Abstract:

A utilização de combustíveis alternativos em MCI, visa a substituição ou a redução do consumo de combustíveis fósseis. Qualquer estudo do desenvolvimento de métodos e técnicas que melhore o desempenho dos motores usando combustíveis alternativos é de grande importância tecnológica, econômica e social. Com este fim, foi feito este trabalho de pesquisa, o qual consiste em ensaiar um motor usando misturas de 37% e 50% de etanol na gasolina. O etanol utilizado neste trabalho apresentou um grau alcoólico de 92 INPM aproximadamente. Os ensaios foram feitos em taxas de compressão 8:1, 9.5:1 e 11:1. F

As legislações com restrições nos níveis de emissões de poluentes e a grande concorrência entre as montadoras fomentaram o desenvolvimento de sistemas mais eficientes de gerenciamento de motores a combustão interna. Entretanto, a falta de sensores que identifiquem as propriedades da combustão, e que sejam economicamente viáveis, dificulta o desenvolvimento de novos sistemas. Visando suprir parte dessas limitações, este trabalho propõe o uso do sensor de corrente iônica com duas finalidades: identificação dos fenômenos de combustão e detonação.

Face aux normes actuelles et futures, de plus en plus drastiques, concernant les émissions de polluants, les constructeurs automobiles cherchent en permanence à améliorer l'efficacité des moteurs à allumage commandé. Une des solutions les plus efficaces et applicables pour diminuer la quantité de polluants émis dans les gaz d’échappement (HC, CO, NOx) et réduire la consommation de carburant, est d’utiliser un mélange très pauvre (richesse du mélange inférieure à 0,6). Toutefois, ce concept de fonctionnement est limité par les systèmes d'allumage classiques qui ne peuvent pas garantir un alluma

Abstract:

Lately, car manufacturers have been put to a big challenge to reduce the CO2 emission of their entire fleets. Norms of pollutant emissions limit the ways to achieve the desired CO2 emission goals, as some of the solutions that would lead to lower CO2 emission also lead to higher pollutant emission. Waste Heat Recovery (WHR) could be a good solution to lower the CO2 emission of the Internal Combustion Engine (ICE) without increasing the pollutant emission. In the present thesis different WHR strategies are analysed and the results suggested it would be interesting to further study the Brayton c

Abstract:

Controlled Auto Ignition (CAI) combustion is a new combustion principle in internal combustion engines which has in recent years attracted increased attention. In CAI combustion, which combines features of spark ignition (SI) and compression ignition (CI) principles, air/fuel mixture is premixed, as in SI combustion and auto-ignited by piston compression as in CI combustion. Ignition is provided in multiple points, and thus the charge gives a simultaneous energy release. This results in uniform and simultaneous auto-ignition and chemical reaction throughout the whole charge without flame propa

Laser ignition is one of the latest attempts to improve the efficiency and performance of an IC engine. It is slightly unique in that the ignition source is one of the few component of a spark ignited engine that has not been changed in a long time. It is a system that allows a lot of freedom in what can be done with it. Common freedoms are the spatial placement of the spot, splitting the laser into multiple spots, and firing multiple lasers into the engine during a single cycle. It is the last that this thesis is mostly concerned with. Temporal variations are uniquely allowed by lasers over s
