Description
Technical field
The present invention relates to a kind of internal-combustion engine, particularly relate to a kind of internal-combustion engine with four cylinders, four-journey, reciprocating piston and bimodal protruding dish, is the improvement to existing Structure of Internal-Combustion Engine.
Background technique
From German engineer Diesel invention crank-linkage type internal-combustion engine, 100 for many years, and the internal-combustion engine of this structure is always as the mating power of automobile, tractor and other engineering machinery.In long-term using process, some shortcoming and defect of crank-linkage type internal-combustion engine progressively are familiar with:
1. the crank-linkage type internal-combustion engine when piston passes to crank to power by connecting rod, has also produced a side pressure to casing wall in the course of the work, has caused the eccentric wear of cylinder barrel and piston, and the working condition of internal-combustion engine is degenerated, and has shortened the working life of complete machine.
2. the crank-linkage type internal-combustion engine has determined that the swing inertial force of the reciprocal inertia force of its piston and connecting rod can not complete equilibrium, produces vibration in the running.
3. crank-linkage type Structure of Internal-Combustion Engine complexity, the processing technique of main parts difficulty is big, and required precision height, the complete machine weight that compares is bigger, thereby the manufacturing expense height.
4. the crank-linkage type internal combustion engine characteristics of motion, gas fuel burning rule and heat dissipation law during the outburst of incompatibility internal-combustion engine, thereby the thermal efficiency is relatively low.
In the evolution of internal-combustion engine, some internal combustion engines also once appearred both at home and abroad, as three-apexed rotor formula internal-combustion engine, protruding dish internal-combustion engine, balance internal-combustion engine, Stirling formula internal-combustion engine, to the top internal-combustion piston engine etc.,, there are various shortcoming and deficiency though above-mentioned internal-combustion engine successively comes out, never obtain practical application, wherein
(1). three-apexed rotor formula internal-combustion engine
This machine is simple in structure, volume is little in light weight, balance is good, and running steadily can not get solving but this internal-combustion engine deadly defect is a sealing problem, this machine is when work, the Stamping Steel Ribbon of triangle piston and the working surface of cylinder can not be permanently effective sealing, cause the pressurized gas in the working procedure to reveal, can not be permanently effective, running reliably, thereby be not applied.
(2). protruding dish, balance internal-combustion engine
These two kinds of internal-combustion engines were once introduced in " diesel engine design handbook ", but owing to its structure and other reasons, the processing technology complexity can not be used on automobile.
(3). Stirling formula internal-combustion engine
This internal-combustion engine is because its gas distribution system volume is excessive, and heaviness can not be as the power of motor vehicle.
(4). to the top internal-combustion piston engine
This internal-combustion engine once was external emerging a kind of internal-combustion engine, this machine two-piston relative movement, so balance is good, but this structure only limits to two stroke IC engine, and the scavenging process complexity, and volume is excessive, is not applied and promotes.
Summary of the invention
The objective of the invention is to overcome the prior art above shortcomings,, improve, provided a kind of novel internal-combustion engine with four cylinders, four-journey, reciprocating piston and bimodal protruding dish through research at the shortcoming of existing internal-combustion engine.It has the advantage of crank-connecting rod internal-combustion engine and three-apexed rotor formula internal-combustion engine, has not only overcome its shortcoming and defect, and also creative improvement on principle and structure, addresses the problem:
1. reduce oil consumption, reduce discharge of harmful gases, the main fuel consumption of crank-connecting rod internal-combustion engine, because its structure restricts new breakthrough can not be arranged, discharge of harmful gases such as nitrous oxide can't be effectively controlled.The present invention then can address these problems well, reduces the consumption and the discharge of harmful gases of main fuel effectively by the variation of protruding dish-type surface curve and compression ratio.
2. compare with the crank-connecting rod internal-combustion engine, the present invention reduces in the working procedure piston widely to the side pressure of cylinder barrel, has realized this just round even abrasion to fastness of cylinder barrel and piston substantially.
Pressure and impact force when 3. the key seat of crank-connecting rod internal combustion engine not only bears outburst, and heat load is bigger, is easy to generate distortion, and piston of the present invention does not have key seat, piston and piston rod can be realized pressure lubrication and cooling simultaneously, no key seat distortion.
4. the protruding dish of pair of rollers, return roller and fork all are rolling friction, compare the power of reducing friction with the sliding friction of crank-connecting rod internal-combustion engine, have improved reliability.
5. compare with the crank-connecting rod internal-combustion engine, the present invention replaces connecting rod by protruding dish roller mechanism, and protruding dish replaces the bent axle function, the protruding dish of the direct driving of roller on the piston changes linear reciprocating motion into and rotatablely moves, the centre does not have connecting rod, does not so just have bent bearing shell, parts such as connecting rod bearing shell yet.
Distribution device directly drives gas distribution plate by central principal axis, by being set in the distribution tappet in the bulge loop driving tappet seat on the gas distribution plate, tappet directly drives valve, finishes breathing action during the gas distribution plate rotation, compare with the crank-connecting rod internal-combustion engine, gas distribution structure height of the present invention is simplified.
Because the simplification advanced person of structure, volume weight reduces, and the manufacturing expense of the present invention of equal-wattage only is to make 50% of expense with power crank-connecting rod internal-combustion engine.
6. the crank-connecting rod internal-combustion engine exists the reciprocal inertia force of piston up-down and the swing inertial force of connecting rod in operation process, these two kinds of power are difficult to complete equilibrium, and revolving part main shaft of the present invention, protruding dish, belt pulley itself is exactly a counterbalance, piston return fork can both be realized symmetrical balance motion, the friction so the present invention works together.
7. the protruding disc spins of the present invention is 360 °, just breaks out four times, is equivalent to crank-connecting rod internal-combustion engine 8 cylinder workings, compares with the crank-connecting rod internal-combustion engine, power per liter doubles, and the main shaft of power output is located at the middle part and connects complete machine, has dwindled volume, make power per liter, specific power, weight/power ratio increases substantially.
