Description
Technical field
The present invention relates to a kind of engine structure, especially a kind of improvement structure of reciprocating piston type internal combustion motor.
Background technique
The reciprocating piston type internal combustion motor is to burn in cylinder combustion after fuel oil and the air mixing, and combustion gas is expanded and promoted reciprocating motion of the pistons, again by the connecting rod output torque.In its working procedure, because the friction energy-dissipating of piston and cylinder, and oil inflame causes the overheated need of cylinder body to be lowered the temperature by cooling system, and these factors cause engine operation efficient not high.Number be 200510083108.2 Chinese patent discloses a kind of electric power gas-liquid conversion engine, solved the small-power drive motor and can not export problem that its structure is complicated, is unsuitable for the reciprocating piston type internal combustion motor than high pulling torque.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of engine structure, under same cylinder structure and same energy initial conditions, and bigger moment of torsion and the power of comparable conventional reciprocating piston internal-combustion engine output.
The present invention adopts following technological scheme, comprise cylinder, first piston, it is characterized in that: also comprise the fluid cylinder and second piston, the cylinder body of described fluid cylinder links to each other with the cylinder body of cylinder and constitutes the gas-liquid cylinder of integral structure, be full of hydraulic oil in the cylinder body between the first piston and second piston, the piston area of second piston is greater than the piston area of first piston, and second piston links to each other with connecting rod.
Its principle is: hydraulic oil adopts resistant to elevated temperatures hydraulic oil, have that thermal conductivity is good, low melting point, higher boiling, high burning-point or characteristics such as not flammable, the high temperature condition of inside and outside wall in the time of can bearing gas-liquid cylinder work, can not be vaporized or burn, can do not congealed under the low temperature, hydraulic oil becomes liquid all the time when engine operation.The gas-liquid cylinder structure of integral type, first piston had both served as cylinder piston, serve as liquid cylinder piston again, because second piston area is greater than the first piston area, fluid cylinder is full of hydraulic oil, when the masterpiece of the gas generation of burning in the cylinder is used on the first piston, according to Pascal's law, first piston is identical with pressure on second piston, and second piston area is greater than the first piston area, active force on second piston can be exaggerated, and connecting rod is the bigger moment of torsion of conventional engine output of comparable same cylinder structure on second piston.Because air cylinder structure is identical, given combination gas is under identical operating conditions, and the angular velocity of bent axle is identical, because the power P=moment of torsion * angular velocity omega of motor, so under same energy initial conditions, it also can be than the common bigger power of conventional engine output.In other words, under the output condition of equal-wattage, it can save the energy more than common conventional engine, reduces oil consumption.Secondly, the gas-liquid cylinder structure of this integral type, hydraulic oil can be immersed into the inboard wall of cylinder block of the following cylinder of first piston, play lubricated cylinder casing wall, can reduce the friction of cylinder piston and cylinder wall, cylinder piston under the high temperature is effectively lowered the temperature, have the effect in the working life that prolongs piston and motor.
A kind of improvement is that the housing structure of described gas-liquid cylinder becomes " recessed " font structure.This structure, because the whole outer wall of the hydraulic pressure oil ring bag cylinder in the fluid cylinder, when first piston goes upward to top dead center, hydraulic oil in the fluid cylinder promptly is immersed into the inboard wall of cylinder block of the following cylinder of first piston, the whole cylinder part of cylinder is all by the hydraulic oil submergence because the good heat conductive performance of hydraulic oil, can make gas-liquid cylinder evenly, quick heat radiating, improve the heat dispersion of cylinder effectively, guaranteed the efficient operation of external engine cooling system.
The another kind of improvement is housing structure one-tenth " protruding " font structure of described gas-liquid cylinder.This structure, hydraulic oil only contact the inwall of cylinder portion, but the whole outer wall of cylinder block peripheral hardware of gas-liquid cylinder cooling system, and it is simple in structure, and is easy to implement.
Adopt the present invention, have following advantage:
(1) the exportable bigger moment of torsion of the present invention, under identical power output condition, the conventional engine of comparable same cylinder structure is saved the energy more, reduces oil consumption; (2) the gas-liquid cylinder structure of integral type helps the cylinder block heat radiation, has improved the heat radiation energy property of cylinder; (3) but hydraulic oil self oiling cylinder casing wall; (4) can effectively prolong working life of piston and motor.
