1. 「濕式噴射淨化機構降低漁船廢氣排放之開發研究」：
This project aims to construct an eqipment of reducing waste gas of internal combustion engines. The water jet method will be adopted that mixes the water jet with the pollutant. The measurements will be performed in the laboratory to analyse the effectiveness of the proposed method. The reduction of pollutant is expected to reach 15%, including CO2, NOx, and so on.
2. 「漁船用柴油引擎廢氣排放減量裝置之開發 (一)」：
The mankind is in the process of pursuing "environment right" , the fishing boat uses the exhaust gas emissions of diesel engine, having already been subjected to widespread concern. In order to make the diesel exhaust gas emissions of native fishing boat match environmental protection laws in the world, this project draws up to make use of exhaust gas recirculation (EGR) principle, developing a set of new exhaust gas to reduce to equip, reducing fishing boat diesel the NO emissions of the engine by period, reaching to match a lately international convention to prevent the provision of air pollution from to the ships.
This research designs the exhaust gas recirculation device, application at horsepower is 1000 HPs, total the tonnage is 200 tons above fishing boat, the whole system structure includes EGR water cooler, Venturi, EGR control valve, EGR filter, and intake air resonator. This system with EGR rate 35% for design basis, then decide design parameter inside the spare parts, finally designing spare parts engineering diagram by computer painting software.
3. 「漁船電力推進微電腦控制系統之研發」：
The use of electric propulsion for fishing boats can help in manipulation improvement, velocity control, vibration and noise reduction, system downsizing and maintenance reduction. To maximize the performance of the propulsion system, control and manipulation is one of the key factors. Therefore, this project employs microcomputers and the so-called 'steer-by-wire' concept for implement. However, control of engine propulsion is the first target to fulfill in this project by using a microcomputer and programming with a man-machine interface. Therefore, the system can be downsized and the performance can be enhanced. This project will further design a microcomputer-based control system for electric propulsion system. The project objective is listed below: 1. Design and implement of microcomputer control for an engine propulsion system. 3. Design of microcomputer control for an electric propulsion system.
4. 「漁船漁獲裝載穩度監視系統開發之研究」：
The stability has a great effect on the security for ships. All the new ships have been tested. Stability must be up to the standard. But when the cargo been put on the different location, the stability will change by it. When the cargo has been placed in the wrong way, the center of gravity of the ship will raise up, and the stability also the security of the ship reduce sink down in the meantime.
This project focuses on the relationship between the location of the cargo and the stability of the ship. Development for monitoring stability of fishing boat derived from cargo loading. By the program crewman can get the information about stability of boat which derived from cargo loading, then correct it. It insures the security of the ships.
It is a combination the programs that 3Ds MAX, Visual Basic, EON and”船舶設計計算”. Drawing a virtual shape of ship from the information of real ship by 3Ds MAX. Analyze hydrostatic table and cross curve table from real ship lines by ”船舶設計計算”. Input the virtual shape of ship to the program EON, and show the situation for the ship which has the cargo loading to base on ship data. The program interface is VB. By the different property of cargo, we use VB to calculate the ship property after cargo loading, send virtual message about ship to EON.
The program will warn of the Trim over limit too much and when the stability of the ship is unbalanced. When the way to place cargo will make the ship instability, then the virtual one will upset down. |
