The rebuilt Caterpillar G3516J is a powerful natural gas engine designed for industrial applications such as gas compression, transmission, and petroleum operations. This refurbished model offers a high output configuration with up to 1500 horsepower at 1400 RPM, ensuring strong performance in demanding settings. It features ADEM III ignition and NOx sensing technology to maintain optimal fuel efficiency and emissions control, with emissions rated at 0.3G/BHP-HR NOx and meeting EPA stationary exempt standards. This engine includes water-cooled exhaust manifolds and dual large vibration dampeners for improved stability and cooling efficiency. The unit comes equipped with a 24v charging alternator and a simple oil filter with right-hand service access, alongside a standard oil pan and C-channel rails for secure installation. It does not include a panel, harness, or starter, which will need to be sourced separately. The absence of a jacket water heater and stub shaft simplifies its maintenance and integration into existing systems. Ideal for continuous duty operations, the G3516J ensures reliability and durability with a compression ratio of 8:1 and effective air/fuel ratio control. It is the right choice for those seeking a robust and efficient natural gas engine in refurbished condition, capable of supporting industrial applications with notable power and operational efficiency.
