ping2ping: Please I see mostly in Volkswagen products having Turbo Charged Engine and I wonder, what exactly is a turbo charged engine?

I notice that turbo charged engines produces higher power that their non turbo engines. For example you will see 1.8L turbo engine producing about 140hp while a 2.0L engine will produce 120hp.

Can the turbo engine be easily fixed by most Nigerian mechanics?

Thanks for all your contributions

Area_boy: Trac just made everything sound much more complicated than it actually is. I don't think he needs to know torque to power formula.

In its simplest explanation, a turbocharger is a device that forces more air into the engine and improve its efficiency and thereby increasing output power.


If you think of how the conventional engine works. air mixed with fuel gets sucked into the engine and compressed before burning to give power. Turbo give you more air in the engine.


Someone correct me if im wrong here but I think most (if not all of them) turbochargers in car get their power from the exhaust stream?

But OP. all you need to know is my first line of reply. except you are thinking of getting a turbocharged car then you might want to do some more research on the topic if its an older model car. With a brand new car, you should have no problem worrying about how your turbo works

icemann: Any mechanic that can't fix or change a car turbo should not hold a spanner or look under a hood.

ping2ping: @Trac
Thanks for that response. I always thought that the engine might be difficult for ordinary Nigerian mechanic to handle well. I don't have so much money to go to expensive auto technicians

JUO: @Trac: please put me through. i was thinking turbo will increase horse power?

sultaan: Yeah Trac light is on now .

Turbo is one little expensive gizmo added to some small engines to give it some ump like bigger engines.

Turbo engines need about 1 litre of engine oil extra to lubricate it so if your mechanic added the usual 4 litres at service you may be very low at next service.

A turbo engine is usually about $1600 more expensive than a regular engine.Turbo can be added to any engine but because they cost thousands not really worth it for most

icemann: Turbos are easy to fix. Any mechanic that can't fix or change a car turbo should not hold a spanner or look under a hood

Trac:

You are correct, all he needed was the first response. My contribution was to supplement the youtube links in the first response. Without the arithmetic expression, the content could still be understood plus economic considerations were factored into my response. The OP had no problem with the content.



The content is not complicated. Anyway, as you stated it's a gizmo. Blunt truth! In actuality, it's a gimmick when you understand how heat-engines express themselves. There is no increase in efficiency. It's just a hyped perception for us to manage-with and accept the huge inefficiencies.



Sincerely; "turbos" (the vehicle) do NOT run on air. It is also out of the realm of the mechanics. The formulation (or configuration) of the fuel in liquid-state sold in Nigeria does not lend itself favourably to such sub-systems. It has nothing to do with the mechanics but operational. This is further exacerbated with the fact that most of such engines require a state-of-health to be at least near-optimum. It's one headache that can be avoided.

icemann:


I disagree with you. If you agree that turbos increases torque then how does it not improve overall efficiency? If more torque can be gotten by turbos, you can have a smaller engine with high torque and a higher gear ratio. You save weight by using a smaller engine and you can use more gears in the box.

gbonsalifus:

Very good answers have been given already. But to make the answers as simple and direct as the question for just anybody:
(a) A turbo charger is a very simple device like a small turbine that's mounted on the exhaust manifold/system of an engine. Its function is to force in more fresh air into the combustion chamber for better burn/pressure, hence, more power as u rightly stated.
(b) U dont need to bother about its reparability as a turbocharger is as simple as your car radiator and fan system. It can be managed by any fairly good mechanic.
Just to add, the charger is mounted on the exhaust system so that the high pressure exhaust gas from the engine can drive/spin the turbine. If it is driven by something else (like an electric motor, sometimes), it is called a super charger.

A turbocharged or supercharged engine is more economical than a non turbocharged one. Now, the problem is with the definition of fuel economy and fuel efficiency.
Auto enthusiasts use the two expressions interchangeably but in engineering, there is a little difference. While Economy puts the cost/price of achieving the output into consideration, efficiency only considers the unit ratio of input to output of a particular system like 'fuel' for example. Can't say it all here, I should write about this on my blog soon.
for those who can comprehend, consider a Nissan GTR vs Audi R8. Also, a Bugatti Veyron vs Koenniseg Agera in relation to this topic Efficiency vs economy'.

