1.1 Properties
The ES4455.2 Load Carrier Board is a carrier board for load simulations, e.g.
injector loads, in a LABCAR HiL system.
To simulate injector loads, the following variants mounted with load modules
based on the ES4455.2 Load Carrier Board are available:
• ES4450.3 Load Carrier Board for 4 RB CRS Injectors
• ES4451.4 Load Carrier Board for 4 RB GDI Injectors
• ES4452.1 Load Carrier Board for 4 RB GDI Injectors, CVO
• ES4453.1 Load Carrier Board for 4 RB HDEV6 GDI Injectors, CVO
• ES4457.1 Load Carrier Board for 4 RB CRS Injectors, VCC and VCA
• ES4458.1 Load Carrier Board for 4 RB PFI Injectors, CVO
ES4450.3 and ES4451.4 are the successors to ES4450.2 and ES4451.3. The
ES4450.3 and ES4451.4 have the same functions as their respective predecessor
models.
The ES4452.1 Load Carrier Board for 4 RB GDI Injectors, CVO, ES4453.1 Load
Carrier Board for 4 RB HDEV6 GDI Injectors, CVO, the ES4457.1 Load Carrier
Board for 4 RB CRS Injectors, VCC and VCA and the ES4458.1 Load Carrier Board
for 4 RB PFI Injectors, CVO have an expanded scope of functions. They enable an
additional more precise simulation and modulation of the injection time through
integrated functions for the control algorithms of the ECU. These control algo-
rithms are CVO (Controlled Valve Operation) control for gasoline direct injection
in the case of ES4452.1, ES4453.1 and ES4458.1 or VCC (Valve Close Control)
control and VCA (Valve Close Adjustment) control for diesel direct injection in the
case of ES4457.1.
The expanded functions can be deactivated by the user in LABCAR OPERATOR.
After deactivating the function for CVO, the ES4452.1 can be operated analo-
gous to ES4451.4 and ES4451.3. Also, the ES4457.1 can be used in the same
way as ES4450.3 and ES4450.2 after deactivating the function for VCC and
VCA.
