de desempenho foram conduzidos conforme a norma “ABNT 1585 - Veículos rodoviários Código de ensaio de motores - Potência líquida efetiva”, e para os ensaios de emissões, foi utilizada como base, a Norma “ISO 8178 - Reciprocating internal combustion engines - Exhaust emission measurement”. Esta norma padroniza os procedimentos e ciclos de ensaio para motores estacionários, equipamentos industriais, motores marinhos e ferroviários, de utilidade doméstica, veículos off-road, e…

The demand for more powerful engines in smaller hood spaces has created a problem of insufficient rates of heat dissipation in automotive radiators. Upwards of 33% of the energy generated by the engine through combustion is lost in heat. Insufficient heat dissipation can result in the overheating of the engine, which leads to the breakdown of lubricating oil, metal weakening of engine parts, and significant wear between engine parts. To minimize the stress on the engine as a result of…

on reducing internal friction in combustion engines. The large number of vehicles in production in the current market and the release of the toxic gases produced by them, took the world market to adopt methods to reduce the release of harmful gases to the environment. Observed that reducing fuel consumption applied to internal combustion engines have significant impact in this direction. Among the many technologies applicable to internal combustion engines in recent years,…

codes, with the significant increase being in the structural area as stated earlier. The JASC code divides the engine section into two code groups to separate the turbine and reciprocating engines. The codes for the turbine engines are in JASC code Chapter 72, Turbine/Turboprop Engine. The codes for the reciprocating engines are now exclusively found in JASC code Chapter 85, Reciprocating Engine. The other major deviation from ATA Spec 100 is in ATA section 2730, specifically…

The system also produces unwanted heat and due to moving parts has internal friction which further reduces the system efficiency. A storage battery has an efficiency loss during the…

que melhor representa o funcionamento de um motor de combustão interna. O ciclo é composto por seis etapas representadas no diagrama P x V (STONE, 1999), conforme figura (3). Figura 3: Ciclo Otto teórico Fonte: Introduction to internal combustion engines, Richard Stone. Na etapa 0 – 1 ocorre admissão da mistura ar e combustível, ocorrendo compressão adiabática até o ponto 2. Do ponto 2 até o ponto 3, ocorre o rápido aquecimento da mistura a volume constante (processo…
