  • Page 22: Rpm Module (Standard)

    2.7.1 RPM Module (Standard) The RPM module is used to record the RPM and oil temperature (Plug-in card CAN DRZ). The following RPM sensors/sources can be used: Trigger Tongs The RPM signal is picked up at the ignition cable (spark plug or distributor ignition coil) with the trigger tongs.
  • Page 23 TDC Sensor The TDC sensor is always manufacturer-specific, i.e. depending on the vehicle manufacturer the corresponding diagnostic plug is used for the RPM signal pick up. The TDC sensor offers an extremely accurate RPM measurement. Once f is reached, an RPM of 12000 rot/min is displayed.

  • Page 24: Environmental Module (Standard)

    At the beginning of a test a pre-determined RPM value must be approached ('Test gear' / Gear transmission close to 1:1) while in a specific gear. This RPM value will be stored. During the performance test the software will convert the roller’s current RPM into engine RPM. (Please note: The calculated RPM will only correspond if the vehicle is driven in the 'test gear'.) Automatic transmission vehicles without converter lockup cannot use the driving trial method, be- cause the engine RPM deviates due to converter slip.

  • Page 25: Pressure/Temperature Module (Optional)

    Air Pressure The air pressure is recorded using the interface box and is used for projection of the engine performance based on DIN 70020, EWG 80/1269, ISO 1585, SAE J1349 or JIS D1001. Humidity The humidity is recorded using the interface box and is used for projection of the engine performance based on DIN 70020, EWG 80/1269, ISO 1585, SAE J1349 or JIS D1001.

Measurement data from –10 V to +10 V or from –20 mA to +20 mA can be recorded. Analog Output Card (Optional) The analog output card (Plug-in card LON OUTA) is used for further processing of measured values as analog signals for an external device (e.g.

  • Page 33: Installation

    Installation Requirements for the Place of Installation The room in which the dyno is to be operated must satisfy all official regulations for the operation of equipment in the workplace. An adequate fresh-air supply and an exhaust shaft should also be available. Safety Measures The following technical safety precautions must be observed by the customer at all times.
  • Page 34 - Room size - Energy storage volume of the walls MAHA Experiences Cooling air is of special importance as modern engine management systems are equipped with control systems which reduce the engine power when intake temperatures are too high. The full engine power is however to be measured on the dyno.

  • Page 35: Exhaust Suction System

    3.2.2 Exhaust Suction System The exhaust quantity depends upon the test vehicle.The factors which are most influential are the engine cubic capacity and RPM as well as the combustion process (spark or compression ignition). As a safety precaution it is recommended that a CO warning device be installed in the test room.
