Abstract This work models the impact of direct water injection on combustion process in a spark ignition engine. It uses two-zone kinetic model coupled with detailed chemistry to highlight thermodynamic and chemical-kinetic interactions between gasoline injection. The modelling results agree closely measurements from highly boosted, study first proposes an approach mass fraction burned (MFB) pr...

Thermal processing (torrefaction, pyrolysis, and gasification), as a technology can provide environmentally friendly use of plastic waste. However, it faces problem with respect to its by-products. Pyrolysis oil obtained using this is seen substance that extremely harmful for living creatures needs be neutralized. Due relatively high calorific value, considered potential fuel internal combustio...

Abnormal combustion occurrences in compression ignition engines are one of the main causes of engine failures, which severely affect the continuity of transportation operations. The detection of these occurrences may help to take measures to minimize the engine failures and increase engine life. In this work, we implement a machine learning system for abnormal combustion detection system in a s...

This paper describes the use of a neural network in a technique suitable for diagnostic or condition monitoring applications in a spark-ignition engine. The method involves the use of voltage and current variations at the spark plug under normal running conditions, together with neural network analysis. Waveforms produced under test using this technique contain information relating to the adjus...

This article makes the argument that compression ignition combustion processes that are “flameless” with volumetric energy release, described as Low Temperature Combustion (LTC), are a thermodynamic pathway to maximizing the efficiency of reciprocating piston, internal combustion engines. The argument is built from the foundation of determining the maximum theoretical efficiency for an IC Engin...

Fuel efficient Homogeneous Charge Compression Ignition (HCCI) engine combustion phasing predictions must contend with non-linear chemistry, non-linear physics, period doubling bifurcation(s), turbulent mixing, combustion deposits, model parameters that can drift day-to-day, and air-fuel mixture state information that cannot typically be resolved on a cycle-to-cycle basis, especially during tran...

Laser ignition has been discussed widely as a potentially superior ignition source for technical appliances such as internal combustion engines. Ignition strongly affects overall combustion, and its early stages in particular have strong implications on subsequent pollutant formation, flame quenching, and extinction. Our research here is devoted to the experimental investigation of the early st...

One of the most important parameter for spark ignition engines is volumetric efficiency, as it directly influences specific power output. Several definitions of this parameter are studied from a theoretical point of view, taking into consideration the use of alternative fuels. The influence of using gasoline-bioethanol blends is investigated, as well as the effect of fuelling spark ignition eng...
