Lean NOx traps are being extensively examined (Ref. 1-12) because they can be efficiently used to reduce the NOx emissions from port fuel injected and direct fuel injected spark ignited gasoline ...
For removing NO x from lean burn engine exhausts, lean NO x trap (LNT) or NO x storage and reduction (NSR) catalysts are considered as one of the technologies which has the most potential. In the NSR ...
Five key principles of lean: value, value stream, flow, pull, and perfection, can be applied to any business process that contains wasteful steps, in any industry.
Lean manufacturing has been around for decades. The implementation of lean tools and techniques usually results in impressive gains in efficiency and production. These eight real-life examples show how lean methods improve operational performance and reduce costs.
Lean seeks to improve manufacturing operations via Takt Time, Standardized Work, Continuous Flow, Poka-Yoke, Value Stream Mapping, Kaizen, and Six Big Losses.
P rofessionals who follow Lean Six Sigma use the data-driven methodology to improve processes by eliminating defects, variations, and waste. They embrace the disciplined, data-driven approach using problem-solving tools, statistical methods, and advanced analytics. The Six Sigma belt levels and certifications are similar to those of martial arts.
DETROIT --General Motors is leaning toward a controversial emissions system, urea injection, that enables diesel engines to meet tough pollution standards in place for 2009. The technology, also known ...
The software used by Volkswagen to get around environmental standards in some 11 million vehicles effectively told each car to go into a “clean mode” when it detected the car was being tested for ...
