Abstract
The utility model discloses a gasoline engine cylinder body which comprises at least one cylinder, a crankcase body, a plurality of main bearing caps and a plurality of main bearing cap bolts for connecting the main bearing caps and the crankcase body, and a through main oil gallery and an oil hole communicated with a crankshaft hole are arranged inside the cylinder body. The crankshaft hole is machined by using the honing process, the cylindricity and the coaxiality of the crankshaft hole are ensured, friction is reduced, all oil galleries are communicated, the complete lubrication of moving parts is ensured, and thus, the power of an engine is increased and the service life of the engine is prolonged. Multiple cylinders are all machined by using the honing process so as to play the function of oil storage, and the smooth movement of pistons is ensured. The side face is provided with an oil filter installation position used for installing an oil filter, and the oil filter is used for filtering engine oil to ensure that the engine oil is clean; moreover, the side face is provided with an oil scale installation position used for installing an oil scale to measure engine oil quantity, so that sufficient engine oil can be ensured. The utility model has the advantages of simple structure and convenient machining process and is applicable to various gasoline engines.
Description
Technical field
The utility model relates to a kind of petrol engine cylinder body, relates in particular to the cylinder body that is applied on a kind of displacement gasoline engine.
Background technique
Engine cylinder-body is widely used in all kinds of motors, it is the heart of motor, the quality of cylinder body will directly influence the working life of the overall performance and the motor of whole motor, and the position that motor mainly weares and teares is connecting rod, piston etc., freely not cause wearing and tearing mainly due to lubricating.
Summary of the invention
Goal of the invention: technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of lubricated petrol engine cylinder body smoothly is provided.
Technological scheme: in order to overcome the above problems, a kind of petrol engine cylinder body described in the utility model, comprise at least one cylinder, crankcase body, a plurality of main bearing cap, the a plurality of bolt of main bearing caps that connect main bearing cap and crankcase are provided with main oil gallery that runs through and the oilhole that runs through with crankshaft hole in cylinder interior;
Described crankcase body material is a grey cast iron;
Described main bearing cap material is a powder metallurgy;
The bolt of main bearing cap grade is 12.9 grades.
Described main bearing cap is finally turned round with the power of 45 ± 3N.M by bolt of main bearing cap and is combined back processing with crankcase.
Beneficial effect: a kind of petrol engine cylinder body crankshaft hole that the utility model provides adopts honing technique processing, the cylindricity and the coaxality of crankshaft hole have been guaranteed, reduce friction, run through between each oil duct, the assurance moving element is lubricated to put in place, the working life that helps improving engine power and prolong motor; A plurality of cylinders all adopt honing processing, play the oil storage effect, guarantee that the piston operation is smooth and easy; Organic oil filter cleaner installation position, side can be used for the fitting machine oil rectifier, is used for filtering machine oil, guarantees the machine oil cleaning; And organic oil scale installation position, being used for the fitting machine oil scale comes the measuring machine oil mass, guarantees the machine oil abundance.
