Engine Characteristics
The 6-71 is a six cylinder engine, which are "inline" or in a straight line. This type of engine is commonly referred to as an "inline six." The 71 refers to the displacement per cylinder which is 71 cubic inches. The firing order of the engine, or the order combustion occurs in which cylinder, is 1-5-3-6-2-4. The engines compression ratio is 18.7:1 with a 4.250 bore and a 5.00 inch stroke. The engine weighs 2185 pounds and is 54 inches long 29 inches wide and 41 inches tall. At 2100 Revolutions Per Minutethe engine is capable of producing 230 horse power, and 172 kilowatts.

Engine Operation
The 6-71 is a two stroke diesel engine. Air is provided to the engine via a supercharger. However, on some models of the 6-71 both a supercharger and a turbocharger can be utilized. Fuel is proved by six, Port and Helix fuel injector pumps, or Jerk pumps. The amount of fuel injected into the engine is controlled by the governor. The governor senses the revolutions of the supercharger to control the amount of fuel injected into the cylinders. More fuel is added for faster speeds and the amount of fuel is lessened when the speed of the engine is reduced. Ignition of the fuel occurs when the piston compresses the fuel-air mixture to a point that it reaches a temperature to combust. The timing of the engine or the order in which fuel and air are added or removed, is controlled by an engine driven camshaft. Depending on the application of the engine, boat or truck, the engine can be water or air cooled. The engine has its own cooling liquid called Jacket Water, the two options for cooling are to cool the Jacket Water. If the engine is in a truck or land based operation then the Jacket Water is cooled by air through a device like a radiation in a car. In a boat an alternative method of cooling is available, which is water cooling or to take the cool water around the boat and pass it by the warm Jacket Water in whats called a heat exchanger.
