In the modern world, one of the largest concerns is the ever depleting supply of oil. The automotive industry is especially impacted. In recent years the price of gasoline has fluctuated substantially and the price of crude oil has reached record highs. The high price of gasoline coupled with the uncertainty of its availability and future price have put a high priority on fuel economy of an eng...

Almost three quarters of the hydrocarbon (HC) emissions emitted by an automobile in a typical drive-cycle are produced during the first three minutes of its operation called the coldstart period. In this paper, we propose a way to decrease cold start emissions. A Model-Based paradigm is used to aid the generation of an efficient controller. The controller is built around a mean value engine mod...

In order to solve the environmental pollution problem and the energy depletion problem in recent years, a control technology that improves the quality of engine in automobile is demanded. However, thanks to the developments of electrical and electronic mounting technology, advanced control of the power train has become possible. This paper presents an application of “Large scale database-based ...

This study developed the simulator for knocking analysis that enables knocking discrimination and engine balance correction applicable to the ECU exclusive to the industrial CRDI engine. The purpose of this study is to provide the driver-oriented diagnostic services that enable drivers to diagnose vehicles directly by developing diagnostic devices for vehicles with the use of the results of the...

Data obtained from Nary calibration tests of an 18-cylinder, two-row, radial engine of 8350-cubic-inch displacement and a 14-cylinder, two-row, radial engine of 2600-cubic-inch displacement {carburetor types) were analyzed to show the correlation between the air consumption of these engines and the parameters that evaluate the air consumption from intake-manifold temperature and pressure, exhau...

Cytoskeletal motor proteins move on filamentous tracks by converting input chemical energy that they derive by catalyzing the hydrolysis of ATP. The ATPase site is the analogue of an engine and hydrolysis of ATP is the analogue of burning of chemical fuel. Moreover, the functional role of a segment of the motor is analogous to that of the transmission system of an automobile, which consists of ...

Computational Fluid Dynamics is used to assess the thermal (heat transfer) performances of an automobile engine considering different grille opening and closing degrees. For this purpose entire vehicle modelled three fundamental aspects are examined, namely, open area air intake grille, position upper lower grilles their shape. The results show that have some influence also on aerodynamic chara...

Real{time systems are de ned as those systems in which the correctness of the system depends not only on the logical result of computation, but also on the time at which the results are produced. Real-time systems span a broad spectrum of complexity from very simple microcontrollers (such as a microprocessor controlling an automobile engine) to highly sophisticated, complex and distributed syst...
