Then, depending on the trouble code, the sensor signal must be tested with a scan tool. For example, see this chart of the air-fuel ratio sensor signal on a scan tool: when the engine is revved, the signal jumps to "rich", then as the RPM drops and the fuel is cut off, the sen...
ABS sensor The function of the ABS sensor is to measure the rotational speed of the wheel. There are four ABS sensors in a car; one at each wheel. n technical literature the ABS sensor is known as Wheel Speed Sensor or WSS.Air fuel ratio sensor The air-fuel ratio sensor measures the ...
How the Alcosensor III or IV Works Modern fuel-cell technology (which may power our cars and even our houses some day) has been applied to breath-alcohol detectors. Devices like the Alcosensor III and IV use fuel cell sensors. The fuel cell has two platinum electrodes with a po...
Driving on air: how a fuel cell worksDescribes the mechanism involved in the use of fuel cells in automotive vehicles. Development of the proton-exchange-membrane fuel cell; Principle of fuel cells; Parts of a fuel ...
Even if you’re an experienced runner, you may still need to hike some of the longest and steepest hills. Running on trails can take much longer than expected, so it’s wise to run by time at first to gain a sense of your trail pacing. 6. Stay safe Running off the road can be ...
The average age of aircraft in an airlines’ fleet provides a good proxy for how fuel efficient the aircraft themselves are. The key metric which is harder to come by, however, is the average fuel used per passenger kilometre on an airline basis. Except for the US Department of Transport,...
It can take off, ascend and turn much more quickly than an ordinary plane, which has much more weight per square foot of wing space. An F-15's high thrust-to-weight ratio and low wing loading let it shoot off the ground at a sharp angle. Photo courtesy U.S. Air Force Mechanical...
It uses an engine’s exhaust gas to drive the turbine wheel up to 350,000 RPM. The turbine wheel then drives the compressor wheel through a shaft. The compressor wheel provides compressed air to the engine, and this compressed-air makes the fuel burn more efficiently for greater power and ...
Mass Air flow Sensor (MAF). The Mass Air Flow sensor (MAF) is one of the key components of an electronic fuel injection system in your car. It is installed between the air filter and the intake manifold of the engine. See the diagram. The mass air flow sensor measures the amount of ...
The short run is an economic concept stating that, within a certain period in the future, at least one input is fixed while others are variable. It expresses the idea that an economy behaves differently depending on the length of time it has to react to certain stimuli. The short run does...
