Experimental comparison of different injection timings in an HCCI engine fueled with n-heptane

International Journal of Automotive Science and Technology, 2017
One of the most effective methods to control the combustion phasing of a homogeneous charged compression ignition (HCCI) engine is injection timing. Injection timing affects the homogeneity of the mixture, start of combustion and heat release rate.

GRB 180620A: Evidence for Late-time Energy Injection [PDF]

The Astrophysical Journal, 2019
Abstract The early optical emission of gamma-ray bursts (GRBs) gives an opportunity to understand the central engine and first stages of these events. About 30% of GRBs present flares whose origin is still a subject of discussion. We present optical photometry of GRB 180620A with the COATLI telescope and RATIR instrument.

Effect of Performance by Excessive Advanced Fuel Injection Timing on Marine Diesel Engine

Applied Sciences, 2023
The injection timing of fuel in a diesel engine affects the combustion condition. Advanced fuel injection prolongs the ignition delay, positively impacting the increase in maximum combustion pressure and improving output.

Time dependent plasma injection by Io

Geophysical Research Letters, 1980
A two parameter model of time‐dependent, flux‐tube interchange diffusion is fit to the Voyager 1 plasma data obtained in the Io plasma disk. The interpretation of the parameters required to achieve the fit is that plasma injection increased suddenly and substantially (by more than an order of magnitude) at some time prior to the arrival of Voyager 1 ...
