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....
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 ...
A gas station loyalty program is one of the best options for instantly saving money on gas. Fuel rewards programs allow you to earn cash back or points to redeem for a gift card to get free gas at the pump. Furthermore, it’s common for gas apps to offer instant savings of up to $...
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...
The European aviation sector must substantially reduce climate impacts to reach net-zero goals. This reduction, however, must not be limited to flight CO2 emissions since such a narrow focus leaves up to 80% of climate impacts unaccounted for. Based on r

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...
How to interpret the codes from the example waveforms Figure 3 - How to read fault codes The sequence begins with a long pulse, indicating the start of the code-reading sequence from the PCM. The example waveforms show codes in the 4-digit EOBD/OBDII format, but other variants of Mazda ...
The frequency of the resulting pulse train is a measure of flow rate, while the total number of pulses gives the size of the batch. While PD meters are operated by the kinetic energy of the flowing fluid, metering pumps determine the flow rate while also adding kinetic energy to the fluid...
