A real-time operating system (RTOS)[Generally pronounced as: Or-tos] is a multitasking operating system intended for real-time applications. Such applications include embedded systems (programmable thermostats, household appliance controllers, mobile telephones), industrial robots, spacecraft, industrial control (see SCADA), and scientific research equipment. An RTOS facilitates the creation of a real-time system, but does not guarantee the final result will be real-time; this requires correct development of the software. An RTOS does not necessarily have high throughput; rather, an RTOS provides facilities which, if used properly, guarantee deadlines can be met generally (soft real-time) or deterministically (hard real-time). An RTOS will typically use specialized scheduling algorithms in order to provide the real-time developer with the tools necessary to produce deterministic behavior in the final system. An RTOS is valued more for how quickly and/or predictably it can respond to a particular event than for the given amount of work it can perform over time. Key factors in an RTOS are therefore a minimal interrupt latency and a minimal thread switching latency.

Pentosin....CHF-11S Pretty expensive but the only one recommended. OReilly Auto has it or can transfer it in for you. Bj

The 2005 BMW Z4 has an inline 6 engine.

The 2006 BMW Z4's turning circle is 32.2 ft..

The 2013 BMW Z4 has 16 valves.

It's such a shame because it's a fantastic range. You cannot get it in the UK at moment.

It depends on what model year you are talking about. Most recent BMW's (post 2006) have an electronic oil check that you access by pressing a button on the dash. Therefore, there is no actual "dipstick" in the engine bay.

They cost about £330,000 and you can get them in roadster version or coupe. They go 208mph and have about 600bhp. Mercedes have recently stopped poduction of these cars because of poor sales, so if you happen to be signing for a premiership football club in the next few months you could be dissapointed.

As far as I know, the older BMW uses brake sensor inline with the brakpads. Once the pads are low enough, the sensor get worn down, which use to conduct electricity no longer do so. As a result, the sensor lights are tripped. To reset the lights, you need to replace the brake sensors.

The oil on a BMW Z4 is changed by putting a oil drain pan under the engine, placing the vehicle on jack stands, and removing the oil drain plug. The oil is then allowed to drain, the plug re-installed, and the engine filled with oil.

The 2005 BMW Z4 has a drag coefficient of .35 Cd.
