Increases in energy demand and waste are a major cause of natural resource depletion environmental pollution, technology capable processing to convert it into is required mitigate this issue. Hydrothermal carbonization (HTC) an example that can energy, various studies have been conducted using for fuel conversion. This study focused on the production solid equivalent coal power generation throu...

The objective of this research was to develop advanced diesel combustion strategies for emissions reduction in a multi-cylinder diesel engine. The engine was equipped with an electronically-controlled, common-rail fuel injection system, and an exhaust gas recirculation (EGR) system. This experimental setup allowed a wide range of operating conditions to be explored. Effects of various injector ...

Vegetable oil causes problem when used as fuel in compression ignition engines. This problem is due to high viscosity and low volatility of vegetable oils, which can be minimized by the process of transesterification. The relatively high cost of refined vegetable oils render the resulting fuels unable to compete with petroleum derived fuel. To reduce the cost of biodiesel a relatively low cost ...

Consider the route you took when you drove to work today. Are you going to take a significantly different route tomorrow? How comfortable would you be flying on a plane for which all pre-flight safety evaluations were based solely on the pilot’s intuition or experience? Perhaps the pilot doesn’t feel that the fuel level needs to be checked. Or the landing gear. Or the engines. Would you board t...

In the present work, the influence of a very early pilot injection on pollutant formation was investigated in a Common-Rail DI Diesel engine. The engine was operated at conventional part-load conditions at 2000 rpm, an EGR variation was done and the injected fuel mass was 15 mm^3/cycle. The Nozzle type were conical and flow optimized geometries (ks nozzle) with hole diameters of 0.141 mm, lengt...

Many extreme scale scientific applications have workloads comprised of a large number of individual high-performance tasks. The Pilot abstraction decouples workload specification, resource management, and task execution via job placeholders and late-binding. As such, suitable implementations of the Pilot abstraction can support the collective execution of large number of tasks on supercomputers...
