Secondary air supplying apparatus for internal combustion engine and air heating apparatus thereof |
摘要 |
A secondary air supplying apparatus for an internal combustion engine and a gas heating apparatus are provided to enable high-performance exhaust gas purification in a catalytic apparatus of the internal combustion engine, in particular, even at a low-temperature starting time. A secondary air supplying apparatus supplies secondary air to the catalytic apparatus through a secondary air introducing path for communicating the intake side of the internal combustion engine with an exhaust manifold. In the apparatus, a gas heating apparatus having an exothermic body is provided for the secondary air introducing path.
