Fuel efficiency: Because turbochargers give your car extra power without increasing the size of the engine, they're typically more fuel-efficient than larger engines.
A turbocharger typically helps a car get better gas mileage because a smaller engine can be used to get the same amount of performance. Expect a turbocharged engine to be about 8% -10% more fuel efficient that the same engine that is not turbo equipped.
Using a smaller, turbocharged engine can lower fuel consumption by 2 to 6%. This saves you money and reduces your impact on the environment.
No. today's turbochargers are designed to last the lifespan of the vehicle. The truth is, boosted engines require the same amount of maintenance and care that a naturally aspirated engine does. Does a turbocharger decrease the life of an engine?
Meanwhile, if you own a turbocharged car, there are a few things you can do to maximize your fuel economy: Accelerate gently, but not too slowly; you want to build speed quickly enough to let the transmission shift to higher gears. Keep your highway speeds moderate and use cruise control when possible.
Cons of a turbocharged engine
Affordability: Cars with turbocharged engines are typically more expensive than vehicles with standard engines because may need to use premium gas in your car. Reliability: Turbocharged engines may not be as reliable as standard engines. Engines with more parts have more that can go wrong.
For all turbo petrol engines 95 octane petrol is recommended.
Turbos are designed to last the lifetime of the vehicle (or around 150,000 miles); however, it's possible for them to wear out over time depending on how hard you drive the car and the original build quality of the turbo.
Benefits of a turbo engine
They have greater power density and they are more efficient, the latter of which might mean more to more people. Basically, a turbocharger is connected to an engine to give it more power. This allows smaller engines to put out more horsepower and torque than they ordinarily would.
The longer you drive your car with a blown turbo, the more damage the engine will have and therefore the more costly it will be to repair.
The turbo itself doesn't save gas, but using the smaller engine does. Turbos are often used together with direct injection. Direct injection shoots computer-controlled squirts of fuel into the combustion chamber inside the engine cylinders. The high pressure and precise control produce more thorough burning.
A turbo works by forcing more air into the engine, with the amount of fuel being injected in increasing correspondingly, increasing the strength of the combustion, and producing more power.
Turbochargers provide additional horsepower to your petrol-powered engine. They do so by increasing the amount of air and fuel that enters each combustion chamber. Meanwhile, diesel fuel burns at a lower temperature. That causes it to create more exhaust gas, but diesel engines also have higher compression ratings.
Engines equipped with a turbocharger(s) will consume more engine oil than normally aspirated engines (non-turbocharged). The additional oil that is consumed in a turbocharged engine is mainly due to the turbocharger lubrication requirements.
Once the turbine reaches speed, the turbo kicks in and the car's power and speed increase.
Is a turbo engine better than a normally aspirated engine? Yes, a turbocharged engine is better than a normal engine in terms of performance and efficiency. A lower capacity turbo engine can produce the same amount of power as a higher capacity NA engine.
The turbine in the turbocharger usually spins at speeds between 80,000 and 200,000 rotations per minute (rpm) — that's up to 30 times faster than most car engines can go. And since it is hooked up to the exhaust, the turbine also runs at very high temperatures.
The vehicle can run without an efficiently functioning turbocharger, but it will perform poorly, and your decision could possibly have dramatic repercussions. If the issue is an oil supply or internal component-related problem, complete failure is imminent.
Extreme exhaust heat is what powers the turbine side of the turbocharger, and over time, 2000° temps will take a toll. Prolonged exposure to that kind of heat will eventually kill anything, guaranteed.
Turbos Reduce the Lifespan of an Engine
One of the most common turbo myths is that running boost will damage your engine over time. Again, it all comes down to design.
Unusual noises – a loud whining noise may be heard from your engine if your turbo has a fault. It will sound something similar to a dentist drill or a police siren – so if you hear this noise, it's definitely worth checking out, as this is a sign of turbo failure.
A smaller engine 1.0 lit petrol turbo can generate high torque of 178 nm torque (as in Kushaq) whereas some engines of 1.5 lit (Maruti s-cross) generate lower range 138 nm torque.
@ Mohan | 1.0 engine is better in terms of moderate power and best mileage than 1.2. In 1.2 more acceleration means more fuel loss and there is no remarkable increase in power especially in hills n steep hairpins while compared to 1litre. The 1l has spontaneous power in highways when crossing 60km/hr.
The good news is it is possible to add a turbocharger to just about any naturally aspirated (NASP) engine.
