We mount engines to be tested under load or not under load, according to your requests, and ready to start. Wether these engines are provided by us or by you is irrelevant.

Methods and equipment for measuring the cylinder pressure in piston machines: p-V 1.0 and PicopV 1.0 user`s software for determination of p-V-diagrams with DiaW - Diagram for Windows. p-V forms a p-V diagram from a PC file containing measured values of the pressure and information about the rotary position of the crankshaft, and calculates the work delivered or consumed by the working cycle represented by the p-V - diagram. PicopV and indicator control are controlling continually the acquisition of cylinder pressure and crankshaft position for individual working cycles. PicopV is forming from these data p-V diagrams, evaluates them and calculates an average of indicated work. In the background the PC memorizes by DiaW - Diagram for Windows - data from the MP Computer about the state of the engine, the specific fuel consumption, and the duration of acquisition and evaluation of p-V diagrams.
Engine dynamometers (engine test beds) with additional equipment for the thermal balance.
Volumetric turbine-flowmeter for metering the air flow uptake at combustion engines.
Volumetric turbine-flowmeter with electrical output and optical display for metering the heatflow in the radiator.
- self-supporting bed,
- no transfer of torque to the ground
- rapid fixation of modules and additional equipment in any axial position without drilling
The modules executing torque on each other consist of electric motors with a high torque transmission. They are secured by strong clamping elements on the test bed. Their axial position is adjustable.
The removable protection grid protects only against accidental contact to rotating parts under laboratory conditions.
Solid axially movable protection covers are avaiable if parts might detach and fly away.
Modular equipments for technical training at engines under realistic operating conditions: under load at the engine dynamometer.
Applications depending on scope of delivery:
torque, power = f(speed),
specific consumption sfc = f(speed, power)
(gravimetric, selectable automatically).
Above tests can be carried out in different ways: conventionally or supported by the test bed's MP Computer or with automatic documentation by directly printing or by PC
thermal balance (PC required),
real function of a transmission
(automatic transmission only with PC),
p-V-diagram (PC required).
Functions of engine and engine control depending on the load may be demonstrated by using motor analysers, exhaust gas analysers and further measuring instruments.
Model-specific error-switch boards are extending the demonstration varieties and are enabling a practical error diagnostics.
Comparison of different engines under a certain aspect within one lesson.
