Reduction of pollutants emissions on SI engines: accomplishments with efficiency increase

Effect of Intake Primary Runner Blockages on Combustion Characteristics and Emissions with Stoichiometric and EGR-Diluted Mixtures in SI Engines

A New Strategy for Reduction of Emissions and Enhancement of Performance Characteristics of Dual Fuel Engines at Part Loads

Increasingly restrictive emission regulations and renewed focus on energy efficiency drive the current researches to find alternative fuels and their related better combustion strategies. In this regard, dual fuel engines, in which natural gas fuel is used as a main fuel and diesel fuel is employed as a pilot fuel, have received considerable attention. However, poor fuel utilization efficiencie...

Nanoparticle Emissions from Engines

Recently concerns about possible increases in emissions of ultrafine and nanoparticles and their environmental impact have been voiced. A major problem with assessing the significance of such emissions is that, unlike the carbonaceous soot particles associated with older Diesel engines, many of these particles are not formed in the engine but instead by gas-to-particle conversion processes from...

the effect of consciousness raising (c-r) on the reduction of translational errors: a case study

در دوره های آموزش ترجمه استادان بیشتر سعی دارند دانشجویان را با انواع متون آشنا سازند، درحالی که کمتر به خطاهای مکرر آنان در متن ترجمه شده می پردازند. اهمیت تحقیق حاضر مبنی بر ارتکاب مکرر خطاهای ترجمانی حتی بعد از گذراندن دوره های تخصصی ترجمه از سوی دانشجویان است. هدف از آن تاکید بر خطاهای رایج میان دانشجویان مترجمی و کاهش این خطاها با افزایش آگاهی و هوشیاری دانشجویان از بروز آنها است.از آنجا ک...
