Substitutable fuels from a renewable source are one of the alternatives to reduce emissions. Neat biodiesel from based palm oil (B100) can reduce emissions from higher oxygen content to be more complete combustion. The disadvantage of neat biodiesel is lower thermal efficiency from an advancement ignition. To improve this problem, adding bioethanol produced from agriculture products into neat biodiesel by weight ratio as B100E5 (95% B100 with 5% bioethanol) and B100E10 (90% B100 with 10% bioethanol). Hence, the focus of this research is to examine the combustion and emission characteristics, including engine performance, of bioethanol blends into neat biodiesel fuels (B100E5 and B100E10) compared with neat biodiesel (B100). All samples were tested at an engine load of 140 NM with constant engine speeds of 1000, 1500, and 2000 RPM on a diesel engine. The results of bioethanol blends into biodiesel fuels...

Existing transportation systems have been extensively developed to serve a variety of needs. While most systems of agricultural product transportation are designed for multi-purpose functions, farming activities and agro-processing industries may need specific types of transportation. The main focus of this study was to find a design to fulfil customer transportation requirements for oil palm fresh fruit bunches (FFBs). Since more than 70% of Thai oil palm farmers operate at a small scale with an average oil palm plantation area of 3 to 5 ha, the challenge is not to further develop advanced technology to transport FFBs, but to develop a new design approach that fits the basic needs of farmers. Kano model, based on custome...

Unfortunately the battery testing presently does not represent the realworld condition, in which the battery load profile comprises complex charge-discharge wave. Therefore in this study, the load profile of batteries for electric vehicles was investigated. An integrated simulation and testing approach is used to predict the battery load. In simulation the battery load profile is calculated based on the utilization of vehicle and battery model. The present vehicle and battery model are developed using a vehicle dynamics technique and equivalent circuit modeling technique respectively, whereas the model development is focused on a specific vehicle which converts conventional propulsion into pure electric propulsion. The results are demonstrated through the current profile of advanced batteries subjected to standard driving cycles. With this approach, the...

This unwanted heat could be taken out of the unit by a water coolant. This work deals with the effect of geometrical parameters on heat removal capability of the unit. The case of study can be divided into three parts. Part one is on the effect of cooling duct size. Part two is on the effect of base diameter and part three is on the number of cooling ducts. The model which has the best result among others is the 7.5 millimeter duct size with one cooling duct in the model of 30 centimeter of base diameter.

Based on the survey of the Road Safety Group Thailand in 2017, at least one student got injury by school transport each day. A recent survey also revealed that the number of private hire pick-up trucks as school buses in Thailand, especially in upcountry areas, is increasing due to its lower cost in comparison to that of a van or a minibus. To get the optimal capacity as vans or minibuses, pick-up trucks’ roofs were converted for the highest passenger number at the lowest cost. Therefore, to focus on the strength of converted pick-up truck’s roof is required to help reduce losses in terms of both human injury and inside cabin’s damage due to rollover accidents. This article demonstrates an approach to design the vehicle’s roof as a superstructure of school pick-up truck based on design inputs, including structural s...

The test protocols used in this work follow a standard defined by the International Organization for Standardization (ISO). This standard is titled 'Prosthetics* Structural Testing of Lower-Limb Prostheses*Requirements and Test Methods' or shortly called ISO 10328: 2006. The purpose of this standard is to guarantee that a prosthesis is able to survive a random severe load and has a sufficient fatigue life. Finite element method, which is a numerical technique used to model a physical system, is employed as a primary computational tool to simulate the prosthesis under the tests. The method of explicit nonlinear transient stress analysis is applied to determine the strength of prosthesis. Consequently, the finite element model reveals the stress distributions induced on the prosthesis and predicts its fatigue life. Besides, to examine the accuracy of the model, the simulation results, particularly structural strains, are validated with those obtained from experiments. In each testing condition, five repetitions are performed to ensure the result consistency. The validation results confirm the fidelity of the proposed finite element model. The average of absolute percentage errors between the simulation and experimental results in all testing scenarios is estimated to be 22%.
