A review of representative warranties from major truck engine manufacturers shows that the use of a non-OEM fuel supplement like Nx25 does not invalidate such warranties. Base engine warranties are not invalidated unless claimed failures or damages are a result from unauthorized modifications of the engine or if they are caused by the use of a non-OEM supplement. Rivotto’s Nx25 occurs below trace levels and is not known to cause any adverse effects on engines, and thus does not invalidate base engine warranties.

OEM engine warranties do not apply to accessories or additives which bear the name brand of another company, and will not warranty any non-OEM part or result to the engine determined to be caused by the non-OEM products. If a user of any non-OEM product files a warranty claim with the manufacturer for any covered warranty item on an engine or vehicle manufacturer’s warranty and the manufacturer attempts to deny that claim on account of the non-OEM product, the terms of warranties available and reviewed by Rivotto provide that the manufacturer would have to prove that the failure or damage was caused by the non-OEM product to be successful in holding their denied claim. Nx25 is not known to have ever been a suspected cause of a warranty claim on an engine or emissions system and has never been party to a denied warranty claim.

Our technology has never damaged an engine, nor has it ever been cited as a cause for a claim denial for a faulty engine. In fact, our technology can help avoid engine problems. Typically, unburned molecules can remain within the crankcase, building up residue on engine components and contaminating oil. Nx25 reduces pollutants resulting from combustion, which greatly reduces residue on engine components and contaminants in oil.

Over the past decades, automakers have made dramatic improvements to engine performance.  

For various reasons, automakers have long neglected peripherals that improve engine efficiency, and in recent years, on account of growing social and regulatory pressures, have instead primarily focused their attention on whole engine solutions and other enhancements mandated by governments to reduce emissions, including:

• Stop-start systems
• More efficient catalytic converters
• Adding electric vehicles to their product mix to meet CAFÉ laws

In addition, recently many car companies have started to de-emphasize improvements in combustion engines and to prioritize investment into electric vehicles. (GM recently merged their I.C.E. engineering team with their EV team, a clear indication of where the industry is headed.) This doesn’t mean, however, that we’ve reached the end of the road for combustion engines. For example, in 2021 the US Department of Energy published their annual vehicle technology officer report covering 2020 and estimated that combustion engines could still be made 30% more fuel efficient, and that by 2050 combustion engines would still dominate the road by a high margin.

In 99.9% of cases, inventors are not businesspeople or marketers. Inventors are brilliant people, and in many cases their brilliance in inventing doesn’t lend to business skill. Lack of business and marketing savvy is an obstacle to many technologies not successfully getting to market. There are thousands and thousands of unused technologies sitting on the shelves of academic and research institutions and in the personal libraries of inventors. Few innovations become patented, even though they may be remarkable and useful. Even among technologies that are patented, according to Forbes, fewer than 5% of patents get to market, and then among those 5%, a much smaller number are successful at scale. It takes relationships, business expertise, and capital to commercialize even the best of intentions. At Rivotto, our team of experienced business people specialize in linking arms with brilliant inventors and in taking their compelling technologies to market.

Nx25 has shown in testing to enable slightly cooler operating temperatures, in addition to other benefits.

Many emissions form during the period called ignition delay after the spark has fired (gasoline) or after fuel has been injected into the high-pressure environment (diesel). Think of ignition delay as a very brief smoldering period that occurs just prior to the charge of fuel flashing, kind of like a log in a firepit that hasn’t yet caught on fire even though a flame is present. Also, some emissions components may form after the flame has propagated, either through charge of fuel (if the flame didn’t propagate smoothly) or if the charge didn’t burn completely.

Nx25 reduce ignition delay and provide a faster cleaner burn as the flame front propagates through the charge of fuel inside the cylinder. Importantly, faster combustion moves the process closer to the ideal situation of constant volume combustion where optimum energy transfer is obtained.
