Although Thailand is a main producer of oil palm fresh fruit bunches (FFBs), there is no specific vehicle for these plantation farmers which fits the harvesting and transportation requirements. The voice of palm oil plantation smallholders was surveyed in several regions of Thailand in order to develop and design a suitable transportation system. As a result, most of samples need a farm truck, which can carry a maximum payload of three tons and can survive on the rough terrain in farm. To meet these requirements, the new three-cylinder engine with more power, the 4WD driveline, the front and rear axles with full load capacity of over 5 tons are introduced in the new farm truck. In addition, the suspension system of the farm truck, which was mostly designed without engineering knowledge, is to be developed in accordance with the vehicle layout, the upper body weight, and the vehicle dynamics in vertical direction. The suspension engineers face many challenges.

The main emphasis for a Commercial vehicle design which was focused on fuel-economy and durability does not fulfill the increasing customer expectations anymore. Commercial vehicle designers need to focus on other vehicle aspects such as steering, ride comfort, NVH, braking, ergonomics and aesthetics in order to provide car like perception to truck, bus drivers and passengers during long distance drives. Steering system on long wheel base trucks must perform many functions: First and foremost, it needs to provide a reasonably small turning radius so as to achieve good maneuverability. Second, it also needs to have geometrical compatibility with suspension system so as to minimize bump steer and achieve good handling control as well as to minimize tire wear. These Requirements contradict each other & hence a suitable "Tradeoff" is needed for achieving these targets.

This paper investigates the way to control the fuel injection timing for diesel engine running with biofuels. The research was conducted by experiments. Two fuels, B100 and B2, were used for experiments. The engine was operated under the ESC 13 modes operation condition. In each mode, five different injection timings were tested and the associated engine performance data were recorded. During the process, the cylinder pressure variations were also captured by the pressure transducer and the pressure data were then used to calculate the indicated thermal efficiency and combustion characteristic, including the heat release rate and the crank angles from the beginning of combustion to the point that 50% of fuel was burned (CA50). By comparing the measured torque and brake thermal efficiency, the best CA50 can be determined at each operating mode.

Nowadays we are facing with fossil fuel crisis and global warming problems and need to find the solutions for these problems. To reduce the usage of fossil fuel, the increasing of efficiency is important. In some country, they use the Wide-Base-Single tire for trailer because it has less rolling resistance than dual normal tire. In Thai industries also use many trailers. If the efficiency of trailers is increase, it will have great effect to the fuel usage in Thailand. But when the tires have been changed, stability of the trailer also changed. To make sure that the trailer stability and controllability is not lower than the standard, the trailer with Wide-Base-Single tire will be investigated. This thesis will focus in trailer dynamics and stability simulation to compare the result of trailer between the dual normal tire and Wide-Base-Single tire.

The need to develop products faster and to have designs which are first time right have put enormous pressure on the product development timelines, thus making Computer Aided Optimization one of the most important tool in achieving this targets. In this paper, a Design of Experiments (DOE) study is used, to gain an insight as to, how changes to different parameters of Front Suspension & Steering of a Passenger Bus affect its kinematic properties & thus to obtain an optimized design in terms of Handling parameters such as bump steer, roll steer, percent Ackerman, Lock to Lock rotation angle. The Conventional Hit & Trial method is time consuming and monotonous & still is an approximate method, whereas in Design of Experiments (DOE), a model is repeatedly run through simulations in a single setup, for various combinations of parameter settings. Effects and interactions of the design variables of the model are then studied, which provides an insight to help design an optimized model.

A vehicle of interest in this paper was a light agriculture truck operated by a 14 hp single cylinder engine. Its chassis type is a ladder frame with Hotchkiss setup suspension. In Thailand this particular truck is also called E-TAN and is mostly driven on rough terrains under agricultural applications. To improve the current design, the information on a structural strength of the truck frame is required. A combination of physical tests and computer simulations was arranged to obtain reliable predictions of stress generated in the frame under load. For the simulations, a Computer Aided Design (CAD) model of the ladder frame included a main frame and a sub frame, on which an engine and transmission system would be mounted. Leaf spring mounting brackets were modeled as well as shock absorbers mounting structures. A completed Finite Element (FE) model of the frame contains 29,730 quadratic shell elements and 34,055 nodes.

