Why does diesel engine have redline much lower than petrol engine redline?
처리 내용
In Short its based on low burn rate of diesel plus the longer stroke of the diesel engine. First you must understand the difference between these engines, the diesel works on purely compression of fuel , heating and generating bang to produce power, the gasoline on the other hand is natively twitchy and needs a spark to explode and produce power on its own. That said, Think of the petrol engine as a cheetah, it has lightweight bones and has a streamlined body thus is very fast but is not powerful enough to kill a lion or a rhino. The Diesel engine is like an elephant, its slow and has a lot of strength, but needs heavier legs to support the huge body mass thus it cant run as fast as the cheetah but has a lot of strength. By strength of the elephant I mean torque in the engine. The petrol engine natively combusts so it does not need heavy duty parts to withstand the explosion, yes you are compressing the fuel but its not nearly as much as the diesel, that is why 100cc motorcycles rev li

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
