There are several types of environment friendly vehicle being developed by auto manufactures. HEV (Hybrid Electric Vehicle) is most applicable one among them in actuality. HEV has two power sources, one is an internal combustion engine, the other one is an electric device. The HEV is developed for reducing fuel consumption and emissions. We selected the diesel engine as a main power source of HEV. The tests were carried out under different driving cycles which was CBDBUS (Central Business Driving Bus Schedule) and HWFET (Highway Fuel Economy Test). This research presents a simulation for the fuel economy and the emission of heavy diesel hybrid vehicle according to the SHEV (Serial Hybrid Electric Vehicle), PHEV (Parallel Hybrid Electric Vehicle), Plug-in SHEV and plug-in PHEV.

전 세계는 지구온난화와 고유가시대를 맞이하여 배출가스 규제에서 온실가스와 연비 규제로 확대되면서 그린카라는 새로운 용어가 등장하였다. 원유 고갈과 원전 불안으로 수송연료에도 신재생 에너지와 세일가스 등장에 큰 기대를 걸고 있으며, 새로운 에너지원을 사용하는 전기자동차와 수소연료전지 자동차의 개발도 활발이 진행되고 있으나 자동차시장의 형성은 각종 규제의 만족은 물론이고 경제성, 안전성, 편리성 등이 수반되어야 한다. 향후 세계 자동차시장은 에너지의 수급 사정과 시대의 요구 조건에 따라 크게 좌우되므로 각 국가별 여건을 고려하여 단계를 구분해서 그 시대에 가장 적합한 그린카 차종이 무엇인지를 신중하게 분석하여 산업화 정책을 추진해야 할 것이다. 이러한 관점에서 최근 기계연구원이 주축이 되어 개발하여 운행 중인 디젤하이브리드 자동차를 중심으로 세계 그린카 개발동향을 소개하고자 한다.

최근 10년동안 지구환경 문제는 인류가 하는 모든 활동에 있어 기본전제가 되고 있다. 지구온난화 문제로 인해 자동차의 $CO_2$ 배출량을 줄이는 문제가 최근 수송기계 분야의 초미 관심사가 되고 있으며 온실가스 문제와 석유자원 고갈에 따른 대체에너지 문제에 따라 자동차 산업은 큰 전환기를 맞고 있다. 세계 각국에서 이산화탄소 배출규제가 법제화되면서 내연기관 중심의 자동차 기술은 그린카(친환경자동차) 기술로의 패러다임의 변화를 보이고 있다. 그린카는 전기자동차, 클린 디젤차, 연료전지차 정도로 대분류되며 전기자동 전기자동차(EV), 하이브리드 전기자동차(HEV), 플러그인 하이브리드 전기자동차(PHEV) 등으로 분류된다. 이미 그린카의 양산이 수년전부터 활발하게 진행되어 왔으며, 최근 2~3년내로 각국의 major급 자동차 메이커에서 이에 대한 양산 계획을 속속 발표하고 있다. 이러한 전 세계의 그린카 정책동향과 국내 그린카 활성화 정책 및 현정부의 광역경제권 선도산업으로 추진중인 호남광역경제권 전기자동차 산업 육성 정책에 대해 소개하고자 한다.

This paper is the result of a research on hybrid tuning technology developed to improve the actual fuel efficiency and reduce emissions of in-use light-duty diesel trucks. In this study, a hybrid powertrain was constructed by inserting an electric motor between the diesel engine and manual transmission of an internal combustion engine vehicle and installing a battery. To verify the safety, a test was conducted based on the Korean tuning regulations. In particular, since there has been no case of tuning an internal combustion engine vehicle into a hybrid vehicle in Korea, it was necessary to carry out all procedures to receive tuning approval. The approval process consists of a technical review, safety verification test, and application for tuning approval. As a result, the test vehicle was approved for tuning because both the technical review and vehicle test results were suitable. Therefore, this study confirmed the safety of diesel hybrid tuning technology, and laid the foundation for the research and development of technologies to tune into an eco-friendly vehicle as well as the activation of related industries.

This research presents a simulation for the fuel economy of parallel diesel hybrid vehicle. Diesel engines compared to gasoline engines have the advantages of higher fuel economy and lower $CO_2$ emission. One of the most ways to meet future fuel economy and emissions regulation is to combine diesel engine technology with a hybrid electric vehicle. The simulation of HEV is growing need for rapid analysis of the many configurations and component options. WAVE, a one-dimensional engine analysis tool, was used to a 2.7L diesel engine. ADVISOR, designed for rapid analysis of the performance and fuel economy of vehicle models, was used to conventional and hybrid electric vehicle by the use of output file from WAVE as the input engine data file for ADVISOR. A parallel diesel HEV is at least $19.7{\sim}36%$ higher fuel economy and improved acceleration ability compared to a conventional diesel vehicle. The energy loss of the parallel diesel HEV is $23{\sim}38%$ less than the conventional vehicle using regeneration.

I am designing a research paper with the aim of studying hybrid vehicles. Hybrid vehicles, as the next-generation automobiles, feature a combination of internal combustion engines and battery engines, resulting in a revolutionary reduction in fuel consumption and harmful gas emissions compared to conventional vehicles. The electric motor in hybrid cars derives power from a high-voltage battery installed within the vehicle, which is recharged during vehicle motion. In contrast to traditional cars, which often experience energy losses due to idling caused by traffic congestion, hybrid systems optimize efficiency by skillfully managing the interplay between the internal combustion engine and the electric motor. This approach effectively addresses the inherent drawbacks of gasoline or diesel engines.Hybrid cars offer an array of benefits, including improved fuel efficiency, environmental friendliness, cost-effectiveness, and reduced noise emission. Consequently, they are progressively becoming a favored alternative among a growing number of individuals. This research endeavor has the potential to contribute towards curbing environmental pollution and dedicating efforts to future automotive research.

Cooled EGR system is an effective method for the reduction of $NO_x$ emission and PM emission from a diesel engine. Proper choice of wavy cooling fins and gas tubes is a key factor of cooled EGR system. As a part of solutions for energy crisis and environmental problems, hybrid vehicles mounted with diesel engines are under development globally. This study investigates the cooled EGR systems for hybrid diesel engine with the specifications of both optimized wavy cooling fins and improved shape of structure to verify the heat exchange efficiency, outlet temperature and gas pressure drop of cooler by means of numerical analyses and rig performance tests. The output of this study will be applied to a 2.0L hybrid diesel engine which is being developed for domestic and overseas market.
