Technology
Massive Continuous Torque
The crankshaft mechanism has served a vital role in internal combustion engine design for more than 130 years. However, despite continuous refinement and incremental improvements over time, the crankshaft has reached the end of its useful life.
Crankshaft geometry has inherent design limitations in the transfer of linear force to rotational power. A crankshaft-based engine achieves its peak torque for only one brief moment at close to mid-stroke.
The CVE design achieves its maximum torque starting at 8%* of the stroke after TDC and maintains maximum torque for over 90%* of the stroke after TDC.
Side-by-side static testing of equal displacement crankshaft based versus CVE Technology based designs show that the CVE design boasts a 58%* improvement in torque over today’s crankshaft engine design.
The patented CV Engine/Technology (CVE) replaces the crankshaft completely with a Powershaft and Rodrack Assembly, which fundamentally alters the geometric relationship of the motion of the piston stroke relative to the movement of the rotating shaft. It continuously converts linear reciprocating piston motion to rotary movement and vice versa in the most efficient manner possible.
Fuel Efficient
When comparing engine designs producing equal power:
The fuel required by the crankshaft-based engine is far greater because:
- The amount of fuel injected into the cylinder must be substantial enough to last until mid-stroke, where a momentary maximum transfer of linear motion to rotational power occurs
- Due to the asynchronous motion of the opposing pistons, an increased amount of energy is required to propel these pistons through their cycle in order to rotate the crankshaft and drive the other pistons not engaged in the power stroke
- The geometry of the crankshaft to connecting rod to piston connection creates drag and friction due to piston side load on the cylinder walls
- The pistons are not traveling at a constant velocity and are operating at continuously varying speeds throughout the stroke, which creates a pulsation within the crankcase
The fuel required by the CV Engine design is far less because:
- The CVE design requires only a small amount of fuel at the top of the stroke to propel the piston down the cylinder to create continuous maximum transfer of linear motion to rotational power occurs
- The piston and rodrack assembly is one integrated component that is in perfect linear alignment, permitting the pistons to move in synchronous motion, requiring minimal energy to propel the full cycle
- Drag and friction due to piston side load on the cylinder walls is non-existent in the CVE engine design due to perfect linear alignment of the piston and rodrack assembly and the linear bearings that support the travel of the rodrack assembly
- The pistons in the CVE are traveling at a constant velocity and are operating at constant speeds throughout more than 80%* of the stroke, virtually eliminating pulsation within the CVE Powercase
Reduced Emissions & Environmental Impact
When comparing engine designs producing equal power:
Crankshaft Engine Design
- In a four-stroke crankshaft-based engine, the fuel required to obtain optimum performance must be sufficient to sustain combustion until the piston reaches mid- stroke and the fuel charge must simultaneously increase in volume as the volume within the cylinder increases as the piston travels to mid-stroke.
- Due to the required duration of combustion and required piston travel within the cylinder, only half of the stroke remains to eliminate the fuel charge, therefore the entire volume of fuel required cannot be burned by the time the power stroke is complete
- The unburned fuel is therefore wasted and creates additional harmful emissions in the exhaust gasses, which must be captured and processed by the catalytic converter. The use of engine exhaust scrubbing devices such as diesel particulate filters and catalytic converters, which require expensive precious metals such as platinum, palladium and rhodium.
- Due to crankshaft geometry, the piston is subject to side-loading. This side load not only creates friction and drag and negatively impacts torque, the unloaded side of the piston creates a gap between the piston and the cylinder wall, allowing exhaust gases to escape into the crankcase, contaminating the engine oil, requiring frequent and environmentally impactful oil and filter changes.
- According to Lafayette University, almost 30% of all US global warming emissions result from America’s transportation sector. 60% of U.S. transportation emissions come from cars and light trucks, which conveys the significant role vehicle exhaust from internal combustion engines in passenger cars has on our environment and community health.

CV Motion Technology Engine Design
- In the CVE four stroke design, optimum performance is achieved at the top of the stroke, where the volume of the cylinder is relatively small, requiring significantly less fuel to generate the maximum transfer of power
- The maximum transfer of power occurs at close to the top of the stroke in the CV Engine design. This short duration combustion phase allows for nearly the entire stroke to be utilized to complete the total combustion of the smaller required fuel charge by the time the exhaust stroke is initiated
- Due to the absence of the majority of unburned fuel and harmful emissions, the need for a catalytic converter in gasoline engine applications is completely eliminated. The cost savings on a per engine basis is significant. Corresponding reductions in emissions are achieved in diesel engine applications which may permit the elimination of exhaust scrubbing devices such as diesel particulate filters
- In the CVE design, the piston and rodrack assembly functions as one integrated component that is in perfect linear alignment and therefore does not allow the piston to come in contact with the cylinder wall. This eliminates piston to side load. This minimizes drag and friction and eliminates the heat produced by the contact of the piston with the cylinder wall.
- The CVE operates with a fully sealed powercase, much like a sealed transmission case. The lack of piston side loading combined with the sealed powercase prevents combustion by-products from entering the powercase, preventing contamination of the engine oil, virtually eliminating environmentally impactful oil and filter changes.
- The forecasted 70% reduction in exhaust emissions from the use of the CV Engine in all modes of fueled transportation would translate to a reduction from 8,887 grams of CO2 per gallon of gasoline burned to 2,667 grams of CO2 and a reduction from 10,180 grams of CO2 per gallon of diesel burned to 3,054 grams of CO2. The potential impact of the CV Engine on reducing global warming emissions from carbon dioxide is enormous.

Smaller
To illustrate the significant reductions in physical size that can be achieved via the CVE design, a direct comparison with a comparable crankshaft-based engine follows.
When comparing engine designs producing equal power:
| Specifications | Crankshaft Engine Design Subaru FB25 (4cyl, 4 stroke) | CV Motion Technology Engine Design A02 Version (4cyl, 4 stroke) |
|---|---|---|
| Horsepower | 170 | 193 |
| Displacement | 152.4 cu or 2498 cc | 27 cu or 443 cc |
| RPM | 5800 (non direct) | 2450 (direct, not geared) |
| Height | 23.63″ | 10″ |
| Width | 32.67″ | 14.5″ |
| Length | 16.93″ | 11.8″ |
Lighter
The CV Engine design eliminates the crankshaft, the second heaviest component of an internal combustion engine after the engine block.
The CV Engine produces the same power from a much smaller displacement and therefore is lighter overall. The CV Engine also requires fewer total parts in its construction and these parts are generally smaller and lighter as well.
The high compression pressures required in the crankshaft-based design impacts many aspects of the overall engine design, as multiple components must be made robust enough to withstand the very high pressures, which translates to significantly increased engine weight. The CVE design operates at substantially reduced pressures (gas or diesel) which allows for the weight of both the engine and the related subassemblies it would be installed in to be much lighter.
The combined effect of the elimination of the crankshaft, the physically smaller components comprising the engine and the ability to assemble the engine with components of an overall lighter weight construction translates to significant weight savings, on the order of hundreds of pounds even in a modest car size engine.
