Gasoline Engine Test Bench – For Advanced Training

Model No. DL DKD011

LEARNING EXPERIENCE
The system is designed for the study and the understanding of the four-stroke gasoline combustion engine. It is possible
to perform the necessary tests to obtain the engine characteristic data referred to the performance of the engine.
Experiments can be performed manually or automatically by students who have to just indicate the required variables and the number of points for the realization of the graph.

Training objectives:
Motor – characteristic of the curves:
-Torque – Rotational speed.
-Brake horsepower – Rotational speed.
-Temperature – Rotational speed.
-Air/fuel ratio – Rotational speed.
-Specific fuel consumption – Rotational speed.

MAIN CHARACTERISTICS
The test bench is supplied in two parts:
– a four-stroke gasoline engine
– a breaking system (a three-phase asynchronous motor that can work as motor and generator, controlled by an inverter)
– The engine test bench is supplied with a complete computer system, in order to carry out several practical experiments.
– All the characteristics of the curves can be monitored and recorded.
