New Engine Technology Breathes New Life into Old Designs2010-11-29 Author: Peter F. Meier From: Motor Age It takes energy to compress an air/fuel charge, spin the individual piston through its four strokes and overcome the friction inherent in all the moving parts. This is negative energy, or the amount of energy it takes to produce the mechanical work needed in the combustion process. The energy releas Hyperlink to Original Source
Catalytic Converters not Always the Problem with Catalyst Efficiency2010-11-29 Author: Peter F. Meier From: Motor Age The catalytic converter is the emissions system's last chance to clean up exhaust gases before they reach the atmosphere. It does so by storing excess oxygen during times of lean combustion mixtures and releasing oxygen during rich mixtures, oxidizing the combustion gases and converting them to gase Hyperlink to Original Source
