Abstract
The utility model discloses a parallel double cylinder engine, which comprises a cylinder body which has a left and a right parallel cylinders. A chain chamber is arranged between the two cylinders. A cylinder head is arranged above the cylinder body. Two combustion chambers are arranged above the two cylinders. A cam shaft is arranged above the cylinder head. A crank positioned under the cylinder body penetrates through a chain chamber arranged on the cylinder body to drive a cam shaft through a chain of the cam shaft. The cam shaft drives a rocking arm arranged above the cylinder head, and the rocking arm drives an air feeding and draining door to reciprocate. Two air feeding passages and two air draining passages are arranged on the cylinder head. A waste gas purifying device is arranged between the air draining passages of an air draining passage of the engine and a one-way valve. Air holes communicated with the air draining passages are arranged on the combined surface of the cylinder head and the cylinder body. Through holes butted with the air holes are arranged on the cylinder body and communicated with the one-way valve through pipelines. Thereby, a secondary air passage from the one-way valve, through the through holes and the cylinder head of the cylinder body to the air draining passages is formed. The utility model which has a good purifying effect can not affect the heat radiation effect and the appearance of the engine.
Description
Technical field
The utility model relates to the technical field of motor, and is special relevant with the structure of engine with two juxtaposed cylinders.
Background technique
In recent years, along with deepening continuously of reform and opening-up, especially since the China joined WTO, the automobile of China, motorcycle industry have all had development at full speed, China has become world motorcycle big producing country, volume of production and marketing leaps to the first in the world, and outlet leaps to the second in the world, and motorcycle has become the electronic product of the tool globalization feature of China.At home, motorcycle in small and medium-sized cities and vast rural area get the nod, become requisite important constituent element in the people life.
But, in the using process of motorcycle, can cause irreversible various pollution to environment, wherein exhaust gas discharged is exactly one to pollute greatly during engine operation.At present, the method for vehicle motor befouling environment is all reduced in countries in the world in research.
In the prior art, different motors, its waste gas cleaning plant also has nothing in common with each other.The motor that has does not still have waste gas cleaning plant, and the waste gas of discharging during these engine operation can not get purifying, and waste gas directly is discharged in the air, and environment has been caused very big pollution; Though the motor that has again has waste gas cleaning plant, because the unreasonable structure of purification plant, the laying of secondary air path has directly damaged radiating fin, so, there is the shortcoming that influences radiating effect and destroy the motor outward appearance.
Therefore,, develop the waste gas cleaning plant that is fit to this structure engine,, become problem demanding prompt solution in the industry to have good purifying effect and not influence radiating effect and the motor outward appearance at the motor of specified structure.
The model utility content
The purpose of this utility model is to provide a kind of engine with two juxtaposed cylinders, makes its waste-gas cleaning effective, and does not influence radiating effect and motor outward appearance.
For reaching above-mentioned purpose, solution of the present utility model is:
Engine with two juxtaposed cylinders, comprise a cylinder block, cylinder block contains a left side, right two cylinders arranged side by side, be chain chamber between two cylinders, a cylinder head is installed above cylinder block, and the top corresponding to two cylinders forms two firing chambers, camshaft is housed above cylinder head, the bent axle that is positioned at cylinder block below passes chain chamber drive cam shaft on the cylinder block by the camshaft chain, camshaft drives the rocking arm of cylinder head top; rocking arm promotes into; exhaust valve is reciprocating; two intake ducts and two air outlet flues are arranged on cylinder head; waste gas cleaning plant is arranged between the air outlet flue and one-way valve of motor; offer the pore that communicates with air outlet flue on the junction plane of cylinder head and cylinder block; and on cylinder block, offer the through hole that pore therewith docks, and this through hole relends and helps pipeline to be communicated with one-way valve, forms thus by the through hole of one-way valve through cylinder block; the pore of cylinder head is to the secondary air path of air outlet flue.
The through hole of above-mentioned cylinder block is " L " type, and " L " one section is parallel to radiating fin and gos deep in the cylinder block, another section of " L " by the inside of cylinder block to extending with the junction plane of cylinder head and directly docking with the pore of cylinder head.
After adopting said structure, the utility model is owing to increase the secondary air path between the air outlet flue of engine with two juxtaposed cylinders and one-way valve, thus can be in air outlet flue input air, waste gas is reacted with air in air outlet flue, thereby reaches the effect of preferable purifying exhaust air.And path of the present utility model gets around the radiating fin of motor, enters the air outlet flue of motor by the through hole of cylinder block through the pore of cylinder head, neither influences the outward appearance that radiating effect has guaranteed motor again.

Embodiment
See also shown in Fig. 1 and 2, be the embodiment of the utility model engine with two juxtaposed cylinders, comprise a cylinder block 1, cylinder block 1 contains a left side, right two cylinders arranged side by side 11, be chain chamber 12 between two cylinders 11, a cylinder head 2 is installed above cylinder block 1, and the top corresponding to two cylinders 11 forms two firing chambers 21, camshaft 22 is housed above cylinder head 2, the bent axle 3 that is positioned at cylinder block 1 below passes chain chamber 12 drive cam shaft 22 on the cylinder block 1 by camshaft chain 4, camshaft 22 drives the Rocker arm 5 of cylinder head 2 tops; Rocker arm 5 promotion intake valve 23 and exhaust valve 24 are reciprocating, and two intake ducts 25 and two air outlet flues 26 are arranged on cylinder head 2.
Cooperate shown in Fig. 3 and 4, waste gas cleaning plant is arranged between the air outlet flue 26 and one-way valve (not shown) of motor.On the junction plane of cylinder head 2 and cylinder block 1, offer the pore 27 that communicates with air outlet flue 26, and on cylinder block 1, offer the through hole 13 of 27 butt joints of pore therewith, this through hole 13 relends and helps the pipeline (not shown) to be communicated with one-way valve, forms thus by one-way valve through the pore 27 of the through hole 13 of cylinder block 1, the cylinder head 2 secondary air path to air outlet flue 26.About the tightness of joint between each hole, be to realize by gasket seal, the key of the non-this case of gasket seal, this paper does not do and gives unnecessary details.
Like this, air by in the one-way valve input air outlet flue 26, reacts waste gas, thereby reaches the effect of purifying exhaust air with air in air outlet flue 26.
The through hole 13 of cylinder block 1 is " L " type among this embodiment, and " L " one section is parallel to radiating fin 14 and gos deep in the cylinder block 1, another section of " L " by the inside of cylinder block 1 to extending with the junction plane of cylinder head 2 and directly docking with the pore 27 of cylinder head 2.Like this, the secondary air path of whole purification plant gets around the radiating fin 14 of motor, enters air outlet flue 26 by the through hole 13 of cylinder block 1 through the pore 27 of cylinder head 2, neither influences the outward appearance that radiating effect has guaranteed motor again.Certainly, through hole 13 of the present utility model also can adopt other form to avoid radiating fin 14, does not influence the effect that radiating effect has guaranteed the motor outward appearance again to reach.
