The effects of recirculated exhaust gas on the wear of cylinder liner, piston and piston rings have been investigated by the experiment with a two-cylinder, four cycle, indirect injection disel engine operating at 75% load and 1600 rpm spped. For the purpose of comparison between the wear rates of two cylinders with and without EGR, the recirculated exhaust gas is sucked into one of two cylinders after the soot among exhaust emissions is removed by an intentionally designed cylinder-type scrubber equipped with 6 water injectors(A water injector has 144 nozzles of 1.0 mm diameter), while only the fresh air into another cylinder. These experiments are carried out on the fuel injection at a fixed 15.3˚BTDC timing. It is found that firstly the mean wear amount of cylinder liner with EGR is more increased in the measurement positions of the second half than of the first and the mean wear amoount without EGR is almost uniform regardless of measurement positions, secondly the wear rates of the first and second piston ring(compression ring) thickness with EGR are more than twice, but the wear rate of oil ring thickness without EGR is more increased than that with EGR, and finally the wear rate of piston skirt with EGR is a little bit increased, but the piston head diameter is rather increased owing to soot adhesion and corrosion wear, and especially larger with EGR.

본 연구는 이러한 종래의 온-오프제어와 아날로그제어의 단점을 보완하기 위하여 온실환기냉방 제어계의 수식모형에 근거한 디지탈제어기법을 도입하므로서 정확한 환기제어 방법을 도출하여 환기작동기의 최적 가동기법을 정착하여 에너지 효을을 제고시키기 위해 수행되었다. 연구는 소형 모형 온실에 계측제어 장치를 설치하여 환기냉방제어계의 온도 예측 수식모형 동정에 필요한 파라미터 식별을 실행하였고, 그 결과를 기초로 하여 비례적분미분제어법을 이용한 환기 냉방제어 실험을 실시하였던 바, 그 적용가능성이 입증되었다. In this study, digital control method baaed on the mathenatical model of ventilating cooling system for greenhouse was introduced. This system was expected to improve the weak point of the ON-OFF control system. Investigations were made to figure out the way of precious ventilation control which is the foundation of optimum operation technique of ventilation system in raising the energy efficiency. Parameters of mathematical model of temperature prediction for the ventilating cooling system were identified in a model greenhouse built for this study. With results from the parameter identification, operation simulations on ventilating cooling systems were carried out by proportional integrated derivative control(PID control). And then verification of the simulation results were made through the proto-type field experiments using control method.

황광성,문성동 진주산업대학교 1997 산업과학기술연구소보 Vol.- No.4

Using a 4-cyclinder engine having 1,800cc of exhaustion capacity, compositions of the exhausted gases from mixed liquid fuels containing 10, 20, 30, or 40% methanols were as folles : 1. With increasing the equivalence ratio (ER), the brake thermal efficiency (BE) decreased. with the greatest efficiency observed appoximately at 0.8 of ER, whereas the torque exhibited a trend opposite to that of BE with the highest efficiency found at near 1.2 of ER. 2. Concentration of NOx gas decreased with increasing methanols percentage ; the lowest NOx gas concentration was observed at 1.20 of ER. 3. Concentration of CO gas exhibited a biphasic trend : it increased up to 20% of methanols and thereafter declined. 4. The amount of exhausted HC from the mixed fuel was comparable to that of pure gasoline up to 10% of methanols ratio but decreased at or above 20% of methanols ratio, which seems to have reasulted from a difference in the oxygen content of the fuels.

黃光性,許南秀 진주산업대학교 1988 論文集 Vol.26 No.-

This study was initiated to evaluate the performance of 8ps Diesel engines detached from power tiller and to find the possibility of offering a rational guide in selecting and inspecting the engines. For this purpose. 8ps engines of 3 different engine builders were used in measuring the maximum power, normal power. torque and fuel consumption rate at different engine speeds. The result of the study are summarized as follows: 1. The average of the normal powers specified by the 3 engines was 8ps at 2,200rpm. However, in the test the average power of 3 engines at 2,2000rpm was 7.9ps, 7.6ps and 7.8ps which was almost same. And 8ps which was presented as a rated power was measured around 2,230rpm. 2. The average of the maximum powers specified by the 3 engines was 14ps/2,400rpm, 12ps/2,200rpm, and 11ps/2,200rpm. However, in the test the average power of 3 engines at 12.3ps, 11.3ps and 10.6ps which was lower than the average of specified powers at the same engine speed. 3. Fuel consumption rates normal power was 1,900rpm and maximum power was 1.800rpm. Fuel consumption rates of 3 engines was almost same. 4. Torque was increased about 0.1kg.m/100rpm untim 2,000rpm at normal power and 2,100rpm at maximum power, after that time it was decreased gradually.

In order to utilize the basial data in efficiently using and selecting power tiller by measuring expense of it, The results investigated the expense of use by each horsepower except field efficiency were summarized as follows: 1. Fuel consumption time by each kind of power tiller per 110㏄ was 4.6 minutes 5ps, 4.4 minutes 6ps, 3.4 minutes 8 ps and 2.8 minutes in 10ps. As the horsepower is high, Fuel consumption time was short. 2. Specific fuel consumption(g/pshr) by each kind of power tiller was 253.6 5 ps, 220.9 6 ps, 212.3 8ps and 208.4 in 10 ps. As the horse power was low, It was high. 3. It was suggested that It be more economic to utilize the power tiller of 6ps than 8 to 10ps 4. The net expense of use except field efficiency was more cut down by 76,000 won in 6ps than in 8ps, and 125,000 won than in 10ps.
