Engine performance depends on two main factors of engine speed and ignition time. Ignition timing can affect engine life, fuel economy and engine power. In this paper, to study engine performance of Peugeot 206 TU3A with comparison ratio of 10.5:1 and displacement of 1361CC in MATLAB software, a two-zone burned/unburned model with the fuel burning rate described by aWiebe function was used for ...

the purpose of this study is to investigate the effect of injection parameters on a heavy duty diesel engine performance and emission characteristics. in order to analyze the injection and spray characteristics of diesel fuel with employing high-pressure common-rail injection system, the injection characteristics such as injection delay, injection duration, injection rate, number of nozzle hole...

This study deals with artificial neural network (ANN) modeling a diesel engine using waste cooking biodiesel fuel to predict the brake power, torque, specific fuel consumption and exhaust emissions of engine. To acquire data for training and testing the proposed ANN, two cylinders, four-stroke diesel engine was fuelled with waste vegetable cooking biodiesel and diesel fuel blends and operated a...

Next level of passenger vehicles engines evolution is needed to comply with fuel economy and pollutant regulation legislative requirements. Turning a combustion engine with modern control systems into reverse uniflow two-stroke engines improves the power density of the engine and minimizes negative aspects of using the classic two-stroke engines. Variable valve timing allows control of the inta...

At the previous conference KONES’2004 emission characteristics of C.I. engine fuelled with either rape oil methyl ester (RME) or diesel fuel (DF) as a main fuel and ethanol as additional fuel were presented. Comparison of emission and brake fuel conversion efficiency (BFCF) of the engine fuelled with both main fuels showed that fuelling with RME and ethanol is more advantageous on account of bo...

The Electronic Return-less Fuel System (ERFS) manages the delivery of fuel from the fuel tank to the engine. The pressure in the fuel line is electronically controlled by the fuel system control module by speeding up or slowing down the fuel pump. This allows the system to efficiently control the amount of fuel provided to the engine when compared to vehicles equipped with a standard fuel syste...

This paper describes a cost-effective fuzzy control system applied to a small spark-ignition internal-combustion engine to achieve regulation of the fuel injection system. It determines the amount of fuel required from a fuzzy algorithm using engine speed and manifold air pressure as input values. The fuzzy control parameters were a collection of comprehensible rules and fuzzy-set membership fu...

The main objective of this paper to discuss the research output for getting better engine performance with lower noxious emissions by improving the fuel quality. The control of diesel fuel properties as a means of Regulated pollutants continues to be charged with reaching various air quality goals. Some additives play effective role in diesel fuel for improving fuel‟s quality and minimize the p...

An understanding of aircraft fuel burn and emissions is necessary to evaluate their effects on the environment. In this paper, data from Flight Data Recorders (FDRs) have been used to estimate the operational values of times in mode, fuel flow rates, fuel burn, NOx emission indices, and quantities of emissions produced during the Landing and Take Off (LTO) cycle for 12 aircraft-and-engine combi...
