Embodiment Construction

[0029] Such as Figure 1-4 As shown, the present invention is a high-efficiency internal combustion engine intake and exhaust system, including a camshaft assembly, an air filter assembly, and a muffler assembly. When the valve is closed, it is 10-38° after the bottom dead center, when the exhaust valve is opened, it is 25-45° before the bottom dead center, and when the exhaust valve is closed, it is 2-10° after the top dead center.

[0030] A high-efficiency internal combustion engine intake and exhaust system, the cam 33 of the valve train is an eccentric cam 33 . Cam 33 open line 35, close line 36, depth line 37 are straight line or arc.

[0031] The filter element 28 of the air filter 5 is provided with a folding groove 29 which forms an angle β with the axis. The air filter 5 is provided with a heat insulating layer 30 or made of a heat insulating material 30 on the air intake pipe 27 or the air intake pipe pad 30 or the casing 26 . The upper side of the casing 26 is p...

Abstract

The invention discloses a high-efficient intake and exhaust system of an internal combustion engine, wherein a cam of a gas distribution mechanism is an eccentric cam, and a profile of the eccentric cam consists of a base line, an opening profile, a closed profile and a deep-stroke line. The high-efficient intake and exhaust system disclosed by the invention has the advantages of suitability for large, intermediate and small cylinders, a single cylinder and multiple cylinders, a water-air-cooled engine, increased power due to natural air suction (preferably boosted intermediate cold) and full combustion, low oil consumption, low exhaust reaching the Europe emission standard 1-4, low noise, low vibration, low idle speed, low cost, long service life, good startability and reliability, and reduced oil consumption and emission compared with the same model of the internal combustion engine, and is an upgrade product that the energy is saved by 20 percent and the emission is reduced by 50 percent; and the internal combustion engine with performances exceeding the advanced level of the world and various matched powers are obtained.

Description

[0001] This divisional application is: application number: 200410087853.X, title of invention: high-efficiency internal combustion engine and its combustion method, application date: August 21, 2004. technical field [0002] The invention relates to a high-efficiency internal combustion engine combustion system, in particular to a high-efficiency internal combustion engine gas distribution mechanism. Background technique [0003] At present, the overall proportioning and valve mechanism of the internal combustion engine are not reasonable, and the combustion is not complete, so that the fuel consumption is high, the emission is high, and it is difficult to start. Contents of the invention [0004] The object of the present invention is to provide a high-efficiency internal combustion engine intake and discharge system in order to solve the above-mentioned defects of the prior art. [0005] The purpose of the present invention is achieved through the following technical sol...
