Abstract
The utility model relates to a stratified combustion device of a four-stroke gasoline engine, and aims to obtain good stratified combustion effect on the four-stroke gasoline engine and improve the economical efficiency of the gasoline engine. The present four-stroke gasoline engine includes a cylinder cover 3, an intake valve 1, a exhaust valve 2, a cylinder body 4, a piston 6, a spark plug 7 and other parts; on the basis of the present four-stroke gasoline engine, the utility model adds a second air inlet 5 and a second air inlet passage 8, wherein the second air inlet 5 is formed on the periphery of a cylinder hole of the cylinder body 4 and between a top dead center and a bottom dead center of the piston 6, and the second air inlet 5 and the second air inlet passage 8 are connected; and unsupercharged combustible gas mixture enters the cylinder through the intake valve 1, the supercharged gas mixture of air and exhaust gas enters the cylinder through the additionally arranged second air inlet passage 8 and the second air inlet 5 at the same time, the stratified charge is formed, and the gas mixture is ignited by the spark plug 7 to have stratified combustion.
Description
Technical field
The utility model relates to the combustion in IC engine technical field, specially refers to the layering burn device of four-stroke gasoline engine.
Background technique
In the prior art, stratified mixture combustion has separated type firing chamber stratified combustion and the cylinder inner high voltage directly sprays stratified combustion etc.These laminating combustion system complex structures; When middle or small load, combustion instability appears easily, and knocking combustion appears when loading greatly easily.
The model utility content
The utility model mainly provides a kind of device of four-stroke gasoline engine stratified mixture combustion.Its objective is in order on four-stroke gasoline engine, to obtain good stratified mixture combustion effect, improve the Economy of petrol engine.
The utility model four-stroke gasoline engine layering burn device as shown in Figure 1, its technological scheme is: improve on the existing four-stroke gasoline engine that comprises parts such as cylinder head 3, intake valve 1, exhaust valve 2, cylinder block 4, piston 6 and spark plug 7, add second suction port 5 and second intake duct 8; In the intake process, unsupercharged inflammable mixture enters cylinder by intake valve 1, second suction port 5 that is provided with on the air of supercharging simultaneously and the circumferential surface of mixed gas by cylinder block 4 cylinder holes of waste gas enters in the cylinder, form the inflammable mixture of concentration stratification, spark plug 7 is lighted denseer inflammable mixture, then forms stratified mixture combustion.
Description of drawings
Fig. 1 is the structural representation of the utility model four-stroke gasoline engine layering burn device.
Among the figure: 1 intake valve, 2 exhaust valves, 3 cylinder heads, 4 cylinder blocks, 5 second suction ports, 6 pistons, 7 spark plugs, 8 second intake ducts.
Embodiment
Below in conjunction with Fig. 1 the utility model is described in further detail.
The utility model improves on the basis of existing four-stroke gasoline engine and realizes, is to add second suction port 5 and second intake duct 8 on the existing four-stroke gasoline engine that comprises parts such as cylinder head 3, intake valve 1, exhaust valve 2, cylinder block 4, piston 6 and spark plug 7; Second suction port 5 is opened on the circumferential surface in cylinder block 4 cylinder holes and is between the top dead center and lower dead center of piston 6, and second intake duct 8 links to each other with second suction port 5.In intake stroke, inflammable mixture is still entered in the cylinder by intake valve 1, and the air of supercharging and the mixed gas of waste gas enter in the cylinder by second suction port 5 and along the casing wall fast rotational.During compression stroke, under the squeezing action of piston, inflammable mixture forms concentration by dense successively thinning stratification state, and spark plug 7 is lighted the higher inflammable mixture of concentration, by flame propagation, realizes stratified mixture combustion.
