Abstract
The utility model discloses a distributing device of three-valve engine for motorcycle which is characterized in that an exhaust passage (10) and a Y-shaped inlet channel are arranged on a cylinder head (1); the exhaust passage (10) is connected with the spherical surface (14) of a fluey sphericity combustion chamber (11); two horns of fork of the inlet channel (9) are connected with the fluey sphericity surface (13) of the fluey sphericity combustion chamber (11); a locking device (12) fixes an intake valve (3), an intake valve spring (2), an exhaust valve (7) and an exhaust valve spring (6) inside the cylinder head (1); one end of an intake rocker (4) is connected with the intake valve spring (2), while the other end of the intake rocker (4) is connected with a distributing cam shaft (5); one end of an exhaust rocker (8) is connected with the intake valve spring (2), while the other end of the exhaust rocker (8) is connected with the distributing cam shaft (5). The utility model can improve the charging efficiency and output per litre of a methodological engine, thereby having a wide application range.
Description
(1). technical field
The utility model belongs to engine art, particularly a kind of air distributing device that is used for multivalve engine.
(2). background technology
At present, in small-displacement engine of motorcycle, adopt two valves i.e. an inlet valve and an exhaust valve, combustion chamber is a semisphere.The charge efficiency of driving engine in this way is low, and the output per litre of driving engine is low.
(3). summary of the invention
The purpose of this utility model provides a kind of motor bike three-valve engine air distributing device.It can improve the charge efficiency and the output per litre of driving engine, and can improve engine power performance.
For reaching above-mentioned purpose, the utility model comprises cylinder head, inlet-valve spring, inlet valve, intake rocker, distribution cam axle, the exhaust valve spring, exhaust valve, exhaust rocker arm, inlet channel, exhaust duct, it is characterized in that being provided with on cylinder head exhaust duct and " Y " shape inlet channel, the sphere of its exhaust duct and fluffy spherical combustion chamber joins, and two prongs of inlet channel and the fluffy face of fluffy spherical combustion chamber join; Latching device is fixed on inlet valve, inlet-valve spring and exhaust valve exhaust spring in the cylinder head; Intake rocker one end is connected with inlet-valve spring, and the other end is connected with distribution cam axle; Exhaust rocker arm one end is connected with inlet-valve spring, and the other end is connected with distribution cam axle.
Forming with sphere of fluffy spherical combustion chamber by fluffy.
The utility model can make the engine cylinder air inlet more abundant owing to be provided with two admission ports at combustion chamber, burning indoor exhaust air less residue, and the charge efficiency that has improved and the output per litre of motivation, engine power performance increases.The utility model adopts fluffy spherical combustion chamber, can two admission ports and an exhausr port be arranged on wherein in the limited space of combustion chamber, and the manufacturing characteristic of simple is arranged.The utility model is applicable on the motor cycle engine of discharge capacity less than 125ml, can constitute the motor bike three-valve engine of various models, therefore also has advantage of wide range of application.
Below in conjunction with accompanying drawing the utility model is described further.

(5) specific embodiment
Referring to Fig. 1 and Fig. 2.Exhaust duct 10 and " Y " shape inlet channel 9 are set on cylinder head 1, exhaust duct 10 joins with the sphere 14 of fluffy spherical combustion chamber 11, two prongs of inlet channel 9 and fluffy 13 of fluffy spherical combustion chamber 11 are joined, being made up of fluffy 13 and sphere 14 of fluffy spherical combustion chamber 11.Latching device 12 is fixed on inlet valve 3, inlet-valve spring 2 and exhaust valve 7 exhaust springs 6 in the cylinder head 1; Intake rocker 4 one ends are connected with inlet-valve spring 2, and the other end is connected with distribution cam axle 5; Exhaust rocker arm 8 one ends are connected with inlet-valve spring 6, and the other end is connected with distribution cam axle 5.
When driving engine is started working, near the top dead point of engine exhaust stroke, distribution cam axle 5 drives intake rocker 4 and drives two inlet valves, 3 unlatching combustion chambers 11, miscellaneous gas enters combustion chamber 11, near the engine compresses bottom end of stroke, air inlet spring 2 drives two inlet valves 3 and closes combustion chamber 11.Near the bottom dead point of expansion stroke, distribution cam axle 5 drives exhaust rocker arm 8 and drives an exhaust valve 7 unlatching combustion chambers 11, and waste gas is discharged combustion chamber 11, and near the top dead point of intake stroke, exhaust spring 6 drives exhaust valves 7 and closes exhausr port.And so forth, the engines distribution device is constantly worked.
Can be arranged on two admission ports and an exhausr port wherein being made up of fluffy 13 and sphere 14 of fluffy spherical combustion chamber 11 in the limited space of combustion chamber, makes the combustion chamber manufacturing simple.
