Abstract
Disclosed is a reciprocating internal combustion engine with a double-sided piston and an arc cylinder body, which is characterized in that the internal combustion engine is provided with an arc cylinder body (4) and double cylinder covers (15,16); a double-sided piston (5) matching with the arc cylinder body (4) is arranged in the arc cylinder body; intake valves (1), exhaust valves (2), spark plugs or oil spray nozzles are arranged on the two cylinder covers which are respectively sealed and connected with the cylinder body (4); the double-sided piston (5) is in sliding contact with the inner wall of the arc cylinder body (4), with the two head faces (9,10) respectively forming a first cylinder and a second cylinder (17,18) together with the inner head faces of the two cylinder covers; and the central part of the double-sided piston (5) is connected with the upper end of a connecting rod (6) through a shaft. The reciprocating internal combustion engine has the advantages that: 1, since the piston has long stroke and big compression ratio, the output power is big; 2, the two cylinders share one double-sided piston, so the output power is big and the efficiency is high; 3, the crank pin has only one stress point, so the crank pin is steady when moving at high speed, and no balancing device is required.
Description
Technical field
The utility model relates to motor, particularly a kind of double-faced piston arc cylinder body reciprocating internal combustion engine.
Background technique
Ordinary internal combustion engine is to adopt single cylinder, the multi-cylinder engine of piston moving linearly in cylinder mostly, as V-type twin-tub quartastroke engine etc., the straight line motion of its piston from the top dead center of cylinder to lower dead center, repeating the work cycle of air-breathing, compression, acting and four strokes of exhaust, its shortcoming: 1. relatively large, the Heavy Weight of volume, output power are little; 2. the force bearing point on its crankpin is two, and it vibrates greatly when running at high speed, and stationarity is relatively poor, need add Equilibrator in addition; 3. its bent axle girth twice that is length of piston travel, piston stroke is short, and compression ratio is little, inefficiency.
Summary of the invention
The utility model provides the double-faced piston arc cylinder body that a kind of volume is little, output power is big, efficient is high reciprocating internal combustion engine in order to overcome above-mentioned shortcoming.
Described double-faced piston arc cylinder body reciprocating internal combustion engine comprises transmission shifting mechanism, lubrication system, cooling system, connecting rod, bent axle, crankpin, piston ring, the lower end of connecting rod connects by crankpin and bent axle axle, it is characterized in that: described internal-combustion engine is provided with the arc cylinder block, two cylinder head, in the arc cylinder block, be provided with double-faced piston with its coupling, on two cylinder head, be respectively equipped with intake valve, exhaust valve, spark plug or oil nozzle, described pair of cylinder head is tightly connected with cylinder block respectively, double-faced piston and the sliding contact of arc cylinder block inwall, its both ends of the surface constitute first with two cylinder head interior edge faces respectively, second cylinder, the double-faced piston middle part connects with the small end axle.
Described arc cylinder block middle part lower wall also is provided with the reciprocal groove of connecting rod.
The stroke of described double-faced piston in the arc cylinder block equates with the girth of connecting bar and crankshaft.
First, second cylinder of the present utility model is finished air-breathing, compression stroke respectively, and after the igniting of second cylinder, double-faced piston is finished expansion stroke, and first cylinder is finished compression stroke, so repeatedly circular work.Be characterized in: 1. because the stroke of piston is long, its compression ratio is big, output power is big; 2. not only output power is big, efficient is also high for two shared double-faced pistons of cylinder; 3. the force bearing point on the crankpin is one, runs at high speed steadily, does not need Equilibrator.
The utlity model has simple in structure, volume is little, output power is big, the simple advantage of the steady manufacturing process that runs up.
