Revolutionary New Rotary Engine
A revolutionary rotary-style engine punches out 580 hp and 2,538 ft./lbs. of torque at only 1,200 rpm's. Yet, it weighs just 300 lbs. and takes up less than 2 cu. ft. of space. This multi-fuel, internal combustion engine from Vengeance Power, Inc. can run on practically any fuel or no fuel at all. The design allows on-the-go switching from internal combustion to compressed air to steam pressure-powered rotation.
"The actual mechanics are perfected, and now we are perfecting the seals," explains
Jesse Laba, Vengeance Power. "It will find a place first in stationary and portable power generation, even powering large scale standby generators, and then in transportation."
The first scale model was shown at the Society of Automotive Engineers (SAE) Congress in April of 2009. The first working prototype will be fired up at this year's SAE Congress.
"We had to do some seal redesign from last year's model," explains Laba. "After this year's Congress, we will begin dyno testing to obtain certification for power, emissions, efficiency and durability. The next step is using it in test vehicles and platforms."
If all works according to plan, Laba and his partners in design, Tony Sleiman and Andre Laba, expect the engine to be in production within a year and a half.
The Vengeance engine is a true rotary engine, a significantly improved version of the decades-old Wankel Rotary. The combustion chambers are formed by 8 vanes that slide in and out on two sets of offset roller bearings. The vanes follow the nearly oval-shaped engine block, moving in and out to drive the central shaft. The chamber shape allows gasses to expand more slowly. The power is transmitted directly to drive shaft rotation with 8 power impulses per revolution of the engine for a smooth running engine without vibrations.
The use of roller bearings instead of sliding bearings and the elimination of pistons vastly reduces energy waste and the need for lubrication compared to traditional engines. In addition to the pistons, crankshaft, connecting rods and valve train are also eliminated.
The intake chamber is separate from the combustion chamber, allowing higher temperatures. No valves mean no restrictions in airflow and no valve timing to open and close at certain rpm's. With optimum air volume in the intake chamber, maximum torque is produced at any rpm's. This eliminates the need for a conventional transmission.
Multiple spark ignition, greater dwell time and better fuel to air ratio produce more complete combustion inside the combustion chamber. That means fewer emissions, less noise and better fuel efficiency. The company promises twice the fuel efficiency of a piston engine producing equal power.
With only 9 moving parts, the Vengeance engine is projected to cost 80 percent of an equivalent piston engine. Few moving parts also translate into very low maintenance costs and minimal repair costs.
Vengeance Power plans to license production rights to other companies.
