“…In this way, the system transient response is faster if compared to a conventional turbocharged system, and a reduction in fuel consumption over driving cycles characterized by frequent transient operation is obtained. These conclusions are confirmed by Katrasnik et al [12].…”

“…Generally, in order to maintain high generation efficiency by EG, it is necessary to extract the area of an operation point (load and number of rotations) as much as possible. Moreover, if large load fluctuation is added to EG, tens of seconds are required to stabilize the power from several seconds [5]. Therefore, EG is used for base load operation in this paper, and the fuel cell distributed in each house examines the micro-grid that controls the number according to the amount demanded.…”

“…Katrašnik et al [110,111] studied the improvement in transient response of a six-cylinder, turbocharged diesel engine, rated at 162 KW at 2400 rpm, via the use of an electrically assisted turbocharging system too. This proved satisfactory as long as the electric motor possesses high torque to mass moment of inertia ratio.…”

Study and modeling of transient operation is an important scientific objective. This is due to the fact that the majority of daily vehicle driving conditions involve transient operation, with non-linear situations experienced during engine transients. Thus, proper interconnection is needed between engine, governor, fuel pump, turbocharger and load. This paper surveys the publications available in the open literature concerning diesel engine simulations under transient operating conditions. Only those models that include both full engine thermodynamic calculations and dynamic powertrain modeling are taken into account, excluding those that focus on control design and optimization. Most of the attention is concentrated to the simulations that follow the filling and emptying modeling approach. A historical overview is given covering, in more detail, research groups with continuous and consistent study of transient operation. One of the main purposes of this paper is to summarize basic equations and modeling aspects concerning in-cylinder calculations, friction, turbocharger, engine dynamics, governor, fuel pump operation, and exhaust emissions during transients. The various limitations of the models are discussed together with the main aspects of transient operation (e.g. turbocharger lag, combustion and friction deterioration), which diversify it from the steady-state. Some of the most important findings in the field during the last 30 years are presented and discussed. The survey extends to special cases of transient diesel engine simulation, such as second-law analysis, response when the turbocharger compressor experiences surge, and whole vehicle performance. Several methods of improving transient response are also mentioned, based on the various simulations. An easy-to-read tabulation of all research groups dealing with the subject, that includes details about each model developed and engines/parameters studied, is also provided at the end of the paper.
