The knock study of high compression ratio SI engine fueled with methanol in combination with different EGR rates

, 2019
Methanol, with a high octane index, is considered to be one of the most ideal fuels for high compression ratio engines. In this paper, the SAGE models combined with methanol chemical reaction kinetics (consisting of 46-species and 247-elementary ...

Comparing Lean Burn and EGR

SAE Technical Paper Series, 1997
<div class="htmlview paragraph">Lean burn and EGR are two commonly used technologies for improving fuel consumption and controlling emissions. Each has advantages and disadvantages when applied to an engine and, qualitatively at least, these effects are well known. To meet future emissions and fuel consumption constraints, most production engines

Effect of EGR routing on efficiency and emissions of a PPC engine

Applied Thermal Engineering, 2019
In order to significantly improve engine efficiency and reduce exhaust emissions at the same time, new radical combustion concepts have emerged. Gasoline partially premixed combustion (PPC) is one of them, with early results showing high gross indicated ...

Investigating the EGR rate and temperature impact on diesel engine combustion and emissions under various injection timings and loads by comprehensive two-zone modeling

Energy, 2018
The impact of exhaust gas recirculation (EGR) on combustion and emissions in direct injection (DI) diesel engine is examined in a predominately computational study, where the influence of EGR rate and temperature at various injection timings and loads is

Resolving EGR Distribution and Mixing

SAE Technical Paper Series, 2002
<div class="htmlview paragraph">A minimally invasive spatially resolved capillary inlet mass spectrometer has been used to quantify EGR/air mixing in a Cummins V-8 medium-duty diesel engine. Two EGR-system hardware designs were evaluated in terms of EGR-air mixing at the intake manifold inlet and port-to-port EGR charge uniformity.

Effect of EGR dilution on combustion, performance and emission characteristics of a diesel engine fueled with n-pentanol and 2-ethylhexyl nitrate additive

Energy Conversion and Management, 2018
The n -pentanol/diesel dual-fuel coupled with EGR (exhaust gas recirculation) technology could simultaneously reduce soot and nitrogen oxide (NO X ) emissions discharged from the compression ignition engine.

The potential of dimethyl carbonate (DMC) as an alternative fuel for compression ignition engines with different EGR rates

, 2019
Dimethyl carbonate (DMC) has high oxygen content (53.3%) and a non-toxic preparation, which is a promising additive for diesel fuel. Exhaust gas recirculation (EGR) technology inhibits the formation of NOX.

Alternative Fuel Testing on a Port Fuel Injected LPL EGR and D-EGR® Engine

SAE Technical Paper Series, 2016
<div class="section abstract"><div class="htmlview paragraph">A turbocharged 2.0 L PFI engine was modified to operate in a low-pressure loop and Dedicated EGR (D-EGR^®) engine configuration. Both engine architectures were operated with a low and high octane gasoline as well as three ethanol blends.
