The effects of biodiesel usage on the components of an engine
In this paper, the research results obtained on the influences of biodiesel on the components of an engine are presented. The study was carried out at the Dumlupinar University in Turkey. Biodiesel has been an alternative fuel for diesel engines since 1900s. However, the use of biodiesel has recently been increasing owing to indelible increase in petroleum price and consumption. Furthermore, the ...

Development of automotive DI diesel engine to comply with stringent emission norms
Relatively lower fuel energy cost, higher fuel conversion efficiency and ability to take higher loads are the attracting features of direct injection diesel engines. However, diesel engines are still posing the challenges to both researchers and manufacturers in terms of high soot and NOx emissions. To overcome these difficulties, small diesel engine manufacturers are resorting to either upgrade ...

Performance and emissions of a dual fuel operated diesel engine
Vegetable oil and its esters (biodiesel) are the renewable alternative fuels that can be used as a substitute for diesel in the diesel engines. The vegetable oil fuelled diesel engine results in lower efficiency and higher smoke emission. Hence in this work, an attempt has been made to use inedible and under utilised mahua oil (MO) as a substitute for diesel by fumigating liquefied petroleum gas ...

Environmental pollution from the use of alternative fuels in a four-stroke engine
This paper discusses the use of the fuels propane and butane–propane (80:20) in a four-stroke engine made to function with gasoline (petrol). The experiment covered gas emissions, emissions temperature and fuel consumption. It was observed that gas emissions were reduced compared with gasoline. The reduction for carbon monoxide emissions was greater when butane–propane was used. The same was true ...

Effect of EGR on performance and emission characteristics of diesel engine at advanced injection timing
This work attempts to reduce the smoke density of diesel engine by advancing the fuel injection timing and also the NOx emission of the engine by introducing EGR at the advanced injection timing. A single cylinder 4.4 kW air cooled, naturally aspirated, stationary diesel engine was utilised for the investigation. Engine tests were conducted at different loads at standard injection timing and ...

Effect of hydrogen enriched air on the performance and emissions of mahua oil fuelled diesel engine
Neat vegetable oils as fuels for diesel engines give rise to engine performance and durability problems due to the differences in some of the properties between vegetable oils and diesel. The objective of the present work was to improve the performance of mahua oil fuelled diesel engine using hydrogen enriched air. Mahua oil was used as the main fuel in a direct injection diesel engine and ...

Exergy evaluation of emitted waste gas and fuel consumption in food delivery process
Food delivery from restaurants and fast food shops by motorbikes is one of the major modes of its distribution. We aim to investigate the environmental impact of food delivery process by motorbikes. The environmental impact was described from the viewpoint of waste gas emission and emission exergy. A university campus was selected as the test site. We extracted the number of food delivery, ...

Case No. 501: New QXC Silencer/Converter Installed on Waukesha H24GSID 375 KW Natural Gas Engines Achieves 2007 California NOx Regs
Generating power with natural gas engines in large commercial buildings, while controlling emissions and noise from the engines requires a unique catalytic solution. Johnson Matthey’s new QXC model 3-Way converter silencer was chosen for the task. This design contains a unique catalyst element sealing system that insures against pollutant bypass. Background Equity Offices had a need to ...

Reduced Emissions for Landfill Gas Installations
The use of landfill gas as a source of renewable energy is increasing. For environmental and safety reasons, the owners of the waste storage sites have to strictly monitor and control the construction, operations, and emissions generated. Sulzer offers solutions to control these emissions within the limits given by the government. Landfill gas is similar to natural gas, but it is created by the ...
