Abstract
An engine with two crank-connecting rod mechanisms is composed of two crank-connecting rod mechanisms, main body, air distribution unit, oil supply system, lubricating system, cooling system and starter. Each crank-connecting rod mechanism consists of piston, connecting rod, crankshaft and flywheel. Each cylinder has two pistons arranged opposite. Its advantages are compact structure, high output power and low oil consumption.
Description
Technical field
The present invention relates to a kind of motor, especially a kind of motor with two cover crank linkage mechanisms.
Background technique
The motor of prior art, the effective thermal efficiency maximum only reaches 0.46.Automobile is mainly used in transportation, requires to have that weight is few, volume is little, fuel saving, power plant that adaptability is good and reliability and durability.The petrol engine discharge capacity is less than 2.5 liters in-line four cylinder commonly used, horizontal opposed cylinder, and minority has V-type 6 cylinders or 8 cylinders, and the diesel engine majority is 6 cylinders in upright arrangement, then uses V-type more than 180 kilowatts.
Summary of the invention
Technical problem to be solved by this invention provides a kind of motor with two cover crank linkage mechanisms, its compact structure, and unit weight output power height, fuel consumption is low.
The technical solution adopted for the present invention to solve the technical problems is: it is by connecting rod, body, distribution device, oil supply system, lubrication system, cooling system, starting arrangement is formed, connecting rod is by piston set, connection rod set, bent axle and flywheel constitute, the cylinder that cylinder sleeve is housed is installed in the body, this motor has two cover crank linkage mechanisms, two cover crank linkage mechanisms are by 3,5 or 7 driving gears connect, two opposed pistons of installing in the cylinder of every single cylinder, two pistons have identical phase place, the inlet and exhaust valve of distribution device is arranged at the sidewall at cylinder middle part, adopts four-stroke intake and exhaust mode.Be placed in the symmetrically both sides of cylinder of the concave structure that the end face of described piston can be sink, the inlet and exhaust valve of described distribution device form the double combustion chamber that is interconnected, and are equiped with two spark plugs by a single line control in the double combustion chamber respectively.In order further to improve the thermal efficiency, inlet and exhaust valve partly can be protruded in the cylinder, the corresponding site of piston is provided with corresponding sagging step.The number of engine cylinder can be 2,4,6 or 8.Described inlet and exhaust valve can be vertical also can be horizontal type.
The invention has the beneficial effects as follows: improved mechanical efficiency, improved combustion process, reduced radiation loss, reduced fuel consume.
Description of drawings
Fig. 1 is the engine structure schematic representation with two cover crank linkage mechanisms.
Fig. 2 is second kind of distribution device principle schematic with motor of two cover crank linkage mechanisms.
Embodiment
As shown in the figure, motor with two cover crank linkage mechanisms, have two cylinders 3, four pistons 4, per two pistons 4 constitute a cover crank linkage mechanism with its connecting rod 2, bent axle 1, and two cover crank linkage mechanisms are joined by 5 driving gears 5, and two cover crank linkage mechanisms are staggered relatively in the both sides of two cylinders 3, belong to 4 pairs of tops of two pistons in the connecting rod in each cylinder 3 respectively and place, have identical phase place.Inlet and exhaust valve 6 is arranged on the middle part sidewall of cylinder 3, and the common quartastroke engine of its distribution process is the same.The inlet and outlet door is not opening and closing when last bottom dead center position, but suitably opening and closing in advance.Intake valve is promptly to open in budc, and intake valve has bigger aperture during with the assurance descent of piston, can reduce flow resistance like this when intake process begins, and reduces the air-breathing merit that consumes, and also can pour more fresh momentum simultaneously.When piston ran to lower dead center in intake process, because air-flow inertia, fresh momentum can continue to charge into cylinder, so make intake valve in late release after bottom dead center.Exhaust valve is also opened Before Bottom Dead Center in advance, promptly just begin exhaust in the expansion stroke rear section, this is in order to utilize gaseous-pressure higher in the cylinder to make waste gas flow out cylinder automatically, thereby make piston from lower dead center when top dead center moves in the cylinder gas pressure low, to reduce piston waste gas is squeezed the merit that cylinder is consumed.The purpose that exhaust valve After Top Center cuts out is to utilize the inertia of exhaust air flow, makes the cleaner of the interior residual gas eliminating of cylinder.Because exhaust valve late release and intake valve is opened in advance just has an end time inlet and outlet door to open simultaneously near top dead center, there is the fresh momentum of a small part to charge into by intake valve, to discharge by exhaust valve, countercylinder has carried out scavenging.
