The invention discloses an engine cylinder head of a light electronic injection pedal motorcycle, and belongs to air cylinder heads. The engine cylinder head structurally comprises an air cylinder head body. A cylinder head air inlet is formed in the middle of the front side of the air cylinder head body, an air distribution chain chamber is arranged in the air cylinder head body, a cylinder head temperature sensor installing table is arranged on the portion, on the upper left portion of the cylinder head air inlet, of the air cylinder head body, a cylinder head temperature sensor installing hole is formed in the cylinder head temperature sensor installing table, and the tail end of the cylinder head temperature sensor installing hole is not communicated with an inner cavity of the air cylinder head body. Compared with the prior art, the engine cylinder head of the light electronic injection pedal motorcycle has the advantages that space limitation is effectively avoided, it is guaranteed that the cylinder head temperature value reflects the real condition of an engine, and good popularization and application value is achieved.
Description
Technical field
The present invention relates to a kind of cylinder head, especially a kind of light EFI pedal motorcycle engine cylinder head.
Background technique
At present, intelligent engine management system is extensive use on motorcycle, engine management system requires multiple sensors that relevant information is provided, judge the working state of motor for ECU, thereby control the output information of final controlling element, make engine operation at optimum igniting, oil spout state, thereby motorcycle is obtained optimum drive and environmental protection state.The position of cylinder head temperature sensor is wherein selected very important, particularly also to show consideration for the interference with other parts, therefore how to utilize limited space arrange the rigging position of cylinder head temperature sensor and ensure the actual working state that it reflects motor exactly, become the break-through point of realizing light motorcycle engine intelligent management system.
Summary of the invention
Technical assignment of the present invention is to provide a kind of light EFI pedal motorcycle engine cylinder head for above-mentioned deficiency of the prior art, and this kind of light EFI pedal motorcycle engine cylinder head has the advantages that to efficiently solve the limitation in space and ensure the time of day of cylinder head temperature value reflection motor.
The technical solution adopted for the present invention to solve the technical problems is: it comprises cylinder head body, the middle part, front side of described cylinder head body is provided with cylinder head suction port, in cylinder head body, be provided with distribution chain chamber, on the upper left cylinder head body of described cylinder head suction port, be provided with cylinder head temperature sensor mounting platform, in described cylinder head temperature sensor mounting platform, be provided with cylinder head temperature sensor mounting hole, the tail end of described cylinder head temperature sensor mounting hole does not communicate with cylinder head chamber body.
The center line of described cylinder head temperature sensor mounting hole is 5-25cm to the perpendicular distance of the center line of cylinder head suction port, and horizontal equivalent is 5-35cm.
The light EFI pedal motorcycle engine of one of the present invention cylinder head compared to the prior art, there is following outstanding beneficial effect: under the prerequisite of utilizing the confined space, ensure the reasonable installation of cylinder head temperature sensor and the interference with other component, choose reasonable is in the certain limit at cylinder head suction port place, utilize the closed hole on special hole and the intake elbow rubber wing eaves on fan guard to pass its wire harness and ensure that the wind of air cooling system circulates, therefore can realize the fuel oil injection work of engine management system, make motor under various operating modes, obtain the mixed gas of reasonable air fuel ratio, reduce discharge to reach, reduce the features such as oil consumption.

Embodiment
With reference to Figure of description 1 to accompanying drawing 4, the light EFI pedal motorcycle engine of one of the present invention cylinder head is described in detail below.
The light EFI pedal motorcycle engine of one of the present invention cylinder head, its structure comprises cylinder head body 4, the middle part, front side of described cylinder head body 4 is provided with cylinder head suction port 1, in cylinder head body, be provided with distribution chain chamber 3, on the upper left cylinder head body 4 of described cylinder head suction port 1, be provided with cylinder head temperature sensor mounting platform 5, in described cylinder head temperature sensor mounting platform 5, be provided with cylinder head temperature sensor mounting hole 2, the tail end of described cylinder head temperature sensor mounting hole 2 does not communicate with cylinder head body 4 inner chambers, in order to avoid the temperature of reflection can not reflect the working state of motor truly.
Cylinder head temperature sensor mounting platform 5 can not be in air port place, also ensure that the temperature that the cylinder head temperature sensor 8 in insertion cylinder head temperature sensor mounting hole 2 is measured can not produce wrong sudden change, so select as far as possible near cylinder head suction port 1 and the distribution chain chamber 3 of can not boring a hole.
The center line of described cylinder head temperature sensor mounting hole 2 is 5-25cm to the perpendicular distance of the center line of cylinder head suction port 1, and horizontal equivalent is 5-35cm.
By cylinder head temperature sensor mounting hole 2, cylinder head temperature sensor 8 is fixed on cylinder head body 4, be connected with wire harness by after the wing eaves of intake elbow 7 again through fan guard 6, directly correct information is passed to ECU, ECU is according to the correctly judge real work operating mode of motor of this information, thereby reasonably send Optimum spark advance angle, and determine to the amount of the signal oil spout of an oil spout of oil nozzle according to discharge time, the unnecessary oil return tube from oil pump is got back to fuel tank, the mist of oil ejecting mixes with the air of coming in from throttle body, form by the air fuel ratio of demarcating regulation, finally entering cylinder 9 burns.
Except the technical characteristics described in specification, be the known technology of those skilled in the art.
