Experimental Investigation of The Performance Response of A Spark Ignition Engine to Adding Natural Gas to Gasoline in Lean-Burn Condition

Considering the disadvantages of gasoline and natural gas as mono-fuel in SI engines has made the researchers to improve the performance and reduce the pollutant as the advantages of the application of dual fuel engines. On the other hand, lean-burn in engine may lead to the reduced pollutant. In the present study various mixtures of gasoline and natural gas with the gasoline as the dominant fu...

Flame Front Propagation in an Optical GDI Engine under Stoichiometric and Lean Burn Conditions

Lean fueling of spark ignited (SI) engines is a valid method for increasing efficiency and reducing nitric oxide (NOx) emissions. Gasoline direct injection (GDI) allows better fuel economy with respect to the port-fuel injection configuration, through greater flexibility to load changes, reduced tendency to abnormal combustion, and reduction of pumping and heat losses. During homogenous charge ...

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...

Knock Behavior of a Lean - Burn , Hydrogen - Enhanced Engine Concept

Experiments to identify the knock trends of lean gasoline-air mixtures, and such mixtures enhanced with hydrogen (H2) and carbon monoxide (CO), were performed on a single-cylinder research engine with boosting capability. The experimental method used to investigate knock trends consisted of determining the octane number (ON) of the primary reference fuel (mixture of isooctane and n-heptane) sup...
