Air intake-exhaust integrated machine

Abstract

The invention discloses an air intake-exhaust integrated machine of a four-stroke internal combustion engine. The air intake-exhaust integrated machine mainly comprises an exhaust pipe, an exhaust funnel and an air-filtering funnel which are arranged in layers, wherein the innermost exhaust funnel is provided with anechoic holes, a steel strainer is arranged between the exhaust funnel and the air-filtering funnel; the top of the exhaust funnel is provided with a thread, a nut air-filtering cover is screwed on the thread, the steel strainer can be taken out for cleaning after the nut air-filtering cover is screwed out; and the branches of the exhaust pipe and air intake pipe are separately connected on the exhaust port and air intake of the cylinder end of the internal combustion engine. When using the invention, the exhaust heat on the funnel wall of the exhaust funnel is utilized to preheat the inlet gas, the preheated gas enters in the cylinder to be compressed and burned, then ultra-high-temperature gas can be generated and finally fuel is injected to light the gas to obtain super power. Therefore, the fuel can be fully and completely burned, the efficiency can be greatly increased and the discharge amount of poisonous or harmful exhaust gas can be significantly reduced.

Description

technical field [0001] The present invention is a technology that combines intake air filtration and exhaust muffler of a four-stroke internal combustion engine. Background technique [0002] The four-stroke internal combustion engine we are familiar with is that the intake air filter is completed by the filter, and the exhaust muffler is completed by the exhaust pipe. This kind of exhaust cylinder is separated from the filter so that the waste heat of the exhaust cylinder is not well utilized, and the temperature of the intake air in the filter is not too high after entering the cylinder due to its low temperature, resulting in incomplete combustion of the oil-air mixture. The efficiency is low, and the amount of toxic and harmful exhaust gas is large. Contents of the invention [0003] The invention provides a simple and practical air intake and exhaust integrated device, which is a technology of preheating the intake air in advance, a technology of high efficiency, ene...
