Effects of EGR rate on performance and emissions of a diesel power generator fueled by B7

Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2017
This paper analyses the impacts of the application of an exhaust gas recirculation (EGR) system on the performance and emissions of a stationary, direct-injection diesel engine operating with diesel oil containing 7% biodiesel (B7).

Numerical Investigation of the Applicability of Low-Pressure Exhaust Gas Recirculation Combined with Variable Compression Ratio in a Marine Two-Stroke Dual-Fuel Engine and Performance Optimization Based on RSM-PSO

Journal of Marine Science and Engineering
In this paper, a novel technical route, namely combining the low-pressure exhaust gas recirculation (LP-EGR) and variable compression ratio (VCR), is proposed to address the inferior fuel economy for marine dual-fuel engines of low-pressure gas injection

Egr-2 prevents self-reactions

The Journal of Experimental Medicine, 2008
![Graphic][1] Overproliferating T cells infiltrate the liver and trigger lupus-like autoimmunity in older Egr-2–deficient mice. Self-tolerance is well known to be enforced in part by an external force of regulatory T cells. Now, Zhu et al.

Cyclic heat release variability in a spark ignition engine under exhaust gas recirculation

MATEC Web of Conferences, 2019
We have studied cyclic heat release variability in a spark-ignition engine under exhaust gas recirculation (EGR), using nitrogen to simulate EGR. Five EGR levels are examined. We used wavelet analysis to identify the dominant modes of fluctuation and how

Development of a spark discharge model for predicting ignition stability in high EGR conditions in SI engines

Nihon Kikai Gakkai ronbunshu
Recently, EGR (Exhaust Gas Recirculation) combustion has been used to enhance the thermal efficiency of internal combustion engines. However, EGR combustion causes ignition instability, leading to increased cycle-to-cycle combustion variability and ...
