The turbocharger has unleashed a new era of highly efficient internal combustion engines and shows the right technology to meet global emissions laws. With a simple concept, the turbocharger can reduce the specific fuel consumption, increase engine power and torque by increasing its volumetric efficiency. By using the energy contained in the exhaust gases, the turbocharger compresses the atmospheric air, increasing its density, so that at the moment of combustion there is a more efficient burning of the fuel injected. The purpose of this paper is to analyze the internal components of the turbocharger and a computer simulation made in Ricardo Software's Waves to analyze differences in fuel consumption, volumetric efficiency, torque and in the power of a turbocharged engine compared to the same engine, but without the turbocharger installed.

Several injection and ignition systems have been developed and tested since the invention of the internal combustion engine. As environmental regulations have become more stringent over the years, an electronic injection and ignition systems of the mixture air/fuel was implemented in the vehicles. Since then these systems have constantly been improved with the inclusion of devices, sensors and actuators that help them work more efficiently, both to gain power and for the enforcement of environmental laws in force in each country. For the correct operation of the engine electronic management it is extremely important to develop a software that can perfectly control the inputs (sensors) and outputs (actuators) information. The task of adjustment and calibration of the software requires a programmable module, which is connected to the vehicle and tested with various settings until an ideal fit between performance and emissions can be reached.

Since the technology applied to vehicles is constant increasing, new systems are being developed to improve performance, comfort and safety. The main way to improve safety is to keep the driver informed about unsafe traffic. In this paper we propose the development of an algorithm that works with an Antilock Brake System, in order to keep the driver informed about the distance between the vehicle equipped with this system and another one in front of it, by this way there is more time to make a safe breaking. The interaction between the driver and this method is given by a visual alert system.
