Abstract
The utility model relates to an internal combustion engine for national economy construction and production of industry and agriculture with the characteristics of high thermal efficiency and low environmental pollution. A working cycle completed by the cooperation of double cylinder via the improvement of the structure of the existing piston type internal combustion engine which has the characteristic that the working cycle is completed by single cylinder. The utility model has the advantages of constant-volume combustion, complete combustion, variable-volume expansion of combustion expansion gas, complete expansion work, and low energy consumption, low discharge, and low noise of the power circulation of the heater; petroleum resources are saved and environmental pollution is low.
Description
The motive force that the utility model relates to automotive industry, tractor, agricultural vehicle, boats and ships and the required usefulness of industrial and agricultural production provides.
Increasing along with the countries in the world automobile pollution, face the environmental pollution that the global energy reduces and is on the rise, people will propose higher requirement to the internal-combustion piston engine as automobile power and the use of other power at aspect its economic performance and minimizing atmospheric pollution aspect.Yet existing piston formula internal-combustion engine is desired to want to increase substantially fuel economy and is quite difficult and pays expensive cost with further reduction harmful exhaust discharge amount because the work cycle that determined by its basic structure has restricted hot merit conversion efficiency and toxic emission quality.The essential structure principle of existing piston formula internal-combustion engine is that the piston of tubular moves back and forth in the cylinder of tubular, the mixed combustion in cylinder of fuel and air, the combustion gas expanded by heating promotes piston and moves generation power, by crankshaft-link rod the mobile outputting power that rotatablely moves that changes into of piston.To be the firing chamber be positioned at the institute that has living space of institute more than the top dead center by piston-top surface to the feature of its fuel combustion work done forms, burning is to do to burn under the rapid condition of enlarged of high-speed motion combustion chamber volume at piston, the burning of inflammable gas limit, expand in the limit, not complete expansion and under the constant volume situation, discharging as yet, thus feature limits the raising and the harmful exhaust emission standard of existing motor fuel Economy.
The purpose of this utility model will provide exactly that a kind of oil consumption is low, the thermal efficiency is high, the high quality engine that atmospheric pollution is little, voice is little.
The utility model is the improvement to existing internal-combustion piston engine work cycle, it is characterized in that a work cycle that air inlet, compression, work done, four processes of exhaust are formed is finished by single cylinder to change into two cylinder cooperations and finish.Realized combustion gas work done complete expansion, fuel perfect combustion, thereby improved the effective thermal efficiency of internal-combustion engine has reduced fuel consumption, has reduced the harmful exhaust discharge amount, has reduced exhaust noise and has improved pollution to environment greatly.
Below in conjunction with accompanying drawing the utility model is further described, Fig. 1 is the utility model longitudinal sectional view.Pressure gas cylinder among Fig. 1 (3) and expansion cylinder (14) are embedded in the body (2), and pressure gas cylinder is directly identical through different heights with expansion cylinder, and the expansion cylinder swept volume ratio displacement of calming the anger is big about 1.5 times.Displacer and expansion piston are slidingly connected by connecting rod (15) and bent axle (1) crank throw, bent axle is contained in the main bearing in the body (2), cylinder head (12) is fitted on the last plane of body, firing chamber (7) is in cylinder head, revolution pressure valve (6) revolution gas valve (10) is installed in the both sides, firing chamber, pressure valve and pressure gas cylinder, the firing chamber communicates, gas valve and expansion cylinder, the firing chamber communicates, igniter plug (8) oil nozzle (9) is installed in top of combustion chamber, intake valve (5) is contained in and is positioned at pressure gas cylinder one side on the cylinder head, exhaust valve (11) is contained in expansion cylinder one side on the cylinder head, the relative displacer crank throw crank throw relative with expansion piston is positioned at the same side of crankshaft center line on the bent axle, opposite side configuration balancer weight, the displacer crank throw is than the leading 10-15 of expansion piston crank throw ° crank angle.
Its working principle of the utility model is: when two-piston from lower dead center intake valve, gas valve when top dead center moves close, exhaust valve, pressure valve open, at this moment be full of the interior ambient air of pressure gas cylinder along with the up of piston gradually reduces, form high-speed rotational by pressure valve and be pressed into the firing chamber, waste gas enters the external world by exhaust valve in the expansion cylinder simultaneously.At displacer during near top dead center, fuel oil sprays into the firing chamber with the air-flow of calming the anger and mixes the formation inflammable mixture with pressurized air, at this moment pressure valve is closed, the igniter plug igniting, inflammable mixture isochoric combustion in firing chamber independently, piston moves hysteresis 10-15 ° crank angle because the expansion piston ratio is calmed the anger, when expansion piston arrived top dead center, the mixed gas in the firing chamber is burning rapidly, forms high temperature and high pressure gas, at this moment gas valve is opened, exhaust valve closing, high temperature and high pressure gas expands rapidly by gas valve in the firing chamber, pours expansion cylinder and promotes the descending generation power of expansion piston, finish a work cycle, one week of crankshaft rotating.
