20150326_091533-12003: Three wheeled test vehicle. 5.5hp Briggs and Stratton (B&S). Could operate as external spring pulse engine or conventional engine. Result: confirmed power pulse theory, 17% better mileage.

 

 

20150325_1647392004: 5.5hp B&S telescoping spring loaded connecting rod, pulse engine. Result: failure.

 

 

.

2015-03-24_22.15.212005: 5.5hp B&S and a Stover “piston in a piston” air spring pulse engines. Result: not the best outcome prototype engines. Near disaster for the Stover prototype when it fell off the test stand while it was running.

 

 

 

 

 

.

20150319_1424272006: B&S 5.5hp open crankcase engine, with a 4 lobe cam in place of a crankshaft; spring return. As with all my cam engines, all four strokes in one revolution. Slow 1/2 length intake stroke, normal speed 1/2 length compression stroke, quick full power stroke and normal speed full length exhaust. Result: 4.5cc/hp/min. We’re on to something.

.

pusherwheel2007: A purpose-built automobile pusher cart with a 13hp Honda engine attached to a Dodge Omni. Result: achieved 50mpg @ 53mph.

 

 

.
20150318_1649162007: A Ford piston and 4 valve overhead cam head, installed on an antique Stover engine. Result: used this engine for many tests.

 

 

.

1993 Ford Ranger2008: Purchased 80hp electric 1993 Ford Ranger from a local city to be used as test mule for X-Prize contest. Added a 24hp Honda gas engine and 10kw generator for hybrid. Result: drove back and forth to work, 54mpg equivalent.

.

20150319_1435472008: B&S 5.5hp push and pull cam engine. Result: did run, but no real test.

 

 

.

merge32009: Purchased 2000 Ford Focus, and converted into hybrid. 29hp single cylinder pulse engine, IVSD, 3 Honda electric motor/generators, 8 Honda 144 volt batteries, and a flash tube steam boiler heat recovery system feeding a two-stage steam turbine.  The car was used for the X-Prize 100mpg contest (team adiabatic).  Result: withdrew from contest as they wanted my intellectual property. Car returned approximately 75mpg highway.

 

.

20150323_1002382009: Bee hive heat conserving engine. Result: cooked itself.

 

 

 .
20150319_113033 2010: External offset-crank pulse engine. Result: good theory, but flew apart during testing.

 

 

 

 

 

 

 

 

.

13HP Honda Engine 2010: 13hp Honda pulse technology engine, 15:1 compression, 6.5hp carb. Result: went from 6.5cc/hp/min stock to 5.5cc/hp/min modified, still producing 10hp.

20150319_1127282011: 24hp Honda twin. Air injection, water injection, high compression tests. Result: nothing good to report.

 

.

.
merge22012: 13hp Honda pulse engine with a catalytic converter, exhaust heat recovery flash tube boiler, a two stage steam turbine and twin turbos. Result: very impressive complexity, gained 10% free power, nifty engine to watch run.

 

 

 

 

 

.
20150319_1101222013: Twin 32ci B&S cast-iron flathead engines (64ci) fitted to make a horizontal opposed pistons with overhead valves, offset crank to bore, common combustion chamber engine. Result: 4.4cc/hp/min. Heavy.

 

.

merge2014-2015: Twin 28ci aluminum I/C B&S engines (56ci) fitted block-to-block to create an opposed pistons, common combustion chamber, OHV engine with a piston phaser that allows for adjustable 4ci to 8ci combustion chamber size, cylinder-quenching minimizing technology, cu.in/sq.in minimizing technology x 2 (no heads, big single), and piston pulse technology. Result: best engine the company has built. Should get us into the 90mpg range.

Dodge NeonNEXT: Fitting the “twin28” and an 85hp electric motor/generator with a Curtis controller into our newest test car: a Dodge Neon.
