Honda’s latest technology uses ammonia generated directly within the catalytic converter. It features a two-layer structure: one layer adsorbs NOx from the exhaust gas which, during periodic ...

So the key to complying with the new standards is cleaning up cold-start ... its operating temperature quickly, Honda crimps the converter directly onto the exhaust manifold, which is made of ...

In Honda's new clean-diesel application ... the injection time was reduced by a new 29,000-psi common-rail system, and the exhaust gas recirculation (EGR) system efficiency was improved.
