Abstract:
The paper presents the experimental test results of a common rail injection system operating with biodiesel and the diesel fuel. The three fuel split injection strategies were implemented to investigate the effects made by biodiesel and a fossil diesel fuel on the history of injector inlet pressure and the injection rate. In addition, the three intervals between split injections and the different injection pressures were used to obtain more information about the studied subjects. The obtained results showed that the peak mass injection rates of the main injection phase were slightly higher whe

Abstract: For a diesel engine, fuel pressure time setting and calibration are very important parameters, which influence and increase the engine efficiency, performance, emissions, and combustion. Other injection parameters affecting engine performance are rate of injection, injection pattern, number of injections etc. A single cylinder research engine was used to experimentally determine the effects of fuel injection strategies and injection timings on engine combustion, performance and emission characteristics.

Engine experiments were carried out to study the impact of multiple pilot injections of a diesel fuel on dual-fuel combustion with a premixed ethanol fuel, using compression ignition. Because of the contrasting volatility and the reactivity characteristics of the two fuels, the appropropriate scheduling of pilot diesel injections in a high-pressure direct-injection process is found to be effective for improving the clean and efficient combustion of ethanol which is premixed with air using a low-pressure port injection.

The performance and emissions from diesel engines are greatly influenced by the degree of atomization of the fuel spray.

This study successfully investigated the engine performance and emission characteristics of a dual injection system that uses both gasoline and ethanol fuels. The study utilized a microcontroller-based control system (PGM-FI) to substitute ethanol fuel injection for gasoline injection. Ethanol fuel was injected at the inlet with three different pressures: 1.0 bar, 1.2 bar, and 1.4 bar, while gasoline injector pressure was fixed at 2 bar. Results showed that substituting ethanol injection with a pressure of 1 bar resulted in a slight decrease in torque and power, but it was the best compared to

The physical properties of the fuel, such as density, viscosity, surface tension, and bulk modulus of elasticity, affect many aspects of the diesel injection process. The effects of these fuel properties on the fuel pressure in the high-pressure line, rate of injection, leakage, spray penetration, and droplet size distribution were determined experimentally. The mechanism of spray development was investigated by injecting the fuel into a high-pressure chamber. A pulsed Malvern drop-size analyzer, based on Fraunhofer diffraction, was utilized to determine droplet size ranges for various fuels.

Abstract:
This study investigates the feasibility of injecting a premixed air and fuel charge into the precombustion chamber (PCC) of a Cooper-Bessemer GMV-4TF 2-stroke lean-burn natural gas engine. The primary ob-jectives are to enhance combustion stability, reduce emissions, and address the challenges associated with stratification within the PCC. Computational fluid dynamics (CFD) simulations were conducted to evaluate both ideal and practical premixed scenarios. The ideal premixed scenario aimed to achieve improved ho-mogeneity and faster flame propagation. Low-pressure premixed injections were test

Abstract:
High-pressure fuel injection has become an important retrofit technology for lowering emission and fuel consumption in large bore natural gas engines. As emissions regulations become more stringent, the need for further reductions in pollutant emissions and fuel consumption is apparent. One aspect of high-pressure fuel injection where there is still room for improvement is the nozzle. The nozzle can both redirect and accelerate the fuel jet as it enters the cylinder. In this work, various new supersonic nozzle designs are experimentally evaluated. Experimental results for two different fuel in

Abstract:
There are over 7000 of large bore integral compressor engines distributed along the interstate and intrastate natural gas pipelines in the United States for gas compression. Methane emissions from large bore engines stem primarily from poor combustion efficiency. This study aims to improve the combustion efficiency of these engines, by reducing the amount of unburned methane that can escape through the crankcase vent and the exhaust gas emissions. Two broad approaches are taken to achieve this objective using experimental testing and computational studies: hydrogen blending and late cycle high

Abstract:
An evaluation study was conducted of the Hoerbiger/Altronic HYPERfuel� high-pressure fuel injection system. This work was performed by the EECL under contract to Hoerbiger Corporation of America. The project was funded by the Gas Technology Institute (GTI) and by the Pipeline Research Council International (PRCI). The first phase of this program consisted of start up and shakedown testing of the system. Start up was generally very straightforward and the system was operating and running the engine within a few hours of commencing start up / shakedown. The initial valve implementation tested wo
