Instrumentation & Controls

Instrumentation

Inlet manifold temperature – One Individual cylinder exhaust gas temperatures – Three Cooling water inlet temperature Cooling water outlet temperature Cooling water flow Oil pressure Oil temperature Ambient temperature Measured torque Engine speed Gasoline fuel flow rate (Diesel on Diesel Engine) Alternative fuel flow rate (Optional on LPG or NG) Inlet manifold pressure for estimating the air flow Real time cylinder pressure display

Combustion Pressure Sensor which allows you generate P/V Diagrams and calculate indicated horsepower

Note: Power is calculated from Measured Torque & Engine Speed

Controls

• Fuel selected – Manual control from control box
• Vernier Control for Precise Movement
• Throttle – Cable controlled
• Choke – Cable controlled
• Exhaust back pressure valve – Manually controlled
• Brake load – On/Off controls at the control box. Braking load then controlled from computer

Note: Two methods of Brake Load control are available via the computer, a manual control which applies a percentage of full load, and a closed loop control which varies the load in order to maintain a pre-set speed. In closed loop control the operator has full access to the PID control parameters.
