Frequently Asked Questions; BOSCH Spark Plug Function - General.pdf

November 22, 2009 · Filed Under Auto Parts & 3rd Parties · Comment  · Tags: ,

Taken from Why do we need to change spark plugs?: During operation, the spark plug is subjected to both wear and to fouling and should be replaced at regular intervals. In the course of its service life, the spark plug undergoes changes that increase the required ignition voltage. When the required voltage reaches a level that can no longer be compensated for by the voltage reserve, the result is misfiring. These changes can be caused by:
Electrode wear
Engine wear
Abnormal operating conditions (pre-ignition, detonation, high oil consumption)
Independent tests have shown that installing premium spark plugs such as Bosch’s Platinum+4 improves fuel mileage by as much as 4.8% over original equipment plugs. Platinum+4 uses racetested technology including multiple electrode paths and large amounts of platinum to generate strong, consistent sparks.

Automating Manufacturing Systems with PLCs.pdf

Taken from PROGRAMMABLE LOGIC CONTROLLERS’s Introduction: Control engineering has evolved over time. In the past humans were the main method for controlling a system. More recently electricity has been used for control and early electrical control was based on relays. These relays allow power to be switched on and off without a mechanical switch. It is common to use relays to make simple logical control decisions. The development of low cost computer has brought the most recent revolution, the Programmable Logic Controller (PLC). The advent of the PLC began in the 1970s, and has become the most common choice for manufacturing controls.
PLCs have been gaining popularity on the factory floor and will probably remain predominant for some time to come. Most of this is because of the advantages they offer: Cost effective for controlling complex systems.
Flexible and can be reapplied to control other systems quickly and easily.
Computational abilities allow more sophisticated control.
Trouble shooting aids make programming easier and reduce downtime.
Reliable components make these likely to operate for years before failure.
