A Study on the Behavior of a Fuel Droplet Injected into the Combustion Chamber of a Diesel Engine 670468

In this study, the burning rate, burning lifetime, and flight distance of a fuel droplet injected into the combustion chamber were formulated, taking into consideration the effects of high air temperature and pressure, and of droplet relative velocity.
It was confirmed by the experiment conducted that these formulas are valid, at least for a droplet in the tip of a puff of spray. They should provide strong clues to the theoretical determination of the minimum cylinder diameter suitable for small-size, direct injection diesel engines.
