Thermal Engineering Lab Equipment

Four Stroke Four Cylinder Petrol Engine Test Bench



The “LabTek” experimental engine test stand. The engine used here is a four-cylinder petrol engine with a controlled catalytic converter. It has its own closed cooling water circuit.

A solid welded frame on rollers carries the entire setup. Hazardous areas such as hot surfaces and rotating parts are covered with perforated plates. The connection to the brake is made via a rotationally elastic coupling with a jointed shaft. The engine is attached to the load unit by fasteners.

For safety reasons, the engine has been modified in a way that it only starts when it is connected to the load unit both mechanically and electrically.

The engine software runs on a personal computer, requiring only a single USB interface between the electronic console and the PC.
