Future government emission regulations have lead to the development and implementation of advanced aftertreatment systems to meet stringent emission standards for both on-road and off-road vehicles. T....
In nowadays diesel engine, the turbocharger system plays a very important role in the engine functioning and any loss of the turbine efficiency can lead to driveability problems and the increment of e....
Ion current sensors have been considered for the feedback electronic control of gasoline and diesel engines and for onboard vehicles powered by both engines, while operating on their conventional cycl....
The LNT(Lean NOx Trap) system has been developed for NOx reduction to meet Tier2Bin5 by using 2.2ℓ-diesel engine which was recently introduced by Hyundai Kia Motor company. The compression ratio was a....
The often-observed differences in nitrogen oxides, or NOx, emissions between biodiesel and petroleum diesel fuels in diesel engines remain intense topics of research. In several instances, biodiesel-f....
This paper presents a cylinder pressure-based control (CPBC) system for conventional diesel combustion with high EGR levels. Besides the commonly applied heat release estimation, the CPBC system is ex....
In modern production diesel engine control systems, fuel path control is still largely conducted through a system of tables that set mode, timing and injection quantity and with common rail systems, r....
Today's calibration process for ECU functions is often based on a wide variety of proprietary tools and individual expert knowledge of calibration engineers. Automatic calibration with an industrializ....
In this work we propose an automatic tuning method for the calibration of PID controllers of the idle speed functionality in Diesel engines. The tuning method is based on a closed-loop identification ....
The modern power train calibration process is characterized by shorter development cycles and a reduced number of prototypes. However, simultaneously exhaust aftertreatment and emission testing is bec....
Vehicles fueled by liquefied petroleum gas (LPG) are also required to provide high levels of engine torque and power, in addition to clean emissions for environmental friendliness, low fuel consumptio....
Signal processing incorporating Artificial Neural Networks (ANN) has been shown to be well suited for modeling engine-related performance indicators [ 1 , 2 , 3 ] that require multi-dimensional parame....
This paper identifies a select method for performing cylinder imbalance measurement, correction and diagnosis. The impetus is to address new U.S. Federal regulations that require the detection of exce....
Engine Electronic Throttle Control (ETC) systems are gaining success in high volume applications. This system helps to improve overall engine and vehicle performance, as well as facilitate the functio....
