Differences between a naturally aspirated and a turbocharged engine - service and operation

Differences between a naturally aspirated and a turbocharged engine - service and operation – main image

In passenger cars or campers there are gasoline and diesel engines (for obvious reasons most campers get diesel engines) - both naturally aspirated and turbo-charged . Unfortunately - for a large group of drivers, the differences between them (in terms of operating costs, performance and characteristics) remain unknown.

For such a prosaic reason, many of us decide to buy a vehicle, the subsequent driving and servicing costs of which turn out to be far too high for our pocket. Before making a final decision, however, we should learn more about the important differences between naturally aspirated and turbo-charged units .

For some reason, many drivers believe that every gasoline engine (even equipped with a turbocharger and other complex accessories) is easy to build and use, which translates into low operating expenses. Nothing could be more wrong - a modern gasoline unit also causes problems .

Naturally aspirated engine

Even in the 90s , diesel engines without supercharging were very popular. These naturally aspirated gravity engines had little power and torque , and in return didn't require much. Contrary to modern diesel units - their service is almost limited to regular oil, filter and timing changes . Any serious failures are almost always the fault of the user or extreme wear and tear of the equipment. What's more - the injection system of naturally aspirated diesel engines from the past was extremely durable - driving on low-quality diesel fuel (or even heating oil) does not cause any damage. The situation is similar in the case of gasoline engines without expensive accessories - systematic service is enough .

Turbocharged units

Things get complicated when it comes to turbocharged engines . Regardless of whether we are dealing with a gasoline or diesel unit - we have to take into account the advanced design , and thus - higher operating expenses . After some time, the turbine itself will require replacement or regeneration (regeneration cost PLN 900-1500, replacement PLN 1500-5000 ). Turbocharged engines also have a precise injection system that does not tolerate low-quality fuel - even small quality defects can lead to damage . Unfortunately - even a properly used car will demand replacement of the injectors (which will cost up to PLN 1,800 apiece ).

The service of turbocharged units is also more complicated . Additional engine equipment does not make the task easier for an inexperienced mechanic - it also takes up a lot of space under the hood, effectively hindering access to the engine .

Currently, cars and motorhomes are produced almost exclusively with supercharged engines . Their greater efficiency, dynamics, work culture and fuel consumption speak in favor of similar designs. However, they are not as durable as naturally aspirated units .

What are the effects of improper use?
Each of us is well aware of the fact that all devices wear out naturally. Starting with the equipment of the living quarters of a caravan or motorhome, ending with mechanics. The service life of the engine, gearbox and other moving components depends on many factors. Of course, quality and regular, professional service using brand-name spare parts are of great importance. Nevertheless, even new equipment will quickly deteriorate (wear out) if the user makes certain mistakes. Contrary to appearances, you do not need to use the camper outside of paved trails to quickly destroy the suspension - and more. As reported by mechanics, users know many other "effective" ways. Let's start with the most common sin of drivers - aggressive driving on potholed roads . While dynamically passing each corner on our way, we only accelerate tire wear, similar behavior on a devastated artery means strenuous work of shock absorbers, springs, swingarms and all metal-rubber elements. What's more, the entire vehicle frame and the load-bearing structure of the bodywork also work in such conditions - plastic panels will start to crack after some time. Similar results also generate violent shocks - they can violate the tightness of the building. Another important issue that we often forget is the placement of the cargo inside the camper. Many drivers do not pay much attention to this, packing their luggage wherever possible. Instead, place the heaviest packages between the axles - keeping the weight evenly distributed and the load on each axle.
