Peak And Hold 2A/0,5A - 4 Bosch 160Lb/H Injectors; Peak And Hold 4A/1A - 6/8 Bosch 160Lb/H Injectors - (Two Injectors Per Channel) - FuelTech Peak and Hold Manual De Instalación Y Operación

Peak and Hold
5.2 Peak and Hold 4A/1A – 4
Siemens, MSD injectors
Wiring example of 4 fuel injectors with
impedance between 1 and 3 ohms.
5.3 Peak and Hold 4A/1A – 6/8
Bosch 160lb/h injectors - (two
injectors per channel)
EN
Control of 8 Bosch 160lb/h fuel injectors
onto a Peak and Hold 4A/1A. The same
wiring example can be used for fuel
injectors with impedance above 3 ohms
(including high impedance fuel injectors).
In the example above, 4 fuel injectors are
driven through Bank A and the other 4 are
driven through Bank B. If necessary, it is
possible to join all 4 Peak and Hold inputs
to drive all the fuel injectors through one
injection bank.
In 6-cylinder engines, it is possible to leave
one Peak and Hold channel disconnected or
use that channel to control supplementary
fuel injectors through Bank B.
5.4 Peak and Hold 8A/2A – 4
Precision 550 lb/h, 4 Moran or 4
Billet Atomizer
These injectors are exceptions to the rule,
as they have between 1 and 3 Ohms, but,
must be connected using an 8A/2A Peak
and Hold driver.
