Abstract
The present disclosure prevents foreign matter such as particles composed of soot and hydrocarbons from entering an EGR passage. Thus, a foreign matter intrusion prevention structure includes: an internal-combustion engine; an intake manifold that introduces outside air into a cylinder of the internal-combustion engine; an exhaust manifold that collects exhaust gas discharged from the cylinder of the internal-combustion engine; an exhaust gas purifying device that is connected to the exhaust manifold through an exhaust duct; an exhaust gas recirculation device that sends a part of the exhaust gas from the exhaust manifold to the intake manifold without passing the part of the exhaust gas through the exhaust gas purifying device; and an intrusion prevention net provided in a vicinity of an inlet from the exhaust manifold to the exhaust gas recirculation device.
