Abstract

The utility model relates to a compression ignition rotor motor composed of a cylinder body, a blade, a spring, a rotor, a sealing plate, a crankshaft and a pressure oil pump. The blade on the rotor of an inner circular arc surface of the cylinder is abutted to the inner circular arc surface of the cylinder under the force action of the spring to form dynamic seal, and the end surface dynamic seal is formed by using a rotor sealing strip, a sealing pin and a blade sealing strip. The rotor drives the blade to slide with variable volume in the cylinder. A motor shaft simultaneously drives an eccentric pressure oil pump to supply fuel oil, and the compression natural principle of combustible mixed gas is used to produce a four-stroke operation compression ignition type rotor motor. The motor has the advantages of compact and simple structure, small size, large horsepower, fuel saving, high mechanical efficiency and long service life.

Description

Compression ignition RC engine

The utility model is the compression ignition RC engine that belongs to rotary engine.

Existing motor is such as reciprocating type operation motor, they have four-journey and two strokes respectively, but their piston all is to belong to the linear reciprocation operation must the conversion through connecting skewer, bent axle could realize its garden rotation, therefore the outputting power of motor is restricted, again because of the combination of multi-cylinder body with there is complicated ignition system to demonstrate bulky complex, mechanical efficiency is low, still has the deficiency of the ignition system of cooling effect difference and complexity such as " rotary-piston power plant " (93219450.8) of Chinese patent.The utility model adopts cylinder body and vane rotor directly to be combined into admission, compression, burning, exhaust four-stroke engine, and utilize compression autoignition principle after gasoline and the air mixing, cancel its ignition system and demonstrate simple in structure, under the active force that engine rotor rotates, implement cooling, the working life that can improve rotor motion spare because of cooling water again by internal rotor.

Purpose of design of the present utility model, be to adopt the cylinder body of vane rotor and interior garden globoidal structure to be sealed and matched, and utilize the compression autoignition principle of burning mixture, be designed to admission, compression, combustion stroke, the four-journey compression ignition RC engine of exhaust, be fit to the eccentric oil-pressing pump of moving vane through spring oil injecting nozzle injected fuel in the motor air chamber, and the water of water tank directly cools off the inner loop of cylinder body and rotor by water jacket, can improve the working life of mechanical efficiency and rotor, parameter difference according to use occasion, the rotor revolution of motor is moving a week all to have power stroke 2-4 time, and has horsepower greatly, in light weight, volume is little, long service life and fuel-saving advantage.

The cylinder body inner headed face of this motor is that the upper left of a concentric cylindrical cavity and 2 circumscribed circular arc chamber formations is admission---pressing chamber, the bottom right is a combustion stroke---the inner arc surface shape chamber of exhaust chamber, the rotor end face has configuration blade in the concane gap, all there is a pressure spring that blade can be radially slided between them, engine crankshaft and oil-pressing pump axle all are connected on the shaft axis, when Starter drives the engine crankshaft rotation, driving oil-pressing pump simultaneously rotates, oil-pressing pump sprays into the motor air chamber by the spring oil injecting nozzle with fuel oil, rotor blade is under acting force of the spring, hold out against the transfiguration product space of cambered surface slipper seal formation upper left air chamber in garden in the cylinder body, air-breathing to flammable mixing, the blade in back follows closely and compresses, the compression stroke section that blade is brought the position, lower-left into the rotor rotation, burning mixture is compressed in the firing chamber in the rotor top, blade conceals in the rotor, at this moment inflammable gas is subjected to high compression spontaneous combustion afterwards, and in the indoor further burning of combustion stroke, combustion vapour high-temperature high-pressure is impacted last the blade movement work done of expanding, and each blade on the engine rotor all plays double action suction vapour---compression in the rotor rotational slide, work done---exhaust, the rotation of rotor drives the engine crankshaft outputting power.

Owing to adopt such scheme, the compression ignition RC engine that manufactures and designs, just can be with eccentric moving vane oil-pressing pump, suck the fuel oil in the fuel tank, form the vaporific motor that enters through the adjusting of pressurization by the spring oil injecting nozzle and inhale steam chest, through the air-breathing compression and combustion of rotor blade, High Temperature High Pressure combustion temperature more than 1500 ℃ in the working stroke chamber, pressure 1Mpa/Cm ²Above expansion combustion gas promotes the vane rotor rotation, and drives the outside outputting power of engine shaft.The cooling water of motor passes through internal rotor from water tank to left water jacket cooling hole absorbs after the heat of cylinder body and rotor, flow into right water jacket and return water tank, thereby favorable cooling effect is arranged, and hold out against with Stamping Steel Ribbon link block and Spring pad between rotor blade and the sealing plate cylinder body and carry out good motive sealing, motor utilizes the compression autoignition principle of gasoline and air mixing, cancel its ignition system, it is simplified the structure.
