Development of a pure methanol fuel car

Abstract: Methanol as a fuel for spark ignition engines offers a lot of advantages in comparison to gasoline. Results of a prototype passenger car fueled with pure methanol show promising aspects of lower energy consumption, higher energy output and more favorable emission figures. Modifications on the engine are limited, the unfavorable cold start and warm up behavior of pure methanol can be eliminated by the use of suitable additives. /GMRL/

Biodiesel from rapeseed oil of Turkish origin as an alternative fuel

Abstract: The crude rapeseed oil was transesterified using methanol and using sodium hydroxide as a catalyst, and the varieties affecting the monoester yield were investigated. The methyl ester fuel called Biodiesel, produced under the determined optimum reaction conditions, was tested according to the standard methods for its fuel properties. Biodiesel fuel properties were found to be very close to those of Grade No. 2-D diesel fuel.

Fuel lubricated sliding mechanism

Abstract: There is provided a fuel lubricated sliding mechanism including a pair of sliding parts having respective sliding portions slidable relative to each other in the presence of fuel. At least one of the sliding portions of the sliding parts has a hard carbon coating formed with a hydrogen content of 30 atomic % or less. The fuel is selected from the group consisting of gasoline, light oil, alcohol fuel, biodiesel fuel and GTL fuel.

Vehicle Emissions and Fuel Economy Effects of 16 % Butanol and Various Ethanol Blended Fuels (E10, E20, and E85)

Abstract: Due to various concerns involving conventional gasoline, there has been a growing interest in the study of alternative fuels and their use in the automotive industry. There has been particular interest in the fuel effects of varying levels of ethanol blends and other alternative fuels on vehicle emissions and fuel economy. This paper will examine and compare both exhaust emissions and fuel economy for various ethanol blended fuels, and a 16 % butanol blended fuel. The results were generated using the U.S. Federal Test Procedure. Vehicles that are certified to U.S., European, and Brazilian government standards were tested. These vehicles include a flex fuel capable (FFV) 2007 Chevrolet Zafira (E100-FFV), 2007 Chevrolet Suburban (E85-FFV), 2007 Saab 9-5 BioPower (E85-FFV), 2007 Chevrolet Suburban, 2007 Pontiac G5, and a 2006 Pontiac G6. The fuels examined were E10, E20, E85, and Bu16. Each fuel was splash blended to make up the proper finished fuel blend. Fuel economy and emissions results from these fuels were compared with those from Tier 2 Emissions Certification fuel.

New generation of automotive sensors to fulfil the requirements of fuel economy and emission control

Abstract: The new passenger car regulations for future emission levels and the increasing demands for fuel economy have led to strong efforts to develop new engine-management systems, exhaust-treatment technologies and new automotive sensors. In this paper a new generation of automotive sensors that help to fuffil the requirements for fuel economy and emission control is presented. The demands on these new sensors include the following improvements: (i) better resolution, higher accuracy and better long-term stability, especially under severe environmental conditions; (ii) good performance at high temperature (e.g., up to 150 °C for rotational speed sensors and 1100 °C for exhaust gas sensors); (iii) short response times for dynamic cylinder-selective measurements; (iv) more efficient compensation methods by measuring different physical parameters. This talk gives an overview on the physical principle, the design, the technology and the application of a new generation of automotive sensors. Representing a potential ‘high-volume’ sensor, we report on an active rotational speed sensor to measure the angular position of the crankshaft. This sensor is based on a newly developed differential Hall IC. The high angular resolution allows more accurate ignition timing as well as ‘misfiring’ detection to be achieved. For the precise control of combustion in future engine-management systems, an ‘air flow sensor’ for cylinder-specific carburation, a ‘combustion pressure sensor’ for thermodynamic calculation of the combustion and a ‘fast exhaust gas sensor’ for cylinderselective exhaust-gas analysis can be used. This report will focus on the development of a fast oxygen sensor to measure the oxygen partial pressure of the exhaust gas. As an example of a smart sensor, an ‘alcohol fuel sensor’ for alternative fuel concepts is introduced. This sensor is a key component of a flexible fuel system which can be run on arbitrary mixtures of gasoline and methanol. This sensor measures three physical parameters: the capacitance, the conductivity and the temperature, in order to determine the methanol/gasoline ratio in the fuel rail with high accuracy.
