“Secondary Air Injection with E-Boosting Devices”
Future emission norms will focus on reducing cold start emissions of gasoline engines. One promising solution is to use secondary air injection (SAI). However, current SAI systems are not powerful enough to operate against high exhaust back pressure.
Read this paper, you will learn about how Electric boosting products, such as E-Compressors and E-Turbos, can overcome this limitation. These products can provide SAI for cold start emissions, while also improving engine efficiency and reducing emissions under normal operation.

“Development of Low Nickel Austenitic Stainless Steel for High Temperature Gasoline Turbochargers”
A new low-nickel austenitic stainless steel has been developed for use in turbine housings of turbochargers for gasoline applications.
Download this paper, and you will learn more about the new steel, which is made with nitrogen that acts as a strong austenitic stabilizer and reduces the need for nickel. This makes the new steel more cost-effective than traditional high-nickel stainless steel. The new steel was developed using an integrated computational materials engineering (ICME) methodology, which combines computational and experimental techniques. It has been tested up to 1050°C gas temperature under severe thermal shock loading conditions and compared with existing high-nickel conventional steels. The results show that the new steel is a promising alternative solution providing both better performance and lower cost for high temperature turbocharger applications.
