To most people, turbo kits invoke images of loud and very fast sports cars. They often think that the unit only kicks in, or is necessary, when you want to go faster. While this is the primary function, there are other advantages associated with turbo kits. The following article offers insight on the intricacies of a turbo kit.
The turbo kit works on the forced air induction principle. The unit forces more air into the cylinders, thereby ensuring more power is produced. There is an attached turbine in the exhaust manifold. The force of the escaping gases turns the turbine, which is in turn connected to a compressor. The pump delivers more air into the inlet manifold. This ensures a continuous supply of a rich air fuel mixture to the cylinders, which means more power output.
The turbo kit is attached to the exhaust manifold. The attached turbine is turned by the escaping exhaust gases. Via an attached shaft, the turbine operates an air pump, or compressor, which adds on pressure to the incoming air in the inlet manifold. Other additional components include;
Waste gate: the escaping exhaust gases can spin the turbine at speeds of up to 150,000rpm. Such high speeds can result to wear and overheating. An installed waste gate allows some exhaust gases to escape before they get to the exhaust.
Bearings: The turbo kit uses special ball bearings and fluid bearings. The special material ball bearings are resistant to wear and high temperatures associated with such speeds. Fluid bearings on the other hand suspend the shaft in a layer of constantly pumped fluid. This serves the dual purpose of lubrication as well as cooling.
Power output: there are various ways to increase the power output of an engine. You can add on extra cylinders, or increase the size of the cylinders. In most scenarios, such measures are not possible. A more practical way to increase power is to install a turbo kit.
Fuel consumption: if you compare a turbo- charged engine with a regular engine, in-lieu of the power produced, you will find that the former uses less fuel. This is because the turbo equipped engines tend to be smaller when compared with the power produced. It will usually have fewer cylinders, thus making for better fuel economy.
Pollution: the turbo kits, by reutilizing the exhaust additionally act as silencers. This means that they will produce less noise than a naturally aspirated engine with the same power output. In the same vein, turbo kits take advantage of the exhaust gases to create pressure for more air intake. They also make for smaller and more compact engines with less emission.
Performance: in the high altitude areas, engines generally produce less power, due to the lower pressure associated with such areas. Turbo kits primarily direct more air to the engine. In such low pressure areas, the performance actually improves due to the high engine-atmosphere pressure difference. In this regard, regardless of the area, you can be assured of prime engine performance.
Engine weight: lighter cars tend to be more efficient. Turbo kits are designed to increase the power output of an engine. This means a reduction in the number of cylinders required. To increase power in a regular engine, you will require increasing the size and weight, which in turns uses up more fuel.
