Auto turbines. Features, innovations and malfunction ceasing

Automotive designers (since the appearance of this profession) are constantly concerned with the problem of increasing the power of motors. The laws of physics state that engine power directly depends on the amount of fuel burned in one working cycle. The more fuel we burn, the more power we get. The turbine efficiency is highly dependent on engine speed. When you are driving the best cars, rented at the luxury car rental baltimore md, you literally feel the power of the car’s engine.

Car turbine features

The most effective device for increasing the power of a car engine is a turbine. However, it has a number of significant drawbacks, such as the presence of a turbo lag, optimal operation in a small range of engine speeds, a low resource and the complexity of installation in an engine that is not prepared for this.

Many of these problems can be solved by an electric turbine. With an electric turbine, the required boost pressure can be created at any time and you can slow down without fear that the pressure will drop. In an electric turbine there is no hot part heated to a thousand degrees. This has a positive effect on its resource, price and ease of installation.

For each engine, the turbocharger is selected individually, based on its own power and volume. Moreover, the amount of pressurization depends on the geometric parameters of the scrolls, compressor wheel, and a turbine rotor. Some engine designs are equipped with not one turbine, but two: the same size – bi-turbo, different sizes – twin-turbo. Recently, variable geometry turbochargers have become widespread.

Advantages of an electric turbine

After analyzing the modern car market, it was claimed in some sources that by 2021 the share of cars that will be equipped with electric turbines would account for 50-60% of the total number of vehicles coming off the assembly line. Moreover, an economical device that helps to respond faster to changes in the accelerator pedal will be developed. This turbo system is beneficial only in a certain range of engine rpm that is why in an engine with a conventional turbocharging system it is hard to meet such requirements.

The main advantage of electric turbines is in efficient air injection throughout the car’s entire engine speed range. It is possible even at the moment the engine is started, because the forced air is already in the intake manifold. Even pumping air while shifting the gear, you will continuously receive additional energy in order to move and accelerate.

Visteon Torque Enhancement System 

This system has been developed by Visteon, a reputed manufacturer of automotive components. As the developers note, their brainchild will become a worthy replacement for turbochargers and mechanical compressors, which have been used for several decades to increase the power of internal combustion engines. 

The advantages of the new development is that it is devoid of the disadvantages inherent in turbochargers and compressors. Electric supercharging does not take away power from the motor, reacts without deceleration to pressing the gas pedal, and during the acceleration, it excludes even the slightest dips in the engine operation. For example, electrically aspirating a car with a 1.2-liter engine in fifth gear accelerates 40% faster than a naturally aspirated car. This allows such small cars to compete successfully with cars equipped with 1.8-liter atmospheric power units. The improved mixture formation, which is provided by a higher airflow rate, also made it possible to increase the engine efficiency by 20%. The VTES system consists of two main elements – an electric compressor with auxiliary units (filter and valves) and an electronic control unit. Such a kit is compact and light (weighs only 5 kg), which allows it to be implemented in almost any car.

What if your turbine vacuum actuator is not working? 

Increasing the performance of a car and making tuning by installing a turbine is a frequent activity. A turbine with an actuator is very popular among professional and car enthusiasts, in view of the constant operation of the engine at high speeds, for the protection of which the actuator was invented. It should be understood that an actuator is not an obligatory technical unit of a turbine and an engine. Do not be surprised if you do not know this name, as it is also called the wastegate or vacuum regulator. It releases exhaust gases outside the turbine wheel, and thus combats overload.

Without proper functioning and proper adjustment of the actuator:

  • The turbocharger operates at increased speed for wear, which affects the duration of its operation in general.
  • Engine operation will be impaired.
  • A specific rattling sound will be heard when the motor is turned off.
  • The boost will be weak.

When installing a turbine with an actuator on its own, special vehicle control devices are required. If mistakes are made, the turbine can fail along with the engine.

Reasons for failure of the actuator

  1. Breakdown of electronic components responsible for the operation of the valve (electric motor).
  2. Component parts of the actuator become unusable (spring is loose).
  3. Tightness deterioration.
  4. High mileage of a vehicle with a turbocharger.
  5. Service life has ended.

If one of these reasons occurs, or several at once, they signal the car enthusiast that it is needed to visit the car service.

The design of turbo engines has been brought up to date long time ago, but only recently, their popularity has increased dramatically. Moreover, turbochargers turned out to be promising not only in terms of forcing engines, but also in terms of increasing the efficiency and purity of the exhaust. This is especially true for diesel engines. The installation of a turbine on gasoline engines allows to turn an ordinary-looking car into a worthwhile item.
