The nozzle is designed to atomize the fuel — to make as fine a mist as possible so that it can burn easily. The amount of fuel supplied to the engine is determined by the amount of time the fuel injector stays open. This is called the pulse width, and it is controlled by the ECU...
MegaSquirt uses all these factors to determine the fuel pulse width - longer pulse widths mean more fuel (richer), shorter pulse widths mean less fuel (leaner). To understand these, we will start with the basics: the Ideal Gas Law, the REQ_FUEL value, and the fueling equation....
How Does a Laser Pointer Work? The Basics of an Atom An atom, in the simplest model, consists of a nucleus and orbiting electrons. HSW There are only about 100 different kinds of atoms in the entire universe. Everything we see is made up of these 100 atoms in an unlimited number...
Fuel is fed axially from a feed pump (4) and a hose (the delivery hose). The meter works by sending pulses to a counter mechanism. The counter mechanism has two inter-engaged threaded spindles that detect fuel rotation through a pulse-emitting device. This pulse is then sent to an electr...
A pulse jet is not a ramjet, but they share qualities in common, including simplicity and a minimum of moving parts [sources: Encyclopaedia Britannica; Encyclopaedia Britannica; Encyclopaedia Britannica; National Museum of the USAF; van Pelt]. Ramjets: Making Mock of Mach The Lockheed SR-71A...
According to a U.S Navy study, lead acid battery life can be extended to 8-10 years using pulse charging. According to Navy scientists (the source page is missing): Excessive sulfation takes place on the plates of lead acid batteries and charging them with pulses of DC current can break ...
Apparent loss of injection pulse or fuel pump. Intermittent starting problems. Overheating ECU. What happens if my ECU is bad? If the ECU has any issues, it may throw off the timing and fuel settings of the engine, which can negatively affect performance. A faulty ECU may cause the vehicle...
Arterial pulse waveform analysis.These calculate the cardiac output from shock waves created by blood flow. Low Output If your heart doesn’t pump enough blood to supply your body and tissues, it could signalheart failure. Low output also could happen after you’ve lost too much blood, had ...
and hamstrings. They’re great for building muscle and toning your backside. You can start with bodyweight squats, but for an added challenge, hold a dumbbell or kettlebell. There are also many variations to keep things fresh, like sumo squats or pulse squats, which help target different area...
