Installation
The Cat 3516 engine features a 69L displacement and V16 configuration. Its overall size is approximately 11% smaller than competing engines at the same power rating, saving valuable engine room or compartment space.
The single lifting point design ensures safer and more efficient hoisting of the complete engine.
Cost Savings
Optimized combustion and turbocharging deliver approximately 6% fuel savings compared to the previous generation, with even greater advantages under heavy‑load conditions.
Time between overhauls can reach 18,000–25,000 hours, far exceeding most similar products. With long oil change intervals and modular filters and components, maintenance labor time is reduced by more than 30% compared to equivalent models.
Reliable Operation
The Cat 3516 engine delivers industry-leading operational stability. Featuring a heavy‑duty V16 configuration and reinforced cylinder block, it operates with low vibration and smooth running, enabling stable performance at full load for extended periods.
With a proven, reliable combustion and cooling system, excellent environmental adaptability, and an extra‑long service life, the engine boasts a low failure rate and maintains consistent output even under harsh operating conditions.
