Thermal Cycling Testing

Exposes engine to extreme thermal cycling in order to validate engine sealing systems (for oil, coolant, and combustion gas) and engine structural components. Chiller systems may be used to flush engine with chilled coolant/water mix at temperatures down to -30°F.

Fatigue Testing

Evaluates an engine's robustness to structural fatigue from repeated mechanical loading at high engine speeds and loads. Engine is monitored for structural fatigue of any of its' components.

Road Cycle Simulation

Evaluates durability and reliability of an engine running under simulated customer driving conditions. Testing includes variable engine accessory loading (AC compressor, power steering pump, alternator, etc.). Monitor for failure modes associated with deposits, wearing, and engine system/sub-system interactions, as well as engine functional degradation measured by changes in idle quality, oil consumption and power loss.
