Environmental pollution from transportation means and natural resource degradation are the top concern globally. According to statistics, NOx PM emissions vehicles account for 70% of total in urban areas. Therefore, finding solutions reduce is necessary. Changing engine's internal combustion method considered promising influential among known solutions. One research directions a engine using Premixed Charge Compression Ignition (PCCI) combined with biofuels improve mixture formation process, reducing emissions. this study presents mechanism traditional low-temperature process engines. Besides, theoretical basis flame spread during also introduced. The key feature that it has modeled diesel engines under PCCI modes. This was accomplished blends waste cooking oil (WCO)-based biodiesel fuel, as well ANSYS Fluent software. results showed B20 fuel can significantly emissions, although HC CO tend increase, thermal efficiency tends decrease. In further studies, different modes should be thoroughly examined so implemented practice pollutant

ABSTRACT Aiming at the problems of poor reliability and low visualization in monitoring power metrology laboratories, a smart laboratory environmental recognition method based on digital twins improved Transformer is proposed. Firstly, architecture designed twin technology, achieving comprehensive perception through interaction between physical entities virtual platforms. Then, large kernel block module added to Swin model enhance representation ability cross—modal feature information, deployed intelligent layer architecture. Finally, used analyse multi‐source information fused for decision‐making obtain reliable identification results personnel behaviour device status. Experimental analysis this scenario shows that can effectively identify various behaviours personnel. The accuracy sleeping reaches 96.74%, average status 91.74%. Meanwhile, study also points out limitations current system detecting some failure modes, providing more theoretical technical references construction laboratories.

Abstract Using modern high-performance microcontrollers with wireless interfaces, built-in ADCs and low overall consumption, we develop a portable, real-time parametric diagnostic system for marine engines. The is based on the use of Android/iOS gadgets that receive information from sensors via Bluetooth then carry out necessary calculations display charts data in real time. developed here uses combination gas pressure sensor working cylinder vibroacoustic sensor, which expands capabilities diesel engines under operating conditions. This solution allows diagnosis fuel injection system, valve train mechanism, several other engine systems. In order to portable engines, it first solve problem analytically determining top dead centre (TDC), since such does not special this. An algorithm TDC proposed here, an analysis measured diagram rather than its derivative, minimises influence digital analogue noise. Our subsequent synchronisation applicable absence about actual compression ratio cylinder, typical scenario variable timing. also works conditions only approximate charge air pressure, are refined during iteration process. A formula initial position. Parameters irregular operation considered, can be calculated time using diagrams vibration. Methods expressly assessing stability functioning main systems by monitoring analysing number successive cycles considered. To assess unevenness engine, dispersion estimate deviations parameters used. enable comprehensive assessment time, CII (cycle irregularity index) criterion developed. processing methods described this article provide accurate indicated power, due precise determination TDC, thereby enabling cycles, optimal tuning systems, results operation.
