The article discusses the influence of heat treatment and metal forming parameters on formability and the structure of the AZ91 cast magnesium alloy. The aim of the article is to determine the optimal parameters of homogenization and plastic deformation of sand castings made of the AZ91 alloy in order to improve their properties and structure. In this study, sand castings made from the AZ91 alloy...
This article provides an overview of the materials used to manufacture magnesium wheels for light vehicles. The analysis was conducted with the aim of developing a new, efficient technology for molding magnesium alloy wheels for light vehicles from preforms cast into metal molds. The knowledge accumulated so far on materials and their properties for the production of magnesium wheels will allow the...
The article presented analyses the impact of damage to the injection system on the emission of toxic subsumes in a spark-ignition internal combustion engine. The work focuses on the basic elements of the injection system, which include injectors, throttle position sensor, coolant temperature sensor and lambda sensor. In addition, a catalytic reactor has been included in the context of its direct cooperation...
The article discusses the impact of ignition system damage on the emission of toxic subcategories in a spark-ignition internal combustion engine. The aim of the work was to develop an analytical model of ignition system diagnostics, test performance and comparative analysis of the results of simulations and experiments. The model developed allows to analyse the basic parameters of the ignition system...
