Performance Evaluation and Emissions improving of Turbocharged DI Diesel Engine with Exhaust Gas Recirculation (EGR)
Nitrogen oxides (NOx) contribute to a wide range of environmental effects including the formation of acid rain and destroy ozone layer. In-cylinder high temperature flame and high oxygen concentration are the parameters which affect the NOx emissions. The EGR system is a very effective way for reducing NOx emission from a diesel engine (via reduction of these parameters), particularly at the...
متن کاملRotating injector in DI diesel engine for improving performance and reducing NOx emission
Oxides of Nitrogen are the major emission from a diesel engine. It is due to heterogeneous diffusion combustion system with fuel-rich regions, which produce high local temperature around the periphery of the spray where high formation rate of NO is promoted. Various techniques are therefore employed to reduce the NOX emission like EGR, SCR, etc. In this present work a rotating injector is a tec...
متن کاملThree-Dimensional Modeling of Combustion Process, Soot and NOx formation In a Direct-injection Diesel Engine
This paper is presented to study the combustion process and emissions in a direct injection diesel engine. Computations are carried out using a three-dimensional model for flows, sprays, combustion and emissions in Diesel engines. Interactions between combustion and emissions with flow field are considered and it is shown that soot mass fraction increases at regions with low turbulence inten...
متن کاملNOx Emission Prediction Based on Measurement of in-Cylinder Pressure for CI Engine Running with Diesel and Biodiesel
NOx is one of the major toxic emissions that needs to be regulated stringently in both EU and USA emission regulations. The engine designer is keen to get an accurate, reliable and cost effective NOx measurement system. In this paper, the application of the cylinder pressure for predicting the NOx emission of compression ignition (CI) engine fuelled with diesel and biodiesel during steady state...
متن کاملEffect of Direct Injection Diesel Engine Convert to Sequential Injection CNG Engine in Intake Port Gas Flow Pressure Profile
The one dimension computational model of a sequential injection engine, which runs on compressed natural gas (CNG) with spark ignition, is developed for this study, to simulate the performance of gas flow pressure profile, under various speed conditions. The computational model is used to simulate and study of the steady state and transient processes of the intake manifold. The sequential injec...
