Investigating Engine Performance and Emission Characteristics during Testing of Diesel-Biodiesel Mixed Fuels Obtained from Vegetable Oils and their Modeling by S. R. Mousavi Seyedi, M. Askari, S. M. R. Miri

“…In this study, diesel-biodiesel blends produced from rapeseed, soybean, and palm oil were evaluated for their effects on engine performance metrics, including power (P), torque (T), and specific fuel consumption (SFC). Furthermore, the emissions of pollutants (NOx, HC, CO, and CO₂) from these fuels were measured and modeled using linear and non-linear regression, as well as the adaptive neuro-fuzzy inference system (ANFIS).Materials and MethodsTo leverage the benefits of palm oil biodiesel, known for its high calorific value, along with the low kinematic viscosity of biodiesel derived from soybean and rapeseed oils, pure diesel was blended with 10% and 20% mixtures of rapeseed, soybean, and palm biodiesel, as well as 10% and 20% combinations of all three biodiesels. …”

转矩四分支齿轮传动系统的配齿条件研究 by 相涯, 王三民, 袁茹

“…Torque-splitting transmission can offer smaller size and lighter weight,so it is applied more and more in high-power and high-speed occasions.Compared with single path transmission,structural constraints must be considered in the design because of the existence of virtual constraints in the structure.Besides,the load sharing characteristics of multi-path gear transmission is greatly influenced by different tooth matching schemes.Thus,the research of tooth matching method is very significant to ensure the movement and load sharing behavior of the transmission.For the four-path torque-splitting gear transmission,tooth matching conditions are established and a calculation method is presented in consideration of every path load sharing.A calculation example of a certain power transmission is given,the result shows that tooth matching scheme is obtained by the calculation method can fulfill all matching conditions,and the method has general applicability for other multi-path gear transmissions.…”
