Abstract
The utility model discloses a parallel-connection crankshaft engine, belonging to the fields of machines and thermal power. In order to overcome the defects of low load rate, low efficiency and high fuel waste of the traditional engine and solve the problem of energy loss of a closed air cylinder due to crankshaft rotation in some inventions, the utility model provides the parallel-connection crankshaft engine, in which each air cylinder or every two air cylinders is/are provided with a crankshaft. Each crankshaft is located at the lower part of each air cylinder body and is vertical to the longitudinal direction of each cylinder body. Each crankshaft is connected with a gear or a chain wheel together through a directional clutch. The gears or the chain wheels are mutually meshed to realize the mutual power transmission among the crankshafts. When the engine works, the number of the air cylinders participating the work can be determined according to the magnitude of a load, and the crankshafts of the non-working air cylinders can be stopped in running. Accordingly, not only is the load rate of the working air cylinders increased, but also the energy loss of the non-working air cylinders is reduced, so that the efficiency of the engine is increased.
Description
Technical field
The present invention relates to a kind of motor of parallel crank-axle, belong to machinery, thermal power field.
Background technique
At present, the widest motor of known application face is a conventional engine, and it all has application on apparatuss of transport such as automobile, train, steamer.It is made up of connecting rod, distribution device, cooling system, fuel supply system, ignition system, lubrication system etc.Experiment shows that the peak efficiency of petrol engine is about 30%, and the peak efficiency of diesel engine is about 40%.Peak efficiency is to occur in motor near under the situation of operating at full capacity, and most motor (as: motor of using on the apparatuss of transport such as automobile, train, steamer) is operated in the most of the time under the operating mode of medium and small load.Under medium and small load, the efficient of motor will cause the waste of a large amount of fuel well below its peak efficiency.The invention that has has taked to close the measure of cylinder control in order to improve motor Rate of load condensate during low speed driving in apparatuss of transport such as automobile, train, steamer, makes PSD Partical Shut Down.Close cylinder control, have plenty of through stopping oil spout and realize having plenty of, close the inlet and exhaust valve of some cylinder and realize through variable valve actuating mechanism.Though this Rate of load condensate of closing cylinder control raising working cylinder, inoperative cylinder piston, bent axle still cause the energy loss of friction and intake and exhaust at high speed operation.
Summary of the invention
Low in order to overcome the available engine Rate of load condensate, efficient is low, the energy loss problem of shifter cylinder in big and some invention of waste of fuel, and the present invention provides a kind of motor, improves the Rate of load condensate of working cylinder equally through the partial cylinders in killing engine.Different with other inventions is that bent axle, the piston of institute's shifter cylinder do not rerun in the present invention, have avoided energy loss.
The technical solution adopted for the present invention to solve the technical problems is: what the present invention was different with traditional multicylinder engine is: traditional multicylinder engine has only a bent axle.The present invention works alone each cylinder of multicylinder engine to adopt the many bent axles that are parallel to each other, and promptly each or two cylinders have a bent axle.Bent axle is vertical vertical cylinder block bottom and cylinder body.Every bent axle links together through directional clutch and gear or sprocket wheel.Directional clutch is a kind of special clutch, makes between bent axle and the gear to have only unique position to combine, and guaranteeing the phase relationship when rotating between each bar Quzhou, thereby makes engine running steady.Gear or sprocket wheel link to each other with bent axle through directional clutch on the one hand, are meshing with each other on the other hand to realize the mutual transmission of power between the bent axle, and store kinetic energy plays flywheel when engine rotation simultaneously.Each cylinder of tradition multicylinder engine distribution cam axle is shared.The present invention can also can be mated every bent axle with bent axle and join a camshaft as conventional engines.Other position fundamental sum conventional engines are identical.During engine operation, load is bigger if desired, and all cylinders of motor are all devoted oneself to work, and the power of each bent axle is through the output that pools together of directional clutch, gear or sprocket wheel; It is less to load if desired, and computer can stop the igniting and the oil spout of partial cylinders according to the size of required load, and the directional clutch on this bent axle is separated, so this part cylinder quits work, and bent axle, piston shut down; If required load increases once again, computer can be resumed work by the control section cylinder.That is to say that computer can be according to the work quantity of cylinder of the size of required load control.
The invention has the beneficial effects as follows,, not only improved the Rate of load condensate of motor, improved efficient, and reduced the energy loss that friction causes, thereby reduced oil consumption through stopping the running of multicylinder engine institute shifter cylinder bent axle piston.
Description of drawings
Fig. 1 is first embodiment's of parallel crank-axle engine a structure principle chart
Fig. 2 is the A-A sectional view of Fig. 1
Fig. 3 is second embodiment's of parallel crank-axle engine a structure principle chart
Mark among the figure: 1. cylinder head, 2. horizontal camshaft, 3. directional clutch and gear, 4. bent axle, 5. cylinder block 6. goes up timing belt pulley, and 7. Timing Belt 8. descends timing belt pulley, the 9. vertical camshaft of putting.
Embodiment
Embodiment 1: be example with the four cylinder engine, as shown in Figure 1, each cylinder all has bent axle (4) and the horizontal camshaft (2) of oneself.Directional clutch and gear (3) all are housed on the every bent axle (4).Other positions and common engine are basic identical.When needs output smaller power; Computer can be controlled a cylinder operation, though the gear of other cylinders rotates because directional clutch separates, bent axle (4) and camshaft (2) do not rotate; Do not work, idle like this cylinder does not have energy consumption basically.The Rate of load condensate of working cylinder is higher simultaneously, and efficient is higher, so oil consumption rate is lower.When the output of needs motor was more high-power, computer can be controlled the quantity that directional clutch combines to increase working cylinder.No matter that is to say that under what operating mode, the working cylinder of motor can both obtain bigger Rate of load condensate.
Embodiment 2: be example with the four cylinder engine, as shown in Figure 3, different is four shared vertical camshafts (9) of putting of cylinder with embodiment 1.Motor is simple in structure like this, but the valve of working cylinder does not have any energy losses still in action.
Claims (1)
1. parallel crank-axle engine; Form by connecting rod, distribution device, cooling system, fuel supply system, ignition system, lubrication system etc.; It is characterized in that: multicylinder engine adopts the many bent axles that are parallel to each other; Be that each or two cylinders have a bent axle, vertical vertical at cylinder block bottom and cylinder body, and link to each other through directional clutch, gear or sprocket wheel.
