Automotive Technology 썸네일형 리스트형 Clutch Assembly Clutch Assembly The clutch assembly is located between engine and manual transmission and it provides a mechanical coupling between the engine’s flywheel and input shaft of the transmission. To operate the clutch the driver should push the clutch pedal, then the mechanical linkage transfers the forces to the clutch assembly. Normally a clutch is always engaged (if no power is applied in the peda.. 더보기 ABS/TCS/VDC ABS (Anti Block System) was originally invented for airplane, because keeping weight balance in airplane is very hard because of long wing span if skidding happens at the tires during landing or taxing. Now, most of the vehicles are equipped with this ABS device and this helps quite a lot for safe driving. Slip Ratio When drivers pushed brake pedal, the pedal forces are converted into hydraulic .. 더보기 Brake System Brake Systems If I want to stop a running vehicle, what can I do ? The easiest way is cutting power flow from engine to driving wheels, then the vehicle will surely stop in a while, not so effective and quick enough as I want. Therefore, the quickest way to stop a running vehicle is to grab wheel not to be able to turn and let the road surface grip the tire surface, then we can reduce the speed .. 더보기 Turbocharger Turbocharger Turbochargers are used to increase engine performance by compressing intake air before it enters the engine combustion chamber. Turbochargers are air pumps driven by the engine’s exhaust gas stream. The heat and pressure of the exhaust gases spin the turbine blades of the pump. In general, piston inside a reciprocating engine moves up and down to intake fresh air and to exhaust gas... 더보기 Electronic Control (2) Electronic Control (2) Normally the control system consists of sensor parts which supply the information of moving parts of a vehicle or engine, controller part which processes the signals from sensors and make a proper decision based on the control logic inside of the control program and the actuator part which really does proper actions and generates a necessary movement of a vehicle. Sensors .. 더보기 Electronic Control (1) Electronic Control (1) Together with big technical advance in electronic industry, every side of our life is also being equipped with electronic devices and controllers, and our car is not an exception of this trend. The value of electronic part in our car is getting bigger every year, if electronic vehicle comes to our daily life the automotive industry can be categorized as a part of electroni.. 더보기 Spark and Ignition (3) Spark and Ignition (3) The power plant of this high voltage is “Ignition coil” of the system. Normally the ignition coil is covered by engine cover, therefore, you cannot easily see the coil. The ignition coil is small version of voltage transformer which you can find easily on the street to convert electric voltage which comes from power plant. The primary coil has windings of 200 or 300 times .. 더보기 Spark and Ignition (2) Spark and Ignition (2) Imagine a electric wire with 220 Volt electricity flowing it. Now, assume you cut it some point of the wire and keep the gap around 1 mm, then of course the current stops to flow and connected electric devices stop working. The reason that the current stops is the electric resistance of air is much higher than those of copper wire. Then how can we overcome this resistance .. 더보기 이전 1 2 3 4 다음
