Effects of Hot Exhaust Gas Recirculation (EGR) on the Emission and Performance of a Single-Cylinder Diesel Engine

Abstract: With the increment in global demand for energy, there is a need to reduce vehicle emission, which is among the major causes of air pollution around the world. In order to reduce the emissions levels, this study focuses on the effects of hot exhaust gas recirculation (EGR) system on the performance and emissions of a direct injection (DI) diesel engine. The performance studied includes engine power, torque, brake mean effective pressure, fuel consumption and the exhaust emission. The engine used in this study w… Show more

“…99 Although there are different formation mechanisms for nitrogen oxides in the literature, for combustion in CI engines, Zeldovich (thermal) and Fenimore (prompt) mechanisms are accepted as being effectively dominant. 100 In addition, the amount of NO x emissions depends on combustion temperature, oxygen concentration and duration of prevailing high temperatures. It is also reported in the relevant literature that a 100 °C increase in the combustion temperatures increases the amount of NO x emissions 3-fold.…”

“…The modern development of internal combustion engines occurs in the following areas: increasing fuel efficiency; improving environmental safety; increasing power while re-ducing their metal consumption, reducing weight and overall dimensions; creation of hybrid propulsion systems of engines; increasing reliability and resource; improving serviceability; the use of alternative fuels and so on [1,2]. Modern engines are complex technical systems with a large number of units aimed at increasing its efficiency, however, from the technical design of view, they practically do not differ from their classical schemes [3,4]. Preparation of excellent performance and engine performance is carried out by increasing the efficiency of working cycles, the use of progressive design schemes, use of alternative fuels and modern economical electronic fuel injection systems [5].…”

“…Over the past several years, numerous computational and experimental studies have been conducted to reduce the harmful pollutants (e.g., NOx and PM) emitting by diesel engines [3][4][5][6][7]. Recent experimental and numerical investigations show that many researchers still focus on using post-injection of diesel fuel to meet emission regulations in single and dual-fuel engines.…”
