“…The thermal mechanism dominates in high temperature combustion over a fairly wide range of equivalence ratios, while the Fennimore mechanism is important in rich combustion. For the features of the system and high temperature chamber combustion the NO x formation was modeled using the Zeldovich mechanism [4,10]. This mechanism consists of three reversible chain reactions: As the mole balance is applied during combustion cycle we have a closed system, and only the term of reaction and accumulation are take into account.…”

A mathematical model of emissions was developed in a Twingo D7F engine. The effects of variations in compression ratio, fuel/air equivalence ratio, spark advanced and combustion duration under pollutant emissions were studied. Analysis and data collection were performed in an engine bank using a data acquisition system integrated to an Interactive Engineering Environment. A control strategy was implemented to guarantee emissions reduction.

“…where θ is the crank angle, θ0 is the angle where the start of combustion occurs, θ is the total combustion duration and α and m are adjustable parameters. Actual mass fraction burned curves was fitted with α = 4.6 and m = 2 [16]. The mass fraction that remains unburned is given by (1 − x b ).…”

“…Here K u and K b are the heat transfer coefficients for burned and unburned zone and depend of the Reynolds number and the thermal conductivity of each zone. h R is the radiation transfer coefficient, A u and A b are the areas of each zone and T w is the transfer wall temperature which is taken as 420 K [16].The heat transfer for compression and expansion could be calculated with an easier expression…”

A mathematical and numerical model of flow and combustion process for spark ignition engines is developed using the principles of the first and second law of thermodynamic. Availability (exergy) analysis is applied to cylinder of a spark ignition engine during the combustion process using a two-zone combustion model. Special attention is given to identification and quantification of irreversibility of combustion process and energy available basing on the isooctane fuel explosion. To predict emissions generation (greenhouse gases) a skeletal mechanism including 32 species and 61 reactions was developed and tested for different engine operations and exergy destructions.

In the present investigation, a single-cylinder, four-stroke cycle, TD43 engine has been used to evaluate the first and second laws of thermodynamics terms. To this aim, the first law analysis is done by using a thermo-kinetic model. The results show a good agreement with the experimental data. Also for the second law analysis, a developed in house computational code is applied. Behaviors of the results have a good accordance with the literature. The result show that an increase in the inlet charge temperature causes the maximum pressure, indicated work availability and entropy generation per cycle be reduced and the in-cylinder temperature, heat loss availability and total availability be increased. Also the results show that an increase in the engine speed causes the total availability be increased and the heat loss availability be decreased. When the engine speed increases, reduction in the duration of cycle evolution causes the reduction of heat transfer
