Lead is currently banned from most gasoline because it is harmful to humans. While aviation gasoline still contains lead, this may change in the near future due to increased regulation in the interest of public safety. This has created a research opportunity to verify that new unleaded aviation fuels are compatible with equipment currently in use. The Cooperative Fuels Research (CFR) engine is ...

Ignition of Nanocomposite Thermites by Electric Spark and Shock Wave Report Title Nanocomposite 8Al ·MoO3 thermite particles were prepared using arrested reactive milling and ignited using two experimental techniques. In spark ignition, a monolayer of powder was placed on a conductive substrate and heated in air by a pulsed electrostatic discharge. In shock ignition, an individual particle was ...

Towards a Stronger Simulation Support for Engine Control Design: a Methodological Point of View — Thanks to a specific crank angle degree modelling approach and to an accurate simulator calibration, it is nowadays possible to build a complete simulator which allows the control engineer to access to numerous engine variables, especially non measurable values, and to perform tests over a wide ran...

The use of nonequilibrium plasma generated by nanosecond discharges to ignite fuel/air mixtures, known as transient plasma ignition (TPI), has been shown to effectively reduce ignition delay and improve engine performance relative to spark ignition for combustion engines. While this method is potentially useful for many engine applications, at present the underlying physics are poorly understoo...

This study deals with artificial neural network (ANN) modeling of a spark ignition engine to predict engine thermal balance. To acquire data for training and testing of ANN, a fourcylinder, four-stroke test engine was fuelled with ethanol-gasoline blended fuels with various percentages of ethanol and operated at different engine speeds and loads. The performance of the ANN was validated by comp...

The effects of hydrogen-enriched biogas on combustion and emissions a dual-fuel spark-ignition engine with different hydrogen concentration ratios were studied numerically. A 1-cylinder spark ignition was used to perform numerical simulation. To reveal the influence compression gaseous engine, crankshaft modified generate 8.5, 9.0, 9.4, 10.0, 10.4. contained 60 40% methane (CH4) carbon dioxide ...

An experimental study is carried out to investigate engine performance parameters and methods of reducing emissions from spark ignition engine. Fuel efficiency is one of the major concerns for the users, the designers and the manufacturers of internal combustion (IC) engines, The effect of increasing the temperature of cylinder liner has the advantage of reducing the specific fuel consumption b...

In this paper we start with Meyer-Ter-Vehn isobaric fusion model and try to reconstruct all equations by introducing a dimensionless variable ?i=ri/Rm. Then we investigate the proper sets of spark confinement parameter and temperature {Hs,Ts} which satisfy ignition conditions of spark ignition in deuterium-tritium (DT) equimolar mixture in terms of isentrope parameter, ?, implosion velocity, Ui...

Combustion analysis has been conducted on a small two-stroke glow ignition engine, which has similar combustion characteristics to homogeneous charge compression ignition (HCCI) engines. Difficulties such as unknown ignition timing and the polytropic index have been addressed by combining both heat release and mass fraction burn analyses. Results for all operating conditions have shown good cor...
