What kind of base does air fuel system use?
Designed to suit the operational environment, a heavy duty and fully galvanised steel base, with or without sheltering, is manufactured to ergonomically house all the necessary equipment required, from filters to meters to hose reel and hose.
What kind of fuel system does a small aircraft have?
Small single-engine aircraft fuel systems vary depending on factors, such as tank location and method of metering fuel to the engine. A high-wing aircraft fuel system can be designed differently from one on a low-wing aircraft. An aircraft engine with a carburetor has a different fuel system than one with fuel injection.
Which is the best air / fuel ratio for fuel injection?
Different fuels have different weights and work best at different air/fuel ratios. The stoichiometric point is the AFR where all of the oxygen in the air burns with all of the fuel. At the stoichiometric ratio, only burnt exhaust byproducts are in the exhaust gas mix with no excess, unconsumed oxygen or fuel.
What to do when your fuel line is bleeding air?
Open the bleed plug on the filter closest to the fuel tank. 6. Open fuel supply valve so that the fuel is available to the filter and pump. 7. Most all equipment has a hand priming pump lever to pump fuel through the system and replace trapped air. (Check operator’s manual.) Pump several times until full
What kind of fuel does a MFI system use?
MFI systems with alcohol or nitro fuels, combined with forced induction can provide extremely high power levels. PSI screw-blown 500 cubic-inch V8 engines on methanol report power levels over 4,000 horsepower, and methanol has other benefits.
When do MFI fuel bypass jets come on?
MFI fuel bypass jets control the fuel mixture to the engine. These jets divert a certain amount of fuel away from the engine and back to the fuel tank, which is useful for controlling the overall fuel flow to the engine. Additionally, high-speed bypass jets come on when the engine reaches a certain engine speed.
How is the air and fuel ratio maintained?
Maintaining the air/fuel ratio by changing the main bypass is a simple method that leaves the rest of the engine nozzles untouched. For an increased level of air/fuel ratio adjustment at higher engine speeds, an added high speed bypass jet brings more control.
