Abstract

This invention discloses engine exhaust gas recirculation device, which includes exhaust manifold, exhaust gas inlet pipe, exhaust gas distributing pipe and intake manifold. The said exhaust gas inlet pipe and exhaust gas distributing pipe are communicated through exhausting gas private channel. The said exhaust gas private channel is set in the water jacket of the engine cover. The external of exhaust gas private channel meets the cooling medium in the water jacket. This invention makes the structure compact and easy fixed. It also increases the working stability of engine cylinder. It is easy to assemble and repair.

Description

technical field [0001] The invention belongs to the technical field of automobile structure, and relates to an automobile engine ventilation system, more specifically, the invention relates to an engine exhaust gas recirculation device. Background technique [0002] Exhaust gas recirculation was barely considered on previous engines. [0003] At present, countries around the world have increasingly stringent regulations on vehicle emissions; the contradiction between energy supply and demand has become increasingly serious. Harsh reality forces car designers, especially engine designers, to pay attention to engine emissions (such as NO X , CO, HC compounds) and the fuel consumption of the engine are more concerned. Various exhaust gas recirculation devices are coming into being, the purpose of which is to fully burn the combustibles in the exhaust gas. These exhaust gas recirculation devices can make a part of the exhaust gas re-mix with the new combustible mixture and en...
