Abstract

A rotor arm distributor (10) and its variation, is to add a layer of tin or brass or alloy of tin and brass to the front end of the conducting strip (12) of the conventional rotor arm to improve, in order to increase the 'contact' area between it and the fixed metal contact on the distributor cover, thus make the electric current that circulates to the spark plug produce the stronger spark, make the fuel burn better, increase the output power of the engine, therefore can save about 5% to 10% of the fuel, and reduce the pollution to the air.

Description

Improvement in rotating spark distributors for spark-fired engine

The invention relates to the improvement of plug ignition formula internal-combustion engine ignition rotor spiral arm,, save the fuel that motor consumes simultaneously in order to increase engine horsepower.

The function of distributing disk rotor is that electric current is assigned on each spark plug of internal-combustion engine, makes the fuel vapour in its energy ignition engine cylinder, thereby drives motor.Rotor normally is made of the core of a plastic colloid and conducting plate fixed thereon (normally latten).Generally speaking, conducting plate thickness is less than 1.7 millimeters, but local modification was constantly done in its design for many years.

Rotor is rotation in fixed a plurality of contacts (each contact is represented a cylinder of motor usually) scope, make when engine running and during the rotation of rotor spiral arm, the high-tension current in input rotor spiral arm axle center can take turns to pass through between conducting plate end and each fixed contact.

Because plug ignition formula internal-combustion engine is widely used in automotive, therefore extensively studied for the improvement of engine output or fuel consumption aspect.The present invention's and part-distributing disk rotor of being easy to change cheap-carried out simple but be not to be easy to revise to one of plug ignition formula internal-combustion engine, thus the performance of this class motor improved.

The invention provides a kind of rotor spiral arm conducting plate that is extended with big terminal edge area.This terminal edge has the alloy-layer of a tin layer or tin and brass.According to the present invention, when rotating in the scope between the fixing metal contact of rotor spiral arm in distributor head, because of the streamed area of can powering on the conducting plate is bigger, so can provide one to flow in the spark plug than heavy current.This metal layer thickness of additionally setting up can be 1.5 millimeter.

According to the rotor spiral arm that has improved of the present invention, can make spark plug produce stronger spark plug and produce stronger spark, therefore can cause better burning to reach the more engine running of cleaning, thereby engine horsepower is increased, save 5% to 10% fuel consumption and reduce the atmospheric pollution that engine exhaust causes.

Therefore, the objective of the invention is to improve the structure of automobile-used rotor spiral arm, be equipped with the larger area conducting plate at the end of its rotor spiral arm, so that on spark plug, produce stronger spark, thereby cause preferable firing effect, promote combustion efficiency, reduce exhausted air quantity.

Below will cooperate the graphic the present invention that further illustrates, wherein:

Fig. 1 demonstrates common rotor spiral arm;

Fig. 2 demonstrates rotor spiral arm of the present invention.

Rotor spiral arm 10 shown in Figure 1 comprises an electrical insulation core support 11(of portion and is for example made by ebonite), establish a conducting plate 12(who radially is provided with on it and for example make by brass), an end 13 had.Be led to the radially inner side end of conducting plate 12 in order to the high-tension electricity that starts spark plug, the conducting plate of flowing through, and, form sparks from terminal 13 to pass on the fixed contact (not shown), thereby take turns starting each spark plug during around 14 rotations of its shaft axis at rotor spiral arm 10.The thickness that conducting plate 12 is located endways generally is 1.5 millimeters.

Rotor spiral arm 10 shown in Fig. 2 and difference shown in Figure 1 only are to add an extension part 15 on its end 13.Extension part 15 is to be made by the alloy of tin or a kind of tin and brass, and its thickness end 13 with conducting plate 12 at least is suitable, and extends 1 to 2 millimeter diametrically, and length for example is 2 millimeters, roughly cooperates with the width of end 13 on the ring Zhou Fangxiang that spiral arm moves.In above-mentioned alloy, tin is about 50%: 50% with the ratio of brass.

In another kind changed, extension part 15 was to be made by brass, its along the axial thickness of core support portion 11 between 1.75 to 3.0 millimeters or the bigger value.
