Description
The utility model relates to internal-combustion engine technology, and a kind of vapour bavin reciprocating piston double action four-stroke ic engine is provided especially.
Internal-combustion engine is that fuel is burnt at machine intimate, and the heat energy of emitting directly is converted to the dynamic power machine of power, and is the most general with conventional engine.Wide, the supporting convenience of its thermal efficiency height, power and speed range, mobility are good.But since coming out the sixties in 19th century, though through constantly improvement and perfect, the raising of performance is not very big, and particularly 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 motor overwhelming majority as automobile power is that employing gasoline or light diesel are the four-stroke stroke piston combustion engine of fuel at present, the petrol engine discharge capacity is less than 2.5 liters in-line four cylinder commonly used, horizontal opposed cylinder, minority has V-type 6 cylinders or 8 cylinders, the diesel engine majority is 6 cylinders in upright arrangement, then uses V-type more than 180 kilowatts.
The purpose of this utility model is to provide a kind of dual-purpose gasoline and diesel oil four-stroke internal combustion engine, its compact structure, and unit weight output power height, fuel consumption is low, is particularly suitable for as automobile power machinery.The utility model provides a kind of dual-purpose gasoline and diesel oil four-stroke internal combustion engine, form by connecting rod, body, distribution device, oil supply system, lubrication system, cooling system, starting arrangement, connecting rod is made of piston set, connection rod set, bent axle and flywheel, the cylinder that cylinder sleeve is housed is installed in the body, it is characterized in that: this explosive motor has two cover crank linkage mechanisms, and two cover crank linkage mechanisms connect by 3,5 or 7 driving gears (5); Installing two opposed pistons (4) in the cylinder of every single cylinder (3), two pistons (4) have identical phase place; The inlet and exhaust valve of distribution device (6) is arranged at the sidewall at cylinder (3) middle part, adopts four-stroke intake and exhaust mode.
The end face of piston described in the utility model (4) can be the concave structure that sink; Be placed in the symmetrically both sides of cylinder (3) of the inlet and exhaust valve of described distribution device (6) 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 (6) partly can be protruded in the cylinder (3), the corresponding site of piston (4) is provided with corresponding sagging step.
The number of dual-purpose gasoline and diesel oil four-stroke internal combustion engine cylinder provided by the utility model (3) can be 2,4,6 or 8.Inlet and exhaust valve described in the utility model (6) can be vertical also can be horizontal type.
The dual-purpose gasoline and diesel oil four-stroke internal combustion engine that the utility model provides has following advantage:
1, structural design compactness is compared with in-line arrangement or V-type cylinder engine, and when output power was identical, the weight of himself was the lightest, i.e. the output power height of unit weight;
2, increased a bent axle that can be used for exporting, the axle of each driving gear also can be used as output shaft, thereby has increased the alternative of output shaft; Again because its volume is little, be easy to put simultaneously, improved the layout design rationality of automobile.
3, owing to increased some driving gears, thereby improve the balance of motor, made motor have bigger moment of torsion and potential energy reserve factor simultaneously, promptly improved the maximum output of motor.
4, compare with in-line arrangement or V-type cylinder engine, under identical cylinder volume condition, reduced the number of inlet and exhaust valve, the effective rate of utilization of firing chamber is improved, thereby improved the thermal efficiency.
5, owing to adopt dual ignition, make fuel evenly burning fully fast in the firing chamber when improving fuel economy, can also prevent the generation of disconnected cylinder phenomenon.
6, the end face of piston adopts the design of concave surface, can produce mandatory eddy current when air inlet and compression, and gas is fully mixed, and fully burning when improving fuel economy, has also reduced exhaust gas discharging.
The utility model volume is little in light weight in a word, compares with existing motor car engine and has improved mechanical efficiency, has improved combustion process, has reduced radiation loss, has reduced fuel consume.Below by embodiment in detail the utility model is described in detail.

Embodiment 1
Dual-purpose gasoline and diesel oil four-stroke internal combustion engine has two cylinders (3) as shown in Figure 1, four pistons (4); Per two pistons (4) constitute a cover crank linkage mechanism with its connecting rod (2), bent axle (1), two cover crank linkage mechanisms are joined by 5 driving gears (5), two cover crank linkage mechanisms are staggered relatively in the both sides of two cylinders (3), belong to two pistons (4) in the connecting rod in each cylinder (3) respectively the top is placed, have identical phase place.Distribution device is seen accompanying drawing 1, and 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.That is: 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.
As shown in Figure 3, difference from Example 1 is, the be placed in both sides of cylinder (3) of inlet and exhaust valve (6) are provided with two spark plugs, and the end face of piston is designed to the structure of concave surface.
As shown in Figure 4, difference from Example 2 is that inlet and exhaust valve (6) partly embeds in the cylinder (3), and in order to prevent the collision of piston (4) and cylinder (3), the end face of piston (4) is provided with the step of a phase lower recess, sees accompanying drawing 5.
Difference from Example 3 is that inlet and exhaust valve (6) is a vertical structure, sees accompanying drawing 6,7.
