“…The engine is represented by a second-order mean value model similar to that of Keynejad and Manzie (2011) and considers fluid, thermal, and mechanical domains. It calculates the intake manifold pressure p im , exhaust port gas temperature T cyl , and fuel mass flow rate Figure 1 Structure of the combined engine, emissions, exhaust, and after-treatment system model.…”

“…Mean value engine models (MVEM) (e.g., Aquino, 1981;Cho and Hedrick, 1989;Guzzella and Onder, 2004;Hendricks, 1997;Keynejad and Manzie, 2011;Moskwa, 1988) are a well established class of low-order, physics-based models. They simulate dynamics of orders greater than a single cycle while replacing faster dynamics with algebraic relationships or static maps.…”

Although the Stirling engine was invented in 1816, this heat engine still continues to be investigated due to the variety of energy sources that can be used to power it (e.g., solar energy, fossil fuels, biomass, and geothermal energy). To study the performance of these machines, it is necessary to develop and simulate models under different operating conditions. In this paper, we present a one-dimensional dynamic model based on components from Trnsys: principally, a lumped mass and a heat exchanger. The resulting model is calibrated using GenOpt. Furthermore, the obtained model can be used to simulate the machine both under steady-state operation and during a transient response. The results provided by the simulations are compared with data measured in a Stirling engine that has been subjected to different operating conditions. This comparison shows good agreement, indicating that the model is an appropriate method for transient thermal simulations. This new proposed model requires few configuration parameters and is therefore easily adaptable to a wide range of commercial models of Stirling engines. A detailed analysis of the system results reveals that the power is directly related to the difference of temperatures between the hot and cold sources during the transient and steady-state processes.

“…It is due to the fact that the fuel enrichment is reduced and higher IMEP could be obtained [17]. Keynejad develops a model framework for capturing the temperature transients and gaseous concentrations throughout the engine, with improved performances and lower emissions as the main benefits (if economy and emissions at every point in the working cycle are scrutinized, the cold start operation of the engine becomes more critical and the constant temperature assumption is limiting) [18]. Chan develops a model that is capable of predicting the exhaust gas temperatures along the exhaust pipe and across the catalyst monolith, both spatially and temporally; and experiments with the conversions of toxic carbon monoxide and unburned hydrocarbons to harmless carbon dioxide and water at the catalytic converter [19].…”

The present paper shows research made on a spark ignited engine with port fuel injection in different operation conditions in order to improve the comprehension about the cold start sequence, acceleration when changing the gear ratios, quality of combustion process and also any measures to be taken for pollutant reduction in such cases. The engineering endeavor encompasses the pollutants investigation during the operation time of gasoline supplied engine with four inline cylinders in different conditions. The temperature and any other parameters were measured with specific sensors installed on the engine or in the exhaust pipes. All the data collected has been evaluated using electronic investigation systems and highly developed equipment. In this manner it has enabled the outline of the idea of how pollutants of engine vary in different operating conditions. Air quality in the everyday environment is very important for the human health, and thus the ambient air quality has a well-known importance in the European pollution standards and legislation. The high level of attention directed to the pollution problem in the European lifestyle is a driving force for all kinds of studies in the field of the reduction of engine emission.
