Abstract
The utility model relates to an automotive engine ignition system, wherein two additional spark plugs which are respectively arranged at a cylinder port with the surface facing downwards slightly pass through the part of a cylinder wall perpendicular to the axial direction of the spark plugs and being in 180 degrees; the parts of the internal end face of a piston corresponding to the additional spark plugs are respectively provided with a concave pit; in addition, each additional spark plug is connected with an ignition coil and is controlled by a primary electron ignition controller. Due to adding the two additional spark plugs, three spark plugs can ignite simultaneously and the flame is transmitted alternately to ignite the mixed gas inside a quenching zone so as to realize fully burning of the mixed gas; thereby, the utility model not only eliminates environmental pollution caused by emission of unburned gas, but also increases power of engine and saves fuel.
Description
The utility model relates to car engine ignition system.
At present, existing automobile igniter is the control ignition moment and ignition performance effectively, for example: the computer ignition system of distributor and the computer ignition system system of no distributor are arranged, but all there is a shortcoming in they, a spark plug that has only the cylinder head center exactly, during work after spark plug produces the spark ignition mixed gas, flame to around spread, when flame spread arrives near cylinder wall and piston upper surface, because these regional temperatures are low, add flame propagation and need the time to these places, just extinguished before causing flame to arrive these zones, therefore can not burn apart from wall and the thick interior mixed gas in zone of piston face 0.5mm, so claim this zone to be the cold district of putting out.Be positioned at the cold mixed gas that puts out the district and also have little time oxidation (burning), just released cylinder by up piston, be discharged into befouling environment in the atmosphere in exhaust stroke.
The purpose of this utility model just provides a kind of cold clean-burning igniting of mixed gas system of putting out the district that can make in the cylinder, to reduce or eliminate discharge of harmful gases.
Technological scheme of the present utility model is: the utility model comprises igniting system, comprise cylinder, piston, electronic igniting controllor, spark coil, spark plug, spark coil is connected with spark plug with electronic igniting controllor respectively, spark plug is positioned at the center hole of cylinder head, also have two additional spark plugs to place the cylinder port surface respectively slightly downwards, it is axially vertical with it and be 180 ° position to pass cylinder wall, respectively there is a pit at position at the corresponding described additional spark plug of piston interior edge face, and each additional spark plug all connects a spark coil and controlled by electronic igniting controllor.
Described additional spark plug is positioned at downward 1 millimeter place, cylinder port surface.
The utility model has the advantages that: owing to increased by two additional spark plugs, three spark plugs are lighted a fire simultaneously, flame-shaped becomes delivery ceremony to propagate, the cold mixed gas that puts out in the district is lighted it is fully burnt, both eliminated the pollution of the discharging of unburned gas to environment, increase the power of motor again, saved fuel.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is that prior art igniting system forms the cold schematic representation that puts out the district;
Fig. 2 is the schematic representation of structure of the present utility model and flame propagation;
Fig. 3 is the view of fire plug end of the present utility model.
Referring to Fig. 1, existing automotive ignition system has only a spark plug 1 at cylinder head center, during work after spark plug 1 produces the spark ignition mixed gas, flame 4 to around spread, when flame 4 is diffused into upper surface near the inwall of cylinder 2 and piston 3, because these regional temperatures are low, adding flame 4 propagates into these places and needs the time, just extinguished before causing flame 4 to arrive these zones, therefore can not burn apart from wall and the thick interior mixed gas in zone of plug surfaces 0.5mm, so claim this zone to be the cold district 5 of putting out.
Referring to Fig. 2, the utility model comprises cylinder 2, piston 3, electronic igniting controllor 6, spark coil 7, spark plug 1, spark coil 7 is connected with spark plug 1 with electronic igniting controllor 6 respectively, spark plug 1 is positioned at the center hole of cylinder head 9, also have two additional spark plugs 11 to place cylinder port surface 10 respectively slightly downwards, the wall that passes cylinder 2 is axially vertical with it and be 180 ° position, respectively there is a pit 13 at position at the corresponding described additional spark plug 11 of piston 3 interior edge faces, each additional spark plug 11 all connects a spark coil 7, and by electronic igniting controllor 6 controls.
Described additional spark plug 11 is positioned at 10 downward 1 millimeter place, cylinder port surface.
Claims (2)
1, a kind of car engine ignition is, comprise cylinder, piston, electronic igniting controllor, spark coil, spark plug, spark coil is connected with spark plug with electronic igniting controllor respectively, spark plug is positioned at the center hole of cylinder head, it is characterized in that: also have two additional spark plugs place respectively the cylinder port surface slightly downwards, to pass cylinder wall axial vertical and be 180 ° position with it, respectively there is a pit at position at the corresponding described additional spark plug of piston interior edge face, and each additional spark plug all connects a spark coil and controlled by electronic igniting controllor.
2, car engine ignition according to claim 1 is, it is characterized in that: described additional spark plug is positioned at downward 1 millimeter place, cylinder port surface.
