MT 505 AUTOMOTIVE ENGINE TEST BED
GENERAL DESCRIPTION

The equipment is intended for testing automotive engine.

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 to minimize test room temperature rise. A flexible stainless steel hose is provided for exhaust pipe connection. Engine throttle and dynamometer load control are by knobs.

Instruments are provided for measurement of dynamometer torque and speed, fuel flow rate, air flow rate, and temperatures.

A fuel tank with fuel flow and air flow measuring instruments are on a stand next to the engine.

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