engine head idea

On the other board, we talked of heads without the need for
pushrods
camshaft
lifters
intake
rocker arms
timing gears
timing chain
starter
ect ect
check this head idea out


order of operation
piston moves down and suction is forcing the intake valve open
fuel and air come in to the chamber
piston reaches full bottom end of stroke
intake valve closes due to no more suction
locking solenoid pluger extends on exhaust valve via electrical signal
plunger puts the pivit exhaust valve rod in a bind.
exhaust valve can not open.
piston reaches top end of compression stroke
DIS system fires off your plug
explosion happens
intake valve is forced to stay shut due to explosion/compression
exhaust valve remains locked
piston travels down to full bottom stroke
locking solenoid disengages via internal spring and signal loss
piston travels up
exhaust valve "door" opens due to piston forcing it to do so.
exhaust gas leave chamber
piston reaches full top
exhaust valve closes due to no upward presure
opposing spring forces it shut when it reaches top.
piston travels down
"passive" intake valve opens
gas/air come in
piston reaches near bottom
locking solenoid locks again,,,,process repeats.......

parts explaination
intake valve
has two  nuts on top to adjust spring reaction and valve opening distance. one adjusts while the other locks the setting in place.
removes from the bottom like normal valve

exhaust valve
the valve is actually mounted as a part of the head.  Its a doorway sort of.  the rod that passes upwards thru the head is designed like a pushrod where it seats on the valve door way.  there is a notch in the side of the rod to help stop it from opening during compression stroke via the use of the locking solenoid.  This reduced the amperage needed in our other concept relating to the other board.
the main large nut on the top threads into the head to keep the valve rod inside the head and puts tension on the opposing spring. there is a lock nut as well on the top to adjust spring reaction time as well as opening distance.
exhaust rod removes from the top.
***cant figure out a lubrication method for the area where the rod meets the exhaust valve door (designed like pushrod to lifter method). :dunno:

fuel injector
located where it normally is

spark plug
located where it normally is

spark
DIS system employed.
