The invention discloses an engine combustion device provided with a variable separation combustion chamber. The engine combustion device provided with the variable separation combustion chamber comprises an oil atomizer, an oil cylinder cover, a gas sealing ring, an engine oil sealing ring, a sparking plug, an air cylinder body and a piston. A round-shaped groove is arranged at the bottom of the oil cylinder cover, the oil atomizer and the sparking plug are fixedly installed on the oil cylinder cover, a nozzle of the oil atomizer and the head portion of the sparking plug are arranged in the round-shaped groove at the bottom of the oil cylinder cover, the piston is arranged in a central through hole of the air cylinder body, a round-shaped protrusion is arranged on the top of the piston, and a central axis of the round-shaped protrusion aligns at a central axis of the round-shaped groove of the bottom of the oil cylinder cover. According to the engine combustion device provided with the variable separation combustion chamber, an oil atomizer secondary injection rule is used, through upward moving of the piston, the combustion chamber is separated automatically, dense gas mixture with even density is enabled to be formed in a middle region, when the sparking plug is lit, combustion is instantly finished, and heat efficiency is high. Through downward moving of the piston, flame jet of the middle region is used for lighting lean gas mixture in a non-combustion area under a high-pressure state, flame propagation velocity is extremely high, and end of combustion is quick.
Description
Technical field
The present invention relates to a kind of firing unit, relate in particular to a kind of engine combustion device with variable separation chamber.
Background technique
Existing engine technology, in the firing chamber, mixed gas is inhomogeneous, and the plug ignition velocity of propagation of flame is fast not, causes burning insufficient, even produces engine knock and deflagration phenomenon; Make burning produce a lot of pollution products, as nitrogen oxide, particulate matter etc.; In order to reach even mixed gas and to improve combustion efficiency as far as possible, the technology of employing has the in-cylinder direct injection technology, secondary injection technology etc., but the effect of improving is not fully up to expectations.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of engine combustion device with variable separation chamber is provided, the present invention is by secondary injection and separation chamber, mixture strength inequality and the slow-footed shortcoming of combustion flame propagation when effectively solving petrol engine combustion, can optimize the combustion position of petrol engine, reduce discharging; This device is simple, and is stable.
The objective of the invention is to realize by following technological scheme: a kind of engine combustion device with variable separation chamber comprises: oil sprayer, cylinder head, gas sealing ring, machine oil seal ring, spark plug, cylinder block and piston; Wherein, described cylinder head is fixedly mounted on cylinder block, and the bottom of cylinder head has a circular groove, and oil sprayer and spark plug are fixedly mounted on cylinder head, and the head of the nozzle of oil sprayer and spark plug is placed in the circular groove of cylinder head bottom.Piston is placed in the central through bore of cylinder block, and the top of piston has a circular protrusions, and the central axis of the circular groove of the central axis of its circular protrusions and cylinder head bottom aligns, and circular protrusions 3 matches with the circular groove of cylinder head 2 bottoms.Gas sealing ring and machine oil seal ring are arranged on the excircle of piston, and contact with the cylinder block inwall.
The invention has the beneficial effects as follows:
1, utilize oil sprayer secondary injection rule, by piston stroking upward, the automatic separation firing chamber makes to form the uniform rich mixture of concentration in zone line, and during spark ignitor, instancy of combustion is completed, burning fully, the thermal efficiency is high.
2, the expansion acting stage, by descent of piston, under high pressure conditions, utilize the flame of zone line to spray to light the not weak mixture in combustion zone, velocity of propagation of flame is exceedingly fast, and burning finishes fast and sufficient combustion.

In figure: oil sprayer 1, cylinder head 2, circular protrusions 3, gas sealing ring 4, machine oil seal ring 5, spark plug 6, cylinder block 7, piston 8.
Embodiment
The below describes the present invention with reference to the accompanying drawings in detail, and it is more obvious that purpose of the present invention and effect will become.
As shown in Figure 1, engine combustion device of the present invention comprises: oil sprayer 1, cylinder head 2, gas sealing ring 4, machine oil seal ring 5, spark plug 6, cylinder block 7, piston 8.
As shown in Figure 2, working procedure of the present invention is as follows: the up compression stage of piston 8, and the oil sprayer 6 pre-oil spouts of beginning form rarer mixed combustible gas in the firing chamber, when piston 8 is up to upper solstice, circular protrusions 3 enters in the circular groove of cylinder head 2, and the firing chamber is divided into two zones, and this moment, oil sprayer 6 main jets were oily, in the zone of cylinder head 2 bottom circular grooves, formed denseer inflammable mixture, because area of space is little, concentration is more even; Spark plug 1 igniting this moment, dense inflammable mixture burns rapidly, and flame moment is full of whole zone, sufficient combustion, pressure moment raises, and pushing piston 8 is descending; In the descending process of piston 8, the indoor flame of intermediate combustion is area spray towards periphery, lights weak mixture.Different from the flame propagation mode of traditional petrol engine Flame front, under the state of intermediate combustion chamber high pressure, flame sprays velocity of propagation and is exceedingly fast, can instantaneous ignition weak mixture in the neighboring area, make burning fully, the generation of reduction pollution products.
As shown in Figure 3, the heat release curve of apparatus of the present invention is compared with the heat release curve of uniform-charge Otto-engine, and difference is in particular in: the heat release curve of apparatus of the present invention, and there are obvious little crest and trough to occur, reason is burning and the expansion of intermediate combustion chamber; Thereafter flame sprays and to light the weak mixture zone, and in cylinder, heat release curve raises fast, and the rate of heat release peak value is larger, and burning finishes sooner, and the thermal efficiency is higher.
As shown in Figure 4, the heat release percentage curve of apparatus of the present invention is compared with the heat release percentage curve of uniform-charge Otto-engine, and difference is in particular in: the heat release percentage curve of apparatus of the present invention, initial ramp rate is faster, heat release is morning more, and heat release percentage reaches maximum value sooner, and combustion thermal efficiency is higher.
