The Truth about Tier 4f
Tigercat FPT engines meet stringent Tier 4 emission levels without the need for variable geometry turbochargers, an EGR system, a higher capacity cooling system, an intake throttle body or a diesel particulate filter. The engine series offers improved reliability and lower long-term maintenance costs. Most of the new emission equipment is found in the exhaust or after-treatment system. The key is the selective catalyst reduction (SCR) which converts the harmful components of the exhaust gas stream into water, nitrogen, and carbon dioxide. Learn about the advantages of the Tigercat Tier 4f solution in this short but very informative video.
