Single Cylinder Engine w. Variable Compression.
Single Cylinder Engine w. Variable Compression
In conjunction with the test stand, the engine makes up a complete engine test stand.
Major
technical modifications have been made to a standard water-cooled
single cylinder engine to allow demanding issues in engine technology to
be investigated by experiment. The key feature is that the cylinder has
been modified so that its height can be adjusted along with that of the
cylinder head. This allows the compression ratio to be adjusted over a
wide range.
The engine can be operated as an external ignition
petrol engine or an auto-ignition diesel engine. The mode of operation
can be changed by a few simple conversion steps.
In petrol engine
mode, it is also possible to change the ignition point and the
composition of the fuel/air mixture so that the influence of these
factors on the characteristic curves and values can be investigated
experimentally.
The engine is securely mounted on a base plate.
This unit is fitted in the test bed on the test stand and bolted into
place. It is connected to the brake unit using an elastic claw coupling.
The engine is fitted with sensors that measure temperatures and the oil
pressure. The sensors are connected to the test bed control cabinet.
The fuel supply hoses have self-sealing rapid action couplings. The
water cooling is provided by the and the laboratory network.