This work describes the evaluation of the aerodynamic forces acting upon a road going sport motorcycle (modified for racing purposes) during a high speed, high lean angle cornering manoeuvre using commercial computational fluid dynamics software. The subject of motorcycle cornering aerodynamics is currently one not widely covered in literature. The research presented in this paper aims to provide a basis for investigations into the improvement of motorcycle cornering performance through aerodynamic modifications. Results were obtained through steady-state RANS simulation, using the k-epsilon turbulence model, of the vehicle during a cornering manoeuvre at a constant speed of 38 m/s with the lean angle varying from 45 to 55 degrees from vertical. This manoeuvre was analysed in 1 degree intervals. Large lift forces were observed, with centre of pressure located near the front of the motorcycle, which increase as the motorcycle leans further.

The main purpose of this research is to investigate the effect of volumetric efficiency of a four cylinder four stroke engine with different kinds of design parameters. There are several methods to improve the volumetric efficiency, such as changing the valve lift, the valve timing, the intake pipe parameters and setting the Helmholtz Resonator. In the research, we focus on two design parameters of intake system, adding Helmholtz Resonator and the valve timing. In Helmholtz Resonator part, we compare results of two conditions, with and without Helmholtz Resonator. Under the situation with Helmholtz Resonator, the position and the volume are also considered. And analyze the effect of the different kinds of design parameters on the volumetric efficiency. The position one of the resonator is between the gas storage tank and the air filter. There is only one intake pipe, so only one resonator is set on the pipe.

The method of analyzing the best thin-wall-tubed cross-sectional shape of impact attenuator for student formula is proposed in this study by ways of simulation and validation in any case following SAE rules. We performed using ANSYS-Explicit Dynamics method for simulation and compared the result like energy absorption among six cross-sectional shaped circle, square, hexagon, cone, square pyramid and hexagonal pyramid. The results show that at the certain deformation, the circle-shaped absorbs energy higher than others. Cone, square pyramid, hexagonal pyramid, hexagon and square can absorb the energy compare to circle as 68.5%, 53.9%, 47.8%, 30% and 1.8% respectively. We compared the result of circle cross sectional case to the quasi static experiment and found that it was in the same trend.

This study is compares the effect on fuel consumption between Wide-base single tires and Dual tires semi-trailer truck. Our assumption is focused on variation of tread width impact on fuel consumption. Rolling resistance of tire is calculated and measured by Drum tester following UN ECE R-117 standard, and then predicted the rolling resistance coefficient by using the finite element analysis ( FEA ) with the simulation software. After that, predicted the fuel consumption with computer simulation program. This testing is also considered as international research, reports and followed to acceptable standard. From the expected result of this study, wide tread width should be consume fuel lower than narrow tread width because low rolling resistance coefficient indicate the reducing of fuel consumption when using Wide-base single tire. This study is expected that can be used as reference and motivation for a changing of government regulations regarding the use of Wide-base tires.

The Flame Ionization Detection (FID) is the most widely used and sensitive technology for the measurement of total hydrocarbons (THC). The fuel used for the flame in the FID analyzer is a mixture of hydrogen and helium in the ratio of 40:60 in the automotive emission testing of hydrocarbon determination. Helium is the second most abundant element in the universe; however, its consistent supply over long run continues to be marked by uncertainty. Environmental protection Agency (EPA) revised 40CFR part 1065 in April 2014 to include Nitrogen balance gas as an alternative option of He with H2 for FID Fuel in the automotive industry for hydrocarbon emission testing. Blend tolerance of the FID fuel has also been decreased to 40±1% (0.39 to 0.41mol/mol) H2 in the revised regulations to minimize its impact on analyzer response. The availability of nitrogen as FID fuel balance gas was studied and compared with He balance gas to understand the relative impact on emission testing.

Every organization needs to effectively manage its data collection and analysis process in order to efficiently collaborate on a global scale. This paper describes a model for standardizing the data collection and analysis process developed in Caterpillar and specifically deals with two challenges in this regard: 1. A method for standardization of the nomenclature of different physical parameters measured during a typical engine test. This is essential for processing data from various facilities spread across the globe especially when we need to run them through a standard set of calculations. The process of storing and performing a given set of complex processes on the data while allowing analysts to view the steps of the processing in a transparent intuitive manner is also described in the paper. 2. Building on the first point, the paper also describes a process for performing a standard set of data quality checks on data as it is being collected.

