World’s Largest Two Stroke Engine


When we think of two stroke engines, often we imagine smaller motors used in outboards, motocross bikes, and jetskis. However, the world’s largest two stroke engine is 89 feet long and 44 feet wide; the size of a house! The engine is called the Wartsila-Sulzer RTA96-C, and it’s a two stroke diesel engine that is manufactured by Aioi Works in Japan. These enormous two stroke engines are designed to power super oil tankers and container ships. These engines often use a single propeller for simpler maintenance, and despite what people might think, the single propeller design has proven to last for a longer span of time.

These enormous engines consume about 39.5 barrels of bulk motor oil per hour. That means, in the current market, it costs about $34 to power these engines every minute! That’s an amazing amount of oil consumption, but with an engine the size of a house, it doesn’t seem all that unrealistic.
