Abstract
The utility model discloses a high-pressure common rail oil injection vortex type combustion system. According to the structure of the system, a high-pressure common rail oil injector is connected with a high-pressure common rail pump; the high-pressure common rail oil injector is assembled together with a cylinder cover; and an oil injection nozzle of the high-pressure common rail oil injector is arranged above a vortex type combustion chamber. Atomized fuel oil is injected into a main combustion chamber of a diesel to work through a main injection hole and a secondary injection hole of the vortex type combustion chamber. The high-pressure common rail system is adopted in a vortex chamber engine; and a special combustion mode is formed by optimized matching of an oil injection pump, an electronic control oil injector, an engine vortex chamber and an air inlet passage of the high-pressure common rail system. The oil injection mode of the high-pressure common rail diesel is applied to the vortex chamber engine, and the vortex chamber engine meets the requirement of national IV emission. The system is verified in a CYQD32 vortex chamber engine, the dynamic property and the economical efficiency of the engine meet the design requirements and are improved greatly compared with the conventional engine, and the vortex chamber engine is produced in batch nowadays.
Description
Technical field:
The utility model belongs to DENG burning structure technology, is specifically related to a kind of improvement of DENG injection system device.
Background technique:
The technician of engine building knows that all turbulence-chamber engine adopts axle type single hole oil sprayer mostly, and injection pressure is lower, and fuel-oil atmozation is relatively poor, can not realize control is at regular time and quantity carried out in the injection of fuel oil.And the oil spout mode of high pressure co-rail diesel machine can be controlled the injection of fuel oil, is comparatively advanced fuel feeding pattern.But this electric-controlled fuel injector only is fit to direct injection ic engine, and is not suitable for turbulence-chamber engine, so the high-pressure common rail oil-fired system mostly is applied on the direct injection ic engine.How the oil spout mode with the high pressure co-rail diesel machine also is applicable to turbulence-chamber engine, is the research of technique problem of the sector always.Because turbulence-chamber engine still has market widely at present, and the short time can not withdraw from.So high pressure common rail injector both had been fit to high-pressure common rail; Can also satisfy the requirement of turbulence-chamber engine, for the upgrading of turbulence-chamber engine combustion technology, significant; If but make the high-pressure common rail oil-fired system into direct spray type (motor); Need design parts such as cylinder cap, piston, bent axle and connecting rod again, input cost is high, and the construction cycle is also long.The utility model proposes high pressure oil pump, electric-controlled fuel injector and motor vortex chamber and the intake duct optimization of matching through high pressure co-rail system; Form special combustion manner; Can the oil spout mode of high pressure co-rail diesel machine be applicable to turbulence-chamber engine, and reach the requirement of state IV discharging.
Summary of the invention:
To the problems referred to above, the purpose of the utility model provides a kind of vortex type combustion system device of high-pressure common rail oil spout.
Describe below in conjunction with the know-why of accompanying drawing the utility model.The vortex type combustion system of high-pressure common rail oil spout comprises: cylinder head, high-pressure common rail oil pump, turbulence combustion chamber, high pressure common rail injector, main jet hole, secondary spray orifice and diesel engine main combustion chamber; Its technological scheme is that high pressure common rail injector is connected to the high-pressure common rail oil pump; High pressure common rail injector and cylinder head are fitted together, and the oil nozzle of high pressure common rail injector places the top, turbulence combustion chamber.Atomized fuel sprays into diesel engine main combustion chamber work by combustion through the main jet hole and the secondary spray orifice of turbulence combustion chamber.
The know-why of the utility model mainly is the oil spout mode that changes the turbulence combustion chamber; High pressure common rail injector is placed in the turbulence combustion chamber; The vortex chamber and the air flue of high oil pump, electric-controlled fuel injector and motor through high pressure co-rail system carry out matching Design, and turbulence-chamber engine is also realized fuel injection at regular time and quantity.
The characteristics and the beneficial effect of the utility model are: need not the connection of parts such as cylinder cap, piston, bent axle and connecting rod is designed again; Through high pressure oil pump, electric-controlled fuel injector and motor vortex chamber and intake duct optimization of matching to high pressure co-rail system; Form special combustion manner; Just can the oil spout mode of high pressure co-rail diesel machine be applicable to turbulence-chamber engine, and reach the requirement of state IV discharging.
Description of drawings:
Shown in accompanying drawing 1 be the theory structure sketch of the utility model.
Embodiment:
Below in conjunction with accompanying drawing and through embodiment the structure of the utility model is further described.The vortex type combustion system of high-pressure common rail oil spout, its structure are that high pressure common rail injector 1 is connected to high-pressure common rail oil pump 2, and high pressure common rail injector and cylinder head 3 are fitted together, and the oil nozzle of high pressure common rail injector places 4 tops, turbulence combustion chamber.Atomized fuel sprays into diesel engine main combustion chamber 7 work by combustion through the main jet hole 5 and the secondary spray orifice 6 of turbulence combustion chamber.The intake duct of cylinder head is oblique tangential intake duct.
The signal that high pressure common rail injector sends according to ECU (car load electric control unit), through the opening and closing of associated solenoid valve, with the fuel oil in the high pressure oil rail with the timing of the best, quantitatively and fuel injection rate spray in the vortex chamber in the cylinder head.The mixed gas that in the vortex chamber, does not fire, the diesel engine main combustion chamber that gets into piston top through main jet hole and secondary spray orifice is carried out secondary combustion.Because sufficient combustion, so NOx and PM discharge amount are all low than direct spray type.And the turbulence-chamber engine combustion noise is low; Common rail system all has superiority to engine emission and burning; Through the optimization of matching of turbulence-chamber engine and high pressure co-rail system, satisfy the requirement of motor state four Abgasgesetzs, Economy and power character also all are improved than conventional engines.
The utility model is verified enforcement on the CYQD32 swirl chamber diesel engine, engine power performance and Economy all meet design requirement, and all improve a lot than former motor, and emission level satisfies state IV requirement, produces in batches now.
