Who invented turbocharging?
Turbocharging has a whole history which started from when it was invented by Alfred Buchi, who had been working on steam turbines. Post that, this technology has been taken forward to amazing feats ranging from ships to aircraft.
Why are diesel engines turbocharged?
Diesel engines nowadays and turbocharging go hand in hand with each other. We can find turbocharged diesel engines in common automobiles such as trucks and locomotives for heavy machinery applications. Non-turbo charged diesel engines hardly exist in the market anymore and might become obsolete in the near future. Some of the reasons for which diesel engines are particularly suitable for turbocharging are: 1 The power to weight ratio in a naturally aspirated diesel engine is lower than gasoline engines. Turbocharging increases the power to weight ratio. 2 Diesel engines are already built-in with a robust fashion because they run at high compression ratios and high temperatures beforehand. Thus, they need only a little bit of modification to handle a turbocharger. Gasoline engines, on the other hand, need a lot more modification compared to diesel engines. 3 The engine speeds in diesel engines have a narrower band in which they operate making the operating characteristics of a turbocharger over the rev range a much better bargain than that of gasoline-powered engines. 4 During cylinder charging, diesel engines blow only air into the cylinders and squirt fuel only when the intake valve is closed and the compression has begun. In gasoline engines, both the fuel and air come simultaneously during the intake cycle and are both compressed during the compression cycle. Forced induction engines have higher intake charge temperatures, which reduces the compression possible in gasoline engines. Diesel engines are not sensitive to this.
What happens to fuel and air in a gasoline engine?
In gasoline engines, both the fuel and air come simultaneously during the intake cycle and are both compressed during the compression cycle. Forced induction engines have higher intake charge temperatures, which reduces the compression possible in gasoline engines. Diesel engines are not sensitive to this.
Why do turboshafts have ball bearings?
Some of the turbochargers use staggeringly precise ball bearings which are dunked in fluid dampened cavities. Because of very low friction, the turboshaft can be made with light materials which in turn reduces the boost lag or the turbo lag.
Why do turbines use fluid bearings?
Most of them use fluid bearings because it is impossible for standard ball bearings to bear the high rotational speeds generated by the turbine.
What is the purpose of a turbocharger?
The basic purpose of a turbocharger is to increase the vehicle’s horsepower by a notable amount but without adding excess weight to the whole car itself. We already know that the lighter the car, the faster it will move, and a turbocharger does just that. Its benefits have made it hugely popular over the years.
What happens to the temperature of air when compressed?
Hence when the air is then compressed and the pressure increases, the temperature does too.
How fast does a turbocharger spin?
The turbine in the turbocharger spins at speeds of up to 150,000 rotations per minute (rpm) -- that's about 30 times faster than most car engines can go. And since it is hooked up to the exhaust, the temperatures in the turbine are also very high.
How much more air does a turbocharger give?
The typical boost provided by a turbocharger is 6 to 8 pounds per square inch (psi). Since normal atmospheric pressure is 14.7 psi at sea level, you can see that you are getting about 50 percent more air into the engine. Therefore, you would expect to get 50 percent more power.
Why does a turbocharger have a wastegate?
If the pressure gets too high, it could be an indicator that the turbine is spinning too quickly, so the wastegate bypasses some of the exhaust around the turbine blades, allowing the blades to slow down. Some turbochargers use ball bearings instead of fluid bearings to support the turbine shaft.
What is a wastegate in a turbocharger?
Most automotive turbochargers have a wastegate, which allows the use of a smaller turbocharger to reduce lag while preventing it from spinning too quickly at high engine speeds. The wastegate is a valve that allows the exhaust to bypass the turbine blades. The wastegate senses the boost pressure.
How to reduce turbo lag?
One way to decrease turbo lag is to reduce the inertia of the rotating parts, mainly by reducing their weight. This allows the turbine and compressor to accelerate quickly, and start providing boost earlier. One sure way to reduce the inertia of the turbine and compressor is to make the turbocharger smaller.
Why are ceramic turbine blades lighter than steel?
Ceramic turbine blades are lighter than the steel blades used in most turbochargers. Again, this allows the turbine to spin up to speed faster, which reduces turbo lag.
Why do turbochargers need to run on higher octane fuel?
The temperature may increase enough to ignite the fuel before the spark plug fires. Cars with turbochargers often need to run on higher octane fuel to avoid knock. If the boost pressure is really high, the compression ratio of the engine may have to be reduced to avoid knocking. Advertisement.
How fast does a wind turbine turn?
Wind turbines begin turning when wind speeds are around 7 to 9 miles per hour and braking systems begin kicking in when wind speed is around 50-55 mph to prevent damage. At higher wind speeds the tips of the blades can get up to around 180 mph! The speed of the wind turbine depends on how fast the wind is blowing.
Why should wind turbine blades not spin too fast?
Wind turbine blades should not spin too slow or too fast but should be somewhere in the middle for the best results. If the blades are spinning too rapidly, they will create turbulence between them and will end up blocking the wind from entering through the gaps.
Why do wind turbines have brakes?
Faster wind speeds create more of a push causing the blades to spin more rapidly. The brake function is used within the nacelle to stop rotations if wind speeds are too fast and could cause damage to the machine’s hardware. There is a certain threshold of motion in which the wind turbines will operate. These limits are known as the cut-in speed and ...
What is the TSR on a wind turbine?
Another measurement that is performed on wind turbines is called the Tip Speed Ratio (TSR). This will help you find out how long it takes the blades to travel one circumference in a rotation time that is specified in seconds. It is important to know this number because it will help you monitor the efficiency of your wind turbine.
How to find RPM of wind turbine?
First, you can use a timer and manually count how many full rotations happen within that time frame. To make this easier, you can tie something to the end of one of the blades as a marker to help you keep track.
How many blades should a 4 blade turbine have?
This number gradually decreases when more blades are added to the turbine, so a 4-blade turbine should have a tip speed ratio of approximately 3, and a ratio of 2 can be expected for a turbine that has up to 6 blades.
What is the cut in speed?
The cut-in speed is the minimum wind speed to where the turbine can gain power from it and take its energy. Anything below this limit will not get a reaction from the turbine’s blades at all.
How does the speed of an alternator increase?
The speed of the alternator increases by burning more fuel and increasing the amount of hot steam .To do that more fuel should be injected to the boiler. Generally the speed of t. A generator is rotated by any kind of external force such as wind, water or steam.
How does a supratim generator work?
Supratim Biswas. A generator is rotated by any kind of external force such as wind, water or steam. The speed of the generator depends on the thrust provided by those external forces on the axis of the turbine blades. The electromagnetic torque acting over the blades helps to rotate the torque by certain speed.
