The Compression Ratio can be changed without stopping the engine and without altering the combustion chamber geometry by means of a specially designed tilting cylinder block arrangement. Setup is provided with necessary instruments for combustion pressure and crank-angle measurements. Computerized Variable Compression Ratio Engine Test Bed allows to perform experiments concerning this kind of engines. The unit consists of single cylinder, four stroke, Variable Compression Ratio (VCR) engine connected to eddy current type dynamometer for loading. Provision is also made to interface airflow, fuel flow, temperatures and load measurement. Rota meters are provided for cooling water and calorimeter water flow measurement. The test bed includes a stand-alone panel box consisting of air box, two fuel tanks for duel fuel test, manometer, fuel measuring unit, transmitters for air and fuel flow measurements, process indicator and engine indicator.

The flexibility of a CVT with suitable control may allow the input shaft tomaintain a constant angular velocity even as the output speed varies. Acontinuously variable transmission (CVT), also known as a single-speedtransmission, stepless transmission, pulley transmission, or, in case ofmotorcycles, a twist-and-go, is an automatic transmission that can changeseamlessly through a continuous range of effective gear ratios. This contrast swith other mechanical transmissions that offer a fixed number of gear ratios.
The completepower flow within the CVT automatic transmission can be observed:
Primary andsecondary conical disk with hydraulic piston
Idler gearand differential
Input shaft
Planetarygear with hydraulic clutch mechanism
Speed changeby movement of the conical disks.

A robust support pillar fixes to a suitable table or bench(not supplied) with a low natural frequency. The pillar holds a cantilever that holds a model four-cylinder engine.
A bench- mounting model four-cylinder engine that shows primary and secondary forces and moments in reciprocating masses and how to balance them. The model engine has a crankshaft, connecting rods, bushes , pistons and a cylinder block. A separate Control and Instrumentation Unit (included) controls a motor that turns the engine crankshaft. This product is an excellent follow-on from the Static and Dynamic Balancing equipment.
Experiments:
Primary and secondary forces and moments for different crank settings.
