Internal exhaust gas recirculation (EGR) is an effective strategy to reduce pumping loss and improve fuel economy using mixture dilution than traditional external EGR. In this paper, the internal EGR was obtained by exhaust gas trap (EGT) using the negative valve overlap (NVO) method. The...

Fuel stratification has the potential to extend the high load limits of homogeneous charge compression ignition (HCCI) combustion by improving the control over the combustion phase as well as reducing the maximum rate of pressure rise. In this work, experiments were carried out on a...

Impurities such as N2 and O2 can be co-injected with CO2 to cut the overall cost of carbon capture and geological storage by lowering the CO2 capture cost. However, only few field-scale studies have focused on the effect of these impurities, such as N2 and O2, with low solubility and a low...

This study was focused on preparation and characterization of fatty acid eutectic mixtures as phase change materials (PCMs). The four common fatty acids: stearic acid (SA), palmitic acid (PA), myristic acid (MA) and lauric acid (LA) were selected as representative to prepare binary and ternary...

Solid sensible heat storage is an attractive option for high-temperature storage applications in terms of investment and maintenance costs. Typical solid thermal energy storage systems use a heat transfer fluid to exchange heat as the fluid flows through a tubular heat exchanger embedded in the...
