Diesel Engine Runaway - What is it?
처리 내용
Since the diesel has no physical throttle, power is controlled by limiting fuel. Air is always available so any unintended, un-metered fuel will cause the engine to increase rpm and power output. The most common sources are blowby oil and oil leaking from a worn turbocharger, these then pool in the intake manifold. This engine oil gets pulled into the engine during low load high rpm operation. It usually starts when the engine is revved up with no load, once a runaway starts the high air flow rates in the manifold continue to pull oil from the pool. While engine oil does not burn as well as diesel it will burn well enough to reach redline rpm in a warmed up engine. Preventative maintenance involves inspection and repair of worn parts with particular attention to piston rings and turbos. Design prevention should focus on eliminating areas in the intake that allow pooling so that incoming oil is processed a little at a time. To stop a run away engine plug the intake or open the compressi

Hello! I have not driven my car for a month and now have this noise. It is a 2016 V Jetta and normally in great shape. The noise is in the background and sounds like something soft is rubbing against something. It picks up at 10 mi/hr or so and then stays on…Thank you! https://global.discourse-cdn.com/cartalk/original/3X/3/f/3f6ae6628ea80cf8d6b1899d0b2392d868545516.mp3

Power seat - Whenever vehicle is started or shut off and the seat slides forward of back, the power seat makes an annoying, obnoxious noise… I thought something was stuck in the track but now I think it’s the motor going out. Guy at the local dealership said it just needed grease. He appears to be incorrect. Any thoughts? Thoughts?

A buddy and I were trying to replace his right front wheel hub, on his 2008 Chevy Impala LTZ. He described the engine size as 3900, I would think that means 3.9 liter, although I didn’t know there is a 3.9, I only know of the 3.8 liter and 3,1 Liter. One of the mounting bolts is so tight that the socket would not keep a grip on the bolt head, no matter how hard we tried to force the socket onto the bolt head. We had tapped on it as best we could with a hammer and metal rod, we heated the area with a torch, no luck. Of course, very little access to this bolt head, so impossible to use an impact
