Next big thing i see isthe solenoid is either open or closed. Much goes into cooling the valve train via engine oil. The biggest problem with the current cam / valve design is heat. My two cents - yes a solenoid could open a valve on an ICE. Then decide if you really want to do this. Notice how much effort is going into ways to reduce the electrical energy needed to actuate valves. The laminations were 0.014" thick steel of a special magnetic alloy.Īt this point, take a break, and search electromagnetic valve actuator engine.
The knife cylinders are 10" apart on center, and the electromagnet stack was about 4" thick. The drawings in US Patent #6,389,941 of this electromagnet are only approximately to scale, but you can get an idea of the magnet size from the drawing. Peak current was 50 amps, and it needed about 170 volts to meet the di/dt requirements. The duty cycle was approximately on for 9 msec, then off for 9 msec. To give an idea of what the electromagnet will look like, I once designed an electromagnet that pulled 1600 lbs force through a 1/8" air gap, and turned on and off 55 times per second. The magnetic air gap is 1.0" because the field goes from the electromagnet, through the air, through the valve actuator, then back through the air to the electromagnet. Now you need to design the electromagnets for 1.5 Tesla through a 0.5" physical gap. Not shown is a position feedback device so the controller knows the valve position. The other pulls the valve closed and decelerates the valve when opening. One pulls the valve open and decelerates the valve when closing. Valve can be mounted in any position.This design has two electromagnets.
Series 830 solenoid valve with manual override switch, valve can be opened manually when no electricity supply. Valve stays close when the coil is de-energized, and it opens when energized. This solenoid valve has one inlet and one outlet port. Valtorc USA's series 830 2-way normally closed electric solenoid process valve is to control On/Off of air, inert gas, liquid, and water.
