Caterpillar is the largest vertically integrated manufacturer in the world. As each new family of engines moves us forward, it also sustains the advantages learned from decades of manufacturing, testing and product support.

CAT® TIER 4 TESTING AND VALIDATION The testing and validation program of Cat® Tier 4 engines has been the largest in Caterpillar history. This industry leading engine validation program ensures that all new Cat engines deliver reliable performance from the first day on the job.

Multi-segment, multiphase validation of prototype, pilot and support machines conducted in a wide variety of the most demanding applications.

Reliability has been proven with millions of operating hours on thousands of products.

Developed a new manufacturing plant process designed to improve production and quality.

Advanced power system simulators provide extensive modeling, analysis and testing.

Next generation simulation techniques enhance cooling system design, increase electronics capabilities and optimize power train integration.


No one knows more about systems integration than Caterpillar. From the concurrent design of components, systems and the electronics that control them, we are always looking to the future: What specifications need to be met? What types of conditions will occur? What will be the most effective way to manufacture what we design? What kind of support will be required?

And, then, when we answer those questions, we field-test with our customers. This is the most critical step: integrating product with application needs and customer expectations.

This approach is how we ensure that Cat Tier 4 products deliver working advantages that are real, measurable and sustainable over time.
