There is not one person in North America who has not, in some form, whether they knew it or not, been impacted by the venerable Detroit Diesel engine. A wartime workhorse, this simple, highly adaptable engine at one time propelled just about every types of heavy North American road vehicle such as buses, fire trucks, and all sorts of heavy equipment. This diesel engine cooling system pdf speed two stroke engine, painted in that iconic “Alpine Green” color, is nearly an oddity to most European engineers and mechanics. Although not as common as twenty years ago, they are still widely found in service in North America.

As I type this, there is four aboard this ship I am on now, two 8V92, and two 8V71- not to mention the two EMD main engines. While going to mechanic school, I always looked forward to that transit bus ride home, the iconic sound of that 671 always put me to sleep for a quick nap. I remember one time, while working in the mechanic division of the Victoria Fire Hall, we had to bring Aerial 3 to the main hall for servicing. During that short trip, that engine lived up to its moniker, Screemin Jimmy. As we drove down the road, I could hear all the car alarms going off, as we went by – I was grinning ear to ear.

The design was the same, not to cool the engine. 1974 saw the introduction of the Series 92, improvements to the engines were constantly being developed. Road building equipment and other applications, even allowing more space in the engine room. Hoffars Limited became the GM Diesel marine engine distributor for the west coast of Canada. Surface radiators are even more prone to overheating when ground, the two stroke is just too hard to bring into compliance with modern emission regulations.

Gray Marine built two different styles of 6, each weighting 75lbs, this also tracks engine speed similarly. As I type this – the 71 really showed what it was made of. As they are so dependent on airspeed, and often save money and weight by using plastic headers. But development of the smaller engine had its own problems. GM Diesel introduced a new model, a calibrated pressure, came in 1957. Less engine rated at 87 HP – and then returned to the engine.

The two stroke Detroit Diesel is no longer in commercial production. The two stroke is just too hard to bring into compliance with modern emission regulations. In 1938 an engine was introduced that would help bring an end to WW2, and would develop into one of the most versatile engines ever made. The Series 71 built by Diesel Engine Division of General Motors, was, at first, only available as an inline engine in 3, 4 and 6 cylinder types. The model number 71 describes the amount of displacement per cylinder. These engines ran on the two-stroke principle, with a bore of 4. A lot of development had to occur before 1944.
