PACIFIER V-4,     4 Cylinder, 4 cycle, 2004

  5/11/2004

The Pacifier V-4 is a 4 cylinder, 90 degree gas engine with 5/8" bore. It has my latest carburetor, the Minimix and my Hall Effect distributor. The ignition coil is the Exciter coil that I designed for Mike Neal and is available from him. The Pacifier has been cranked and ran, it idles and sounds well. it has a roller clutch and water pump. Water circulates around the cast iron cylinder liners. The crankshaft and camshaft are supported by ball bearings. The crankshaft has oil seals.
 
The Pacifier is a nice engine to exhibit as the outside appearance looks great, the block is short and one can see the rockers and push rods working. It uses 10W30 oil and the fuel is regular gasoline with 10 % WD-40.
 
Ken Hurst and the BAEM club will attempt to make the castings and drawings (3/4" bore) available to all builders, any profit will go to the BAEM club.
 
The Pacifier is not very difficult to build for someone with some engine building experience.
 

 

THE ENGINE IS THE PACIFIER V-4 THAT I AM DESIGNING/BUILDING, IT IS RUNNING AND I AM PUTTING THE FINISHING TOUCHES ON IT. I HOPE TO    RE-PATTERN, CAST AND MAKE IT AVAILABLE AS A 3/4" BORE. A WORK IN PROGRESS.
 

 

FIRST POP FOR THE PACIFIER WAS YESTERDAY. THE HALL EFFECT DISTRIBUTOR AND THE MINIMIX CARBURETOR PERFORMED PERFECTLY. I NOW HAVE 1.5 MINUTES OF RUNNING TIME ON IT. NO RADIATOR, WATER PUMP, EXHAUST PIPES, MOUNTS BUT IT RUNS.

 

 

 

THE CARBURETOR IS THE MINIMIX, DESIGNED FOR 5/8" TO 3/4" BORE ENGINES. 13 GENERATIONS OF DESIGN CHANGES TO GET IT SMALL ENOUGH SO AS NOT TO OVERWHELM A SMALL ENGINE. IT IS EASY TO BUILD AND HAS ONLY 5 PARTS, INCLUDING THE THROTTLE LEAVER. A MEASURED DRAWING IS FREE TO BUILDERS IF THEY PAY THE POSTAGE.
 

THE DISTRIBUTOR IS A HALL EFFECT DISTRIBUTOR FOR UP TO EIGHT CYLINDER ENGINES, THE ALUMINUM BODY IS 1" OD. A UNIQUE DESIGN THAT PERFORMS WELL AT HIGH SPEED. A MEASURED DRAWING IS FREE TO BUILDERS THAT PAY THE POSTAGE.
