Improving supply chain responsiveness for diesel engine remanufacturing
… in order-to-shipment lead-time of remanufactured diesel engines can dramatically decrease the amount of finished goods inventory that Caterpillar needs to carry in order to meet its delivery commitments to Cat dealers around the globe. This project was launched to devise ways to hold less finished …

Waste heat recovery from a high temperature diesel engine
… economy and emissions from internal combustion engines (ICEs) are driving innovation in engine efficiency. Though incremental efficiency gains have been achieved, most combustion engines are still only 30-40% efficient at best, with most of the remaining fuel energy being rejected to the …

Dual fuel conversion of a direct-injection diesel engine
Dual fuel pilot-injected diesel natural gas engines offer significant potential to reduce oxides of nitrogen (NOx) and particulate matter (PK emissions while maintaining diesel-like efficiency. A 1994 Navistar T444E turbocharger V-8 diesel engine was converted to dual fuel diesel and compressed …

Performance and emission characteristics of a gas-diesel engine
… injection of natural gas with liquid pilot-diesel fuel (ie. gas-diesel operation) was investigated in a single-cylinder, two-stroke compression-ignition engine with a poppet-valve gas-diesel injector. The investigated injector geometries and engine operating parameters included: fuel …

Emission characteristic of small diesel engine fuelled by preheat biodiesel
… emissions and performance parameters of the engine. The higher viscosity has effect on combustion and proper mixing of fuel with air in the combustion chamber. The aim of this present research was to investigate the effects of preheated biodiesel derived from Waste Cooking Oil and Jatropha …

Stability Analysis of a Turbocharger for Marine Diesel Engine Service
… turbochargers, such as those found in marine diesel propulsion engines where the rotor alone often exceeds forty pounds, require careful consideration regarding stability as well as load support during the bearing selection process. Logarithmic Decrement is the primary consideration for rotor …

Heat of combustion of algae for use in a diesel engine
… Although algae can be used to create biodiesel, methane, ethanol, and hydrogen these technologies are complicated and are still in the demonstration phases. This study explores if algae could be used directly as an alternative fuel in a diesel engine to create electricity. In this study a …

In-Cylinder Soot Oxidation in an Optically Accessible Automotive Diesel Engine
The problematic soot emission of diesel engines is the net result of the competing in-cylinder formation and oxidation processes. Previous studies primarily focused on the soot formation, whereas the oxidation of soot particles remains an unexplored and least studied topic. To bridge this gap, this …

The potential use of bio-ultracarbofluids in a standard diesel engine
The replacement of diesel fuel by ultra-carbofluids was perceived to offer the potential to decrease the emissions of environmental pollutants such as carbon dioxide, carbon monoxide, hydrocarbons (HC's) and smoke. Such ultracarbofluids consist of a suspension of coal in fuel oil and water …

After treatment and turbocharger effects on emissions of a diesel engine
… a turbocharger on emissions of a single cylinder diesel engine. The study measured the concentration of CO, CO2, HC, NO, NO2, and NOx. Tests on the engine were performed at different engine loads and engine speeds. The engine power ranged from 0 to 9 HP, and the engine speed ranged from 1500 to …

Experimental and computational study of soot formation under diesel engine conditions
Past research has shown that during diesel combustion, soot is formed in local premixed fuel-rich regions. This project focuses on the fundamentals soot formation under fuel-rich conditions similar to those in diesel engine operation. Since these conditions cannot be easily reproduced in typical …

Effects of artificial neural networks characterization on prediction of diesel engine emissions
More than a century after its invention, diesel remains the fuel of choice for buses and freight trucks. Diesel exhaust contains three gases that are regulated by the United States Environmental Protection Agency (EPA), as well as particulate matter (PM). There is a societal need both to lower …
