DESCRIPTION

Technical Description

In conjunction with the CT 110 test stand, which includes a drive and brake unit, the four-stroke diesel engine is highly suitable for use in teaching the fundamentals of engine functioning and measurement.

The engine used here is an water-cooled single-cylinder four-stroke diesel engine with indirect injection. The engine is started by an electric motor mounted in the CT 110 unit. The water circulation (for cooling) contains a circulating pump, flow meter and temperature sensors. The brake unit is connected by way of a elastic claw coupling.

The engine is prepared for measurement of the cylinder pressure for indication, and additionally includes a sensor to measure the exhaust gas temperature. The sensors as well as the power supply of the circulating pump are connected to the CT 110 test stand.

The full load and partial load characteristic curves of the engine are plotted in experiments.

Learning Objectives / Experiments

In conjunction with CT 110 test stand
- familiarisation with a water-cooled four-stroke diesel engine
- plotting of torque and power curves
- determination of specific fuel consumption
- determination of volumetric efficiency and lambda (fuel-air ratio) 
- determination of engine friction loss
- determination of amount of heat emitted by the engine
