To carry out the investigation, a cylinder pressure model was developed based on the position of the crankshaft, engine load, engine speed, and fuel injection time. This model takes into account the maximum number of parameters involved. The accuracy of the model was verified by experimental results. The average error of the cylinder pressure, the average radical of the square of the error of t...

Methanol is a widely used engine fuel, blend component, and additive. However, no systematic auto-ignition data or laminar flame speed measurements are available for kinetic studies of the effect methanol as blending additive component. In this work, both ignition delay times speeds pure methanol, n-heptane their blends at various ratios were measured engine-relevant conditions. Results show th...

One of the most widely used way to improve low-temperature properties diesel fuels is use additives. However, a variety additives and effect susceptibility make it difficult select additive for particular composition fuel operating conditions. The laws interaction between functional groups hydrocarbons fraction have not been investigated yet. article discusses influence fractional, group struct...

Hybrid rocket engine (HRE) performance is dependent on fuel/oxidizer selection and fuel grain geometry. A literature review was performed to identify key trends findings related the application of additive manufacturing (AM) systems for HREs. The effects complex combustion port geometries, embedded structures, end-burning systems, along with use metallic additives, turbulators, diaphragms, gel-...

The paper presents the combustion profile of selected fuels as a result thermogravimetric analysis. main purpose this study was to investigate mixture different types fuel and influence use additive on process profile. As additive, halloysite used profiles. It confirmed that parameters such ignition temperature, burnout maximum peak temperature correlated accordingly with combustibility indices...

O R G wide range of approaches have been undertaken to determine how to reduce emissions from automotive engines. in a previous TLT article, the development of the homogeneous charge compression ignition (hCCi) engine was discussed. When used in place of a conventional gasoline engine, an hCCi engine can produce a 1...

The demand for cleaner, more efficient, and durable sources of electricity is driving research into small-scale power generation. Micro gas turbines are especially suitable by virtue their high density reliability, but a major drawback poor overall efficiency due to increasing parasitic energy losses relative net output as size decreases. Additive manufacturing offers design freedoms that could...

• Quantitatively studied K-Capture by kaolin/coal fly ash at dust-firing conditions. K-capture reaction biomass combustion and K-salt feeding conditions was compared. Deposit probe inserted into reactor lively monitored deposit formation. Deposition propensity quantitatively with without additive addition. The deposition behavior when firing different (pulverized wheat straw, wood, bark, leaves...
