Effect of fuel injection strategies and EGR on biodiesel blend in a CRDI engine

Energy, 2019
Biodiesel appears as a replenishable and sustainable energy source and can be used a direct replacement to petro-diesel without any major transformations in ongoing diesel engines. This work concentrates on production of Calophyllum Inophyllum biodiesel (

Reciprocal modulation between Sp1 and Egr‐1

Journal of Cellular Biochemistry, 1997
Many ubiquitously expressed genes, including oncogenes, lack a proximal TATA or CAAT box but have a region of G + C-rich sequences that appears to replace the usual promoter initiation site. The zinc-finger protein Sp1 is one of the prevalent activators of these genes.

EGR control and simulation about EGR rates influence on diesel engine operation performance

2011 International Conference on Electric Information and Control Engineering, 2011
According to the basic structure of actual diesel engine, a control project and simulation model of TDI diesel engine with EGR system was established. Based on the optimum EGR rates map of diesel engine test experiment as control map of EGR control unit, the simulation on EGR control unit was constructed.

Potentials of EGR and lean mixture for improving fuel consumption and reducing the emissions of high-proportion butanol-gasoline engines at light load

, 2020
Biobutanol is a promising alternative fuel, but it is accompanied by a fuel consumption penalty. To mitigate the fuel penalty, air dilution was investigated in a turbocharged gasoline direct injection engine fueled with isobutanol-gasoline (B73).

Vacuum EGR Valve Actuator Model

SAE Technical Paper Series, 1998
<div class="htmlview paragraph">As part of a general <b>EGR</b> system model, an adiabatic thermodynamic vacuum <b>EGR</b> valve actuator model was developed and validated. The long term goal of the work is improved system operation by correctly specifying and allocating <b>EGR</b> system component requirements.
