Abstract
The utility model relates to an internal-combustion engine with a gas-filled cylinder. The fuel gas cylinder of the internal-combustion engine with a gas-filled cylinder is matched with a gas-filled auxiliary cylinder. When a fuel gas piston downwards moves, gas is filled from the gas-filled cylinder to the fuel gas cylinder. The lower dead point position of the fuel gas piston of the fuel gas cylinder is provided with an exhaust opening. A crank shaft rotates one turn, and the fuel gas piston completes two working cycles of gas change, compression, combustion, and expansion. The internal-combustion engine with a gas-filled cylinder is characterized in that the internal-combustion engine with a gas-filled cylinder has high gas change efficiency and strong inflation capability. The internal-combustion engine with a gas-filled cylinder has the advantages of high efficiency, energy saving, low exhaust pollution, simple structure, a few of parts, etc. The internal-combustion engine with a gas-filled cylinder can be designed into a diesel engine or a gasoline engine.
Description
The utility model belongs to mechanical engineering prime mover.
At present, the two stroke IC engine of extensive use adopts crankcase gas or Roots pump scavenging mode to take a breath.Quartastroke engine adopts the self-priming mode to take a breath, and all exists scavenging efficiency low, the air-breathing ability difference to topic.Therefore limited the raising of the thermal efficiency of internal-combustion engine.Also there be the bad of fuel combustion in two stroke IC engine in addition, the shortcoming that exhaust pollution is big.Also there is the high shortcoming of complex structure manufacture cost in quartastroke engine.
The purpose of this utility model be to propose the strong characteristics of the high air-breathing ability of a kind of scavenging efficiency advantages such as to have an energy-efficient exhaust pollution low, and part simple in structure is few have an inflating cylinder internal-combustion engine type.
The utility model is made up of crankcase, gas cylinder, inflating cylinder, gas piston, inflation piston, combustion gas cylinder cap, inflation cylinder cap, gear shaft, connecting rod, union body, bent axle and lubricated, distribution, distribution, exhaust, oil supply system and starting arrangement.Its main points are that the gas piston that has the tooth bar of horizontal parallel layout and inflation piston are contained in the gas cylinder and inflating cylinder on the crankcase, two-piston tooth bar tooth is done slide relative by the gear shaft one end tooth engagement of centre, the connecting rod tooth bar tooth engagement driving that gear shaft the other end tooth is connected with bent axle in the crankcase by union body, the gear shaft top be gas cylinder, following is inflating cylinder and corresponding mutually, gas cylinder is in the lower dead point position place at the gas piston two ends and is provided with relief opening, inflating cylinder is covered with intakeport and valve and crosses gas port, gas cylinder is covered with valve and oil sprayer or spark plug mounting hole, valve is equipped with antagonistic spring, is enclosed on the valve seat under spring action during no negative air pressure in cylinder.Inflation cylinder cap and combustion gas cylinder cap are fixed on the crankcase with screw with inflating cylinder and gas cylinder.
Working principle: under of the gas effect of gas piston one end in a last work cycle burning expansion, slide to lower dead centre from upper dead center, inflation piston correspondence slides to live gas that upper dead center sucks last work cycle or mixed gas and crosses the valve that gas port and combustion gas cylinder cap open from the inflation cylinder cap under gas pressure and fill in the gas cylinder, simultaneously the relief opening cleaning of the waste gas after the gas cylinder internal combustion from opening, when gas piston one end backhaul is compressed to upper dead center, promptly finished a work cycle, gas piston comes and goes and slides once, each ignition of two ends is (diesel engine compression ignite once, the petrol engine spark ignitor), finished the burning expansion ventilation cycle twice, by gear shaft and connecting rod transmission, crankshaft rotating one is changeed.
The utility model gas cylinder is taken a breath by big volume inflating cylinder inflation mode, characteristics are that the high air-breathing ability of ventilation effect is strong, by the charging volume of rationally definite inflating cylinder cylinder diameter formation and the compression ratio of gas cylinder, all can obtain fabulous strengthening effect and thermal efficiency effect to combustion different fuel type.The utility model is suitable to be designed to diesel engine or petrol engine, can be applicable on automobile, the tractor and reaches mine, forestry, oil and construction engineering etc. mechanically.
The utility model advantage mainly is that scavenging efficiency height, air-breathing ability are strong, and energy-efficient exhaust pollution is low, the few low cost of manufacture of part simple in structure.
Below in conjunction with accompanying drawing the utility model most preferred embodiment is done further narration.
