This is commonly referred to as gauge pressure. Boost pressure is relative to absolute pressure - as one increases or decreases, so does the other. It is a one-to-one relationship with an offset of -100 kPa for boost pressure. Thus, a MAP sensor will always read 100 kPa more than a boost sensor measuring the same conditions.
Inlet manifold vacuum is measured using a pressure sensor located in, or connected to the intake manifold, in order to calculate the duration of fuel injection pulses. Originally, this system was called Jetronic, but the name D-Jetronic was later created as a retronym to distinguish it from subsequent Jetronic iterations.
Collectively, these are grouped into the 1000/2000 Series transmission family; transmissions within a family share the same basic dimensions, power input capabilities, and weight. Allison transmission families for the Bus Series include the 1000/2000 Series (B210, B220, B295), 3000 Series (B300 / B400), and 4000 Series (B500). [5]
Allison followed the WT (3000 and 4000 Series) line with the 1000 and 2000 Series starting in 1999. [3] The 1000 Series transmission incorporated many features from the WT line for light-duty trucks, including the electronic control system, and was initially available as an option with the 6.6L GM/Isuzu Duramax diesel engine and the 8.1L Vortec ...
The 1000 series (and similar 2000 and 2400 series) is a line of automatic transmissions for on-road trucks. All are 5 or 6-speed electronically controlled units and are manufactured by Allison Transmission in Indianapolis, Indiana as well as in Baltimore, Maryland and in Erskine, Minnesota .

Piping and instrumentation diagram of pump with storage tank. Symbols according to EN ISO 10628 and EN 62424. A more complex example of a P&ID. A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process.
