At a certain point that pressure has to be nipped in the bud and that’s when the control system does its stuff. Mechanical wastegate actuators are opened by pressure from the boost side of the turbo acting on a diaphragm inside the actuator. That opens a simple valve on the hot side allowing exhaust gas to bypass the turbine. At the same time, inlet boost pressure must be released and that’s what the cold side pressure relief valve does. Left: A Garrett turbocharger. Right: A T-piece sending pressure to a boost gauge. The question could arise that why not the turbochargers get overheated despite running in extreme temperatures and taking huge loads of pressure. The answer is – an intercooler. There is an intercooler with every turbocharger that cools down the discharged hot air. The oil cooling system takes care of the turbo and does not let it become overheated. Hopefully this article will be useful for you. If you have any car question, feel free to leave us a comment in the box below, we will answer it for you. There’s one particular reason for this and that’s balance. The Garrett T3 fitted to cars like my Ford Sierra Cosworth will reach 110,000rpm and the only thing between its compressor and the engine is the intercooler. Catastrophic turbo failures resulting in fragments being swallowed by the engine don’t bear thinking about and a specialist will balance the assembly and rebuild the turbo to factory specifications. In the UK, Owen Developments is a well known purveyor of all things turbo and there’s also Bernie Wilky of Bernie’s Blowers fame who can be found on Facebook.

The turbocharger is a familiar term when you talk about race cars and high-performance sports vehicles. They are also not uncommon to find in larger diesel engines. A turbo is a device that can enhance the horsepower of an engine without adding to its weight. How does a turbo work and make that possible? And, what features have made them so popular? What Is a Turbocharger?The turbine rotates at a high speed and spins the compressor too as both are mounted on the same shaft.

The exhaust gasses leave the car through the exhaust pipe. They waste less energy than an engine not having a turbocharger. The hot air cools down when passing through the heat exchanger and enters the cylinder’s air intake. Also called VTS, this turbocharger combines variable geometry turbo with twin-scroll turbo. With this special combination, the variable twin-scroll turbocharger provides a more robust alternative, as well as cheaper for car owners. Electric Turbochargers

People from the 1980s are likely to be better acquainted with the word ‘turbo’ because it was applied to plenty of products at that time such as turbo skateboards, turbo razors, and many other things. But, this is not what has revolutionized the auto industry. The extra power is definitely the key selling point of turbochargers but it is not the only benefit they offer. Another lucrative advantage is the fuel efficiency. A turbo engine uses much less fuel to produce the same power as compared to the standard engines. This is the reason for Ford to use a 1.0-liter turbo engine in the place of the 1.6-liter petrol engine in some of their models. Similarly, you will see a 4-cylinder turbo engine instead of a 6-cylinder and a turbocharged V6 replacing a V8 in many new models. A generic description of what happens is this. As engine load increases and the engine produces more power, the exhaust pressure increases at the same time. Since it passes through the hot side of the turbocharger, the turbine is driven faster, driving the compressor wheel on the cold side at the same revs, and that pressurises the intake system. The air gets hot when it’s compressed which isn’t good for combustion so it usually passes through an intercooler on the way to the engine’s inlet ports via a throttle body, or individual throttle bodies. Intercoolers are simply air-to-air heat exchangers, like a radiator but without the water.

If it seems a bit complicated to understand how a turbo works, take the cue from the fact that an engine run by a mixture of fuel and air. When a turbocharger brings more air into the chamber, it gets mixed with more fuel, yielding more power as a result. It smuggles air by compressing it using the energy of the exhaust gasses coming out of the engine. A turbo engine. Source: Fast Car Different Types of Turbocharger? Almost all the modern cars with diesel-run engines have turbochargers because diesel engines are tougher than petrol units and have simpler intakes. How Does a Turbocharger Work? (At a Glance)Another benefit of using turbochargers is that they enable the engine to yield more torque at the lower rev range, which gives a car an edge while driving around the city. The additional torque comes handy for easily pinching the gaps. When the hot air leaves the engine, it winds a turbine that in turn drives an air pump or compressor located at the engine’s front side. It pushes the air into the engine and allows a proper burn of the fuel. Alfred J. Büchi (1879-1959) is the father of this incredible car part. He is an automotive engineer employed by the Gebrüder Sulzer Engine Company of Winterthur, Switzerland. Alfred created the turbocharger before World War I and published it in Germany in 1905. His contribution to the turbocharger is so great he kept improving designs for it until his death. What is the disadvantage of turbo engines? Turbocharged cars are actually better than standard petrol vehicles because they use less fuel and burn oil more cleanly to cause less air pollution.
