NO x emission model of turbofan engine

During last decade a lot of investigations also focused on the evaluation of aircraft engine impact on local and regional air quality in the vicinity of the airport. The emission inventory of aircraft engines are usually calculated on the basis of certificated emission indexes, which is provided by the engine manufacturer and reported in the database of ICAO. The certificated emission indices ...

Putting the Lid on Emissions - Food Engineering case study

While the aroma of a cooked steak may be enticing to some, residents near a cooked-meat facility did not appreciate it. Polarized Meat Company of Dunmore, PA produces high-quality meat products designed to reduce preparation time at restaurants. Certain products are preformed and pre-cooked, often with grill marks added to enhance the products' visual appeal and flavor. Both the incoming meat ...

The emission characteristics of a compression ignition engine operating on castor oil methyl ester

Diesel vehicles are a major form of transportation, especially in developing countries. Recent concerns over the environment, increasing fuel prices and the scarcity of its supply have promoted interest in the development of alternative sources of petroleum fuels. In this investigation, castor oil methyl ester was prepared by transesterification using potassium hydroxide (KOH) as a catalyst and ...

Study of the performance and exhaust emissions of a spark-ignited engine operating on syngas fuel

To resolve the problem of depletion of petroleum based liquid fuels, various solutions have been proposed. One of them is the use of gaseous fuels that are generated from the gasification of woods, namely syngas or wood-gas fuels, as full supplement fuels in spark ignition internal combustion (IC) engines. This fuel consists of nearly 40% combustible gases, mainly hydrogen and carbon monoxide ...

Emission Testing of Engines to be Installed in Non-Road Mobile Machinery

The European Commission has founded a project on emission testing – 'Emission Testing of Engines to be installed in Non-Road Mobile Machinery'. The project was undertaken by Abgasprüfstelle Berlin-Adlershof GmbH in Germany. The work is a part of emission inventory of spark-ignition engines to be used as a basis for a future amendment of the Directive 97/68/EC. The inventory covers seven different ...

Characterising emissions from private passenger vehicles using engine operating patterns

A method to simulate emissions factors using frequency distribution plots of engine speed and engine load is proposed. The distribution plots and corresponding emissions factors were developed from speed time series' of real-world driving cycles and physical properties of a range of private passenger vehicles tested at the EMPA. Emissions factors were estimated for a set of simultaneously ...

Performance and emission characteristics of CI engine, fuelled with diesel and oxygenated fuel blends

Vegetable oils are a potential alternative towards partial or total substitution of diesel fuels. In this study, we used ethanol as the solvent, and a bio fuel enhancer as additive to explore the possible use of higher percentages of biodiesel in an unmodified diesel engine. Biodiesel was produced from cashew nut shell liquid (CNSL) by pyrolysis process. A mixture containing 80% (by volume) of ...

Performance and emission characteristics of a DI compression ignition engine operated on PODL biofuel

This paper presents the results of investigations carried out both numerically with the CFD code CONVERGE and experimentally on a single-cylinder, four stroke, direct-injection, CI engine. The tests are performed with neat diesel, neat palm oil (PO) and different blends of PO and the D-limonen solvent (PODL), like 10%, 15% and 20% by mass of D-limonen in PO (PODL10, PODL15 and PODL20). Engine ...

Exergy analysis of combustion characteristics and NOx emissions of a dual–fuel engine

The combustion characteristics and NOx emissions of compression ignition engines working on a dual fuel mode are investigated numerically and their exergetic efficiencies are determined. The model has been validated with available experimental results. The simulation results show that dual fuel engine combustion and trend of NOx ...

Engine Testing

Engine testing involves measurement of rotating speed and torque of the engine by applying load controlled by a dynamometer connected to its output shaft. HORIBA has developed various types of dynamometer for the purpose of engine testing. They are mainly classified into two types; one is absorbing only dynamometer such as hydraulic dynamometers and eddy-current dynamometers, the other is ...

Forklift Emissions Analyzers

Forklifts are commonly used in warehouses of various size and capacity for the movement and shipping of goods; however, the unoptimized engines can produce excess quantities of silent and deadly CO gas that can risk the health and safety of the workers. When forklifts are brought in for service usually the CO gas isn't measured. If the CO gas isn't measured and the engine properly optimized then ...

Emissions reduction with Diesel blending

Diesel technologies are develops by huge rates. Modification of cars with diesel engines make a half of the new cars sold in Europe. The black smoke, noisy engine operation and unpleasant smell remained far in the past. Today diesel engines present not only profitability, but also high capacity and worthy dynamic characteristics. Quality of fuel also is changed. The modern diesel blending has ...

A constant eye on emissions

Due to increasingly rigorous requirements for regulatory and permit compliance, organisations are seeking more from all compliance support systems. The ability to expand systems to encompass new, or migrate existing, regulatory calculations used to monitor environmental performance is vital. Planning strategically for a scalable and sustainable system has been shown to reduce overall compliance ...

An end to the problem of particle emissions

Austrian biomass heating systems guarantee an 80% cut in emissions. Recent studies have shown that these modern domestic boilers offer a significant reduction in particles, emitting fewer contaminating agents than previous generation boilers and wood stoves – with more than 100mg / ml of particles. The future will be based on new biomass combustion technology which cuts dust emissions from ...
