“…The conduction loss, which is caused by a resistance during the flow of current inside a MOSFET (t on ) when the switch is open, is a major loss along with the switching loss of a MOSFET [Equation (7)] [17]. The conduction loss at a busbar was calculated using the current value and the busbar resistance [Equation (8)] [17].…”

“…Because the heat generated from inverters differ depending on the inverter materials and the cooling structure, many studies on inverters are carried out in addition to studies on motors. Mallik et al [8] introduced various thermal management materials that can be used for the electronic control unit of power electronics for cars. They also contrasted the types and features of the housing and thermal interface materials (TIMs), which are crucial design factors affecting heat dissipation.…”

Abstract:If the integrated starter generator (ISG) motor and inverter operate under continuously high loading conditions, the system's performance and durability will decrease and the heat dissipation requirements will increase. Therefore, in this study, we developed two cooling designs for the ISG motor and inverter, and then carried out both a model analysis and an experiment on the fluid flow and thermal characteristics of the system under various operating conditions. As the outdoor temperature increased from 25 °C to 95 °C, the coil temperature of the air-cooled motor increased by about 82 °C. Under the harsh-air condition of 95 °C, the coil of the air-cooled motor increased to a maximum temperature of about 158.5 °C. We also determined that the temperature of the metal-oxide-semiconductor field-effect transistor (MOSFET) chip in the liquid-cooled inverter increased to a maximum temperature of about 96.8 °C under a coolant flow rate of 4 L/min and a coolant temperature of 65 °C. The observed thermal performance of the ISG motor and inverter using the proposed cooling structures was found to be sufficient for heat loads under various real driving conditions for a hybrid electric vehicle (HEV).

“…These composites, which are preferentially fabricated via gas pressure-assisted liquid metal infiltration, are known to exhibit excellent thermal properties [1][2][3][4][5][6][7][8][9]. Their thermal expansion coefficient, which is mainly determined by the volume fraction of present phases, can be tailored to desired values (4-5 ppm/K) for many metal-diamond combinations.…”

As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. TC is mainly governed by the Al-diamond interface characteristics, which are determined by a proper control exerted through processing conditions. Albeit a very low cost and low quality diamond is used, a high value of 667 W/mK has been measured for Al/diamond composites produced under optimized processing conditions. Values above 740 W/mK are reported for the best diamond quality explored in this work. These experimental results, which assign the control over TC mainly to the interface conductance, suggest that many of the limiting values of TC reported in literature for the different explored metal-diamond systems, need to be reconsidered by proper precise control of interface evolution.

“…The injection duration and duty cycle were computed and corrected from several inputs, such as air temperature, throttle position, manifold pressure, lambda sensor and etc. [1,2]. There are also other methods that utilize a pre-programmed lookup table as a source of input as well as for correction factors.…”

Abstract:The primary function of an electronic control unit (ECU) of an engine is to calculate the amount of fuel to be delivered into the combustion chamber. The injection duration and duty cycle of the injector will be based on several sensors whose signals the ECU will process to ensure the best engine running condition. However, to study new injection and combustion strategies, where such operation is unavailable in standard ECU, a custom-built fuel injection control system need to be made. This paper describes the development of a fuel injector signal controller, which is being used for internal combustion engine experiment or for the evaluation of any fuel injector static flow rate. Herewith a new term Injector-Volume Ratio (IVR) was introduced to assist the development process. Using the custom-built fuel injection controller, the static flow rate of an injector for a single cylinder 125cc motorcycle engine was determined in accordance to SAEJ1832. From the experiment, the IVR value is proven useful in choosing the right size of a fuel injector to fit any specified engine displacement of a spark ignition engine.
