Turbocharged cars used to be the high powered, exotic, lusted after sports cars. In today's world, they're more common than ever. Downsized turbocharged engines allow for small displacement, but still substantial horsepower, resulting in what manufacturers would like to claim as the best of both worlds: both efficiency and power. But it's not quite that simple for turbocharged engines, and there are real disadvantages versus naturally aspirated engines.
This video will discuss five disadvantages of turbocharged cars, ranging from throttle control & turbo lag, to the efficiency & reliability of forced induction vehicles. The throttle mapping, torque curve, cost, compression ratios, air/fuel ratios, and even sound all have dramatic differences when compared to a naturally aspirated engine. Check out the video for all the details!

To be fair, it's way cheaper to extract more power from turbocharged engine than it is from NA.

Even hybrid turbochargers cheap compared to turbo/supercharging NA engine.

@sethschober4596 2 роки тому
Excellent video, gotta love the immediate throttle response of a good NA v8. Around 7:10 I think you may have a misunderstanding though. I don’t think the lower Static Compression Ratio (total volume at BDC vs total volume at TDC) manufacturers quote for turbo engines will actually hurt combustion efficiency. The reason being, the engine sees total, or Dynamic Compression Ratio (air density immediately before combustion vs atmospheric air density). Even though turbo engines tend to use lower SCRs (e.g., 9:1 instead of 11:1), the air has already been compressed by the turbo before it enters the combustion chamber. I think that would make up the difference. After all, the final pressure and chamber surface temperature right before the spark ignites is your limiting factor for a given octane fuel. In fact, using an intercooler will effectively compress the air further, enabling you to even get a higher DCR with a turbo engine than an NA engine. However, most of what I’ve just said goes out the window if a manufacturer’s tuning program cuts boost at low load to improve fuel economy.
@joopie99aa Рік тому
I think thermal efficiency is mostly a function of the compression ratio (or decompression) during the power stroke. For ideal efficiency, you want the air in the cylinder to be at ambient temperature and pressure at the end of the power stroke. Any additional pressure and temperature is dumped through the exhaust and wasted (a turbo recovers some of that energy for powering forced induction, but that isn't power to the wheels). This is the idea behind the Atkinson cycle: a larger ratio is used during the expansion stroke than during the compression stroke, allowing the air in the cylinder to come closer to ambient pressures and temperatures, leading to greater efficiency. Forced induction and the resulting lower compression ratios do the opposite: the pressure and temperature at the end of the power stroke are increased, so there is more wasted energy, so lower thermal efficiency.
@confidentlocal8600 9 місяців тому

Jeremy Clarkson once showed the difference between NA and turbo lag on _Top Gear_ by racing a minivan against a Mitsu Evo FQ400. Both were in 6 gear at a matching speed, and both floored it. The minivan pulled away whilst Jeremy was sitting there waiting for the turbo to spool.

That's not lag, that's boost threshold. The Evo is obviously losing to a short geared minivan if it is before it even has a third of its torque in a gear that gets it to the much higher top speed

As a fellow ME ( PhD in 85) who has built 5 turbo installations from scratch I will generally say your videos are pretty good. & granted pressures are higher as you said but you forgot one big fact. Gas runs by burning ( unless detonating) & diesels run by explosion. Big difference with regards to shock loading the engine components!
@nthgth 2 роки тому
Could you explain? Seems like they both combust, creating pressure, pushing against a piston. Where's the important difference between burning and exploding here?
@thejoker6243 Рік тому
and what? it's not like all turbos use gas while all naturals are diesel, or is it? no idea what your point is about
@fishgeralding9224 Рік тому
@@nthgth a gas engine uses spark, at a specific moment, to ignite the charge. If the initial compression ratio is too high, it ignites the charge due to the heat created by compression, too soon. This results in the charge detonating before the piston reaches top dead center where it's supposed to fire. Therefore you have pressure trying to push the piston down, on it's way up. This, at the least results in "spark knock". At the worst, it "hand grenades" the engine. A diesel engine relies on compression detonation, through compression, to fire ,or detonate the charge. That's why a diesel can handle boost at much higher compression ratios.

Hi Jason! My huge thanks at first place for your wonderful videos. I need to ask you a question that has been nagging me for a long time now. Why do we need a rich mixture to reduce the in-cylinder temperature? Why can't we instead go for a lean one? My understanding is that the extra fuel that goes into the cylinder absorbs more heat to vaporize but that also means that more energy is now available for combustion which will lead to greater in-cylinder temperatures. Or the other case could be the fuel escaping from the cylinder without burning or partially burnt fuel leaving into the exhaust leading to greater HC and PM. So why would you ever want to inject more fuel to reduce the in-cylinder temperature? Why wouldn't you simple go for a lean charge instead?
@yanb1981 2 роки тому
imagine engine is already running hot, peak thermal efficiency, once you reduce fuel and go lean temps jump significantly. result= more heat creates detonation, fried rings, damaged piston etc. Lean mix at max operating temp is recipe for disaster. Ask anyone who's blown and engine doing so (I have recently, on a small scale). Rich mixture is crucial to avoid the potential damage caused by heat, and no adding more fuel doesn't worsen the condition bc ratio of the fuel is greater. Simple test, buy a carbed 50cc scooter, install a 70cc bore kit, keep stock jets (no increase in fuel) enjoy for a little while. Then have it blow at WOT. gaurantee it will happen, but no better way then to test it for yourself :) lol
@surendharank3128 Рік тому
The reason is there will be unburned oxygen. High temperature oxygen will react with metal causing degradation. So, always, air fuel ratio is slightly fuel rich. This is the case everywhere, like gas turbines, rockets. I don't know why the mixture is more fuel rich than normal at the start.

I drive a 2018 wrx, and I can definitely say the throttle is basically an on/off switch. It's very difficult to drive the car "normally". The slightest pressure and you're hitting boost. Many modern cars have a more sensitive throttle than I'd like, but the wrx takes that to the extreme. My previous car had a mechanical throttle that gave you tons of room and a smoother response. I do like my car, but they could have tuned that throttle to be a bit less sensitive.

I’m in the middle of deciding btw a Mazda Czech 5 turbo AwD or possibly a Subaru Forester sport trim. I was watching your video about turbos? Do you think I should shy away from another tubo charged vehicle. I haven’t had any problems with my st. But with my wife’s Nissan Juke 15 the EGR value needs to be replace with only 50k miles. The dealership want over 2k to replace this because the engine has to come out of the vehicle in order to be replaced. The told me that my wife doesn’t drive aggressive enough and it probably why it when bad.
