Abstract. Objective: To study the technology of auxiliary motor starting and stopping of the direct injection gasoline engine, and analyze the effect of the idle start stop system and oil saving energy. Method: the fuel saving effect analysis of the fuel saving effect of the system is analyzed by the multiple model. Process: we in the downtown and suburban stop system to open and close the NEDC fuel consumption record results, typical conditions stop system NEDC drive cycle fuel saving effect curve analysis, and instantaneous fuel consumption curve comprehensive comparative analysis. Conclusion: through data analysis, we can know that the average vehicle parking time is more than 9S, the system can reduce the fuel consumption of vehicles; for these two models, starting fuel consumption is high.

“…The exhaust system includes pipes, various types of catalytic converters, soot filters, and dosing elements. In the context of system simulation, transient zero-dimensional simulation models have been established (Wanker et al 2008). The main phenomena to be represented by the model are the flow through the components, mass and heat transfer between gas and surfaces, the transient thermal behavior of the components, the transient storage behavior of surface reactions, and soot filtration as well as the catalytic pollutant reduction in heterogeneous reactions.…”

System simulation is a part of the overall field of systems engineering and provides quantitative results to verify and validate the architecture and parameters of a system under development. In the meantime, system simulation is a wellestablished activity in the automotive development area and covers a broad range of applications over the whole development process from system architecture definition, component dimensioning up to virtual testing and calibration. In all of these steps, simulation helps the systems engineer find the best choice of system architectures, evaluate the component target characteristics, define the control logic and parameters, and support the individual tests. Thanks to system simulation, proper system function can be confirmed in early phases of development, which minimizes the number of cost-intensive development loops. In addition, verification and validation and calibration tasks can be frontloaded to reduce overall development time. This chapter focuses on the setup of different physical domain models and how they are linked together. The modeling approaches of the individual domains and simulation management are discussed.

“…A dual fuel model requires a 6-species (two times three species) transport approach to track the properties of both fuels. The 6-species approach is computationally less demanding than the application of general species transport methods (see Wanker et al [7]) including chemical equilibrium calculation during the run-time. One important requirement is real-time capability therefore computanional performance is a decisive factor.…”

More and more, alternative fuels, fuel mixtures and dual-fuel engines are gaining in importance. This means a huge challenge to thermodynamic modeling of combustion and species transport. The computational performance is reached by an optimized filling and emptying approach applying tailored models for in-cylinder combustion and species transport in the gas path. The impact of the thermodynamic characteristics induced by the different fuels is described by an appropriate set of transport equations in combination with specifically prepared property databases. The accuracy of a lumped fuel approach is compared for a six, three and one species transport. The simulations are performed with a 6 cylinder medium speed engine. The real-time factor of this engine is in the range of 0.2 for all species transport approaches, what enables this method to support HiL based function development and calibration.
