What are the disadvantages of turbojets?
Turbojets have poor efficiency at low vehicle speeds, which limits their usefulness in vehicles other than aircraft. Turbojet engines have been used in isolated cases to power vehicles other than aircraft, typically for attempts on land speed records. When you add a turbocharger to the engine, you are adding another layer of mechanical complexity to just an ordinary engine. So more things can go wrong, thus it requires maintenance more often. And subsequently make the turbocharger engine more expensive.
What is the main drawback of a turbocharger?
Disadvantages of a Turbo Engine Well, more power means more energy output per second. This means that you have to put more energy when you use it. So you must burn more fuel. In theory, that means an engine with a turbocharger is no more fuel efficient than one without. In most cases, a well-maintained turbocharger can last between 100,000 to 150,000 miles (160,000 to 240,000 kilometers) under normal driving conditions. With proper care and adherence to manufacturer guidelines, some turbochargers have even been known to exceed 200,000 miles.Another misconception is that turbochargers drastically reduce engine lifespan. With proper care and maintenance, a turbocharged engine can last just as long as a naturally aspirated one. Some believe turbochargers require extensive engine and surrounding component modifications, but this is not always true.All Turbos Are Not The Same. Cheap turbos are just that cheap ! It’s important to remember that if a turbocharger or component is priced cheaply, there’s a reason – it’s been manufactured to a price point, and not necessarily to the ideal specifications or quality standards your vehicle requires.
Which is better, turbo or non-turbo?
Turbocharged engines are generally more fuel-efficient, especially when driven conservatively. By compressing more air into the combustion chamber, they extract more power from every drop of fuel. This efficiency makes them appealing to eco-conscious drivers and those who want to save money at the pump. The advantage of turbojet engines is the ratio of their weight to their highest achievable output. Because of this, these engines are used in particular in the military industry and they are popular in the experimental sector.
