Hybrid vehicle techniques are widely studied recently because of their potential to significantly improve the fuel economy and drivability of future ground vehicles. Due to the dual-power-source nature of these vehicles, control strategies based on engineering intuition frequently fail to fully explore the potential of these advanced vehicles. In this paper, we will present a procedure for the ...

Fuel properties of loofah oil and its ethyl ester blended with diesel were experimentally determined. Biodiesel blends (10, 20, 30, 40, 50, 60, 70, 80, 90 and 100%) of loofah oil and its ethyl ester by volume with diesel was used. The fuel properties of the biodiesel blends were determined according to American Society for Testing and Materials (ASTM) standards. Pure Automotive Gas Oil (AGO) wa...

Diesel engines due to the better fuel economy have been widely used in automotive area. However, the limited reserve of fossil fuel and deteriorating environment have made scien‐ tists seek to alternative fuels for diesel while keeping the high efficiency of diesel engine. Fuel consumption is expected to increase from 86 million barrels per day to 112 million bar‐ rels per day by 2035 according...

Various environmental regulations put ever stringent requirements on the automotive industry as a part of solution to the problem of global warming and climate change. Engine emissions are influenced, among others, also with quality of fuel and air mixing process. Auto ignitability of fuel in cylinder depends on detailed chemical composition of the fuel as well as on the evolution of the therma...

I NCREASING DEMAND on pollution reduction is driving innovation in clean energy devices. Among these, fuel cells are regarded as one of the most promising technologies, due to their efficiency, compactness and reliability. However, to achieve the widespread use of hydrogen, which is combustible, -and the resulting “hydrogen economy” -, there are critical technological issues that have to be sol...

The quest for improved fuel efficiency and environmental friendliness is transforming automotive vehicle design. In addition to new energy sources and management, new powertrain technologies offer increased flexibility in the spatial arrangement (packaging) and exterior shape (styling) of a vehicle. Design choices in packaging and styling are closely linked to consumer preferences, particularly...

Fuel consumption reduction is one of the main challenges in the automotive industry due to its economical and environmental impacts as well as legal regulations. While fuel consumption reduction is important for all vehicles, it has larger benefits for commercial ones due to their long operational times and much higher fuel consumption. Optimal control of multiple energy buffers within the vehi...

This paper presents a mathematical model of internal combustion engine dynamics namely air, fuel and rotational dynamics. Engine under study is naturally aspirated spark ignition four-stroke internal combustion engine with electronic fuel injection system. The purpose of model development is to provide a simple system level model for design of model-based control methods and fault diagnostics. ...

Theoretical models play an important role in the design of engine control and diagnostic systems, allowing to reduce development time and costs. The paper describes a control-oriented theoretical model for the simulation of an automotive Diesel engine built up using a “simulation library” developed in Simulink environment. Library blocks, defined for engine components and subsystems, were assem...
