Catalytic converters are pivotal components in vehicular exhaust systems, tasked with reducing harmful emissions to meet stringent environmental regulations. This paper offers an in-depth examination of the latest advancements and prospective trajectories for augmenting the efficiency of automotive catalytic converters. Through a survey of contemporary research and industry practices, we explore novel catalyst formulations, innovative design methodologies, and operational strategies aimed at bolstering conversion efficiency and curbing emissions of pollutants like nitrogen oxides (NOx), carbon monoxide (CO), and hydrocarbons (HC). Additionally, we scrutinize emerging technologies, including nanostructured catalysts and catalytic coatings, alongside advanced exhaust gas treatment systems, all poised to revolutionize catalytic converter performance. Furthermore, we address key challenges in efficiency optimization, such as catalyst durability, thermal management, and regulatory compliance, underscoring the need for comprehensive solutions. By synthesizing these insights, our paper not only encapsulates the current state-of-the-art in catalytic converter technology but also charts a course for future research endeavors, aiming for ever more efficient and environmentally sustainable automotive emissions control.

To solve the problem of springback in traditional multi-point forming (MPF), a new multi-point forming process, namely, multi-point forming with individually controlled force-displacement (MPF-ICFD), was proposed. The core idea of this process is to simultaneously apply a normal force to the upper and lower sides of a sheet during the whole forming process. Therefore, the deformation sequence of the sheet metal is changed from local constraint overall deformation in the traditional MPF process to global constraint local deformation in the MPF-ICFD process, which is beneficial for improving the deformation uniformity and reducing the sheet springback.In this work, the deformation characteristics and forming force limits of MPF-ICFD were studied through mechanical analyses, numerical simulations and experiments. The results show that, compared with the traditional MPF, the springback of sheet metal is 2 significantly reduced, and the uniformities of the strain and wall thickness are significantly improved in the MPF-ICFD. The influence of the sheet thickness on the upper limit of the forming force is more significant than that on the lower limit. For an aluminium alloy sheet with a wall thickness of 1.5-3 mm, the upper and lower limits of forming force of a single head change linearly from 6.3 kN to 12.6 kN and from 0.5 kN to 1 kN, respectively.
