GENERAL DESCRIPTION

The equipment is for testing an automotive engine with computer control.

The engine rests on four supports on one end of the test bed. The supports can be adjusted in three directions to accommodate different size engine. The dynamometer with speed and torque sensors rests on another end of the test bed. The engine is connected to the dynamometer by a double universal joint with a safety guard. Cooling of the engine and the dynamometer is by a cooling tower. A flexible stainless steel hose is provided for exhaust pipe connection.

Fuel tank with fuel flow and air flow measuring instruments are on a stand next to the engine. Data display, analysis, and control are by a touch screen computer.

Instruction manual is also included.

TYPICAL EXPERIMENTS
  • Torque vs engine speed at various throttle setting.
  • Engine brake horsepower and efficiency vs speed
  • Specific fuel consumption
  • Air/fuel ratio
  • Volumetric efficiency
