Description
Technical field
The present invention relates to engine technology, relate in particular to a kind of motor vehicular engine.
Background technique
Along with the variation of domestic and international Motorcycle Market demand, people have compared tangible difference to the motorcycle engine performance requirement with traditional type, particularly to motor style, output torque, power, oil consumption, vibrations, environmental protection etc.At present; Motorcycle engine on the market can be divided into following two kinds according to the gas distribution structure characteristics: first kind is underlying cam post rod type motorcycle engine, and promptly the CG motorcycle engine of the ripe title of industry is a kind of early stage motorcycle engine structure; Account for the market significant proportion; Its main advantage is that product yield is big, and the components supplying chain is sufficient, and as a very ripe type; Its gear has reliable stability, but this engine power performance is poor, noise big, vibration is big, oil consumption is high; Second kind is overhead cam chain type motorcycle engine; Be the CB motorcycle engine of the ripe title of industry, its advantage be noise little, simple in structure, bigger room for promotion is arranged, but performances such as power, moment of torsion significantly do not improve; Vibrations and oil consumption do not reduce yet; And owing to the lubricated and radiation system that is contained in the distribution component such as cam on the cylinder head is insufficient, cause this type underpower, often have cam wear and valve rocker to burn phenomenon to death and take place.Therefore, to above aspect, need reasonably innovate existing technology.
Summary of the invention
To above defective, the present invention provides a kind of and helps promoting performance, can reduce vibrations, increases the service life, practices thrift cost, the motor vehicular engine of product emission compliance, to solve many deficiencies of existing technology.
For realizing above-mentioned purpose, the present invention adopts following technological scheme:
A kind of motor vehicular engine comprises oil pump, oil filtration unit, cylinder block, gear, and said oil pump is arranged at the right crankcase cover internal chamber and its top is provided with the oil filtration unit, and this right crankcase cover is wrapped in the right crankcase periphery; Cylinder block is installed at the top of whole crankcase and cylinder head is equipped with in this cylinder block upper end, and the cylinder head top is provided with valve rocker; Simultaneously; The motor opposite side relative with right crankcase is provided with left crankcase and this crankcase outer installment has the left crankcase lid; Be arranged in left crankcase lid internal chamber a magnetogenerator is installed; Between the indoor crank-connecting rod that is provided with of engine cavity between left crankcase and right crankcase, this crank-connecting rod and left crankcase drive sprocket is housed and this drive sprocket is connected driven sprocket through chain; In addition, said cylinder block is externally connected to Carburetor.
Said drive sprocket rear side connects gear and this gear both sides are respectively equipped with clutch, starting shaft assembly, and acclivitous spark plug is set in the said cylinder head.
The beneficial effect of motor vehicular engine of the present invention is:
(1) through increasing power, moment of torsion, on the basis of former organic type, increase the power of 0.3-0.5KW, moment of torsion increases 0.8-1.5Nm; Improve left and right crankcase structure, utilize the motor dynamic balance principle, reduce bent axle in movement process,, improve the engine operation environment, reduce vibrations because imbalance causes power loss;
(2) can reduce piston and the piston ring frictional force in cylinder block, reach the purpose that promotes performance, prolongs its working life;
(3) help increasing air inflow, change the air fuel ratio of motor, make the engine combustion benefit more abundant, reduced the tail gas that in combustion process, produces, reach the purpose that promotes performance;
(4) adopt principal and subordinate's actuation mechanism, changed velocity ratio, when low speed, increased the output torque of motor; When high speed, make power output more steady, reduced in driving procedure, because road conditions are different, cause power loss, reach the purpose that promotes performance;
(5) under normal operating condition, motor each item performance can reach optimal combination, for the user uses best platform is provided, and also saves cost of use for the Consumer;
(6) can make the product discharging directly reach state III standard.
