Performances of a Spark Ignition (SI) engine fuelled with Liquefied Petroleum Gas (LPG) using Liquid Sequential Injection (LSI) technique
… interest on alternative fuels particularly in spark ignition (SI) engines. One of the seen potential of alternative fuel is Liquefied Petroleum Gas (LPG). LPG has a research octane number higher than gasoline and low carbon to hydrogen ratio content, thus the LPG has the potential to give more …

A CFD study of fuel evaporation and related thermofluid dynamics in the inlet manifold, port and cylinder of the CFR octane engine
Spark Ignition (SI) engine fuels' anti-knock properties are measured in the Co-operative Fuel Research (CFR) engine under two different test conditions as prescribed by the American Society for Testing and Materials (ASTM) for Research Octane Number (RON) and Motor Octane Number (MON) ratings. …

Exergy Based SI Engine Model Optimisation. Exergy Based Simulation and Modelling of Bi-fuel SI Engine for Optimisation of Equivalence Ratio and Ignition Time Using Artificial Neural Network (ANN) Emulation and Particle Swarm Optimisation (PSO).
In this thesis, exergy based SI engine model optimisation (EBSIEMO) is studied and evaluated. A four-stroke bi-fuel spark ignition (SI) engine is modelled for optimisation of engine performance based upon exergy analysis. An artificial neural network (ANN) is used as an emulator to speed up the …

Combustion lean limits fundamentals and their application to a SI hydrogen-enhanced engine concept
Operating an engine with excess air, under lean conditions, has significant benefits in terms of increased engine efficiency and reduced emissions. However, under high dilution levels, a lean limit is reached where combustion becomes unstable, significantly deteriorating drivability and engine …

Fuel effects in homogeneous charge compression ignition (HCCI) engines
Homogenous-charge, compression-ignition (HCCI) combustion is a new method of burning fuel in internal combustion (IC) engines. In an HCCI engine, the fuel and air are premixed prior to combustion, like in a spark-ignition (SI) engine. However, rather than using a spark to initiate combustion, the …

Effect of fuel properties on the first cycle fuel delivery in a Port Fuel Injected Spark Ignition Engine
… while also yielding low hydrocarbon (HC) emissions is difficult for the first cycle of cranking during the cold start of a Port Fuel Injected (PFI) Spark Ignition (SI) engine. Cold intake port wall and valve temperatures, near-atmospheric manifold pressure, and low port air velocity combine to …

A study on the emissions of butanol using a spark ignition engine and their reduction using electrostatically assisted injection
… diesel fuel. Additionally, butanol is less corrosive and less prone to water absorption than ethanol, which allows it to be transported using the existing fuel supply pipelines. However, while some previous research on the emissions of butanol-gasoline blends is available, little research exists …

Development of a High Speed Data Acquisition System for Spark Ignition Engine
Full engine control can only be accomplished with multi-input multi-output (MIMO) control system requiring measurement of variables for which no sensor/instrument is yet available in the Renewable Energy and Engines Laboratory, therefore a less detailed single input single output (SISO) engine …
