Description
Technical field
The invention belongs to internal combustion engine with integrated cylinder block cylinder head technical field, more particularly, to a kind of integrated cylinder
Body structure.
Background technology
Internal combustion engine is used for for energy in fuel being converted into the available Effective power of the mankind as thermal technology's conversion equipment, in fossil
The increasingly deficient big Modern Internal-Combustion Engine of fuel constantly pursues high reliability, economy high, is using cylinder combustion pressure is improved
One of method of the effective heat energy transformation efficiency of internal combustion engine is improved, maximum combustion pressure has reached 22MPa in current IC engine cylinder
More than, gas in-cylinder combustion temperature bears very big mechanical load also above 1800 DEG C during combustion in IC engine acting
And thermic load.Therefore it is required that the whole machine cylinder block of internal combustion engine is stamped more preferable entirety stiffness to resist in cylinder of internal-combustion engine with cylinder
Burning explosion pressure and thermic load.
Body of the internal-combustion engine structure generally includes four sections of cylinder head, cylinder block, upper crankcase and lower crankcase, in modern ic
Need to consider from many-sides such as overall structure rigidity, compactedness and anufacturabilities in machine design process, most of cylinders
It is individual components to cover, cylinder block and upper crankcase integrator, and lower crankcase turns into a fuel reserve tank.Cylinder block and cylinder head it
Between with cylinder head gasket seal, have in cylinder block meet the movement parts such as I. C. engine crankshaft, piston, connecting rod mechanism it is reciprocating with
Realize that working medium thermal technology changes.
The effect of combustion engine cylinder head is sealing cylinder, and combustion chamber, Integrated design in cylinder head are constituted with piston top instrument
The structure such as inlet and exhaust valve and its air flue, spark plug, mounting hole of oil sprayer.Cylinder head is connected with cylinder block using cylinder head bolt
Connect, while generating high-temperature high-pressure fuel gas leakage in preventing internal combustion engine working medium combustion process, it is necessary between cylinder head and cylinder block
Sealed using Cylinder head gasket.
During internal combustion engine operation, cylinder block bears very complicated load with cylinder head, and such as each gas in the jar is to cylinder head
Bottom surface and the uniform atmospheric pressure of cylinder surface, in the side force of each cylinder wall, bent axle loads the power of each base bearing, branch to piston effect
Frame is to reaction of bearing of internal combustion engine etc..The size of these power, direction are continually changing with operating mode and crank angle, some points of force application
Also it is being continually changing.Additionally, when even if internal combustion engine is inoperative, each cylinder head bolt, Main bearing bolt pretightning force it is also very big,
Appropriate section is set to produce very big stress and deformation.Therefore, must assure that during cylinder block with Cylinder head design sufficiently strong
Degree and rigidity, neither crack the damage with other forms, also occur without excessive deformation.
Internal combustion engine cylinder block and cylinder head are split-type structural, general internal combustion engine using cylinder head bolt by cylinder block with
Cylinder cap and head gasket are attached, and structure design parts are more, particularly in multi-cylinder engine design process, for every
One cylinder is required for walking some cylinder head bolts and is fastened Gao Ran for being produced in resistance internal combustion engine working process
Burn pressure.There is head gasket with cylinder head medium design with lubrication, IC engine cylinder block to be winding is effectively cooled internal combustion engine simultaneously,
Head gasket effect on the one hand in ensureing IC engine cylinder combustion process combustion gas occur without leakage, another front cover head gasket is by internal combustion
Machine cylinder block inside water cavity, lubricant reservoir and cylinder head water cavity, lubricant reservoir are attached, and connected mode generally utilizes cylinder head
The thrust of bolt is realized, but in actual application, head gasket occurs gas leakage in the case where high-temperature high-pressure work environment is born
Oil leakage phenomenon, so as to reduce internal combustion engine complete machine power output and operational reliability.Its number of components is more and due to being split type
Attachment structure, durable in order to ensure the major part reliable operation such as piston, connecting rod, bent axle, cylinder jacket, they must keep accurate
Position, therefore it is required that design level that will be higher, level of processing and mounting technology level, so that also increasing combustion engine is manufactured into
This.
The content of the invention
In view of this, the present invention is directed to propose a kind of integrated block structure, is burnt with improving traditional combustion engine resistance
Pressure capability, solves the problems, such as head gasket gas leakage and cylinder head bolt structure difficult arrangement.
To reach above-mentioned purpose, the technical proposal of the invention is realized in this way:
A kind of integrated block structure, including body;
A combustion chamber is provided with the middle part of the body, the combustion chamber is a seamless cavity;
Piston is provided with the combustion chamber, the piston is slidingly sealed cooperation with the sidewall of combustion chamber.
