Experimental analysis of a spark-ignition engine using exhaust gas recycle at WOT operation

Effect of Exhaust Gas Recirculation (EGR) on Performance and Emission of a Compression Ignition Engine with Staged Combustion (Insertion of Unburned Hydrocarbon)

“…Kusaka et al also found that at low loads, EGR co mbined with intake heating can favorably reduce THC emission with imp rovement in thermal efficiency [16]. EGR was also used in a direct injection spark ignition engine as an effect ive way for improving fuel economy [17,18]. Das et al used EGR to reduce NOx emissions in hydrogen -supplemented SI engine without any undesirable co mbustion phenomena [19].…”

Performance and NOx Investigation on Diesel Engine using Cold EGR Spiral Tube: A Review

“…2017. 213-220 (pISSN: 2541-5972, eISSN:2548-1479) 218 economy [20,21] [22]. Sato et al performed experiments using methanol in direct injectioncompression ignition engine and found that combustion performance becomes inferior under light load conditions becausetemperature in combustion chamber fell due to very high latentheat of methanol, thus hampering formation of combustibleair-fuel mixture [23].…”

Influence of cooled exhaust gas recirculation on performance, emissions and combustion characteristics of LPG fuelled lean burn SI engine

“…Hence, this limits the EGR percentage on account of NOx emission formation. Keeping into account of the previous literatures, an SI engine fueled with LPG which is suitable for lean operation was chosen and the effect of EGR on its operation was experimentally tested at wide open throttle conditions [21,23,24]. The EGR flow rate was interpreted as the percentage of EGR in the total charge (air + fuel+ exhaust) on the volume basis.…”
