Why does a Turbocharger only produce boost when the engine is under load?
처리 내용
Let me lead off with an excellent book on the topic: Corky Bell's Maximum Boost . There is a sound treatment of the basics of turbocharger operation in addition to some dated and esoteric applications that are still interesting. For example, I find the discussion of turbocharging different types of carburetor to be of intellectual if not practical interest. To summarize the points called out in your question, here are some of the major aspects of the turbocharged engine that are of interest: The air flow : remember that an internal combustion engine is effectively an air pump. If we're talking about an engine that is operating "under load", we can assume that you've opened the throttle. For example, when rolling down hill, you don't need to hit the throttle so the entire intake to exhaust path is pumping a smaller air mass. However, driving uphill will require you to open the throttle (give it gas), adding air to the intake. This causes the engine computer to add fuel to the mixture. T

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
