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.
What is the disadvantage of turbo engine?
Smaller engines use less fuel, but being turbocharged adds pressure, which can lead to higher temps and engine knock, damaging the engine. To avoid this, you have to have a lower compression ratio. Thermal efficiency and compression ratio are directly correlated.
What is the advantage and disadvantage of turbo engine?
When an engine is fitted with a turbocharger, it is theoretically smaller and lighter than an engine producing the same power without a turbocharger. So, a turbocharger car often gives better fuel economy in that respect. Car manufacturers often use a much smaller engine to the same car.
Do turbos decrease engine life?
2. Turbos Reduce the Lifespan of an Engine. One of the most common turbo myths is that running boost will damage your engine over time. … However, a properly implemented turbo pushing enough PSI through a motor to produce respectable levels of power won’t strain a motor any more than idling in traffic will.
Does turbo use more fuel?
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.
How many miles do Turbos last?
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.
Is a 4 cylinder turbo faster than a V6?
Modern turbocharged four-cylinder engines, when engineered properly, will either beat or match a naturally aspirated V6 in almost every category. Turbo-fours are lighter, more efficient, and can be more powerful than a naturally aspirated V6. The only thing that a V6 will always do better is towing capacity.
At what speed does turbo kick in?
The boost is achieved by using the exhaust flow from the engine to spin a turbine and then spinning an air pump. The turbine in the turbocharger can spin at speeds of up to 150,000rpm, which is 30 times faster than most car engines can go.
How often should you change oil in a turbo engine?
For the best performance from a turbocharger, change the oil at least every 5,000 miles, replacing it with a fully-synthetic oil which is the right API for your car’s engine type. Your vehicle’s handbook should recommend the best choice of oil for your car.
