Sentence examples for knocking intensity from inspiring English sources
Finally, such auto-ignition modes and knocking intensity for the detailed computations are summarized in the non-dimensional Bradley's diagram.
The results show that both auto-ignition mode and initial thermodynamic state can affect knocking intensity, and the modifications in knocking intensity by pressure wave disturbance are mainly through auto-ignition mode transition.
When the input power increases, the ultrasound corresponds to inertial cavitation, and the increase in the number of cavitation bubbles leads to a small amount of useful bubbles, weakening the knocking intensity [67].
In the case of the isothermal wall condition, the peak around 650 K is reduced due to the lack of a local temperature increase at the wall, demonstrating the influence of wall temperature conditions on the strength of knocking intensity.
On this basis, this study further investigates the role of pressure wave disturbance in auto-ignition mode and knocking intensity by means of detailed numerical simulations with stoichiometric H2/air mixture.
It is found that as initial temperature increases, there is a transition for the auto-ignition (AI) position from the near-wall region to the region ahead of SI flame front, resulting in distinct pressure mutation and knocking intensity.
The optimization objective is to maximize the fuel economy, under the restriction conditions of WOT torque reduction percentage, knock intensity, and exhaust temperature.
Interactive effects of the LIVC, geometrical compression ratio, spark timing and air-to-fuel ratio on the fuel economy, WOT torque, knock intensity and exhaust temperature were deeply investigated.
The octane number is determined by comparing, under standard conditions, the knock intensity of the fuel with that of blends of two reference fuels: iso-octane, which resists knocking, and heptane, which knocks readily.
With the established knock model, it is possible not only to investigate whether knock is observed with changing operating and design parameters, but also to evaluate their effects on the maximum possible knock intensity.
By considering this fact that knock is one of the important defects in the spark ignition engines, the proposed filter is applied for knock intensity measurement as a case study.
