    PWM intensifying

    The valve works on 24V and has the function to control an amount of flow, so it is indeed proportional. Sadly I do not have a datasheet of the coil, it's used very often on high pressure pumps of Bosch. So I need to search for a drive instead of only using a transistor? Thanks

    PWM intensifying

    Hello everyone, I have to control a solenoïd valve proportionally using a 166Hz PWM signal. The resistance of the coil is 2,5-4 ohm. If i'd be using a pure DC signal I'd have around 8 amps of power. However this is an oscillating signal. Since a coil resists changes in current, the effective...

    Automotive Common rail high pressure pump

    Well, I heard of 2 systems: One where a pressure control valve is mounted on the rail to open and close the return line. Another where an Mprop opens and closes the inlet of the high pressure pump. I make use of the second system. If the Mprop is fully closed, pressure in the rail should drop...

    Automotive Common rail high pressure pump

    Hello everyone, I have a question about a common rail high pressure pump. Most common rail pumps make use of a pressure control-valve which controls the amount of fuel that goes to the plunger. This way it is possible to control how much fuel goes to the rail, so it controls the pressure...
