We tested popular wideband O₂ controllers against lab-grade equipment to see how accurate their lambda readings really are under real engine conditions.

Abstract: This study presents an innovative approach to early detection of wire bond lift-off failures in power semiconductor modules (PSMs) using an integrated on-chip temperature sensor. Despite ...
