Abstract:
An experimental investigation was performed to study the effects of engine operating parameters, such as, intake valve temperature, intake valve lift, injection pressure, air flow rate and fuel injection duration, on the vapor concentration field in the combustion chamber of SI engine with the multipoint fuel injection. The vapor concentration in a model transparent combustion chamber during intake stroke of an engine was determined by the intermittent injection of gasoline, Freon-113 into the steady flow of dust-free dry air through an intake port with the application of laser Rayleigh Scattering. The results showed that the vapor concentration field was strongly affected by the engine operating parameters. It was also found that the present optical system was effective for the time and space resolved measurements of vapor concentration in the combustion chamber in the case of liquid fuel injections.
