The gasoline engine combustion chamber comprises a closed space formed by a cylinder body, a piston, a cylinder cover, a spark plug, an exhaust valve and an inlet valve, wherein the piston is arranged in the cylinder body; the cylinder cover is arranged at the upper end of the cylinder body; the spark plug, the exhaust valve and the inlet valve is arranged on the cylinder cover; the upper end of the piston is provided with a boss at the part corresponding to the spark plug; the boss is provided with an avoidance concave pit at the part corresponding to the spark plug; a main combustion area is formed between the periphery of the boss and the inner wall of the cylinder cover; a pre-combustion area is formed between the boss and the inner wall of the cylinder cover; a pre-combustion chamber is formed in the avoidance concave pit. After the gasoline engine combustion chamber with the function of partition combustion is adopted, mixed gas can fully burn, so that the available compression ratio of the complete machine is improved, and the oil consumption and the emission are reduced; the gasoline engine combustion chamber is in accordance with the requirements of energy conservation and emission reduction of China, and the power performance and the economy of a gasoline engine are improved.
Description
Technical field
The utility model relates to a kind of combustion chamber of petrol engine of subregion burning, belongs to technical field of internal combustion engines.
Background technique
The firing chamber of petrol engine plays vital effect in whole combustion process, the firing chamber of existing petrol engine mainly contains: multiple several shapes such as hemispherical combustion chamber, fluffy shape firing chamber, wedge-section combustion chamber, although the processing of above-mentioned firing chamber is simple, become to produce cost low, hot area is little, but in mixture combustion process, easily produce " detonation ", limited the raising of petrol engine compression ratio, thereby reduce power character, Economy and the emission performance of petrol engine.
Model utility content
The purpose of this utility model is the combustion chamber of petrol engine for a kind of subregion burning is provided; In this firing chamber, be provided with precombustion chamber, San Ge region, He Zhu zone of combustion, precombustion district, after plug ignition, in precombustion chamber, forming Huo Hebingxiang precombustion district spreads, propagate by Xiang Zhu zone of combustion, precombustion district, can guarantee that like this mixed gas in firing chamber can reliably put so and smooth combustion, really realized first slow after anxious Combustion Release Heat; Because the rate of pressure rise at the initial stage of catching fire is low, therefore reduce the negative work producing because of gaseous combustion in ignition advance angle, thereby made engine operation softer, suppress the generation of " detonation " phenomenon; This firing chamber can make mixed gas fully burn, and has improved the available compression ratio of complete machine, has reduced oil consumption and discharge, meets national energy-saving and reduces discharging when requirement, and the power character of petrol engine and Economy are improved.
In order to achieve the above object, the utility model is realized by following technological means:
A kind of combustion chamber of petrol engine of subregion burning, it is by cylinder block, piston, cylinder head, spark plug, the enclosed space that exhaust valve and intake valve form, in cylinder block, be provided with piston, the upper end of cylinder block is provided with cylinder head, in cylinder head, be provided with spark plug, exhaust valve and intake valve, it is characterized in that: the upper end of piston and spark plug corresponding part are provided with boss, on boss, be provided with and dodge pit with spark plug corresponding part, between boss surrounding and cylinder head inwall, form main zone of combustion, between boss and cylinder head inwall, form precombustion district, the described interior precombustion chamber that forms of pit of dodging.
On described boss, be provided with and dodge pit with exhaust valve and intake valve corresponding section.
The utility model mainly has following beneficial effect:
1, in this firing chamber, be provided with precombustion chamber, San Ge region, He Zhu zone of combustion, precombustion district, after plug ignition, in precombustion chamber, forming Huo Hebingxiang precombustion district spreads, propagate by Xiang Zhu zone of combustion, precombustion district, can guarantee that like this mixed gas in firing chamber can reliably put so and smooth combustion, really realized first slow after anxious Combustion Release Heat.
2, because the rate of pressure rise at the initial stage of catching fire is low, therefore reduce the negative work producing because of gaseous combustion in ignition advance angle, thereby made engine operation softer, suppress the generation of " detonation " phenomenon.
3, this firing chamber can make mixed gas fully burn, and has improved the available compression ratio of complete machine, has reduced oil consumption and discharge, meets national energy-saving and reduces discharging when requirement, and the power character of petrol engine and Economy are improved.

Embodiment
Embodiment
As shown in Figure 1 and Figure 2, a kind of combustion chamber of petrol engine of subregion burning, the enclosed space that it is made up of cylinder block 1, piston 2, cylinder head 3, spark plug 7, exhaust valve 9 and intake valve 10, in cylinder block 1, be provided with piston 2, the upper end of cylinder block 1 is provided with cylinder head 3, is provided with spark plug 7, exhaust valve 9 and intake valve 10 in cylinder head 3.
As shown in Figure 1 and Figure 2, the upper end of piston 2 and spark plug 7 corresponding parts are provided with boss 5, on boss 5, be provided with and dodge pit 8 with spark plug 7 corresponding parts, between boss 5 surroundings and cylinder head 3 inwalls, form main zone of combustion 4, between boss 5 and cylinder head 3 inwalls, form precombustion district 6, described in dodge the interior formation precombustion chamber of pit 8.
As shown in Figure 2, according to the movement interference situation of valve and piston, on described boss 5, be also provided with and dodge pit with exhaust valve 9 and intake valve 10 corresponding sections.
As shown in Figure 1, working principle is: after spark plug 7 igniting, flame forms fiery core dodging in the precombustion chamber that pit 8 forms, and spread to 6 places of precombustion district, then light the mixed gas in main zone of combustion 4 by precombustion district 6, can make like this law of heat release of firing chamber meet first slow rear anxious principle, avoid the generation of " detonation " phenomenon, be conducive to improve the compression ratio of petrol engine.
