SUITABLE FOR COLD START

At cold start tests the combustion analyzer runs and records signals already before the piston makes the first move. So the whole start process will be recorded for further investigation.

INPUT SIGNALS

Indicating & absolute pressure
Injection, timing signals
TDC sensors
Crank angle signals
CAN-in, CAN-out
XCP via LAN
FlexRay, LIN
Vibration, strain, temperature
Electrical power
VARIOUS INPUTS

Isolated charge amplifiers, bridge amplifiers with constant current supply feature, are used for high-pressure sensors and for the absolute pressure sensors of inlet and exhaust. Due to the changeable amplifier concept of the instrument, almost any signal like torque, current, acceleration, temperature, etc. can be measured.

Voltage inputs cover start of injection, end of injection and ignition, and any other additional signal captured in time or angle domain. The isolated voltage and current inputs can be used to calculate electrical power.

MOBILE OR TEST-BED

DEWETRON internal combustion analyzers are suitable for mobile application, like in-car usages and also for test-bed applications.

The systems support time and angle based measurement.

CRANKANGLE CPU

Included Crankangle CPU, is able to handle all kinds of crank marker disc signals which provides CDM- and TRIG- signal. In case more angle resolution is required, Crankangle CPU will do the interpolation up to 0, 1 deg.

Pickup sensors, for the native CDM signals, like 60-2, can be directly connected. The isolated input can handle voltages from 0, 5 V up to 60V. Crankangle CPU will do gap filling and interpolation.

Power Box

  • Voltage 12 to 16 VDC
  • Voltage 12 VDC or 24 VDC
POWERBOX-12
Power distribution for automotive applications
Optional backup battery connector for cold start
10 output connectors for several customer loads
High output current design
12 VDC or 24 VDC board supply
Indication of supply voltage level
The DEWE-POWERBOX-12 enables supply of multiple loads out of the vehicle battery up to a total power consumption of 600 W.

As supplying high power loads out of the typical 12 VDC board supply results in high currents (50 A for 600 W at 12 VDC) voltage drop through the supply lines must be considered and thus there is a high flexible 10 mm cable for the main supply line. A simple voltmeter indicates the voltage directly at the terminal board of the POWERBOX-12.
For cold start testing an optional backup battery can be attached to the POWERBOX-12 to buffer voltage drops of the vehicle battery.
