A SI Engine Indicated Characteristics Determination for Gasoline and Methane Operation

Impact of Methanol–Gasoline Fuel Blends on the Performance and Exhaust Emissions of a SI Engine

Effect of Ignition Timing, Equivalence Ratio, and Compression Ratio on the Performance and Emission Characteristics of a Variable Compression Ratio Si Engine using Ethanol-Unleaded Gasoline Blends

This paper investigates the effect of ethanol-unleaded gasoline blends (E0,E10,E25,E35,andE65) computer interfaced, four-stroke single cylinder compression ignition engine. The said engine wasconverted to spark ignition and carburetion to suit ethanol fuel. A suitable provision was provided on theengine to vary the compression ratio thereby making the engine adaptable to operate at lowercompres...

Modeling and Programming for a Computer Controlled Direct Gasoline Fuel Injection System of SI Engine

A computer controlled direct gasoline fuel injection (DGI) system has been modeled, programmed and constructed for a four-stroke SI engine. Locally available materials have been used for this experimental model. All the old model vehicle were equipped with carburetor for air fuel mixing and later on electronic fuel injection system has been introduced for maintaining better air fuel ratio and m...

Model-based Feedback Control for an Automated Transfer out of Si Operation during Si to Hcci Transitions in Gasoline Engines

This paper takes a first step towards model-based feedback control for the transition between spark ignition (SI) and homogeneous charge compression ignition (HCCI) combustion modes by approaching the transfer out of SI operation during the SI into HCCI transition in a closed-loop control framework. The combustion mode switch is taken to be directly from SI to HCCI without an intermediate combu...
