The 60 Series Detroit Diesel engine is an in-line six-cylinder engine with electronic engine control and overhead cams. The engines come in 11.1, 12.7 and 14.0 liter options.
The 60 Series Detroit Diesel engine is typically used in Class 8 trucks, which include cement trucks, tractor trailers, dump trucks and similarly sized large road trucks. Typically, this designation applies to trucks over 33,000 pounds. However, the engine is sometimes used in non-automotive applications. Examples of this include the engine's usage in commercial marine products such as large boats as well as industrial applications such as power generators.
The engine is rated to produce up to 515 horsepower at 1200 rpm via a 5.24-inch bore, or cylinder diameter, and a 6.61-inch stroke, or distance travelled by the piston per revolution. The engine also features a one-piece piston, which contributes to the relative high compression ratio of 17 to one. This yields a number of benefits including a reduction in piston friction, improving oil efficiency while minimizing soot loading.
Detroit Diesel has also reduced emissions by introducing Exhaust Gas Recirculation. This system cools the exhaust using water and then re-circulates the air into the engine. In addition to the emissions reduction, the cylinder head of this system helps move air around the engine.
The engine requires oil changes every 30,000 miles. It is capable of starting and operating in temperatures as low as 40 degrees below zero Fahrenheit.
