이민호 ( Lee¸ Minho ) 한국행정학회 2021 韓國行政學報 Vol.55 No.3

과거 규제품질관리의 목적에서 전 세계적으로 규제영향분석의 도입이 활발히 진행되어 왔으며, 그 핵심적 항목으로 규제비용편익분석의 중요성이 강조되었다. 최근에는 정책과정에서의 소통과 참여가 강조되면서 규제협의에 대한 측면도 규제품질관리의 중요한 요소로 주목되고 있다. 본 연구는 규제품질관리제도의 중요한 정책수단으로 비용편익분석과 이해관계자 협의의 활용이 어떻게 이루어지고 있으며, 이들 간에 어떠한 상호관계를 나타내는지 실증적으로 분석하고자 하였다. 예비분석 차원에서 OECD의 iREG 조사결과와 우리나라 규제혁신평가 결과를 활용한 분석 결과는 규제비용편익분석과 규제협의 수준이 상당히 긍정적인 상관관계를 갖고 있는 것으로 확인되었다. 이어진 본 분석에서는 2016-2019년까지 수행된 4,284건의 규제영향분석서를 대상으로 다각적인 분석을 진행하였으며, 전반적으로 이해관계자에 대한 협의가 활발히 진행될수록 규제비용편익분석의 수준이나 충실도가 높아지는 것을 확인할 수 있다. 또한 규제 비용편익분석 수준에 대한 도구변수를 이용한 분석 결과, 반대 방향에서 규제비용편익분석의 충실도가 높아질수록 이해관계자에 대한 협의도 활성화되는 것으로 파악되었다. 이러한 결과는, 정부규제의 품질수준을 높이기 위한 경제적 분석과 정치적 논의의 수행이 선순환된다는 기존의 이론적 논의를 실증적으로 확인하고 있으며, 향후 양자의 균형적인 제도의 발전 및 활용, 개선이 이루어질 필요성을 제기한다. Since regulatory impact analysis was actively adopted worldwide for the purpose of regulatory quality management in the 1990s, the importance of regulatory cost-benefit analysis has been emphasized as a key policy tool. However, recently, as public communication and participation in the policy process have been more emphasized, regulatory consultation is also drawing more attention as an important tool for regulatory quality management. This study empirically investigates how well cost-benefit analysis and regulatory consultation with stakeholders are utilized as policy tools and what kinds of relationships they have in the current regulatory quality management system. For preliminary analysis, OECD iREG survey results and departmental evaluation results for regulatory innovation in Korea are utilized. They reveal a positive relationship between cost-benefit analysis and regulatory consultation. The results of the subsequent main analysis of 4,284 RIA statements in 2016 -2019 also confirm that more active regulatory consultations have a positive effect on the possibility of conducting a more substantial cost-benefit analysis. In addition, according to the results of a regression analysis using the instrument variable for enhanced cost-benefit analysis, it turns out that the positive influence can also be applicable in the reverse direction. In conclusion, these results empirically confirm the existing theoretical discussion that the policy tools of economic analysis and political discussion have synergistic effects for increasing the quality of government regulations, and suggest the need for balanced development and utilization of these economic and political tools in the regulatory management system.

A chassis dynamometer test cell is employed along with a CVS (Constant Volume Sampler) system to test for both vehicle exhaust emissions and for fuel economy. The current fuel economy test method for gasoline and diesel fueled vehicles is called the Carbon-Balance method, and it works by testing the vehicle exhaust emissions for all carbon-containing components. Through conservation of mass, the carbon that comes out as exhaust must have gone in as fuel. However, there are significant differences between the real vehicle fuel rate(fuel flow metering method) and the CVS measured fuel consumption(carbon-balance method) during vehicle fuel economy tests. This is a concern because a different property characteristics of vehicle fuel are used during a test. It is important to be able to relate mass emissions to mass fuel consumption in order to understand and control vehicle engine performance. In addition to the standard test equipment for vehicles, a highly accurate fuel flow meter is installed that measures the mass of fuel consumed by the engine during chassis dynamometer tests. A diesel vehicle was tested over CVS-75 mode (standard Fuel Economy protocols), where it is found that the fuel flow meter mass measurements correlate with the carbon-balance fuel consumption results measured with the CVS. Experiments are performed using two different test method where equivalent results are obtained. The carbon-balance fuel economy performance of the CVS is compared to that obtained with a fuel flow metering method. This paper will explain the principles behind the new testing methods as well as the equipment required to accurately test vehicle fuel consumption. The techniques have been optimized for the chassis dynamometer, and the current bio-diesel fuel configuration is given as an example.

GHP engine is recognized as a promising way to meet better energy efficiency improving and exhaust gas reduction. In generally, Natural gas engine for GHP should be mostly based on 4 stroke water-cooled diesel engine which has high power in low speed, but sometimes could be based on automotive LPG engines because of easy modification.<br/> However, LPG fuel is different from NG fuel in chemical disposition. Therefore, the mixer design of GHP engine is required, because the mixer of LPG engine is impossible to use. Also, in order to obtain low emission and low fuel consumption simultaneously in a GHP engine. the influence of a mixer at the fuel supply system is analyzed.<br/> This study is investigated to the influence of mixer shape at the fuel supply system of GHP engine. The designed Mixer is analyzed through a CFD analysis and GHP natural gas engine test.<br/>

Lean burn gasoline engine, classified into port injection and direct injection, is recognized as a promising way to meet better fuel economy. Especially, gasoline direct injection engine is becoming increasingly popular due to their potential for improved fuel economy and emissions. Also, GOI engine has the advantages of higher power output, higher thermal efficiency, higher EGR tolerance due to the operation characteristics of increased volumetric efficiency, compression ratio and ultra-lean combustion scheme. However, GDI engine has many difficulties to be solved, such as complexity of injection control mode(fuel injection timing, injection rate), fuel injection pressure, spark timing, unburned hydrocarbon and restricted power.<br/> This study is investigated to the influence of spark timing, fuel injection position and fuel injection rate on the combustion stability of GDI engine. Piston shape is constituted the bowl type piston. The characteristics of combustion is analyzed with the variations of spark timing, fuel injection position and fuel injection rate (early injection, late injection) in a GDI engine.<br/>

In the future, automotive engine should satisfy the more stringent CO₂emission regulation without trading off the higher thermal and combustion efficiencies. Natural gas is one of the most promising alternative fuels for automotive engine, because it can reduce exhaust gas emissions than gasoline, diesel and LPG fuel, and can be used in conventional engines with a little modification. But, the performance of natural gas engine is fewer than gasoline, diesel and LPG fuel engine. Therefore, natural gas engine is requires a different methods for the improvement of engine characteristics such as engine power, fuel economy, brake thermal efficiency and exhaust gas emissions. Low compression, high expansion ratio could be one of the solutions in this context, which can be realized in automotive engines by making the expansion period longer than compression period.<br/> The objective of this study is to examine the effect of low compression, high expansion ratio on engine characteristics such as engine power, fuel economy, brake thermal efficiency. To realize low compression, high expansion ratio in engines, intake valve timing was varied by applying several cam-shafts with different cam profiles. Also a supercharger was adopted to increase the power. These experiment results may be utilized to develop natural gas engine of high efficiency and low emissions for automotive.