Abstract In order to minimize the development and production costs in the automotive industry, despite steadily increasing variety of models and applications offered by the OEMs, the pressure on standardization of components and production processes is increasing continuously. As a direct consequence, modular engine families are already established with high degrees of common parts and kits as well as standardized interfaces for all vehicle platforms by most manufacturers these days. At the same time, the world adopted and announced massive legal demands concerning the reduction of CO2 emissions for the entire vehicle fleet. In addition to the optimization of the combustion process, the exhaust gas aftertreatment and thermal management, the use of improved and more resilient materials for higher reduction of mechanical friction leads to a significant amount of the realized lowering in fuel consumption respective CO2 emissions.

Abstract The present paper is an introduction to a novel rotary valve engine design addressing the major downfalls of past rotary valves applications while permitting the typical advantages of the rotary valves. Advantages of the solution are the nearly optimal gas exchange, mixture formation, ignition and combustion evolution thanks to the large gas exchange areas from the two horizontal valves per engine cylinder, the good shape of the combustion chamber, the opportunity to place a direct fuel injector and a spark or jet ignition device at the centre of the chamber. The novel engine design also permits higher speed of rotation not having reciprocating poppet valves and the reduced friction losses of the rotating only distribution. This translates in better volumetric efficiencies, combustion rates and brake mean effective pressures for improved power density and fuel efficiency. Additional advantages are the reduced weight and the better packaging.

The present day sustainable transport solutions demands bringing down the pollution levels and fuel costs. Need for alternative fuels and alternative powertrains arises from this. Many of these alternative solutions are in their premature states of research and are facing a lot of challenges in implementation. Though electric vehicles (EVs) are supposedly more environment friendly, EVs cannot completely replace the ease of use and ease of refueling that a conventional IC engine offers. But the switching to a new technology is inevitable and so a compromise between today’s IC engine technology and Electric Vehicle technology will be a good option for this transition period. Thus begins the era of Hybrid Electric Vehicle (HEV) - a technology which uses both conventional Internal Combustion Engine coupled with an Electric Motor for its working. Hybrid cars are already available in the market.

Abstract In this study, an alternate way of development and implementation of control strategy for torque split of a Hybrid Electric Vehicle (HEV) is proposed. The control strategy evaluates each and every operating point for Internal Combustion Engine (ICE) and electric motor-generator (E-machine) corresponding to all possible torque split combinations at present time instant and finally chooses one combination with the least cost function, which is estimated by converting electrical energy into equivalent fuel consumption[2]. Henceforth, the control strategy is able to perform real time iterations to choose the E-machine and ICE torque combinations with least effective fuel consumption also referred herein to as the optimal operating points. As a result, by running the vehicle at optimal operating points, overall fuel consumption over the complete drive cycle is reduced.

Abstract A feature of the present state of the Russian agricultural industry is that productive resources (tractor pool, arable land area and number of workers involved) are diminishing and the reduction does not have a quantified value. In the prevailing conditions of limited resources, agricultural enterprises are forced to operate tractors beyond their amortization periods on a massive scale, which results in an unpredictable service life. This situation calls for an assessment of the optimal composition of the tractor pool in terms of number and age. By way of a solution to this problem, the given article presents a methodological approach as to the analysis of two opposing factors.

Future doors require light weight, cost efficient and acoustic optimized solutions. Current steel doors offer only a small range of possibilities in these areas. With the use of Aluminum doors the weight will be reduced but production complexity and costs will be increased. A modular door approach supports all of these future demands. Door modules have set milestones for door concepts already in the past. Due to technological progress, door modules are more relevant than ever. The use of reinforced plastics allows a high degree of design freedom with high functional integration features (i.e. window regulator rails). In addition to weight reduction of up to 1,5kg per door the complete production process comes leaner with a higher grate of quality. Finally the acoustic performance of a door system can be adjusted for improving the sound quality of speakers and noise reduction.

Abstract Typical software that is used for engine test result analysis include spreadsheet (MS Excel) and statistical software (Minitab, MS Excel), data modelling applications (MS Excel, Matlab), and post processing tools for plots, tables etc. Open source software has come a long way since its inception, and is now at a stage where it can provide a suitable alternative to many commercial software packages for data analysis. The paper will describe the areas of concern and the inherent benefits to using open source software. It evaluates the feasibility of incorporating these open source tools into data analysis packages for Engine Development by breaking down the process of data analysis into specific software requirements and then evaluating each of the open-source alternatives against these requirements. The paper will conclude by describing a practical strategy when converting an existing data analysis process over to its open-source equivalent.
