“…Nagaoka et al [17] used a particle film model in 3D calculations of SI engines. Stanton et al [18,19], Bai et al [20] and AhmadiBefrui et al [21], Foucart et al [22,23], have developed liquid film models using eulerian continuous approaches. The major physical mechanisms affecting the liquid film are ( Fig.…”

“…Y s is obtained by: (19) where M f and M amb are the molecular weights of the fuel and the ambiant gas, p is the ambiant pressure and p v is the vapor pressure of the fuel at the liquid interface temperature. Following Hubbard [27], c pg , the gas specific heat, Sc, the Schmidt number and Le, the Lewis number are calculated using the thermophysical properties evaluated at the reference temperature:…”

“…Fuel injection at lower ambient temperatures adversely affects the fuel atomization, retards heating of the fuel droplets and its evaporation which make it difficulties in starting of the engine (Chris et al, 2013). Stanton et al (1998) reported that a large portion of the injected fuel during the cold start, which was not burned that adhered to the cold surfaces and made difficult to vaporize and increased the cold start combustion instability with the drop in the ambient temperatures (Stanton, 1998;Dardiotis et al, 2013). To meet the stringent emission norms particularly, with nitrogen oxides (NO x ) emissions require exhaust after treatment devices such as lean NO x traps or Selective Catalytic Reduction (SCR).…”

“…This phenomenon may enhance cylinder liner wetting, if injection occurs when the piston is down enough [15]. Considering later injection timing (close to the TDC), a large quantity of fuel reaches the piston wall and the higher kinetic energy may help to guide fuel towards the glow plug; this effect may appear depending on piston bowl shape, injection timing, etc.…”
