Critical Topics in Exhaust Gas Aftertreatment: No. 3 (Mechanical Engineering Research Studies, Engineering Design S.)

Very good book about emissions and catalysts. You need to be a professional of the field or a researcher to be able to use and understand this book. A reference despite its age. Its explanation of the in catalyst chemistry and the substrates is very handy as well as the part related to the lambda sensor and how the different gases affect it's reading. If you are a mechanic (not an engineer) or a journalists who dares to write about emissions, don't buy this book.
