The Detroit Diesel 8V92 Turbocharged Engine Overview

The 8V92 engine represents the pinnacle of Detroit Diesel’s two-stroke design evolution, delivering exceptional power output in a compact package. The “8V” denotes eight cylinders arranged in a V-block configuration, while “92” signifies 92 cubic inches per cylinder—resulting in a total displacement of 736 cubic inches (12.1 liters).

When turbocharged, the 8V92 can produce between 400 to over 600 horsepower, depending on its configuration (intercooled, aftercooled, or marine versions). These engines are widely used in commercial marine applications, power generation systems, and heavy-duty vehicles due to their rugged construction and straightforward serviceability.

Turbocharging dramatically enhances engine performance by forcing additional air into the cylinders, allowing more fuel to be burned efficiently—thus boosting power while reducing exhaust emissions and fuel consumption.
