According to foreign media reports, a team from CMT thermal Institute of upv University in Spain has proposed a new architecture, which aims to achieve more efficient and less pollution, combining the advantages of electric motors with dual fuel combustion technology. The first research results of the researchers have confirmed that the technology can meet the pollution and carbon dioxide emission limits of the future transportation sector, and also attracted the interest of companies such as group truck technology (France) that make cars for road traffic, as well as oil companies such as Arab oil (France). The main novelty of upv researchers' proposal is that the thermal part of the hybrid engine has dual fuel assemblies. Antonio Garc í a, a researcher of CMT thermal engine, said: "at present, there are engines with dual fuel structure, including natural gas and diesel. Although there are also hybrid engines, there is no engine that can combine the two technologies." In this study, Garc í a said that the simulation experiment shows that the dual fuel combustion technology can reduce the NOx emission by about 30%. Compared with the diesel engine, there is little soot and the efficiency of the engine is not affected. In addition, compared with traditional diesel vehicles, the use of dual fuel technology in non vehicle can reduce gasoline consumption by 25%, because the technology can optimize the use area of dual fuel internal combustion engine. "By increasing the electrification of the power plant engine plug-in hybrid, combined with these two technologies, nitrogen oxide emissions can be reduced by 70% and carbon dioxide emissions in the exhaust pipe can be reduced to 50 k/km, far less than the 95 g/km required by the anti pollution act of 2021, compared with diesel engines," Garc í a said Javier monsalve, assistant professor and researcher of CMT thermal engine research institute, said that the combination of internal combustion engine and electric motor increased the "degree of freedom", which must be studied in depth in order to optimize vehicle functions. One of the main results of this study is to get a reliable method, through computer simulation, to choose the best design of hybrid vehicles, combine it with dual fuel combustion system, and consider the operating conditions. Upv's CMT thermal engine team explained that in order to compare the actual benefits of different transport solutions, the impact of each technology must be analyzed from a global perspective. The life cycle analysis of the technology is one of the most commonly used tools for researchers and institutions responsible for formulating anti pollution policies, and it may be implemented in future legislation. Santiago Mart í Nez, a researcher in the CMT-Thermal engine research group, said: "our approach distinguishes between the front end system (mass production, use phase and end of vehicle life treatment phase) and the back end system (materials, resources, electricity, infrastructure and generated waste), enabling identification of major pollution components as well as possible areas for improvement."
