312 pages and more than 600 illustrations and charts, size 8.25 x 10.75 inches. When the new Porsche 914 was announced in 1969 (as a 1970 Model), Floyd Clymer had already published a number of Porsche and VW manuals. Those publications included manuals for the Porsche 356 and 912, the VW Beetle, the 1500cc/1600cc Square-back/Hatch-back and the Transporter/Bus. Consequently, it was no surprise that Floyd would begin preparation of a 914 shop manual. Floyd was able to complete the Porsche 914 manual in record time, mainly because he was able to re-use most all of the 'mechanical' pages from his previously published Porsche and VW manuals. The only entirely 'new' section that he had to prepare was a chapter for the body components as they were uniquely different from any previous Porsche or VW model. Unfortunately, due to his untimely passing in early 1970 the 914 manual, although complete, remained unpublished and obviously, it only covered the early 914/4 1.7 liter and the 914/6 2.0 liter engines. We have taken that original manual and updated the information to cover the later 4 cylinder 1.8 liter and 2.0 liter models through 1976. While much of the general data is shared between both the 4 and 6 cylinder 914 variants, owners of the 6-cylinder 914 model are encouraged to read any individual chapter in its entirety, as it may include information that is specific to the 6-cylinder version.

This book provides a thorough and fresh treatment of the control of innovative variable-geometry vehicle suspension systems. A deep survey on the topic, which covers the varying types of existing variable-geometry suspension solutions, introduces the study. The book discusses three important aspects of the subject:¿ robust control design;¿ nonlinear system analysis; and¿ integration of learning and control methods.The importance of variable-geometry suspensions and the effectiveness of design methods implemented in the autonomous functionalities of electric vehicles¿functionalities like independent steering and torque vectoring¿are illustrated. The authors detail the theoretical background of modeling, control design, and analysis for each functionality. The theoretical results achieved through simulation examples and hardware-in-the-loop scenarios are confirmed. The book highlights emerging ideas of applying machine-learning-based methods in the control system with guarantees on safety performance. The authors propose novel control methods, based on the theory of robust linear parameter-varying systems, with examples for various suspension systems.Academic researchers interested in automotive systems and their counterparts involved in industrial research and development will find much to interest them in the eleven chapters of Control of Variable-Geometry Vehicle Suspensions.

Marvin Sascha Wahl presents the possibilities for optimising diesel engine combustion. In the advanced process of partially premixed diesel combustion, nitrogen oxide and soot emissions can be minimised at the same time. A new feature is the possibility of applying this strategy up to 2000 revolutions and 10 bar indicated mean pressure. In this work, various effective parameters are also compared and correlated with each other. A final comparison with conventional diesel combustion shows the advantages and disadvantages and evaluates them.

This book deals with the simulative prediction of efficiency and CO2-emissions of future powertrain systems for the year 2040. For this purpose, a suitable simulation environment is first created. This is followed by a technology extrapolation of all relevant powertrain systems, for example: combustion engines, electric drives, fuel cells as well as all relevant additional components. These components are then used to build 57 vehicle variants for the simulation. Finally, extensive simulations of the vehicle variants are carried out, evaluated and compared. Comprehensive tables of results are available for all simulated vehicle variants. The evaluations are of interest to anyone concerned with energy consumption and CO2-emissions of future vehicles.

Marco Scheffmann stellt einen neuartigen multikriteriellen Lösungsalgorithmus für die Erzeugung optimaler Datensätze von Fahrzeugsteuergeräten vor. Im Gegensatz zu verbreiteten, zumeist evolutionären Ansätzen wendet der Autor hier einen Ansatz des bestärkenden Lernens an. Infolge der eigenständigen Entwicklung zielgerichteter Handlungsstrategien kann damit auf sonst häufig eingesetzte vorangestellte Methoden der statistischen Versuchsplanung und der Metamodellbildung verzichtet werden. Zur subjektiven Betrachtung von optimierten Datensätzen dient ihm die echtzeitfähige Verkopplung der vollbeweglichen Fahrsimulation mit virtualisierten Steuergeräten. Seine abschließende Probandenstudie bestätigt die Ergebnisse des vorgestellten methodischen Ansatzes.

Zur Steigerung der Genauigkeit und Prognosegüte der Motorprozessrechnung entwickelt Sven Fasse den aktuellen Stand der Modellierung von Ventildurchfluss und Brennraumturbulenz.

174 pages with 145 illustrations, diagrams and charts, size 6-5/8 x 10-1/4 inches. This is a publication for those Ferrari enthusiasts that are tired of oversized and often overpriced coffee table books filled with page after page of photos of red Ferrari's and not much else.This book contains all the technical data and statistics for the majority of the 1948 to 1958 Ferrari road and race cars. It was compiled by a knowledgeable author who lived in Modena at the time that these cars were being constructed, who was personally acquainted with Enzo Ferrari and had access to the factory documents during that time period. It includes the author's road test experiences, technical specifications, tune up, adjustments, maintenance and repair information, detailed technical drawings, exploded views, wiring diagrams and lubrication charts. This book is a 'must have' for any Ferrari enthusiast or lucky owner of one of these early cars and should be in the library of any true Ferraristi. Originally published by Floyd Clymer in 1960 under the similar title of 'The Ferrari Owner's Handbook', its description left much to be desired. For example, of the 174 pages there are 90 pages that are much closer to a repair and maintenance manual. Consequently, it's more of a technical manual than a handbook.There are seven sections that cover both the road and race cars constructed by Ferrari from 1948 to 1958. Section 1 - The authors driving experiences of the Type 166, Type 342 and 340 America and Type 375 America.Section 2 - Specifications for 41 road and race cars constructed by Ferrari from 1948 to 1958. Section 3 - Repair, Maintenance and tune up information.Section 5 - Valve Timing and Carburetor data.Section 6 - Acceleration times.Section 7 - Detailed component drawings, exploded views, Wiring Diagrams, Lube charts etc.
