Breaker arm with contact points at the left. The pivot is on the right and the cam follower is in the middle of the breaker arm. A contact breaker (or "points") is a type of electrical switch, found in the ignition systems of spark-ignition internal combustion engines. The switch is automatically operated by a cam driven by the engine.
The block wears over time, reducing how much the points open (the "point gap") and causing a corresponding change in both the ignition timing and the fraction of time during which the points are closed. Tune-ups for older vehicles usually involve replacing the points and condenser and setting the gap to factory specifications. A third problem ...
Points bounce is a feature of a points-triggered system. In the standard system with points, distributor, ignition coil, ignition (Kettering system) points bounce prevents the coil from saturating fully as RPM increases resulting in a weak spark, thus limiting high speed potential. In a CD ignition, at least those early attempts, the points ...
As batteries became more common in cars (due to the increased usage of electric starter motors), magneto systems were replaced by systems using an induction coil.The 1886 Benz Patent-Motorwagen and the 1908 Ford Model T used a trembler coil ignition system, whereby the trembler interrupted the current through the coil and caused a rapid series of sparks during each firing.
The starting point in carrying out an estimate both for cooling and heating depends on the exterior climate and interior specified conditions. However, before taking up the heat load calculation, it is necessary to find fresh air requirements for each area in detail, as pressurization is an important consideration.
This feature resulted in the condenser/capacitor bushing. The condenser bushing is made by inserting very fine layers of metallic foil into the paper during the winding process. The inserted conductive foils produce a capacitive effect which dissipates the electrical energy more evenly throughout the insulated paper and reduces the electric ...
Steam enters the IC condenser and condenses until it is filled with water. When the IC system is activated, a valve at the bottom of the IC condenser is opened which connects to a lower area on the reactor. The water falls to the reactor via gravity, allowing the condenser to fill with steam, which then condenses.
The condenser's increased contrast emphasises any negative defects, such as dirt and scratches, and image grain. A point source enlarger is a variation of the condenser enlarger designed to cut light diffusion above the negative. Contrast is enhanced and grain in the resultant print is sharper than with a conventional enlarger, and the ...
