Abstract
The utility model relates to a gas engine with a cylinder diameter of 102mm, which comprises a cylinder, wherein a piston is arranged in the cylinder; the piston is provided with a plurality of piston rings; the piston is connected with a small end of a connecting rod by a piston pin; a large end of the connecting rod is connected on a shaft neck of a crankshaft; the inner diameter of the cylinder is 102mm; and the piston stroke is 120mm. The parameters are obtained by reasonable calculation and test, thus, the unit power meets the design requirement and the efficiency of the gas engine is greatly improved. The gas engine has low gas consumption and good stability and is economic and practical. Moreover, the gas engine can use the gas with low methane concentration, has wide range of the used gas, can use various gas, such as natural gas, marsh gas, landfill gas, oil field gas, gasification gas and the like, and various renewable energy resources, is very environment-friendly due to use of the gas and has good economic benefit due to utilization of the renewable energy resources.
Description
Technical field
The utility model relates to technical field of internal combustion engines, relates in particular to the gas engine of a kind of cylinder diameter 102mm.
Background technique
Internal-combustion engine is with its hot efficiency gas height, compact structure, mobility strong, and the easy advantage of operation maintenance is world-famous for.100 for many years, and the huge vitality of internal-combustion engine is lasting.At present the owning amount of internal-combustion engine has substantially exceeded any other heat engine in the world, occupies considerable status in national economy.Modern Internal-Combustion Engine becomes current consumption maximum, purposes is the widest, none is equal to it most important thermo-mechanical machine especially.
The world today is faced with energy shortage and environmental protection two hang-ups, and domestic garbage, liquid gas, acetylene etc. produce a large amount of harmful gases in combustion process, cause the severe contamination to environment.How to address these problems one important topic that has become industry; At above-mentioned situation, gas engine has appearred in industry, and the many performances of gas engine are all superior more than petrol engine and diesel engine.Petrol engine and diesel engine complex structure, the thermal efficiency lower (petrol engine 21-30%, diesel engine 28-40%), waste great amount of fuel oil.And the oil reserves are limited, and to making fuel oil more and more nervous, it is imperative to save fuel oil.Yet existing gas engine generally exists efficient low, the gas consumption height, and shortcoming such as stability is bad, and existing gas engine can not use the combustion gas of low methane, and its application area is little.Therefore, it is high to invent a kind of efficiency gas. and it is extremely urgent to be easy to the gas engine promoted the use of again.
Summary of the invention
It is low that the technical problems to be solved in the utility model provides a kind of gas consumption, efficiency gas height, the gas engine of the cylinder diameter 102mm of good stability.The utility model is achieved through the following technical solutions:
The gas engine of a kind of cylinder diameter 102mm of the present utility model comprises cylinder, is provided with piston in the cylinder, piston is provided with some roads piston ring, and piston connects the small end of a connecting rod through wrist pin, and connecting rod tip is connected on the axle journal of a bent axle, described cylinder bore is 102mm, and piston stroke is 120mm.
As preferably, described piston head caves inward and forms the firing chamber.
As preferably, described gas engine is set to 4 cylinders, and its discharge capacity is 3.92L.
As preferably, described gas engine is set to 6 cylinders, and its discharge capacity is 5.88L.
The gas engine of cylinder diameter 102mm of the present utility model, because cylinder diameter and stroke are to research and develop design voluntarily, numerical value is 102mmx120mm, draws through reasonably calculating and testing, its volume is little, can not take too many space, and make the power of the assembling unit reach designing requirement, improve the efficient of gas engine greatly, efficient can reach 28-42%, gas consumption is low, and good stability is economical and practical; In addition, this kind combustion gas function is used the combustion gas of low methane, and employed combustion gas scope is wide; the various combustion gas and the various renewable sources of energy such as natural gas, biogas, rubbish landfill gas, oil field gas, gasification gas be can use, combustion gas, very environmental protection used; and utilize the renewable sources of energy, good in economic efficiency.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is the schematic representation that the gas engine piston of the utility model cylinder diameter 102mm is positioned at lower dead center;
