The aim of this work, consisting of 9 individual, self-contained booklets, is to describe commercial vehicle technology in a way that is clear, concise and illustrative. Compact and easy to understand, it provides an overview of the technology that goes into modern commercial vehicles. Starting from the customer's fundamental requirements, the characteristics and systems that define the design of the vehicles are presented knowledgeably in a series of articles, each of which can be read and studied on their own. In this volume, Fuel Consumption and Consumption Optimization, the main focus is placed on the factors for optimizing consumption in the conventional vehicle. Fuel consumption can be optimized by four different factors: the technology of the vehicle, the conditions of its operation, the behavior of the driver and the maintenance and upkeep of the vehicle. These aspects are described in a way that is easily understood for training and practical application. 1 Preface Contents 978-3-662-66449-0_1 1 Fuel Consumption and Consumption Optimization 1.1 Fuel Consumption Optimization as an Economic Necessity 1.2 Fuel Consumption Optimization for the Environment 1.3 Energy Consumption Optimization for ALL Drive Systems 978-3-662-66449-0_2 2 Vehicle and Energy Loss 2.1 Motion Resistance 2.2 Energy Consumption in a Vehicle with Combustion Engine 2.3 Energy Consumption of a Vehicle with an Electric Drivetrain 2.4 Factors that Influence Consumption 978-3-662-66449-0_3 3 Vehicle Technology 3.1 Engine 3.1.1 E-machine 3.2 Drivetrain 3.2.1 Transmission 3.2.2 Axles 3.3 Auxiliary Consumers 3.4 Tires and Rolling resistance 3.5 Aerodynamics 3.5.1 Aerodynamics of the Driver’s Cab 3.5.2 Optimization of Aerodynamics 3.6 Technical Aids for the Driver 3.6.1 Predictive Systems 3.7 Curb Weight 3.8 Full Trailers, Semitrailers and the Load 978-3-662-66449-0_4 4 Operating Conditions of the Vehicle 4.1 Topography of the Route 4.2 Weather and Temperature 4.2.1 Vehicle with a Warmed-Up Engine 4.3 Traffic 4.3.1 Convoy Driving—Platooning 4.4 Speed 4.5 Loading 4.6 Consumption Reductions Through Optimized Operating Conditions 4.7 Reduced Consumption Through Optimized Logistics Concepts 978-3-662-66449-0_5 5 The Influence of the Driver on Energy Consumption 5.1 Consumption Values of New Vehicles 978-3-662-66449-0_6 6 Maintenance of the Vehicle and Service Fluids 6.1 Tire Pressure 6.2 Energy Content of the Fuel 6.3 Lubricating Oils 978-3-662-66449-0_7 7 Concluding Remarks on the Topic of Energy Consumption 7.1 Measurement of the Fuel Consumption 7.2 Effect of External Factors on Fuel Efficiency 7.3 Scope of the Energy Efficiency Considerations 1 (1) Comprehension Questions Abbreviations and Symbols References Index The aim of this work, consisting of 9 individual, self-contained booklets, is to describe commercial vehicle technology in a way that is clear, concise and illustrative. Compact and easy to understand, it provides an overview of the technology that goes into modern commercial vehicles. Starting from the customer's fundamental requirements, the characteristics and systems that define the design of the vehicles are presented knowledgeably in a series of booklets, each of which can be read and studied on their own. In this volume, Fuel Consumption and Consumption Optimization, the focus is placed on the factors for optimizing energy consumption of the vehicle. Both conventional vehicle running on Diesel fuel and vehicles with electric drivetrains are covered in this booklet. Energy consumption can be optimized by four different factors: the technology of the vehicle, the conditions of its operation, the behavior of the driver and the maintenance and upkeep of the vehicle. These aspects are described in a way that is easily understood for training and practical application
