Description

A kind of motor

Technical field

The utility model relates to a kind of motor, particularly a kind of motor.

Background technique

Internal-combustion engine mainly contains two types at present:

(1) reciprocating piston four stroke engine

The working procedure of reciprocating piston four stroke engine is an intake stroke: IO Intake Valve Opens, and exhaust valve closure, inflammable mixture is inhaled into cylinder.Compression stroke: when the air inlet working procedure at the end, intake valve and exhaust valve all are in closed condition, this moment, the inflammable mixture in the cylinder began to be compressed.Burning expansion expansion space stroke: send spark between sparking-plug electrode, compressed inflammable mixture is lighted.Piston then moves under this High Temperature High Pressure gas pressure, orders about crankshaft rotating by connecting rod and makes useful work.Exhaust stroke: exhaust valve opening, waste gas promptly begin to discharge by exhaust valve, and waste gas is released cylinder.

For four stroke engine, bent axle whenever takes two turns and does merit one time, and its torque characteristics is not desirable, and the spin balancing instability directly has influence on the power character and the fuel economy of output.Secondly, four stroke engine valve distribution mechanism complexity, component are more, the maintenance difficulty.Its three, the four stroke engine mechanicalness noise is bigger.

(2) reciprocating type two stroke engine

Toward the top dead center motion, it will finish air inlet and compression work process to piston, belong to first stroke of reciprocating motion of the pistons by lower dead center.Piston is moved to lower dead center by top dead center, and it will finish the working procedure of burning expansion acting and exhaust, belongs to second stroke of reciprocating motion of the pistons.When piston by lower dead center to top dead center motion and when Close All scavenge port and relief opening, then exhaust and gas exchange process stop, the fresh inflammable mixture in the cylinder will begin just to compress.When arriving to a certain degree, leaf valve is opened automatically, and inflammable mixture is inhaled in the crankcase.When piston continues to move upward, will be the time, send electrical spark by spark plug near top dead center, compressed inflammable mixture is lighted.Piston moves downward, and piston is promptly made useful work by connecting rod, bent axle.Leaf valve cuts out gradually automatically, and the inflammable mixture that enter in the crankcase this moment begins by precompression.When descent of piston during to exhaust open, waste gas just enters in the atmosphere by relief opening.When piston continued to come downwards to the scavenge port unlatching again, the fresh inflammable mixture that is compressed in advance in the crankcase just entered cylinder by scavenge port, and ordered about the interior waste gas of cylinder and further discharge, and was called scavenging process.

The two-stroke reciprocating motor whenever turns around acting once, and therefore rotation steadily.Do not need valve, component are few, so easy maintenance is inexpensive.The inertial force that to-and-fro motion produces is little, vibration is little, noise is low.Compare with four stroke engine, power was compared with four-stroke greatly when rotating speed was identical, and double explosive force is arranged.Therefore under identical volume, if mean effective pressure is identical, then power is 2 times.Its shortcoming is that the time of air intake-exhaust process is short, so fuel loss is big.Side at cylinder wall has gas port, and piston ring touches and is easy to wearing and tearing here.Because relief opening is on cylinder, thus be easy to overheated.Unstable at a slow speed.

The model utility content

It is big that technical problem to be solved in the utility model provides a kind of outputting power, the motor that the fuel utilization ratio is high.

Motor of the present utility model comprises cylinder body, collection chamber, firing chamber, relief opening and is positioned at cylinder body and directly contacts with the firing chamber, and directly provide the rotary-piston of power output to the external world, the rotatingshaft of rotary-piston is in its geometrical center, and rotary-piston is provided with at least one groove.

Directly connect an output shaft on the rotary-piston of described motor; The rotary-piston of described motor is a flywheel.

Owing to adopted and be positioned at cylinder body and directly contact with the firing chamber, and directly provide the rotary-piston of power output to the external world, the rotatingshaft of rotary-piston is in its geometrical center, rotary-piston is provided with the structure of at least one groove, revolve in the process that turns around at rotary-piston and just can externally do work at least once, and in the process of externally acting, just finished the process of gas collection, exhaust, to the utlity model has outputting power big thereby make, fuel utilization ratio advantages of higher.The special set positions of relief opening can allow fuel burn as far as possible fully.The setting of piston can more improve the utilization ratio of fuel.On cylinder body, be provided with at least two structures that comprise collection chamber and firing chamber, can further increase power output.

Below in conjunction with drawings and Examples the utility model is further described, but the utility model is not limited only to embodiment.
