This paper investigates the performance characteristics of rapeseed methyl ester, EN 14214 biodiesel, when used for electrical generation in compression ignition engines. The work was inspired by the need to replace fossil diesel fuel with a sustainable low carbon alternative while maintaining generator performance, power quality and compliance with ISO 8528-5. A 50 kVA Perkins diesel engine generator...
In order to improve aircraft efficiency, reliability and maintainability, the aerospace world has found in the progressive electrification of on-board services the way to reduce or to remove the presence of the hydraulic, mechanical and the bleed air/pneumatic systems. This concept is called more electric aircraft (MEA), which involves the introduction of the electromechanical actuators (EMAs) and...
This paper describes the gear-shift schedules for the Automated Mechanical Transmission(AMT) utilized in the parallel hybrid vehicle, which is equipped with an Integrated Starter Generator (ISG). The effects of the battery's state of charge (SOC) and ISG's performance on the gear shift schedules have been investigated. Both the power gear-shift, schedule in which the ISG provides the peak torque all...
Homogeneous charge compression ignition (HCCI) engines create a cleaner and more efficient power source for either stationary power generators or hybrid vehicles. Control of HCCI engine, however, is difficult since its ignition cannot be actuated directly. For the purpose of model-based analysis and controller design, a model for a single cylinder HCCI engine with electric mechanical valves (EMV)...
This paper presents a new modular hybrid power system incorporating photovoltaic and small scale wind generators connected to an AC grid formed by a doubly fed induction generator driven by a variable speed diesel generator operating in the optimum fuel efficiency mode. Preliminary experimental and simulation results of the DFIG are included. The system is proposed to replace medium scale diesel-only...
In this paper the optimization of wearable power system comprising of an IC engine, motor/generator, inverter/rectifier, Li-battery pack, DC/DC converters, and controller is performed. The Wearable Power System must have the capability to supply an average 20 W for 4 days with peak power of 200 W and have a system weight less then 4 kg. The main objectives are to select the engine, fuel and battery...
