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. Sound: Turbos muffle engine sounds, making cars with turbo engines quieter to drive.
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.
For those looking to balance performance with fuel economy and efficiency, turbocharging is the better choice. For those more interested in a straightforward solution to raw horsepower, supercharging is more likely the way to go.
Pro: You get more efficiency with turbo engines, saving money in fuel costs. Con: Turbo lag can occur when you try to accelerate quickly, a slight delay in the delivery of power due to the turbine taking time to spin up. Pro: A turbo engine produces higher torque numbers in the lower rev range for faster acceleration.
Does it require special maintenance or care of any kind? 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.
Warm up your engine
This puts extra pressure on the oil seals. As the engine temperature increases, so does oil temperature. This thins the oil, enabling it to run more freely and lubricate the moving parts of your engine.
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.
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.
“Generally speaking, turbocharging is a great idea. It's a smaller engine, but you're still getting a decent amount of power,” says Mike Quincy, autos editor at Consumer Reports. “The idea with a smaller engine, especially a four-cylinder, is that you're going to get decent fuel economy without giving up power.
Turbocharged engines will require more frequent oil changes and fresh spark plugs, though turbo engines typically don't require additional service compared to naturally aspirated 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.
A turbocharger won't improve an engine's fuel economy, but it will get more horsepower out of a smaller, more fuel-efficient engine. When comparing turbocharger vs. supercharger, you're more likely to find a fuel efficient vehicle powered by a turbocharger than a supercharger.
For all turbo petrol engines 95 octane petrol is recommended.
Drive your car gently for the last minute or two of the drive, or let the car idle afterwards for at least 60 seconds. By letting it run. the oil will continue to circulate and cool down the turbo. One of the main reasons your turbo will die is because of oil “coking”.
Turbochargers are poorly lubricated and cooled. Idle mode for just 20 minutes is sufficient to be harmful to a turbocharger, not only when running-in, but also in the course of normal operation.
Turbocharged engines do need to cool down before they are turned off. But in nearly all driving conditions, the engine does not reach temperatures that require a deliberate cooling down period.
Let the car idle for 30 (minimum) - 60 (maximum) seconds before you drive off. Use this handful of seconds to set the right playlist, climate control, mirrors and seat position. Be gentle to your car when she's cold. Maintain a low rpm level (below 2,000) until the engine has reached operating temperature.
As air temperature increases the density of the air, and the amount of oxygen it holds, decreases. This means that the turbocharger has to work harder, spin faster and compress more air to produce the same amount of boost it would at lower temperatures.
Turbocharged cars are more likely to break down and are more expensive to repair, according to data from the UK's leading car warranty supplier, Warranty Direct. It found the average incidence rate of turbo failure to be 27.8 per cent – around 2.5 times that of engine failure overall at 11.3 per cent.
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.
The average cost for a Turbocharger Assembly Replacement is between $1,949 and $2,251. Labor costs are estimated between $497 and $627 while parts are priced between $1,452 and $1,624.
With proper maintenance and good driving habits, a turbocharged engine shouldn't have any significant reliability concerns compared to a naturally aspirated engine.
