Re: 8v71 by BUBBA THE BUS TECH
Post New Message Part two, lecture two,;) Detroit 2 strokes over fuel when running cold at idle. To fix add load, add heat, shut off. The older style engins with an automatic can be loaded by just dropping into gear. Increase RPM to add heat and load per stroke. The problem with over fueling is that as you run the engine cold the govener adds fuel to maintain speed. This means some is not burning, thus extra fuel going into oil and out tail pipe. The curent engins from virtualy every manufacturer shut off half the engine to increase load on the rest of the cylinders. To make it worse the 8V71 will over fuel in realy cold weather imediately when falling to idle. The best thing to do is to not idle, warm up quick by not turning on interrior heat etc, When you stop, shut it off. Most transit systems that ran this engine instructed drivers to shut them off when at no more than normal operating temp and going to be idling 20 seconds or more.
