Utilizing One-Way Valve to Optimize Turbocharger Performance on a Blended EGR Engine

Numerical Investigation of the Effect of Cooled EGR on Turbocharger HCCI Engine Performance Fueled with Methane

Performance and Emissions of a Tractor engine operating on biodiesel-diesel blends with EGR

The influences of different diesel/biodiesel blends and EGR rate on brake specific fuel consumption (BSFC), exhaust gas temperature, NO, HC, CO emissions, are studied and demonstrated. In this paper a four stroke direct injection, water cooled, diesel engine was used. Biodiesel either in neat form or as a blend with diesel fuel is extensively investigated to solve the twin problem of reduction ...

Research of Intake Valve Deactivation on Engine Performance

In this paper, the effect of the Intake Valve Deactivation (IVDA) on engine performance is investigated in detail. Based on an optimization platform with Genetic Algorithm (GA) and engine thermodynamic model, the characteristics of the engine volumetric efficiency and pumping loss were studied under the cam-drive, Single Intake Valve (SIV) and Dual Intake Valves (DIV) operating modes, and the e...

Scalable turbocharger performance maps for dynamic state-based engine models

Adapting turbocharger performance maps to a form suitable for dynamic simulations is challenging for the following reasons: (1) the amount of available data is typically limited, (2) data are typically not provided for the entire operating range of the compressor and turbine and (3) the performance data are non-linear. To overcome these challenges, curve fits are typically generated using the p...

A bi-polymer micro one-way valve

We have developed an in-plane bi-polymer check-valve for controlling microfluidic flow and preventing contamination between solutions by tilizing the elastic force of a swollen hydrogel. The valve was created using microfluidic tectonics, a fabrication procedure that allows construction f microscale components and autonomous systems using liquid-phase photopolymerization and in situ fabrication...
