Tier 4 Regulations Prompt Wheel Loader Enhancements

摘要

Anyone who manufactures, purchases or uses construction equipment knows the fourth phase of nonroad EPA air-quality regulations hit in January for engines larger than 175 horsepower. Compared to Tier 3 levels, Tier 4-Interim standards require a 90 percent reduction in PM and a 50 percent decrease in NOx. Some companies, such as Case, Caterpillar, Deere and Volvo, took advantage of World of Concrete and Conexpo venues to unveil their Tier 4-1 solutions. But others have yet to officially introduce their cleaner-burning equipment.
