Auto-ignition of direct injection spray of light naphtha, primary reference fuels, gasoline and gasoline surrogate

A Study of Fuel Impingement Analysis on In- Cylinder Surfaces in a Direct-Injection Spark- Ignition Engine with Gasoline and Ethanol-Gasoline Blended Fuels

An experimental study is performed to investigate the fuel impingement on cylinder walls and piston top inside a directinjection spark-ignition engine with optical access to the cylinder. Three different fuels, namely, E85, E50 and gasoline are used in this work. E85 represents a blend of 85 percent ethanol and 15 percent gasoline by volume. Experiments are performed at different load condition...

Modelling of Gasoline Spray Impingement

This paper is concerned with aspects of gasoline spray droplet impingement simulation, for which an improved model has been developed for predicting the outcomes of spray droplets impacting on a wall. The model is assessed by simulating experiments on oblique spray impingement in a wind tunnel. This is done with the aid of a specially-devised procedure for deducing the specification of initial ...

Characterisation of Particulate Matter Emitted from Aviation Gas Turbines and Spray-Guided Direct Injection Gasoline Engines

Performance and Emission Characteristics of Spark Ignition Engine Fuelled with Ethanol and Methanol Gasoline Blended Fuels

Depletion of fossil fuels and environmental pollution has led researchers to anticipate the need to develop bio-fuels. Alcohols are an important category of bio-fuels. Methanol can be produced from coal, biomass or even natural gas with acceptable energy cost. Also, gasification of biomass can lead to methanol, mixed alcohols, and Fischer–Tropsch liquids (Chum and Overend, 2001). Ethanol is pro...

Object Oriented Modeling of a Gasoline Direct Injection System

The topic of this paper is the object oriented modeling of a Common Rail Direct Injection System of a gasoline engine. The injection system of a gasoline engine is described; the main functional elements are detailed and an object oriented implementation using the Modelica language is proposed. The availability of a fast and easily reconfigurable simulator allows to study how different parts of...
