Abstract
A stroke oscillating internal-combustion engine comprises a chassis, a crankshaft, a piston, a piston rod and an oscillating double-acting cylinder. Scavenging air ports of exhaust ports opened on a cylinder wall are connected with hollow short shafts at two sides of the cylinder, respectively. Oscillating shafts of the cylinder that are formed by two hollow short shafts can be oscillated in a bearing hole at upper part of the chassis as a scavenging air pipeline and an exhaust pipeline. The cylinder is divided into two working cavities by the piston sliding in the cylinder. The piston rod fixedly connected with the piston penetrates a central hole of end cover of the cylinder and movably connected with a rod journal of the crankshaft. A spindle of the crankshaft is mounted in the bearing hole at lower part of the chassis. The cylinder is oscillated, and then the cylinder, the piston, the piston rod and the rod journal are on the same straight line to reduce abrasion of the cylinder and lateral pressure, and increase torque. By using the double-acting cylinder, two ends of the piston act to realize four cylinders of four strokes, therefore the internal-combustion engine provided by the invention has advantages of simplified structure, reduced parts and lowered cost.
Description
Technical field
The invention belongs to a kind of internal-combustion engine, particularly a kind of one-stroke oscillating internal-combustion engine.
Background technique
Mostly common stroke piston combustion engine is slidercrank mechanism, and cylinder is fixed, and cylinder centerline and crankshaft axis coincide, piston easily produces side pressure in cylinder, increased the wearing and tearing of cylinder, has consumed effective merit, and complex structure, part is many, the cost height.And oscillating internal-combustion engine is because intake and exhaust and fuel oil, lubricant oil, chilled(cooling) water supply (CWS) difficulty are uncommon in life.China utility model patent ZL.97214002.6 discloses a kind of cylinder movement type internal combustion engine, in the cylinder head both sides minor axis is housed, cylinder is swung with cylinder head, a kind of oscillating cylinder thinking is provided, but flexible pipe, mode such as hinged have been adopted in intake and exhaust and fuel oil, lubricant oil, chilled(cooling) water supply (CWS), and it is very unreliable to work under high-speed motion state.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, with low cost, reliable, energy-conservation one-stroke oscillating internal-combustion engine, for achieving this end, technological scheme of the present invention is: a kind of internal-combustion engine of crank rocker mechanism comprises double-acting cylinder, piston, the piston rod of frame, bent axle, swing.Frame is fixed, crank spindle is installed in the bearing hole of frame lower, the cylinder wall middle part has scavenging port and relief opening, scavenging port is fixedlyed connected with the hollow stub shafts of cylinder both sides respectively with relief opening, hollow stub shafts can be swung in the bearing hole of the upper rack of cylinder both sides, and hollow stub shafts had not only been made the swing axis of cylinder but also respectively as scavenge line and exhaust duct.Cylinder is a double-acting cylinder, the piston that slides in the cylinder is divided into two work chamber up and down to cylinder, the rod journal that the piston rod of fixedlying connected with piston passes cylinder end piece center hole and bent axle flexibly connects, and cylinder is swung with respect to frame under the crankshaft-link rod effect during work.
Waste gas entered scavenge line when one-way valve was set in the hollow stub shafts as scavenge line with the prevention exhaust.
Establishing an end cap as the hollow stub shafts outer end of scavenge line is fixed on the frame, the steam line that end cap central bore is connected and fixed also forms sliding sleeve with hollow stub shafts and is connected, having the hole on the end cap in addition fixedlys connected with fuel, cooling water, lubricant oil supply line, the hollow stub shafts wall has the duct vertically and fixedlys connected with the pipeline of supply cylinder, duct on the hollow stub shafts is corresponding with the hole on the end cap, and hollow stub shafts and end cap are formed a guiding valve relative movement.
Fuel, lubricant oil, cooling water spray into cylinder through the pipeline of transfer pump, pipeline, ending cover hole, hollow stub shafts wall inner duct, supply cylinder.
The present invention compared with prior art has following advantage and beneficial effect: simple in structure, component are few, the power to weight ratio height, active force is on the bent axle contour, moment of torsion is big, because the cylinder swing, cylinder, piston, piston rod, rod journal reduce cylinder wear, reduce side pressure, increase moment of torsion during work on same straight line; Owing to adopt double-acting cylinder, the acting of piston two ends realizes that one-stroke makes a cylinder be equivalent to four of four-stroke machine, designs simplification, and component reduce, and cost reduces.
Description of drawings
The present invention is described in more detail below in conjunction with drawings and Examples;
This accompanying drawing is the structural representation sketch of the embodiment of the invention;
Reference character is: pipeline 13 ducts of 1 bent axle, 2 frames, 3 piston rods, 4 pistons, 5 swing type double-acting cylinders, 6 hollow stub shafts, 7 end caps, 8 one-way valves, 9 scavenging ports, 10 relief openings, 11 pipelines, 12 supply cylinders
Embodiment
The one-stroke oscillating internal-combustion engine is made up of bent axle 1, frame 2, swing type double-acting cylinder 5, piston 4, piston rod 3 as shown in the figure, frame 2 is fixing, bent axle 1 is contained in the bearing hole of frame 2 bottoms, both sides, cylinder wall middle part have scavenging port 9 and fixedly connected with two hollow stub shafts 6 respectively with relief opening 10, two hollow stub shafts are installed in as the swing axis of cylinder in the bearing hole of upper rack of both sides, and hollow stub shafts had not only been made the swing axis of cylinder but also made the scavenge line and the exhaust duct of cylinder respectively; The piston 4 that slides in the swing type cylinder 5 is divided into two work chamber to cylinder, and the rod journal that the piston rod 3 of fixedlying connected with piston passes cylinder end piece center hole and bent axle flexibly connects, and cylinder is swung with respect to frame 2 under the crankshaft-link rod effect during work.One-way valve 8 stops waste gas to enter scavenge line.
Because one-stroke oscillating internal-combustion engine cylinder, bent axle, connecting rod all is a movable part, the fuel of supply cylinder, lubricant oil, cooling water is provided with a guiding valve and solves fixing pipeline and movable cylinder connectivity problem, scheme is: establish an end cap 7 as the hollow stub shafts outer end of scavenge line and be fixed on the frame, the steam line that end cap central bore is connected and fixed also forms sliding sleeve with hollow stub shafts and is connected, have hole and fuel on the end cap in addition, cooling water, lubricant oil supply line 11 is fixedly connected, the hollow stub shafts wall has duct 13 vertically and fixedlys connected with the pipeline 12 of supply cylinder, duct 13 on the hollow stub shafts is corresponding with the hole on the end cap, and hollow stub shafts and end cap are formed a guiding valve relative movement.
Fuel, lubricant oil, cooling water spray into cylinder through transfer pump, pipeline, ending cover hole, hollow stub shafts wall inner duct, the pipeline that enters cylinder.
Can adopt the inside and outside while type of cooling of splash lubrication oil outside in-cylinder water injection, cylinder for this machine of weight that reduces cylinder.
The lubricated employing in the cylinder to in-cylinder injection lubricant oil; Or water-oil mixture, emulsified liquid; Or water base lubricant.
