Description
Technical field
The utility model belongs to many valve distribution mechanisms that middle low power single cylinder reciprocating internal combustion engine is used, and particularly relates to the distribution device that a kind of farm machinery and the universal reciprocating type internal-combustion engine of middle low power of small-sized single cylinder are used.
Background technique
The middle low power single-cylinder engine distribution device of domestic present production, its structure adopt (i.e. an intake valve and an exhaust valve) distribution device of two air gate types usually.The single-cylinder engine distribution device of this class middle low power, owing to have only an intake valve, an exhaust valve, the size of valve is owing to be subjected to the restriction of firing chamber and cylinder bore, the intake and exhaust space that forms is little, scavenging efficiency is low, gas of combustion can not be discharged fully, thereby causes the distribution device of internal-combustion engine to have the following disadvantages at work: 1) less scavenging efficiency makes the lack of air that enters the firing chamber and influences its flammability, thereby influences the output power of internal-combustion engine; 2) because the scavenging efficiency of distribution device is low, and oil consumption is increased, and is less economical, the waste gas after burning discharging not exclusively is easy to generate hazardous compounds such as a large amount of HC, CO and soot, and environment is polluted; 3) distribution device of two air gate types, its valve arrangement make oil sprayer or spark plug offset cylinder cover the center, and the burning starting point can not be in the optimum position, and the piston ring heat load is inhomogeneous, and eccentric wear is serious, reduces the working life of internal-combustion engine easily; 4) distribution device of two air gate types, valve monomer diameter and volume are bigger than normal, and valve rigidity is descended, and heat diffusion area is little relatively, and the heat load of valve increases, the reliability of valve and wearing no resistance.
Summary of the invention
The purpose of this utility model is to provide a kind of compact internal combustion engine general many valve distribution mechanisms at the deficiencies in the prior art, it can effectively increase the free air space and the heat diffusion area of valve, solve that the scavenging efficiency that existing two valve distribution mechanisms exist is low, power and power character is poor, the oil consumption height, reduce the discharging of hazardous compounds such as HC, CO and soot, reduce the heat load of valve, strengthen the reliability and the wear resistance of valve, improve the working life of internal-combustion engine.
The utility model can come to be realized by the following technical programs:
The general many valve distribution mechanisms of compact internal combustion engine, it is made up of parts such as cylinder head 1, exhaust valve 2, intake valve 3, valve spring 4, exhaust valve spring seat 5, exhaust valve rocker arm 6, inlet-valve spring seat 7, inlet valve rocker 8, push rod 9, tappet 10, cam 11, inlet valve seat ring 12, exhaust valve seat insert 13, valve rocker assemblies 14, wherein: exhaust valve rocker arm 6 and the inlet valve rocker 8 common valve rocker assemblies 14 of forming, the valve number is made of the valve more than three at least.It is characterized in that: cam 11 is line with the bottom surface of tappet 10 and contacts, and push rod 9 is connected between the end of valve rocker assembly 14 and tappet 10, and valve rocker assembly 14 is installed in and becomes Lever type on the cylinder head 1 and promote valve motion.When internal combustion engine operation, cam 11 drives tappet 10 up and promotion push rod 9 motions, and push rod 9 drives 14 motions of valve rocker assembly again simultaneously, and the other end of valve rocker assembly 14 drives intake valve 3, exhaust valve 2 motions; When internal-combustion engine is in the aspirating stroke state, inlet valve rocker 8 promotes a plurality of inlet-valve spring seats 7 simultaneously and comes compression valve spring 4, spring seat 7 is opened the inlet air pathway of intake valve 3, this moment, the head conical surface and the inlet valve seat ring on the cylinder head 1 12 of intake valve 3 formed one or more open channels, mixed gas or air dielectric in the passage are inhaled into the firing chamber, and the mixed gas of firing chamber or air dielectric enter the compression stroke of internal-combustion engine; When internal-combustion engine is in the exhaust stroke state, exhaust valve rocker arm 6 drives a plurality of exhaust valve spring seats 5 simultaneously and comes compression valve spring 4, exhaust valve spring seat 5 is opened exhaust valve 2, the valve-face of exhaust valve 2 heads and the exhaust valve seat insert 13 on the cylinder head 1 form another open channel once more, and the waste gas that produces behind the combustion in IC engine is discharged by this passage.
Compared to existing technology, the utlity model has compact structure, advantage such as practical, it can effectively increase the free air space and the heat diffusion area of valve, solve that the scavenging efficiency that existing distribution device exists is low, power and problems such as power character is poor, oil consumption height, reduce the discharging of hazardous compounds such as HC, CO and soot, reduce the heat load of valve, strengthen the reliability and the wear resistance of valve, improve the working life of internal-combustion engine.
