If you makeup an air shut down, be sure to make it of heavy duty material. I have seen them sucked in to diesel engines with high damage resulting. Make sure you have a strong spring to hold it shut also. An electronic control engine is not near as likely to "run away". I have seen oil lines to turbos break and "feed" the engine making shut down difficult. This is when an "air flapper" comes in handy. We got to the point where we would not use any diesel engine unless it had a water cooled turbo. There was just too much risk of fire if the oil line to the turbo broke. Some model diesel engines that had "Jumper Lines" (from one injector to the next one) under the valve cover had problems for a while when some how the wrong steel was used to make up the jumper lines. The lines would break and the fuel dumped into the crank case. Eventually it started to blow by the rings. You can imagine what happened then. In general, 4 stroke cycle diesels are not as prone to these type problems. The more modern electronic engines have numerous built in safety features as well.
