Axial Vector Energy Corporation (AVXC.PK), based in Portland, is on a mission to develop and license technology to take internal combustion engines to the next level. Axial has been able to create new, smaller, and lightweight internal combustion engines that produce more horsepower and three times the torque of conventional engines of the same size.

Axial currently has ten patents that have been filed or are in the process of being filed. Some of the company’s pending patent applications cover more than one aspect of the company’s current or previous configurations of the axial vector engine. A number of the pending patents have already been strategically registered in jurisdictions outside of the U.S. Axial already holds two issued patents: Barrel-Type Internal Combustion Engine and Piezoelectric Liquid Injector.

The most commonly known internal combustion engine, known as the Otto engine, uses pistons and connecting rods to drive a crankshaft in a reciprocating motion. The second most common engine, referred to as the Wankel engine, moves the pistons in a rotational or eccentric motion. Axial has created a third family of engines called the Barrel-Type Internal Combustion Engine. The Axial engine converts combustion energy into rotational energy like the Wankel engine but without the use of a crankshaft. The linear motion of the pistons is directly transferred into rotational motion via a sinusoidal-shaped main drive-cam that results in less vibration and more efficiently produced energy.

Standard fuel injectors on the market today are designed to inject a specific amount of fuel at high pressures to atomize fuel. The fuel injectors used in Otto engines inject fuel at various points. Typically, fuel is injected by sequential sprays or in a single injection into the intake air stream during the intake stroke. One issue of this type of process is that the late injection of fuel into the system causes less mixing and results in uneven combustion.

Axial has been able to develop a fuel injector that can provide an accurately mix ratios of fuel and compressed air in a finely controlled high-velocity spray that improves the atomization of the fuel. The Piezoelectric Liquid Injector is able to effectively adjust from delivering very small amounts of fuel at low speeds to greater amounts of fuel needed at full power. The Axial team has designed an injector that is not only more lightweight and efficient than existing injectors, but also one that is easy to build, assemble, and calibrate.
