This paper focuses on the effects of internal and cooled external exhaust gas recirculation (EGR) on the combustion and emission performance of diesel fuel homogeneous charge compression ignition (HCCI). The use of fuel injection before the top center (TC) of an exhaust stroke and the negative...

Through experiments conducted on a single cylinder direct injection (DI) diesel engine, effects of exhaust gas recirculatoin (EGR) on combustion and emission during cold start were investigated. Combustion of first firing cycle can be promoted significantly by introducing EGR. In experiments,...

The exhaust gases contain large amounts of unburned hydrocarbons during cranking without combustion. The effects of unburned hydrocarbon recirculation on ignition and combustion during diesel engine cold starts were investigated using both experiments and simulations. Experiments were conducted...

The basic chemical composition of coal and ash is an important but insufficient characteristic for the reliable explanation of coal properties. The modes of occurrence of the elements, their origin and concentration in coal, as well as their behavior during the coalification process, are also...

Phase change material (PCM), has been widely researched in many previous works, shows a good potential for thermal energy storage. The present paper investigated the mesoscopic morphologies and evolution mechanism of microencapsulated phase change materials (MEPCMs) using dissipative particle...

Oxygen-enriched combustion of diesel engine can reduce smoke emission and improve thermal efficiency, but also lead to the increase of NO emission. In this research, experiments were conducted on a turbo-charged direct injection diesel engine under the two conditions of 2000 rpm and 180 Nm...

The traditional ORC (organic Rankine cycle) based geoplant results in a higher irreversible loss. The PDORC (parallel double-evaporator organic Rankine cycle) was put forward to decrease the system irreversibility and enhance the power output. The TEIC (thermal efficiency intensification...
