PROBLEM TO BE SOLVED: To suppress deterioration of exhaust emission due to a response delay, by quickening response of air/fuel ratio control when an opening of an EGR (exhaust gas recirculation) valve or an intake throttle valve is large.GOTO ISAMU...
Air-fuel ratio control device for e.g. automobile diesel engine, has sensor providing output that is used to regenerate exhaust gas emission control device using additional fuel during regeneration control mode... TSUIKI, TOYOMORI 被引量: 0发表: 2007年 Diesel engine air/fuel ratio controller for...
Consequently, this research introduced the stoichiometric air-fuel-ratio mode to the diesel vehicle and used the three-way conversion effect of a Diesel oxidation catalyst to assist the NOxreduction effect of Urea-SCR system. As a result, the diesel vehicle was able to meet SULEV category under...
This paper investigates the adoption of an innovative closed-loop control of the air/fuel ratio (AFR) in modern diesel engines. The in-cylinder AFR is in fact a critical quantity responsible for the formation of NO x and particulate matter emission. Two approaches are investigated for the desig...
STUDY OF VARIATION OF COMPRESSION RATIO AND AIR FUEL RATIO ON PERFORMANCE CHARACTERISTICS ON DIRECT INJECTED DIESEL ENGINEDiesel engines are one of the most efficient prime movers commonly available today. They are used to drive automobiles especially heavy vehi...
experimentally optimized a diesel engine, and they calibrated the landmarks of control points.15 Therefore, loop-up map is the mainstream in the parameter setting of engine control unit. However, fuel injection without feedback adjustment will cause instability during the transition period of ...

Diesel 14.6:1 Methanol 6.4:1 Ethanol 9:1 LPG 15.5:1 Those are the Air to Fuel ratios for the most common fuels, by mass, known as the Stoichiometric Ratio. The Ratios do not tell the full picture though. They are the perfect ratios for a well mixed air and fuel vapour. In an eng...
PROBLEM TO BE SOLVED: To dissolve problems that an air-fuel ratio can hardly be adjusted to a required air-fuel ratio by a choke system in an operating condition just after starting when an internal combustion engine is low in temperature at the time of starting, and thereby no stable runni...
designed a fuzzy controller in PDC structure for air management of diesel engines [34]. Ghaffari et al. designed a fuzzy control system to examine the air-fuel ratio of spark ignition engine [35]. Show abstract Modeling and control of diesel engines: A systematic review 2018, Alexandria ...
