Single Cylinder Four Stroke Petrol Engine Test Bench

Single Cylinder Four Stroke Petrol Engine Test Bench

The engine used here is an air-cooled single-cylinder four-stroke petrol engine with external carburation.
The engine is started and slowed down by an electric motor mounted in the unit.
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.
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.
The full load and partial load characteristic curves of the engine are plotted in experiments.
