Abstract

A special engine without crankshaft-connecting rod mechanism and cam-tappet mechanism can do work four times when mainshaft rotates by one turn. In its cylindrical shape cylinder, there are a rotary digonal rotor fixed to the mainshaft, and the stoppers coordinating with it for doing work and exhaust, hole-shielding blocks and monodirectional valve coordinating with combustion chamber work, which are installed on cyliner body. Its advantages include uniform heating of cylinder body, easy manufacture, high reliability and saving energy.

Description

Engine with digonal rotor

The present invention relates to a kind of motor, especially a kind of motor with digonal rotor.

In engine design was in recent years made, in order to improve the efficient of motor, engineers and technicians once used many energy, sought the extraordinary type that can substitute conventional reciprocating formula motor.Epitrochoidal engine promptly is an example, but many inherent defects in view of rotary polygonal piston engine, can not popularize in an all-round way eventually, as the radial seal problem of three-apexed rotor in the cylinder body profile, the two arc inner rotary line precision process problems of cylinder body profile, the heat dissipation problems in the hot arc of cylinder body firing tip district etc. still are difficult to low cost so far and solve.

Purpose of the present invention, promptly provide a kind of mechanical efficiency height, simple in structure, easily manufactured extraordinary type: engine with digonal rotor, this motor crankshaft-free connection rod mechanism, no tappet mechanism takes two cylinder symplex structures, therefore main shaft whenever circles and promptly produces output pulses four times, and main shaft bears quite little radial thrust, and can make the combustion gas that is in expansion space stroke do sufficient reexpansion in cylinder, therefore, the mechanical efficiency height, energy-saving effect is obvious.

Below, illustrate in conjunction with the accompanying drawings.

In cylinder body 1, produce axial cylindrical body cylinder 2, on the disk at two ends, clamped end cap 3 at cylinder axis, in cylinder, the digonal rotor 4 of big cam shape is installed, digonal rotor is fastened on the main shaft 5 of output power, and main shaft supports with end cap.Block 6 is installed on the cylinder body, spring 7, air outlet flue 8, spray orifice 9, firing chamber 10, spark plug 11, the safety check 12 that leads to the firing chamber leads to the screening orifice plate 13 of spray orifice, calms the anger 14, air pump assembly 15.

The working procedure of this motor is as follows:

The fuel-air mixed gas of exporting from 15 compressions of air pump assembly (or air) hides orifice plates 13 through 14 promotions of calming the anger and hides tight spray orifice 9, and pushes safety check 12 open, injects in the firing chamber 10.When digonal rotor 4 tops are close to the cylinder profile and are gone in fumarole 9 (be equivalent near the top dead center of reciprocating engine piston this moment), spark plug 11 igniting (or oil sprayer oil spout), so, high-temperature high-pressure fuel gas promptly compresses safety check 12 and pushes open and hides orifice plate 13, promote digonal rotor 4 works done from spray orifice 9 ejections, meanwhile, combustion gas acts on the block 6 that is ejected by spring 7, block is ridden on the digonal rotor 4, make the unidirectional expansion of combustion gas, after combustion gas enters cylinder 2, carry out sufficient reexpansion, promote the digonal rotor secondary-working, until digonal rotor open row air flue 8, expansion space stroke finishes.At this moment, part waste gas is discharged through air outlet flue, part still remains in the entire cylinder, discharges during by digonal rotor work done next time, in fact carries out simultaneously just as the expansion space stroke and the exhaust stroke of reciprocating-piston engine, and air inlet and compression process, then carry out in air pump, principle is identical with conventional air pump, but air pump axle and main shaft run-in synchronism, air pump is compressed to about top dead center, promptly lights a fire in the firing chamber.

Digonal rotor 4 and main shaft 5 fastening one, its cam external frame curve satisfies the characteristics of motion of block 6, waits deceleration curve for waiting accelerations, and promptly block work etc. quickens uniform retarded motion during the jack-up block, after block is crossed the cam top, continues to do to wait the acceleration uniform retarded motion.

Block 6 is seen Fig. 2, bearing post 1 by elongated cylindrical, form with some blocks of Heat sinks 3 rigidity that are connected them with the curved baffle 2 of bearing post concentric, outer arced surface at baffle plate 2 has a pressure bearing head 4 by the three-apexed rotor end, Heat sink 3 is towards the cambered surface of digonal rotor, during motion not should with the make a difference friction of baffle plate 2 characteristics of motion of digonal rotor.

Fig. 3 is the plan view of link stopper 6.

Fig. 4 is the position of safety check 12 between air flue and firing chamber, and wherein 10 is the firing chamber, and 11 is spark plug, and 12 is safety check, and 14 for calming the anger.

Fig. 5 is a longitudinal sectional view of the present invention.

In the design of this motor, change the ratio of air pump volume of cylinder and combustion chamber volume, can change compression ratio, the volume that changes combustion chamber volume and rotor work done can change the ratio of reexpansion.

Change the position of block root on cylinder body and the shape of block retaining gas face, can change the pressure that block is adjacent to digonal rotor.

The present invention compares with conventional engines or epitrochoidal engine, has advantages such as simple in structure, sufficient combustion, energy conservation and consumption reduction effects be obvious.
