The McQueen EVIC - 111
Mechanically
very simple camless engines.
· No gears, camshaft,
cams, push rods or rocker arms.
· Greatly reduced mechanical losses. Fewer moving parts.
· Reduced pumping losses when controlled by the "Electronic
Throttle".
Micro computer control
of the valve & ignition timing.
· Electronics
driving solenoids allow complete freedom of valve control.
· These engines have dynamic variation in valve timing.
· Cycle skipping & hit and miss operations to save fuel.
· Very easy starting by holding the exhaust(s) valve open when cranking.
· Dynamically controlled spark advance.
· Simple and low cost electronics; a US$3.00 PIC16C505 micro ran the 1st
engine.
· 4th generation electronics use a US$5.00 PIC16F628 and a US$2.00
PIC12C508.
· The "Electronic Throttle" function reduces pumping losses and saves
fuel.
The "Electronic
Throttle" demonstrates:
· That the
intake and exhaust valve timing can be changed to control the engine's speed
and power.
· That a speed range of 1,800 to 10,000+ RPM is achievable without manifold
throttling.
· That the stated performance advantages that can be achieved.
· That this technology can be applied to low cost easily built IC engines.
Plans for the EVIC -111
Mk1 engine were published in Strictly I.C. magazine beginning with Vol. 14 N0.
82
August/September, 2001 and ending with Vol. 14 No. 84 December, 2001/January,
2002. The expanded
EVIC -111 Mk1 book documents the design changes and improvements made
from 2001 - 2003 including
the "Electronic Throttle" function that eliminates the throttle
barrel used on the original carburetor.
Several EVIC engines have been built from these plans.
