Welcome to the EVIC Engine Web Site --- www.EVICengines.com
Camless Electronic Valve Internal Combustion Engines
  • 4 Stroke I.C. Engines with Solenoid Operated Valves.
  • Mechanically very simple - no gears, camshafts, cams or push rods.
  • Greatly reduced mechanical losses. Fewer moving parts
  • Micro computer control gives dynamic variable valve and spark timing
  • Very easy starting by holding the exhaust valve(s) open when cranking.
  • 7th generation electronics use a low cost PIC micro computers
  • "Electronic Throttle" to control speed and power and reduce pumping losses.
  • Cycle skipping and hit and miss operations to save fuel.


New, January 2011. Updated, December 2011.

The more efficient and more powerful
- 18cc Mk4A engine -
featuring linear Hall effect
- Valve Position Sensors -
for much more precise
valve control at high speeds
with the Mk7A electronics.

The McQueen EVIC - 111 Mk2

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 Rev.6 book documents the design changes and improvements made from 2001 - 2009
and includes full plans for the Mk2 and the Mk4 engines.
Several EVIC engines have been built from these plans.

3 working EVIC Engines at NAMES 2002 in Southgate, MI, USA.
