The launch of the new 1.8 l TFSI engine marks the third generation of the successful four-cylinder gasoline engine family from Audi. It has been completely revised in order to meet ambitious CO2 targets and ensure compliance with future Euro 6 emissions standards. The new generation features numerous innovative technologies, including an exhaust gas cooling system integrated into the cylinder h...

The topic of this paper is the object oriented modeling of a Common Rail Direct Injection System of a gasoline engine. The injection system of a gasoline engine is described; the main functional elements are detailed and an object oriented implementation using the Modelica language is proposed. The availability of a fast and easily reconfigurable simulator allows to study how different parts of...

Observer Design for Downsized Gasoline Engine Control Using 1D Engine Simulation — This study presents the use of a 1D engine model for the control design of a twin-scroll turbocharged gasoline direct injection 2.0 l i4 engine with twin camphaser. This virtual engine is used for the development of the in-cylinder mass observer which is a crucial issue for the control of such an engine because o...

A computer controlled direct gasoline fuel injection (DGI) system has been modeled, programmed and constructed for a four-stroke SI engine. Locally available materials have been used for this experimental model. All the old model vehicle were equipped with carburetor for air fuel mixing and later on electronic fuel injection system has been introduced for maintaining better air fuel ratio and m...

In this study, fuzzy expert system (FES) was designed by using Matlab software for determination of performance and emission characteristics of a gasoline engine which is Briggs and Stratton Vanguard trademark, a cylinder, cylinder volume 182 cm. In the designed FES, intake valve opening advance (advance-) and engine speed (nd/d) were determined as input parameters whereas torque (Me-Nm), power...

Fuel quality is an important indicator for the suitability of alternative fuel utilization in internal combustion (IC) engines. In this paper, light naphtha and fusel oil have been introduced as additives local low octane gasoline to operate a spark ignition (SI) engine. Investigated samples prepared based on volume denoted GN10 (90% 10% naphtha), GF10 oil), GN5F5 gasoline, 5% oil) addition G10...

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...

Development of Gasoline Engine Management Systems control features Tata Consultancy Services in alliance with a leading Tier-1 supplier has developed control and diagnostic features to be implemented for a Gasoline Engine Management System (EMS) that will be used in a passenger car that meets EU4 emission norms. From the high level requirements provided by the Tier-1 , the control features deve...

The engine and its exhaust flow behaviors are investigated in a turbo-charged gasoline direct injection engine under simulated cold-fast-idle condition. The metrics of interest are the exhaust sensible and chemical enthalpy flows, and the exhaust temperature, all of which affect catalyst light off time. The exhaust sensible enthalpy flow is mainly a function of combustion phasing; the exhaust c...
