Abstract

The present invention discloses an engine, particularly a gasoline engine having the advantages of reasonable motion, energy saving, high conversion efficiency and no lateral component force. The present invention is composed of a fuel ignition system and a cam shaft, and a main shaft provided with at least one main driving wheel assembly and a horizontal lateral power cylinder corresponding to the main driving wheel assembly are arranged on the present invention, wherein one end of a piston rod in the power cylinder is hinged with one end of a chain arranged on the edge of the main driving wheel assembly. Compared with the prior art, the present invention has the advantages of more reasonable piston motion, no lateral component force, small and uniform abrasion to a cylinder sleeve, uniformly prolonged overhaul periods, no dead points, simple manufacture techniques, decreased cost and low energy consumption. The force arm of torque conveyed to the main shaft is always in the longest position, and therefore, power conversion efficiency is obviously increased and waste gas can be discharged completely. The engine of the present invention can be used for other fuel combustible gas, such as alcohol, gasoline, natural gas, etc., and can become the engine of various automobiles, ships and air crafts and other machines.

Description

Petrol engine

Technical field

The present invention relates to a kind of motor, it is reasonable particularly to relate to a kind of motion, energy-conservation, conversion efficiency is high, the petrol engine of no cross component force.

Background technique

The well-known power of motor at present is by the driving torque of bent axle transmission of power to be gone out, and the power that bent axle obtains comes from piston crank mechanism, the crank that is to say when piston runs to " dead point " for single cylinder this moment of the bent axle length of its moment of torsion arm of force in vertical state is zero, have only when 90 ° of crankshaft rotating, the arm of force of its bent axle is just the longest, therefore the power on the piston rod passes to conversion efficiency that bent axle passes by bent axle again less than 0.5, conversion efficiency reaches 1 or near 1 o'clock, being only dynamically, also is the direction that people pursue.And present motor is difficult to the waste gas emptying when waste discharge gas.

Motor in the past makes piston produce cross component force in running owing to be the motion mode of crank-connecting rod piston in addition, causes the casing wall uneven wear, often presents ellipticity and causes motor to scurry oil, and power reduces, the overhaul of need marching into the arena.In a word motor in the past because be that the structural type of bent axle, piston rod must cause existingly wasting energy, defective such as inefficiency, conversion efficiency are low, this has caused domestic and international colleagues' concern, all in the dynamical motor car engine of developmental research, can regrettably up to the present not see the report of achieving success as yet.

Summary of the invention

The present invention is directed to the problem that prior art exists, provide a kind of high-effect, rational in infrastructure, no cross component force, manufacturing process are simple, the petrol engine of prolonging overhaul period.

The present invention realizes that the goal of the invention technological scheme is: petrol engine, form by oil-firing system and camshaft, at least be provided with on it main driving wheel assembly main shaft and with the corresponding horizontal horizontal ram of main driving wheel assembly, an end of the piston rod in the ram is hinged with chain one end of being located on the main driving wheel assembly edge.

Be provided with the piston that fuses with piston rod in the described ram, the one end is the cylinder cap A which is provided with suction, exhaust valve, igniting chamber, the other end is the cylinder cap B which is provided with vent, and the other end of piston rod stretches out cylinder cap B, and air-breathing spring of suit is by pressing plate, dowel fixes on it.

Described main driving wheel assembly comprises that the one side and the sprocket wheel of bicycle freewheel analog structure establish pawl wheel in it and be installed on the main shaft, another side is that the interruption umbrella fluted disc that is interrupted the umbrella tooth is arranged, and be interrupted with another that umbrella gear is relative to be loaded on the main shaft, two have the bevel pinion that can be meshed with it on being interrupted between the umbrella gear.

Interruption umbrella tooth on the described interruption umbrella fluted disc is two sections and is and is symmetrical arranged that its pairing central angle is 48 °.

Interruption umbrella tooth on the described interruption umbrella gear is four sections and is and is symmetrical arranged, wherein two sections pairing central angles are 44 °, the central angle of other two sections correspondences is 46 °, and central angle is that the umbrella tooth of 44 ° of correspondences is that 46 ° of corresponding umbrella spaces of teeth are arranged on the circumference with central angle.

Described main shaft one end is fixed with a gear, and is meshed with the timing gear of cam axle head.

Described ram is fixedlyed connected with frame by link, is provided with cylinder sleeve in its cylinder body.

One end of described chain is fixed on the chain fixed base at sprocket wheel edge.

The pairing central angle of sprocket at described sprocket wheel edge is 110 °.

Advantage of the present invention and effect are as follows:

The present invention compared with prior art, owing to cancelled the bent axle of conventional engines, and adopt the main driving wheel assembly is set on main shaft, link to each other with piston rod by chain, chain rod, and on another external part of piston rod a series of technical measures such as air-breathing spring of suit and make piston motion more reasonable through evidence, no cross component force, so little and even prolonging overhaul period of wearing and tearing of cylinder sleeve, the arm of force that passes to the moment of torsion of main shaft is in the longest position all the time, more do not have " dead point ", cause power-converting efficient obviously to improve.Make that the gas of waste discharge for the first time row's is clean owing to be interrupted the structure setting of umbrella gear 18, for the second time piston is not compressed to the bottom during pressurized gas, leave certain space, it is more reasonable to be that the present invention designs, engine energy-saving of the present invention, manufacturing process are simple, it is few with energy consumption to reduce cost, and objectively also reduces operating cost for the user.
