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 during engine start due to the high temporary battery current usage.

Some automobile accessories are connected directly to the engine through gears or belts.These usually require large amounts of power. The air conditioning compressor has been a familiar example, though new all-electric refrigerant compressors are starting to be used in production vehicles.
Electricity is required to heat the ignition source, with systems designed to be compatible with 6-volt, 12-volt, and 24-volt automotive and aircraft electrical systems. Most gasoline heaters produce between 5,000 and 50,000 BTU per hour. A built-in safety switch prevents fuel from flowing unless the fan is working.
HVAC ventilation exhaust for a 12-story building An axial belt-drive exhaust fan serving an underground car park. This exhaust fan's operation is interlocked with the concentration of contaminants emitted by internal combustion engines. Mechanical, or forced, ventilation is provided by an air handler (AHU) and used to control indoor air quality.
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;
Engine fan with viscous drive. A fan clutch is a thermostatic engine cooling fan that can freewheel at low temperatures when cooling is not needed, allowing the engine to warm up faster, relieving unnecessary load on the engine. As temperatures increase, the clutch engages so that the fan is driven by engine power and moves air to cool the engine.
