A rotating cam to operate the contact points. Contact Point Ignition System Operation.
Robert Bosch GmbH dates back to 1886 and today is the worlds largest supplier of automotive components.
Ignition contact points made in argentina. The position of the contact breaker is set so that it opens and hence generates a spark at exactly the optimum moment to ignite the fuelair mixture. This point is generally just before the piston reaches the top of its compression stroke. The contact breaker is usually mounted on a plate that is able to rotate relative to the camshaft operating it.
The cam to operate the contact points. The cam is relieved test the coil and condenser with suitable equipment to ensure that the breaker arm is not touching the cam replaceany parts found faulty. Face whilst the contact points are clpsed.
The adjustable point is fixed to a bracket pivotted in the centre and 4. The condenser provides a place where current can flow until the contact points are fully open. Contact Point Ignition System Operation.
With the engine running the distributor shaft and distributor cam rotate. This action causes the distributor cam to open and close the contact points. With the contact points wired to the primary windings of the ignition coil the contact.
Ignition points are a set of electrical contacts that switch the coil on and off at the proper time. The points are opened and closed by the mechanical action of the distributor shaft lobes pushing on them. The points have a tough job switching up to eight amps of current many times per second at highway speed.
Ignition Contacts Sets Points for vehicle manufacturers beginning with G H This list of part numbers for contact sets was put together using the cross reference sections of various makes of parts catalogues and comparing them with the latest Lucas numbers available. Transistorized Assisted Contact TAC Ignition System Figure 45 shows the TAC system. Advantages a The low breaker-current ensures longer life.
B The smaller gap and lighter point assembly increase dwell time minimize contact bouncing and improve repeatability of. In selecting contact materials for a specific application the design engineer will have to find the proper balance in material selection that allows the greatest likelihood of success. Generally as the conductive metal silver or copper increases contact resistance decreases and electrical and thermal conductivity increase but contact erosion and contact sticking or welding become.
The original ignition in your old car is probably based on induction discharge also known as contact ignition or basic ignition. The opening and closing of contact breaker points within the distributor induces a current in the coil sufficient to create a spark the basics of induction discharge ignition are described in the MayJune 2016 issue. As they close current from the ignition switch flows through the contacts into the coils primary windings and then off to ground.
This current generates a. - Contact point alignment. CAUTION Ensure the feeler gauge is clean before inserting it between the points.
Oil and grease will reduce the service life of the points. To use a dwell meter for adjusting contact points connect the red lead of the dwell meter to the distributor side of the ignition coil wire going to the contact points. Connect the black lead to ground.
The contact point ignition system consists of. A battery or magneto to supply low voltage current for the spark. Mechanical contact points to control the point of ignition.
A rotating cam to operate the contact points. A condenser to reduce arcing across the contact point surfaces. Tech A says that contact breaker points are a mechanical switch that opens and closes once for every ignition spark that is created.
Tech B says that contact breaker points send high voltage directly from the points to the spark plugs. Volkswagens have traditionally been fitted with ignition components from Bosch or Beru both fine German companies. These are also the two recommended suppliers for replacement ignition parts for your Volkswagen.

Lucas Style Breaker Points 54419827 68-72 BSA Triumph 250 441 500 6CA LU53. ACCEL ignition contact points are equipped with extra-thick contact arms to prevent flexing on the top end. Their large radiused tungsten contacts provide crisp circuit breaking for peak coil output.
They also feature high-strength phenolic rubbing blocks for superior durability when used with heavier spring tensions. In vehicles there are different types of ignition systems used like contact breaker breaker less and capacitor discharge ignition. The contact-breaker ignition system is used to activate the spark.
This kind of ignition system is used in an earlier generation of vehicles. The breaker-less is also known as contactless ignition. 4 Types Of Ignition System.
1 Distributor-Based Breaker-Point Ignition Mechanical History. The oldest type of ignition system is the conventional breaker-point ignition system which sometimes is also called mechanical ignition systems. It has been used since the early days of the automobile industry especially through the 1970s.
Leaving the ignition switched on with engine not running and points closed for long periods of time may also burn out a coil. One of the side effects of low coil resistance and high current is possible over heating of the contact points. This high current can burn contact points or melt the plastic rubbing foot on the contact points.
Thereforemagneto ignition is very popularly used in racing cars. It is used for medium to high speeds. Space required is less as compared to the coil ignition system.
By providing suitable shunts on magneto the danger of burning of the spark plug is minimized. Very light in weight and compact in size. The Citroën Mehari fits into this category neatly and when FVFILIPPETTI grew tired of the unreliable points ignition system he decided to build a more modern replacement.
The system is based. Difference between the contact point and electronic ignition system. In the secondary circuit the distributor ignition coil and wiring are altered to handle the higher voltage that the electronic ignition system produces.
The high voltage about 47OOO volts has the advantage that the spark plugs with wider gaps can be used. That the points are closed pry the breaker arm open and insert a clean business card between the contact surfaces. Release the breaker arm so that the points grip the end of the card and then drag the card through its width wiping the contacts in the process.
The card has two properties which make it work. It is absorbent enough to remove oil and gently. Details about USA Made Ignition Contact Points For Studebaker Packard see compatibility chart.
