Description

A kind of motor

Technical field

The utility model relates to a kind of combustion gas or fuel engine, especially a kind of gas engine of using low ignition point fuel belongs to a kind of engine technology.

Background technique

Fuel engine as motor car engine etc., has been at present a very ripe technology, and its structure mainly includes body, cylinder, piston, connecting rod, bent axle and valve mechanism etc.In valve mechanism, also have inlet and outlet passage and corresponding valve at least, also have nozzle and spark plug etc.Combustion oil sprays into from nozzle, through the spark ignitor burning, produces hot gas and expands, and promotes piston and moves in cylinder, and pass through externally outputting power such as bent axle, connecting rod.This motor can only adopt the higher fuel of burning-point usually, as gasoline, diesel oil etc., and for fuel such as hydrogen, the one, easy blast, the 2nd, burning-point is too low, and temperature is high slightly will spontaneous combustion, is difficult to control.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of simple in structure, and is easy to use, reliable, and energy-efficient effect and motor applied widely are arranged.It mainly is made up of body, cylinder, piston, connecting rod, bent axle and valve mechanism etc., described valve mechanism comprises valve, gas-entered passageway, exhaust passage etc., one valve depressed part is arranged at cylinder top, its top is equipped with a rotary valve, by described valve depressed part exhaust passage and gas-entered passageway are communicated with cylinder respectively, be provided with the passageway seals sheet corresponding to the place, exhaust passage, and be provided with the gas-entered passageway diaphragm seal corresponding to the gas-entered passageway place, below the valve depressed part above the cylinder, be respectively arranged with oil nozzle and spark plug.

Described valve two ends are equipped with synchronizing wheel, and the center of valve is provided with the cooling channel.

Described valve is arranged in the cylinder head of cylinder top, and periphery is provided with bearing shell, is provided with the propelling wedge that afterbody has spring at the back side of described bearing shell, and also is provided with lubrication groove in the inboard of bearing shell.

The utility model has adopted the valve cooling technology, therefore can use low ignition point fuel such as pure hydrogen gas; Adopt rotary valve, it can make the revolution of motor promote significantly; It has simple in structure, and is easy to use, reliable, and characteristics such as energy-efficient effect are arranged.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in detail: shown in the accompanying drawing 1, the utility model is mainly by body 1, cylinder 2, piston 3, connecting rod 4, compositions such as bent axle 5 and valve mechanism, described valve mechanism comprises valve 6, gas-entered passageway 7, exhaust passage 8 etc., one valve depressed part 9 is arranged at cylinder 2 tops, its top is equipped with a valve 6, this valve 6 is a rotary valve, by described valve depressed part 9 exhaust passage 8 and gas-entered passageway 7 are communicated with cylinder 2 respectively, be provided with passageway seals sheet 10 corresponding to 8 places, exhaust passage, and be provided with gas-entered passageway diaphragm seal 11 corresponding to gas-entered passageway 7 places, below the valve depressed part 9 above the cylinder 2, be respectively arranged with oil nozzle 12 and spark plug 13.

Rotary valve described in the utility model 6 two ends are equipped with synchronizing wheel, and the center of this valve is provided with cooling channel 14.

Described rotary valve 6 is arranged in the cylinder head 15 of cylinder 2 tops, and periphery is provided with bearing shell 16, is provided with the propelling wedge 17 that afterbody has spring at the back side of described bearing shell 16, and also is provided with lubrication groove 18 in the inboard of bearing shell 16.

Valve 6 described in the utility model is realized being communicated with of exhaust passages 8 and cylinder 2 by rotation by valve depressed part 9 and is closed.The effect of described gas-entered passageway diaphragm seal 11 and passageway seals sheet 10 is sealing functions, in addition, also has diaphragm seal or seal ring at rotary valve 6 cylinder intersections of living in, and they all have spring or reed to assist sealing in afterbody and side separately.The function of bearing shell 16 is the wearing and tearing of compensation valve and bears from the pressure in the cylinder, is specifically finished by the propelling key of back of bearing, at the afterbody that advances wedge spring is arranged, and in the bearing shell inboard lubrication groove is arranged.

The work of motor described in the utility model comprises: air-breathing active section: also be that the exhaust passage is closed, gas-entered passageway is opened; The compressing section: also be that gas-entered passageway is closed, the exhaust passage is closed; The acting section: plug ignition or oil nozzle oil spout, gas-entered passageway and exhaust passage are all closed; Exhaust section: open the exhaust passage, and gas-entered passageway is closed.

Valve described in the utility model also can be used for two stroke petrol engine and diesel engine except that can be used for four-stroke petrol engine and diesel engine.The lubricating system of valve is except that adopting the lubricant oil, available solid carbon etc. also, the valve shown in the accompanying drawing is the monolateral depression single hop of a single valve type, in addition also available dual valve (two valves), the depressed part of valve is opened in the side except shown in the drawings, also can drive in both sides or the centre.Depressed part also can be split into two sections recess that gas-entered passageway and exhaust passage are separated, and bearing shell also can use needle bearing or bearing to replace, and advances with the propelling wedge.

Pure air described in the utility model enters simultaneously that sunk part is entrained fuel gas by gas-entered passageway and sweeps only and bring into fuel gas and water-electrolyzing hydrogen inlet, enters cylinder interior again.
