Combustion Engine

turbine without inlet air cooling (base line), gas turbine with evaporative cooling, gas turbine with absorption cooling system that uses steam generated in a heat recovery boiler and gas turbine with absorption cooling directly driven by hot combustion engine gas. For each of the configurations it was developed a cost and financial evaluation considering two scenarios. The first one considers a gas turbine installation without extra capacity for electricity demand increase. In the…

instance, the Quioto Protocol and the effort of both manufacturers and governments to develop and apply alternative fuels and new propulsion technologies. This is where hybrid technology appears, combining an internal combustion engine with one or more electric engines, along with an engine management and an energy recovering system; this technology presents a new type of propulsion with the aim of reducing energy consumption. However, due to the lack of information about this new…

Within this context, take a byproduct from the process of sewage treatment, biogas fits perfectly on current needs. Biogas is a highly energetic fuel, composed primarily of methane, which can be used for power generation, given from the internal combustion engine by the use in turbines. The biogas is produced by anaerobic digestion by the action of a group of bacteria that degrade the organic matter in the medium in the absence of oxygen. This study aims to evaluate the production of…

process drives the electric motor that positions the throttle, so the ECU has full autonomy to get the best performance of the vehicle, either in route or cold start. Most of the accelerator pedal systems used in electron injection internal combustion engines (when there is the existence of cable) available today is based on resistive sensors (potentiometers). These pedals use technology knoed and cheaper, but this technology has some problems with respect to wear and resistance…

BIODIESEL THROUGH LIQUID CHROMATOGRAPHIC SEPARATION OF ITS CONSTITUENTS Débora França de Andrade Agosto, 2011 Supervisors: Prof. Luiz Antonio d’Avila, Dr. Prof. José Luiz Mazzei da Costa, Dr. The contaminants on biodiesel can lead to problems in combustion engines. Mono, di and triacylglycerols (MAG, DAG and TAG), stand out as contaminants of pure biodiesel (B100), which are produced from the transesterification of vegetable oils. These components originate from partial conversion to…
