Air-to-Fuel and Dual-Fuel Ratio Control of an Internal Combustion Engine
Air-to-fuel (A/F) ratio is the mass ratio of the air-to-fuel mixture trapped inside a cylinder before combustion begins, and it affects engine emissions, fuel economy, and other performances. Using an A/F ratio and dualfuel ratio control oriented engine model, a multi-inputmulti-output (MIMO) sliding mode control scheme is used to simultaneously control the mass flow rate of both port fuel inje...
متن کاملSliding Mode Control of Both Air-to-Fuel and Fuel Ratios for a Dual-Fuel Internal Combustion Engine
A multi-input-multi-output (MIMO) sliding mode control scheme was developed with guaranteed stability to simultaneously control air-to-fuel ratio (AFR) and fuel ratios to desired levels under various air flow disturbances by regulating the mass flow rates of engine port-fuel-injection (PFI) and direct injection (DI) systems. The sliding mode control performance was compared with a baseline mult...
متن کاملFuzzy Air-Fuel Ratio Control of a Small Gasoline Engine
This paper describes an investigation in which a fuzzy control paradigm was applied to a small spark-ignition gasoline-fuelled internal-combustion engine, to achieve regulation of the fuel injection system. The control system determined the amount of fuel required from a fuzzy algorithm that used the engine speed and manifold air pressure as input values. The parameters of the fuzzy system cons...
متن کاملDesign and Simulation of Air-Fuel Ratio Control System for Distributorless CNG Engine
This paper puts forward one kind of air-fuel ratio control method with PI controller. With the help of MATLAB/SIMULINK software, the mathematical model of air-fuel ratio control system for distributorless CNG engine is constructed. The objective is to maintain cylinder-to-cylinder air-fuel ratio at a prescribed set point, determined primarily by the state of the ThreeWay-Catalyst (TWC), so that...
متن کاملAir-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...