If its more economical then my friend why haven't car companies adapting this technology in their cars?


So you want blog traffic by putting spin on a simple definition. Don't let me spoil your garri.

Ikenna351: Peugeot has dropped V6 engines, both petrol and diesel engines.

Now, Peugeot launched recently their new 1.6 L, 270 bhp turbo petrol engine in their newly lauched RCZ R. Yes, 1.6 litre engine, producing 270 hp. And guess the car fuel consumption? 44 mpg on highway, with 270 bhp. Impressive!

ping2ping: It's now very clear that Turbo is used to increase the power output of the engine rather than increasing the engine capacity.

Now, is turbo charged engined easy to maintain by Nigerian mechanics? I ask this question because not everyone can afford to take their cars to dealers or to expensive garages. Most of us patronize these so called road side auto technician who as a matter of fact are trying considering the educational background of most of them.

Does turbo charged engines require more expertise to maintain than regular engines?

Allo contributions will be highly appreciated

Torque != Efficiency
That alone renders the whole question as misplaced. Regarding your question and context, I can’t figure the relationship. If you know it, please give me the mathematical expression with the associated principle(s)/law(s) and I will work with that. However, I do know where you are coming from; a perspective fashioned by mainstream media. I will take the extra length to define “constraints” for the purpose of this objective. It will be lengthy but quantifiable in details. Torque by definition is the integration of force in distance (Force * Distance) or mass in acceleration (Mass * Acceleration) and efficiency of a plant has to do with the ratio in work output relative to the heat input of the working fluid.* Efficiency in this discussion is subdivided into three isolated conditions. Thermal efficiency (in a heat engine**) is the fraction of the heat input that is converted to net-work

The second law of thermodynamics – Claucius: It is not possible to construct a device that operates in a cycle*** and produces no effects besides the transfer of heat from a lower temperature body to a higher temperature body.
The second law of thermodynamics – Planck: It is not possible for any device that is dependent on a cycle to receive heat from a single reservoir and produce a net amount of work.

No engine or system with a hot exhaust is efficient. None! It is how reversible in process the system is that matters. The internal combustion engine is a closed-system and it is greatly dependent on how reversible**** it is. The less reversible, the more the inefficiency. It has nothing to do with high torque equating efficiency. The turbine is a sub-system. It has nothing to do with the closed-system; for a closed-system does not interact with any of its surroundings besides its immediate surroundings. Any expansive-medium**** that has the addition of heat to it will never exceed the temperature difference in reciprocal to the highest temperature in percentage. That is E = [((Th – Tl) / Th) %]. This is known as the Carnot efficiency. As long as the addition of heat is to the expansive-medium, it will never exceed that efficiency. Furthermore, no heat engine cycle can ever be completed without losing some heat to a lower temperature sink. This is the root to the efficiency and your fuel economy. You want minimal heatloss to increase overall efficiency. The less heatloss, the closer you get to 100%. The maximum theoretical efficiency gotten from a gasoline (spark) engine is 25%. You’ll be lucky if you ever get such efficiency. In similitude, it is as an candidate took an exam and made 18%. That is an epic fail. You’ll be shocked the efficiencies of today’s engines. Things did not get better. Also, the higher the number of cylinders, the less efficient the system will be due to irreversibilities. Irreversible****** processes are higher.

Don’t fall for the horsepower-torque misconception. In a partial differential mathematical expression, you can freeze a variable and begin to work on the corresponding variable (torque/economy). I hope you caught my drift there. It is wishful thinking that things will change without a heavy price. There is new technology on the shelf. It’s not coming now. At the moment, a test-run is being conducted; a vehicle has been released to forbid you from servicing your own vehicle. You’ll be breaking copyright laws. If it succeeds, then it becomes the norm [moving-forward]. If not, then something else. It’s a business and they want to remain in it
