This work was one of the tasks of the Manufacturing2Client project, whose objective was to develop a frontal deflector to be commercialized in the automotive industry, using new project and manufacturing methods. In this task, in particular, it was proposed to develop the ability to predict computationally the aerodynamic influence of flow in vehicles, in an effort to reduce fuel consumption in...

Reducing fuel consumption is a major goal for the aviation community due to environmental concern and fuel price uncertainty. The Federal Aviation Administration (FAA) is currently developing and implementing Air Traffic Management (ATM) technologies to ensure reliable operational performance that is robust to delays caused by congestion and weather. These technologies will reduce planned and u...

The petroleum product has seen a drastic demand in the recent past. Biofuels are the only solution to overcome this power crisis. In the view of sustainable energy development, biodiesel and its additives have become the best options for fossil fuel-based engines. In this work, a biodiesel mix was used to show the possible utilization of different biofuels. An experimental investigation was car...

The environment has recently led to very severe regulations on fuel consumption and exhaust emissions. I propose a scheme to minimize rate of fuel consumption for a direct fuel injection engine used by combination with a continuously variable transmission. Target values for the engine and the transmission which minimizes fuel consumption ensuring driving performance is calculated based on the n...

Fuzzy logic is a rule based system which is implemented using if then rules. For example two parameters say x & y are varied in order to know which parameter effects the fuel efficiency. This paper explores in particular the use of fuzzy logic in the Efficient estimation of fuel consumption. We present an intelligent Engine Control Unit (ECU) that controls a series of actuators on an internal c...

Non-road diesel engines are significant contributors to air pollution in the United States (USEPA, 2004). These engines emit particulate matter (PM), nitrogen oxides (NOx), sulfur dioxide (SO2), and other pollutants. The Clean Air Non-road Diesel Rule was put in place to reduce emission levels from agricultural, construction, and industrial diesel powered equipment. This rule calls for a reduct...

This Paper proposed the estimation method of fuel consumption from vehicle information through OBD-II. We assumed RPM, TPS had a relationship with fuel consumption. We got the output as fuel-consumption from a vehicle RPM, TPS as input by using polynomial equations. We had modeling as quadric function and surface function with OBD-II data and fuel consumption data supported by automotive compan...

The possibilities to simulate fuel consumption and optimize a vehicle’s powertrain to fit to the customer’s needs are great strengths in the competitive bus industry where fuel consumption is one of the main sales arguments. In this master’s thesis, bus specific powertrain component models, used to simulate and predict fuel consumption, are validated using measured data collected from buses. Ad...
