Description

汽车排气管 Car exhaust pipe

本实用新型涉及一种汽车排气管,特别是涉及一种利用外界高速空气吸引,使主排气管内的废气冲淡,并加速废气的排除,而降低引擎温度及积垢的汽车排气管。 The present invention relates to an automobile exhaust pipe, particularly to a high speed by using ambient air suction, dilute the exhaust gas in the main exhaust pipe and accelerate the exhaust gas exclusion, and the engine temperature decreases fouling of automotive exhaust pipe.

燃料在引擎内燃烧时,因混合气燃烧后的温度将超过4000°F,会产生非常巨大的热量,这些热量需要藉由排气管排出,因温度过高,会使引擎的机件如活塞、活塞环、进排气阀门、汽缸壁等原本润滑机件的机油遭受破坏,导致引擎不能得到正常的润滑效果,所以排气系统于车辆的动力系统中,占有非常重要的份量。 When the fuel is burned in the engine, because the temperature of the mixed combustion gas to more than 4000 ° F, will have a very great heat, which is required to be discharged by the exhaust pipe, due to high temperature, engine parts such as a piston will , oil lubricated parts of the original piston rings, intake and exhaust valves, cylinder walls and other damage suffered, resulting in engine lubricating effect can not be normal, so the exhaust system to the power system of the vehicle, plays a very important weight. 燃料燃烧的废气经由排气岐管排出,排气岐管依引擎型式不同,可栓固在汽缸或汽缸体上,岐管的弯度必须和缓,不可有反压力产生,废气从岐管流向消声器时,会产生一个气阻,然后经尾管排出,其间并没有加速废气排放的动力,废气无法加速排出,所以经常积在排气管内,造成排气管积碳情形严重而阻碍废气的排出,而导致引擎温度过高。 Fuel combustion exhaust gas through an exhaust manifold discharge, an exhaust manifold according to different engine types, may be bolted to the cylinder or the cylinder block, camber manifold must be gentle, not with a back pressure is generated, the exhaust gas from the manifold flow muffler , an air resistance is generated, and then discharged through the tail pipe, and during which no driving force to accelerate emission of exhaust gas discharged not accelerate, so often accumulated in the exhaust pipe, the exhaust pipe resulting in a serious situation carbon impede exhaust emissions, and cause the engine temperature is too high.

本实用新型的目的在提供一种汽车排气管,在废气排出时,可吸引外界空气充分混合,不但可冲淡废气、降低引擎温度,且可防止排气管内积垢的产生。 Object of the present invention to provide a vehicle exhaust pipe, the exhaust gas is discharged, outside air can be sufficiently mixed suction, not only dilute the exhaust gas, the engine temperature is lowered, and preventing the fouling generated in the exhaust pipe.

本实用新型的特征在于:该汽车排气管包括一个具有前后段粗细不一的多孔管及一个套接在多孔管外部的外管,在该多孔管前、后段分别利用进、出气孔环与外管两端固接,使外界空气经由进气孔环上的穿孔进入外管内部,且吸引多孔管内的废气充分地混合,然后进入多孔管较小管径的区域内,使外界空气具有较大的空间可以吸收多孔管内部的废气,并产生消音作用,被冲淡后的废气由出气孔环的穿孔及外管环周上的环孔结构加速地排出管外,达到排除废气,加速排气的目的。 The present invention is characterized in that: the motor vehicle exhaust pipe comprising a front section having a varying thickness of the outer perforated tube and the outer porous tube in a tube socket, before the porous tube, respectively, using the rear stage inlet, vent ring both ends of the outer tube is fixed to the outside air via the perforations into the interior of the outer tube into the ring hole, and the exhaust gas suction within the porous tube sufficiently mixed, and then into the porous region of smaller diameter of the tube, so that outside air having the exhaust gas can absorb a large space inside the porous pipe and silencer effect is generated, the exhaust gas is diluted by the pore structure of the perforations and the ring on the outer periphery of pipe ring accelerated discharge hole ring outer tube, to exclude the exhaust gas, exhaust acceleration the purpose of the gas. 而且,该多孔管前端形成扩大部,当汽车行驶时,可使大量外界空气顺利地进入管内,且尾端的管径缩小,使空气与废气快速地混合,并压缩加速排出外部,外管两端各设有环孔结构,有助于外界空气进入、排出,以减少废气的效果。 Further, the porous tube distal enlarged portion is formed, when the cars, a large number of outside air can smoothly enter the inner tube, and the reduced diameter trailing end of the air mixing with the exhaust gas quickly and accelerate the discharge of the compressed outer ends of the outer tube each hole is provided with a ring structure, contributes to outside air into the discharge, in order to reduce the effect of exhaust gas.
