Abstract
The utility model relates to an ignition device for a multi-cylinder internal-combustion engine. A low-voltage DC power supply is connected with a primary coil of each boosting transformer through an electricity distributing basin, and the primary coil of each boosting transformer is connected with a sparking plug of a cylinder. The power supply is connected with a storage capacitor in parallel, and the primary coil of the transformer is connected with a protection capacitor in parallel. A movable contactor of the electricity distributing basin can obtain high voltage in a secondary coil of the transformer when the movable contactor rotates following the internal-combustion engine, and the high voltage is used for ignition. The utility model has the advantages of long service life, high combustion efficiency, etc.
Description
The utility model relates to a kind of ignition device for internal combustion.Especially a kind of ignition mechanism that is used for multi-cylinder engine.
Traditional multi-cylinder engine ignition mechanism is low-voltage dc power supply to be become be assigned to each cylinder spark plug by electric separation basin again behind the high-voltage pulse and light a fire.Wherein the movable contact of electric separation basin is rotated synchronously by internal-combustion engine drives, to light a fire to respective cylinder synchronously.It has many shortcomings, because electric separation basin divides electricity at high pressure, often produces spark, and the deterioration contact influences the life-span easily; Also weaken simultaneously the spark intensity of cylinder spark plug, influenced combustion efficiency.
The purpose of this utility model is the shortcoming that overcomes prior art, and the ignition device for internal combustion that a kind of life-span is long, oil inflame efficient is high is provided.
Scheme of the present utility model is, electric separation basin is connected on the low-voltage dc power supply, and the unexpected intermittent current of electric current obtains high-voltage pulse when utilizing electric separation basin to divide electricity when boosting transformer, is access to the cylinder spark plug.
Provide drawings and Examples below.
Accompanying drawing is the connection diagram of each components and parts of the utility model.
With reference to accompanying drawing, the utility model is by power supply (1), storage capacitor (2), electric separation basin (3), count the boosting transformer (4) of equal number and protect electric capacity (5), (6) to form with cylinder.One utmost point of power supply (1) is access to the movable contact of electric separation basin (3), and the primary air one end parallel connection of each boosting transformer (4) is access to another utmost point of power supply (1), and the other end of the primary air of each boosting transformer (4) is access to each fixed contact of electric separation basin (3) respectively.One end ground connection of the secondary winding of each boosting transformer (4), the other end are access to the igniter plug (7) of each cylinder respectively.
In addition, power supply (1) is parallel with storage capacitor (2), and the parallel connection of primary windings of each boosting transformer (4) has protection electric capacity (5), (6).
The movable contact of electric separation basin of the present utility model (3) and internal-combustion engine interlock.During work,, power cycle ground is powered successively to each boosting transformer (4) primary air along with the rotation of movable contact.In the moment that contacts and interrupt a certain transformer frequency response, can obtain high voltage at the secondary winding of this transformer, be used for plug ignition.
Because the voltage of electric separation basin is lower, avoided in the electric separation basin discharge, so long service life has guaranteed also that in addition each spark plug obtains stronger electrion with igniting, improves combustion efficiency.
What accompanying drawing provided is the ignition mechanism of four-cylinder internal combustion engine, according to the said structure principle, can design the multi-cylinder engine ignition mechanism of other cylinder numbers, does not enumerate one by one as space is limited.
Claims (2)
1. a multi-cylinder engine ignition mechanism is characterized in that by power supply (1), storage capacitor (2), electric separation basin (3), counts the boosting transformer (4) of equal number and protect electric capacity (5), (6) to form with cylinder; One utmost point of power supply (1) is access to the movable contact of electric separation basin (3), and the primary air one end parallel connection of the power transformation device (4) that respectively boosts is access to another utmost point of power supply (1), and the other end of the primary air of each transformer (4) is access to each fixed contact of electric separation basin (3) respectively; One end ground connection of the secondary winding of each boosting transformer (4), the other end are access to the igniter plug (7) of each cylinder respectively.
