Consumption of fuel oil is increasing, but it is not accompanied by supply. Transportation sector is spent the most existing fuel. Therefore, it is crucial to look for alternative type of fuel such as biodiesel to overcome the fuel shortage. The purpose of this study is to investigate the feasibility on how the investment of waste cooking oil as the biodiesel material production. This study con...

Fuel droplets in combustors interact strongly with flames and turbulence in practical liquid-fueled combustors of terrestrial and aerial propulsion systems (Williams 1965; Sirignano 1999). Although a great deal of physical understanding has been achieved in purely gaseous combustion over the last century, not much is currently known about spray combustion at the fundamental level. In this short...

This paper proposes a design of power system control in the hybrid electric vehicle. It adopts the isolated DC/DC power converter as the front-end fuel cell and Lithium-ion battery to supply constant voltage. By micro-controller to detect the hybrid power output, and the low-pressure hydrogen storage temperature, and the adjustment of the power output ratio to provide the energy for loading bal...

The effect of fuel properties on the structure of swirling spray flames has been investigated. Droplet size, number density and velocity measurements have been carried out in pressureatomized spray flames using phase/Doppler interferometry. Four fuels with different physical properties were studied, namely n-heptane, methanol, 50/50 methanol/1-dodecanol mixture, and kerosene. The results indica...

LLE Review, Volume 113 16 Introduction In the inertial confinement fusion (ICF) approach to fusion, a spherical shell filled with a deuterium–tritium (DT) mixture is compressed to reach a temperature of 10 to 12 keV in the lower-density central core region (hot spot) to initiate a burn wave through the higher-density colder main fuel surrounding the core.1–3 The main fuel areal density (tR) at ...

We have developed a novel electrolytic cell pressurized by D2 in which deuterium loading ratio in a palladium cathode can be determined in-situ during the calorimetric measurements of excess heat. A gas diffusion type fuel cell anode is partially immersed in the electrolyte solution to act as a counter electrode, at which electrochemical oxidation of deuterium gas molecules to deuterium ions ta...

A minor actinides (MAs)-burning core system is proposed for future LMFBRs. It provides high-bumup, a long cycle length and enhanced safety characteristics. MAs are transmuted in two steps. MAs are mixed into the blanket fuel only. Pu, reprocessed from discharged blanket fuel, is mixed into the core fuel of an axially heterogeneous core (AHC). Advantages of this MAbuming system include reduction...

Abstract– This paper proposes an intelligent control technique for fuel injection control of Compressed Natural Gas (CNG) engines. Recurrent Neuro-Fuzzy Networks are used to estimate and control air to fuel ratio (AFR) of CNG engines. To reasonably handle such a complicated control problem, a precise experimental test has been done on a real CNG fuelled vehicle and the process input output data...

A three-step development, optimization and validation strategy is described for gas chromatography (GC) fingerprints of Brazilian commercial diesel fuel. A suitable GC-flame ionization detection (FID) system was selected to assay a complex matrix such as diesel. The next step was to improve acceptable chromatographic resolution with reduced analysis time, which is recommended for routine applic...

Chris Manzie, Harry Watson, Marimuthu Palaniswami Department of Electrical and Electronic Engineering Department of Manufacturing and Mechanical Engineering The University of Melbourne, Victoria, Australia, 3010 Abstract: Despite being one of the fastest growing alternative fuel sources, little attention has been given to control of the air fuel ratio at the point of combustion in liquefied pet...
