A two cycle diesel experiences a power stroke every two strokes, and the primary benefit is a high horsepower per CID (cubic inch of displacement) ratio. Although the two cycle Detroit diesels do not have intake valves, they do have traditional camshaft driven exhaust valves. Unlike a small gasoline two stroke engine, which are familiar to most people, two stroke diesels do not run on a fuel-oil mixture and have an oil filled crankcase like a traditional 4 cycle engine.

The 53 series two stroke diesel was attractive for several reasons, but there are many fallacies surrounding two stroke diesels in general. Modifications to the engine family promised better fuel economy, quieter operation, and more horsepower across the board. The 'silver 53' series was introduced in 1984. The 12v-53 produced just over 400 horsepower, where as the 12 cylinder 71 series produced a minimum 450 horsepower and up to 900 horsepower. This likely because the larger 12V-71 was more apt for applications that required an engine in this horsepower range and could manage the spacial restraints of a long, 12 cylinder engine. The 12 cylinder version is extremely rare and was reportedly only produced for 1965 to 1968 model years it is rumored that under 25 of these engines were placed into service. The 8 cylinder version was primarily used in marine applications, although it was much less popular than the marine 8V-71. It was offered in 3 cylinder, 4 cylinder, 6 cylinder, 8 cylinder and 12 cylinder configurations. In practice, this mechanical system works well, however, it can prove to be tricky to synchronize the injectors as each bank is controlled by a shared linkage.All 53 series diesels, regardless of displacement, feature a 3.875 inch bore and 4.50 inch stroke.

All Detroit 53 series engines use a unit injection system, wherein the unit injector creates injection pressure is created in the injector body itself via a camshaft-driven plunger in the injector.

A Detroit engine with 159 CID weighs 965 lbs, while a Cummins 6BT engine with a relatively high 359 CID weighs only 975 lbs.

The horsepower-to-weight ratio is relatively low in the Detroit 3-53 engine, especially as the weight of this engine is rather high.

The 3-53 engine has an oil-filled crankcase and does not run on a fuel-oil mixture as is the case with a conventional 4 cycle engine.

When modified, the 3-53 promises improved fuel economy, and can even ensure quieter operation, complete with increased horsepower.

When it comes to marine applications, a two-stroke engine like the Detroit 3-53 offers immense versatility, and can easily be operated in both вЂ“ clockwise and counter-clockwise directions.

The primary benefit of this cycle is the high horsepower per Cubic Inch Displacement (CID) ratio, as a direct result of the high thermal efficiency of the engine.

A two-cycle diesel engine such as the 3-53 undergoes a power stroke every two strokes.

When weighed dry, without any fluids present in it, the engine clocked 965 pounds. The 3-53 engine presents a length of 33 inches, a width of 27 inches, and a height of 35 inches. The starting motor of the 3-53 engine makes use of a 12 V system. The engine also features a cam-operated, clean-tip unit type fuel injector, as well as a full-flow system oil lubrication filter, complete with a 10-degree inclined oil pan. It makes use of a variable speed, throttle-controlled governor. The flywheel and flywheel housing in the 3-53 Detroit diesel engine is SAE No. The engine features a 22-inch, five-blade design fan. The 3-53 comprises of a 12 V, 42-amp alternator, complete with a crankshaft pulley as well as an exhaust manifold. It produces a maximum torque of 205 ft-lbs at 1,800 rpm. The engine offers a power output of 101 horsepower at 2,800 rpm, while it is known to provide a continuous gross power of 70 horsepower at 2,400 rpm. Comprising of three cylinders, the compressions ratio of this engine is 21 to 1. The total displacement of the engine, as suggested by its name, is 3Г—53, equaling 159 cubic inches, or 2.61 liters. The Detroit 3-53 is a two-cycle engine, which features a bore by a stroke of 3.875 by 4.5 inches, or 98 mm by 114 mm. While the вЂ3вЂ™ in the name represented the number of cylinders it featured, вЂ53вЂ™ referred to the cubic-inch displacement per cylinder of the engine. The Detroit Diesel 353 engine, also known as 3-53 was a high-powered diesel engine manufactured by Detroit Diesel Engines.
