SMALL ENGINE TEST SET

A versatile hydraulic engine test bed with comprehensive
instrumentation. The equipment requires minimum
services, installation and outlay. When used with one of
TecQuipment?s optional single-cylinder engines, it safely
and effectively enables study and demonstrations of the
most important features of the engine. In addition,
optional ancillaries are available to extend the range of
study, demonstrations and investigations even further.
The equipment is fully compatible with TecQuipment?s
Versatile Data AcquisitionSystem (VDAS? available
separately). Using VDAS? enables accurate real-time data
capture, monitoring and display, calculation and charting of
all relevant parameters on a computer (PC available
separately) making tests quick and reliable.
The main components of the test set are:
– a heavy fabricated portable bed
– a bench-mounted instrumentation frame
The bed sits on a trolley for portability. It includes a robust,
precision-machined, trunnion-mounted hydraulic
dynamometer. A significant advantage of using a hydraulic
dynamometer is that no large electrical supplies are
required as the engine power is dissipated into the water
used to load the dynamometer.
The dynamometer applies load according to the flow rate
and level of water in the casing. An accurate needle valve
controls the flow rate and level. An electronic load cell
measures torque. The engines (available separately) are
supplied pre-mounted on a sturdy precision base plate.
When the engine is initially mounted onto the test bed or
exchanged with an alternative engine, dowels and slots
locate the engine quickly, accurately and reliably. To enable
students to measure air flow, an air-box and orifice plate
are located underneath the engine bed on the trolley.
The instrumentation is mounted on a sturdy frame. The
frame has a single power inlet and several power outlets to
supply the various display units (either those provided as
standard or those provided as optional extras). The
instrumentation and test bed are separate in order to avoid
vibration being transmitted from the engine to the
measuring devices.
The engines (available separately) include an exhaust
thermocouple, dynamometer coupling, hoses and fittings.
TecQuipment can also supply the engines with premodified
cylinder heads and cranks for connection to
TecQuipment?s Engine Cycle Analyser (ECA100 available
separately). Each engine includes a colour-coded fuel tank
with self-sealing couplings. The couplings ensure the
engines can be connected and disconnected quickly and
efficiently with minimum loss or spillage of fuel. For
convenience and safety, the fuel tank can be removed for
filling or for storage in a fuel locker when not in use.
Removing the fuel tank also prevents unauthorised use of
the equipment.
