Engine sumpA baffle is a dividing partition in a sump, reservoir or exhaust box. The partition divides the area inside, but does not seperate it. For example, in the sump of an engine, the baffle plates stop the oil surging around, thus reducing the possibility of oil starvation if the vehicle is suddenly braked or is operated on a slope.

In the reservoir of a hydraulic system, the sump has a similar function, to prevent oil surging around. There is also a secondary function of assisting in cooling.

In an exhaust silencer box, there are baffles which assist in taking some of the engery out of the exhaust gasses and convert this engergy to heat. This makes the exhaust quieter.

The CP Fitters' Section operates under the auspices of the Baldoyle Training Centre.

The CP Fitters' Section is located in a satellite industrial unit in the Baldoyle Industrial Estate, about 300 metres away from the Baldoyle Training Centre.

Please note, if you ring CP Fitters, we cannot put you through to the FAS training centre. CP Fitters have their premises in a different part of the Baldoyle Industrial Estate, and we are on a separate telephone network.

Ball jointThis is a spring loaded ball and socket joint used mostly in the steering systems of plant vehicles. The joint allows a range of movement between the various rods and linkages that make up the steering system.

If the ball joints are fitted to the track control rod, they may be called 'track control rod ends'. These have the same basic construction as the ball joint, they are just named differently because of where they are used.

Read more here on ball joints and check out the overall layout of the steering system here.

A bar is a measure of pressure.

1 bar = 100 kPa, or

1 bar = 100,000 Pascals.

The conversion factor to the Imperial way of measuring pressure is 14.5

In other words to convert bar to psi (pounds per square inch), multiply by 14.5.

Example: Convert 2 bar to psi.
Answer = 2x14.5 =29 psi.

Although bar and atmospheres (atm) are very similar ways to measure pressure, they are not the same:

1 bar = 100 kN/m2 = 14.5 psi

1 atm = 101.3 kN/m2 = 14.7 psi

In the SI, there are 7 base units of measurement. The ones we come across in the phase 2 course are:

Other units of measurement such as those for torque, speed, power etc. are all based on SI units of measurement, so they are said to be 'base derived' units of measurement.

A base limiting resistor is inserted into an electronic circuit in order to protect the delicate base/emitter circuit of a transistor. Unlike the more robust collector/emitter, the base/emitter circuit cannot pass large currents, it can only pass small currents. The transistor works by taking the small base/emitter current and amplifying it-allowing a much larger collector emitter current to flow.

In order to limit the current flowing into the base of a transistor, we fit a resistor in series into the circuit. This has the effect of limiting the current flowing into the base/emitter circuit of the transistor.

A base limiting transistor.

Note:-
Transistors need not always have a base limiting resistor fitted. Sometimes the incoming current (or signal) is so small that there is no danger to the transistor. In these cases, the function of the transistor is usually to amplify the signal so that it can be used by other parts of the electronic system.
