The characteristics of an alcohol+gasous fuel S.I. engine.

Study of Combustion Characteristics of an SI Engine Fuelled with Ethanol and Oxygenated Fuel Additives

This study investigates the effects of ethanol-blended gasoline with oxygenated additives on a multi – cylinder Spark Ignition (SI) Engine. The experiments were conducted in two stages. In stage I, the test fuels were prepared using 99.9% pure ethanol and gasoline with a cycloheptanol blend, in the ratio of E69.5 + 0.5 cycloheptanol, E64.6 + 0.4 cycloheptanol, E59.7 + 0.3 cycloheptanol, E49.8 +...

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

effect of bioethanol-gasoline fuel blends on an si engine exhaust emissions

in this paper, the effect of bioethanol- gasoline fuel blends on exhaust emissions of a four-cylinder spark ignition (si) engine was investigated experimentally. pure gasoline fuel was blended with various percentages of bioethanol (0, 20, 40, 60 and 85%), and the hc, co, co2 and nox exhaust emissions were measured at different engine speeds and two throttle valve positions (full throttle and 5...

Characteristics of fish oil biodiesel with the impact of diesel fuel addition on a CI engine

The present study focuses on the optimization in the use of non-petroleum fuel derived from waste fish oil fuels, as a replacement for petroleum diesel fuel for compression ignition engine. The study comprises of comparison between results of fish oil biodiesel-diesel blends on a compression ignition engine. Fuel properties such as viscosity, density, heat value of fuel, cetane number and a fla...

Air-Fuel Ratio Control of a Lean Burn SI Engine Using Fuzzy Self Tuning Method

Reducing the exhaust emissions of an spark ignition engine by means of engine modifications requires consideration of the effects of these modifications on the variations of crankshaft torque and the engine roughness respectively. Only if the roughness does not exceed a certain level the vehicle do not begin to surge. This paper presents a method for controlling the air-fuel ratio for a lean bu...
