How does a drive become even more functional?
By testing every component individually.

Investigation of the functional behavior

An engine does not only have to release power efficiently, it should also do this reliably – for as many years and as many kilometers as possible. Schaeffler Engineering therefore tests the functional, friction and acoustic behavior of engines and engine components.

Investigations of the functional Behavior

Geared up for reliability

There are many factors upon which ideal engine performance is depending. Only when all components are working properly the maximum engine power can be supplied.

For this reason, Schaeffler Engineering places a main emphasis on investigations in the area of functional behavior and carries out the following investigations on its test benches:

Valve train investigations

Dragged or fired investigations on a valve train in order to assess the dynamic behavior of conventional or variable valve trains.

  • Analysis of the oscillation behavior of the train drive and of the damping behavior of the valve springs
  • Functional assessment of the behavior of hydraulic valve clearance adjustment elements
  • Functional safety of the valve train
  • Starting behavior
  • Noise behavior
  • Function of the hydraulic valve clearance adjustment
  • Investigation of oil foaming behavior
  • Support for the design and development of valve trains
  • Functional investigations on valve trains with cylinder shutdown
  • Functional investigations on valve trains with shiftable valve train components
  • High speed test benches for dragged motorcycle applications
  • Documentation of valve train and tappet rotation
  • Video recording by means of high speed cameras
  • Functional investigations on our bearing test benches (water ingress and grease leak tests)
  • Investigations on high pressure fuel-injected systems
  • Application of used diesel and gasoline oil

Control and aggregate drives (fired or dragged)

Tests on fired engine test benches, dragged component test benches and a dynamometer for four-wheel drives.

  • Measurement and assessment of the dynamic and acoustic behavior of belt and chain drives
  • Assessment of mechanical and hydraulic tensioning systems
  • Design validation of tensioning and guide rails
  • Improvement of the drive layout
  • Mobile Engineering Service
  • Design support and development of control drives
  • Basic and benchmark investigations

 

 

Cam Phaser (fired and dragged)

Investigations on fired and dragged test benches and on a dynamometer for four-wheel drives

  • Measurement of the dynamic behavior of cam phasers
  • Analysis and assessment of the test results

Oil pumps and Oil supply

Investigations on specially developed component test benches.

  • Measurements in low and high temperature ranges
  • Assessment of the efficiency of oil pumps
  • Assessment of the functional characteristic curves
  • Functional investigations on adjustable and shiftable crankshafts and tandem pumps
  • Documentation of flow rate of all pump types

Cooling Circuit (thermal management module, water pump)

Measurements in low and high temperature ranges on specifically developed component test benches.

  • Investigations on thermal management modules
  • Measurements on conventional water pumps
  • Measurements on controlled water pumps
  • Assessment of behavior, e.g. efficiency, characteristic curves, pressure tests, leakage tests

Hydraulic components

Investigations on specifically developed component test benches.

  • Measurement of the functional behavior of hydraulic components
  • Measurements on piston injection nozzles and non-return valves
  • Determination of flow parameters
  • Investigation and visualization of the dynamic behavior
  • Trials of new construction forms
  • Optimization of existing components
Friction and Tribology

We make things run smoothly

When parts are moving there is friction. Of course, this should be kept as low as possible so that the corresponding components work perfectly and for as long as possible.

As a specialist in the field of tribology, we investigate the friction caused by the individual components, calculate and measure the coefficient of friction and wear, test the influence of various coatings, and adjust the calculation method. Thus, we help you to improve a complete system.

On our test benches, we mainly investigate the following:

In addition, we investigate materials in the MTM2 tribometer and test tribologic systems, lubricants, and surfaces.
