The amount of electrical current that the charging system provides to your vehicle's battery is monitored by either a voltmeter, which measures the voltage in the charging system, or an ammeter, which measures amperage leaving the battery. When the battery is using too much of its own juice ...
aTHRUST PLATE, CRANKSHAFT 推力板,曲轴[translate] a写一手漂亮的字 Writes an attractive character[translate] a风和水不同,它来去无踪,科学家很难准确的把握,所以运用起来会有很多的浪费。 The wind and the water are different, it round trip does not have the trace, the scientist is very difficult...
Photo: 1) A typical silicon Hall-effect sensor. It looks very much like a transistor—hardly surprising since it's made in a similar way. Photo by explainthatstuff.com. 2) A Hall-effect probe used by NASA in the mid-1960s. Photo by courtesy of NASA Glenn Research Center (NASA-GRC)...
The connecting rod connects the piston to the crankshaft. It can rotate at both ends so that its angle can change as the piston moves and the crankshaft rotates. Crankshaft The crankshaft turns the piston's up-and-down motion into circular motion just like a crank on a jack-in-the-box d...
Based on how much the frequency changes, a radar gun can calculate how quickly a car is moving toward it or away from it. If the radar gun is used inside a moving police car, its own movement must also be factored in. For example, if the police car is going 50 miles per hour and...
Moreover, perching is more difficult for large (> 1 m wingspan) ornithopters. Indeed, appendage strength scales with the cross-sectional area \({L}^{2}\), but the kinetic energy of the flying vehicle scales up much more strongly with \({L}^{3}{v}^{2}\)10. This implies that ...
How to Fix: Clean or replace the MAF sensor. #2 – Oxygen Sensor Malfunction An oxygen sensor (aka O2 sensor) is device whose function is to monitor the exhaust emissions of the vehicle so that it can analyze the air-fuel ratio going through the engine of that vehicle. To make a long...
Keeping an eye on MAP sensor inputs is a good way to ensure your engine works efficiently and to spot issues early. Changes in these readings might affect how well your engine performs and how much fuel it uses. They can also cause the check engine light to turn on. ...
The static force applied to an object is called reaction or stationary torque. For example, when you put a lug wrench onto a bolt and then attempt to tighten it, you are applying reaction torque to it. Even if the bolt doesn’t turn much or at all, the reaction torque is still presen...
Before a vehicle can drive, the engine draws a mixture of fuel and air into the combustion chamber, which burns to turn the crankshaft and other engine components so the vehicle can move. The spark plugs ignite the fuel/air mixture by creating a spark that causes the mixture to explode, ...
