Automotive Engine Test Bed , Water absorber
OSC77FD505MTHC
Features
-The equipment is for testing an automotive engine with computer control-The engine is connected to a hydraulic dynamometer by double universal joints, and is supported on four legs which can be adjusted in three directions to accommodate several size engine
-Cooling the engine and the dynamometer is by a cooling tower outside the engine room
-A fuel tank with a fuel flow ad an air flow measuring instruments are on a stand next to the engine
-Control of dynamometer load and engine throttle is by push buttons
-A human machine interface (HMI) unit, an input / output module, control motors and software are provided for data display, analysis, and touch screen control
.
Typical tests
-Torque vs engine speed at various throttle setting-Engine brake horsepower and efficiency vs speed
-Specific fule confumption
-Air / fuel ratio
-Volumetric efficiency
