ELECTRICAL POWER CRANK ANGLE SIGNALS (CDM, TRG, TOOTH) ABSOLUTE PRESSURE (BRIDGE, VOLTAGE) CAN-IN, CAN-OUT STRAIN FLEXRAY, LIN HIGH PRESSURE (CHARGE) INJECTION, TIMING SIGNALS (VOLTAGE, CURRENT) COMBUSTION ANALYSIS DEWETRON internal combustion analyzers are suitable for mobile applications, such as real-time drive testing and also for test-bed applications. The systems support time and angle based measurement, and also provide various interfaces for test-bed automation and control. YOUR BENEFITS > In-vehicle and testbed application > Direct pressure and angle sensor connection > Engine calibration > Cold start testing > CAN input and output, various testbed links > Time and angle based measurement

SYNCHRONOUS INPUT SIGNALS Isolated charge amplifiers, bridge amplifiers with constant current supply features, are used for high-pressure sensors and for the absolute pressure sensors of inlet and exhaust. With the freedom to swap amplifiers as needed, almost any signal like torque, current, acceleration, temperature, etc. can be measured. Voltage inputs include the start of injection, end of injection and ignition, and any other additional signal captured in time or angle domains. The isolated voltage and current inputs can be used to calculate electrical power. Software provides easy to...

TESTBED INTERFACE Testbed interface, via RS232 or TCP/IP is provided to link the analyzer to a testbed for automated measurements. An open AK-protocol, or native interfaces for AVL PUMA Open, and DT2 is supported. In addition, calculated results can be also transferred via CAN-out. Results can be recorded from mapping tools for immediate feedback. Included Crankangle CPU, is able to handle of various crank marker disc signals which provides CDM- and TRIG-signals. If more angle resolution is required, the Crankangle CPU will do the interpolation up to 0.1 deg. Pickup sensors, for the native...
