Caterpillar’s 3600 PEEC Locomotive Governor (Programmable Electronic Engine Control)

Abstract

Caterpillar Inc. recently introduced the 3600 Series medium speed, 280 kW/cylinder diesel engine to its product line. Offered in 6 and 8 cylinder inline and 12 and 16 cylinder vee configurations, the 3600 Series engines will be used for marine, electrical power generation, industrial, and locomotive applications. Caterpillar has also developed a microprocessor-based digital electronic control to meet the applications of these engines. The control system can be tailored for many applications; however, this system was developed primarily for locomotive use. The PEEC (Programmable Electronic Engine Control) locomotive speed and load control governor provides minimum fuel consumption and increases productivity of locomotives in both mainline and switch yard service. This paper describes the PEEC locomotive system as applicable to 3600 Series engines.
