SINGLE CYLINDER RESE ARCH ENGINE
AVL 5 70
SINGLE CYLINDER COMP ACT TEST BED
NEW GENERATION (3G)

The AVL Single Cylinder Engine Test Bed is a cost -efficient compact system for professionally
operating single cylinder engines. It is the ideal solution for new single cylinder installations. The
complete system is assembled wired and tested at AVL before delivery.

The single cylinder engine test bed has been developed as a flexible modular system. It can be
installed as either a standar d low cost solution or as an upgraded customized version, able to accept
a wide range of single cylinder engine sizes and also suitable for small multi -cylinder engines and
other applications requiring a drive unit, e.g. friction tests.

Its flexible but compact design allows shortest installation
times even in the smallest test cell, e.g. a container. Only
external supply for cooling water and electrical signals have to
be provided locally to operate the test bed, all equipped with
quick connectors. As t he test bed base frame is mount ed at
four shock -absorbers the single c ylinder engine test b ed can
be installed in common test cells as well as in containers, garages or rooms without any special demands on the ground
floor regarding vibrations damping.
The test bed comprises an active powerful AC dyno including
the complete converter and electronics, torque flange and an
engine mounting plate – everything mounted on a common
base frame with minimum space requirements .
