-increasing mode was not engaged. (theicct.org)
Lean-burn NOx traps (LNT) use a catalyst to capture NOx during lean engine (low-fuel) operation. (torquenews.com)
The Bureau of Mines studied the characteristics of simulated coal gas as an automotive fuel in two multicylinder vehicles in a standard and high-compression-ratio engine configuration. (cdc.gov)
Diesel particulate filters have been shown to be highly efficient in filtering DPM, removing up to 99% of DPM from diesel engine emissions. (cdc.gov)
Figure 1 shows a schematic of the basic concept of filtering where engine emissions (blue arrows) enter at one end of the filter and then must physically flow through the filter wall, which removes the DPM, before exiting the filter. (cdc.gov)

LTO explosion aerosols showed characteristics of both types of emissions. (cdc.gov)

This study assesses, via testing of a representative PHEV, the effect of ambient temperature and use of air-conditioning on CO 2 emissions, electric energy consumption, and electric ranges. (theicct.org)
