Some benefits of an automotive TSB are that by widely circulating among dealership service departments and mechanics an engineering-level description and solution for a problem common to type, year, make or model of car, a well-managed TSB process can save technicians troubleshooting time; provide organized, itemized repair procedures; and ...
A group of tell-tales showing lights for "brake fluid", "stop lamp" and "check engine" Graphical tell-talesA tell-tale, sometimes called an idiot light [1] or warning light, is an indicator of malfunction or operation of a system, indicated by a binary (on/off) illuminated light, symbol or text legend.
The system drew in more outside air than contemporary systems; thus, reducing the staleness associated with automotive air conditioning at the time. Instead of plastic tubes mounted on the rear window package shelf as on GM cars, small ducts directed cool air toward the ceiling of the car where it filtered down around the passengers instead of ...
It is cheap, nontoxic, and has a high heat capacity. It however has only a 100 Kelvin liquid range, and it expands upon freezing. To address these problems, alternative coolants with improved properties were developed. Freezing and boiling points are colligative properties of a solution, which depend on the concentration of dissolved substances ...
An air conditioner designed for an occupied space will typically achieve a 30% to 60% relative humidity in the occupied space. [51] Most modern air-conditioning systems feature a dehumidification cycle during which the compressor runs. At the same time, the fan is slowed to reduce the evaporator temperature and condense more water.
The outlet is connected directly to the electrical system of the car. The actual voltage, matching the car battery's voltage, will be approximately 12.5 volts when dormant (less in cold conditions), approximately 14.5 volts when the engine and the alternator/generator are operating (more when cold), and may briefly drop as low as 5–6 volts ...
A typical automotive cooling system comprises: a series of galleries cast into the engine block and cylinder head, surrounding the combustion chambers with circulating liquid to carry away heat; a radiator, consisting of many small tubes equipped with a honeycomb of fins to dissipate heat rapidly, that receives and cools hot liquid from the engine;
The Ford EEC (Electronic Engine Control) system, which utilized the Toshiba TLCS-12 microprocessor, went into mass production in 1975. [ 7 ] The first Bosch engine management system was the Motronic 1.0 , which was introduced in the 1979 BMW 7 Series (E23) [ 8 ] This system was based on the existing Bosch Jetronic fuel injection system, to ...
