According to foreign media reports, a team at the CMT-Thermal Research Institute of UPV University in Spain proposed a new architecture that is working to achieve a more efficient and less polluting engine, combining the advantages of hybrid electric motors with dual Combining 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 caused companies such as Volvo Group Truck Technology (France) to make cars for road traffic, as well as the Arab National Petroleum (France) ) Waiting for the interest of oil companies.
At the same time reduce emissions of nitrogen oxides, soot and carbon dioxide
UPV researchers suggested that the main novelty of this solution is the thermal part of the hybrid engine, which has dual fuel assemblies. Antonio GarcÃa, a CMT-Thermal engine researcher, said: "At present, engines with dual fuel structure include natural gas and diesel. Although there are hybrid engines, there is no engine that can combine these two technologies."
In this study, GarcÃa stated that the simulation experiments conducted show that the dual-fuel combustion technology can reduce nitrogen oxide emissions by about 30%. Compared with diesel engines, 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-plug-in hybrid vehicles can reduce gasoline usage by 25% because the technology can optimize the area of ​​dual-fuel internal combustion engines.
GarcÃa said: "By increasing the electrification of power plant-engine-plug-in hybrid vehicles, the combination of these two technologies can reduce nitrogen oxide emissions by 70% and carbon dioxide emissions in the exhaust pipe compared to diesel engines. Reduced to 50 k / km, which is far below the 95 g / km emissions required by the Anti-Pollution Law of 2021. "
New methods for optimizing engines
Javier Monsalve, an assistant professor and researcher at the CMT-Thermal Engine Research Institute, said that the combination of internal combustion engine and electric motor increases the "degree of freedom", and in order to optimize the function of the vehicle, this degree of freedom must be studied in depth. One of the main results of this study was to obtain a reliable method to select the best hybrid vehicle design through computer simulation, combine it with a dual-fuel combustion system, and take into account operating conditions.
Assess its impact based on analysis of the technology life cycle
UPV's CMT-Thermal engine team explained that in order to compare the actual benefits of different transportation solutions, the impact of each technology must be analyzed from a global perspective. The analysis of the life cycle of this technology is one of the most commonly used tools for researchers and institutions responsible for formulating anti-pollution policies, and may be implemented in future legislation.
Santiago MartÃnez, a researcher at the CMT-Thermal engine research group, said: "Our approach distinguishes between front-end systems (mass production, use phases and end-of-life processing phases) and back-end systems (materials, resources, electricity, infrastructure and generated waste) it is possible to identify the major components as well as contamination of the art could be improved.
