VVT system - front viewIn the quest for optimized performance, fuel economy improvements, and reduced emissions, automotive companies are investing in variable valve timing (VVT) technology for internal combustion engines. With proven experience deploying flexible, state-of-the-art VVT test stands, Wineman Technology is your go-to test system integrator for automotive, transportation, and other engine markets.

Cost-Effective VVT Testers Using Commercial Technology

Tier 1 manufacturers and suppliers of automotive components turn to Wineman Technology because:

  • We have the proven expertise to create variable valve control and variable cam phasing solutions that meets your exact engineering needs with flexibility for future development
  • We use commercial off-the-shelf (COTS) technology for faster design and deployment, flexible configuration, and easy repair and maintenance
  • Our INERTIA real-time test and control software is incredibly powerful and flexible, giving you the ability to make changes on the fly and easily program tests on your own. It allows customers to take field testing data and reproduce the results in a controlled environment.

Past Projects for VVT Testing

VVT systems are often developed in parallel with other components. At Wineman Technology, we build test stands that can control phase angles, oil and pressure valves, and motors to evaluate cam-phasing systems even before the engine or ECU design has been completed.

  • VVT Performance Testing
    Using different engine speeds and system oil pressures, the VVT system is evaluated for parameters such as response time when moving between two phase angles. By measuring the system’s response to the engine’s dynamics, resonance and harmonics, the effect on the system’s entire performance can be characterized.
     
  • VVT Endurance Testing
    These testers run the VVT system for long periods of time at varying speeds and phase angles to simulate long-term wear and tear. Higher oil temperatures and dirty oil are often used to intentionally increase the wear on the system.
     
  • Cam Phase Testing
    Our test stands can monitor the phase angle between the cam shaft and crank shaft using the engine sensors or external encoders.
     
  • Head-Only VVT Testing
    For R&D prototypes, our tester can physically drive the engine’s crank shaft without fuel to test the cam phasers before the engine is fully designed. We also build spin stands that can run different engine heads without the actual engine by using a universal mounting setup to test different phasers.
