In order to investigate the effects ethanol-diesel blends and altitude on the performance of diesel engine, the comparative experiments were carried out on the bench of turbo-charged diesel engine fueled with pure diesel (as prototype) and ethanol-diesel blends (E10, E15, E20 and E30) under different atmospheric pressures (81kPa, 90kPa and 100kPa). The experimental results indicate that the equivalent...
In order to investigate the effects ethanol-diesel blends and altitude on the emissions of diesel engine, the comparative experiments were carried out on the bench of turbo-charged diesel engine fueled with pure diesel (as prototype) and ethanol-diesel blends (E10, E15, E20 and E30) under different atmospheric pressures (81kPa, 90kPa and 100kPa).

A single cylinder vertical air-cooled diesel engine was modified to use Methanol fuel mode to study the performance, emission, and combustion characteristics. The primary fuel, Methanol with air, compressed, and ignited by a small pilot spray of diesel. Dual fuel engine showed a reduction in oxides of Nitrogen and smoke in the entire load range. However, it suffers from the problem of poor brake thermal...
The effects of Methyl-Tetra-Butyl-Ether (MTBE), as an additive, on the performance, combustion and the emission characteristics of a compression ignition (CI) engine are investigated experimentally. The experimental set-up consists of a diesel engine coupled with an eddy current dynamometer, AVL Di-gas analyser, AVL smoke meter and a data acquisition system is used. The di-gas analyzer is used to...
The numerical simulation was carried out by building methane-diesel fuel model at the base of physical model and basic control equation of hydrodynamics, by adopting non-premix combustion method, by simplifying combustion as blends, and by calculating blend fraction. Furthermore, its combustion press field, temperature field and velocity field were analysed. Finally, the experimental results indicated...
In this paper, the simulation of diesel fuel injection system using different kinds of delivery valves is studied. And the performance differences of the fuel injection system under different spraying pressure are compared. The influence of three basic delivery valves, which are damping valve, constant pressure delivery valve and constant volume delivery valve, to pump pressure, nozzle pressure, injection...
Over the next several decades, substantial reductions in greenhouse gas emissions from transportation will be required. The targets-an 80% reduction by 2050-are challenging. Thus, we need quantitative methodologies for assessing the impact of changes in vehicle technology and use, and of fuels, on transportation energy consumption and GHG emissions. This paper describes an appropriate methodology...
Electronics has greatly contributed to the development of internal combustion engine. This progress has resulted in reducing environmental degradation, and yet continuing to support improvements in performance. Regarding gasoline engine, a considerable step forward has been achieved by Common Rail (CR) technology able to exactly regulate the injection pressure during whole engine speed range. As a...
This paper describes the properties and application of a new composite oxygenated fuel, named as FHYJ, for an compression-ignition engine. First, the properties of FHYJ, and FHYJ-diesel fuel blend were studied. Furthermore, experimental tests were carried out to study the combustion performances and emissions of a four-cylinder direct injection diesel engine fuelled with the blends compared with those...
On a diesel engine of generating unit, investigated the control strategy of the diesel-water coal slurry blends combustion and the speed of the diesel engine, and developed an electronic control unit. The experimental results show that this control strategy can limit the engine speed, output voltage and frequency of the generating unit to a regulated range, and keeping them steadily.
Dimethyl ether (DME) can be used as a clean high-efficiency compression ignition fuel with reduced NOx, SOx, COx and particulate matter. The subject of this work is to investigate of the injection characteristics of diesel and DME within the same specifications of injection system. The mathematical model is established for the conventional pump-pipe-nozzle fuel injection system and numerical simulation...
The BP algorithm and the theory of the artificial neural network are applied in the research of the fault diagnosis of diesel engine fuel injection system. Through study on the diesel engine fuel injection system's work characteristics and the vibration signal characteristic parameter, gives the method and the step of gathering the vibration signal, set the parameter of BP neural network reasonably,...
This paper presents the results of investigations carried out on a single cylinder, direct injection, water cooled diesel engine operating on diesel, straight vegetable oils (Thumba oil and Neem) and 20% biodiesel blend of Thumba oil. The experiment covered a range of loads. Results show that Thumba oil can be used as an alternative fuel with better performance and lower emissions compared to Neem...
The paper establishes a mathematical model to describe the rotation speed regulation process of a marine diesel engine system. Then an adaptive control system with fault treatment algorithm is designed for the control of the rotation speed. The adaptive control system makes self-organizing through modification of its weighted values which are determined through correlative search, as well as a coefficient...
An experiment / pilot to improve emission factor of the mobile transport carried out and the below results came up. For transportation sector inventory, we found that major user of the fuels in 1990 was auto-transportation. But this condition has changed and by 1996 the biggest user of fuels became the machinery and vehicles that used in mining sites using about 40 per cent of overall diesel consumption...
