Caterpillar Launches Tier 4 Land Well Service Engine

Engine available for order in 2014; controlled by single advanced ADEM A4 engine module

Posted on May 6, 2013

Caterpillar Global Petroleum has launched the Cat 3512E (HD) high-horsepower land well service engine. The U.S. EPA Tier 4 Final engine is offered with ATAAC and SCAC configurations in two power ratings: 1678 bkW at 1800 r/min and 1864 bkW at 1800 r/min. The engine will be available for customers to order in 2014.

Manufactured in Lafayette, Indiana, U.S.A., the Cat 3512E (HD) Tier 4 Final engine will meet emissions standards with a NOx reduction system (NRS) and diesel oxidation catalyst (DOC). For ease of installation, Caterpillar said it will provide customers with a turnkey aftertreatment solution and various engine attachments. Customers will also have the option to purchase the engine with air cleaners, aftertreatment and an exhaust system installed from the factory.

The engine will be available with a single advanced ADEM A4 engine control module, Product Link for engine monitoring, optional engine mounted transmission cooler, and optional air shut-off valve, Caterpillar said.

The new engine also features up to a 5% improvement in fuel efficiency and increased ambient and altitude capability compared to the 3512C (HD) Tier 2 engine. In addition, maintenance intervals can be improved with factory installed air cleaners and other enhanced engine components, Caterpillar said. Since the engine uses a NRS configuration, there is no need for additional fluids, such as diesel exhaust fluid (DEF), in order to meet emissions regulations.
