It helps to maintain a proper fuel-air mixture
according to the load conditions.
The fuel injection system delivers fuel or a fuel-air mixture
to the cylinders by means of pressure from a pump.
The reality is that having a 12,000-volt spark in the midst of a combustion event fired by a much higher-energy spark doesn't affect what is already happening as the fuel-air mixture
Their so-called LAG system is characterized by a small PC volume, which is fueled with a rich auxiliary fuel-air mixture
directly before the ignition event.
There was a carburetor to add fuel to the compressed air, as well as an automatic distributor to shoot the fuel-air mixture
into each cylinder in the proper firing order.
In some situations, when the throttle valve is slightly open at idle, the fuel-air mixture
may be too poor for normal engine operation.
Upon impact and explosion of the weapon's internal payload, the fuel-air mixture
is detonated, too.
The difficulties in ascertaining the exact values of the initial conditions of the fuel-air mixture
can lead to inaccuracy in model prediction and also analyses and interpretation of experimental data [3-5].
Through the intake stroke and early part of the compression stroke, the particle temperatures drop, consistent with the heat transfer to the much cooler fuel-air mixture
for an intake air temperature of 20[degrees]C.
If the pilots of the flight don't notice the issue and correct it, the EASA said that combined with an inoperative fuel tank inerting system, the failure could lead to the fuel-air mixture
in the fuel tank igniting.
"This condition, if not detected and corrected, combined with an inoperative fuel tank inerting system, could lead to an uncontrolled overheat of the hydraulic fluid, possibly resulting in ignition of the fuel-air mixture
In the cylinder there is an accelerating process of combustion of a fuel-air mixture
throughout the volume of the combustion chamber.
