Single Cylinder Four Stroke Diesel Engine Test Bench

The experimental 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 air-cooled single-cylinder four-stroke diesel engine with direct injection.
The diesel engine is started and slowed down by an electric motor mounted in the unit.
A flywheel fan affects the air-cooling.
The brake unit is connected by way of a elastic claw coupling.
The engine is prepared for measurement of the cylinder pressure for indication.
It includes a sensor to measure the exhaust gas temperature and a connection to measure the intake pressure.
Both sensors, ignition cut-off and fuel supply are connected to the test stand.

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