Changing Firing Order in a 4 Cylinder Car
처리 내용
Surely, to get a Subaru (or any true boxer engine) to run in this kind of configuration is relatively easy. Bear in mind that you are talking about an engine with two horizontally opposed cylinder heads and a four stroke so for each revolution of the camshaft, there are two revolutions of the crankshaft. Each piston hits it's "top" of it's travel twice, once after it's compression stroke and once after it's exhaust stroke. In usual four stroke applications, one piston will be on it's compression stoke, one on it's combustion stroke, one on it's exhaust stroke and one on it's inlet stroke. Cam timing events are set so that the exhaust valve is open during the exhaust stroke and the inlet valve is open on the inlet stroke. During combustion and compression, they're both closed. With me so far? Now, look at an engine like the Alfa Romeo boxer engine and you'll notice that it has two timing belts. Imagine what would happen if the timing belt was fitted incorrectly such that the timing mark

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
