Investigation on effect of cerium oxide additive in waste plastic oil fueled CI engine

In this study, the effects of incorporating cerium oxide into diesel and WPO blends were investigated to determine the potential of the blend as a fuel additive.
The study aimed to assess engine-performance, emission, and combustion properties of the blend.
The experiments utilized a single-cylinder diesel engine, and researchers prepared two different blends of WPO with 25% WPO in diesel and 50% WPO in diesel.
Cerium oxide was added to these blends at concentrations of 25 ppm and 50 ppm using an ultrasonicator.
The results demonstrated that increasing cerium oxide content in the blend (50 ppm) led to reduced CO, HC, and NOx emissions at higher loads.
For instance, B50 + 50 ppm exhibited lower CO and NOx emissions, while B25 + 50 ppm demonstrated lower HC and smoke emissions.

Furthermore, raising the CeO2 content from 25 ppm to 50 ppm resulted in a 3% increase in brake thermal efficiency.
Moreover, cerium oxide positively impacted combustion and performance properties of the blends.
Among the tested blends, the B50 + 50 ppm combination showcased the highest brake thermal efficiency, optimal air-fuel ratio, and the lowest specific fuel consumption.

In conclusion, employing cerium oxide as a fuel additive in diesel-WPO blends offers a promising approach for realizing a sustainable and environmentally friendly future.

(That brings up another subject: The pyrolysis of plastics:

If you can load up a cartridge with waste plastic that fits into and is heated by your car exhaust; you get a good bit of free fuel.
Normally the released gas is cooled and separated into diesel, petrol etc in a distillation tower.
But in this case; keeping them all as a gas is more practical as all fractions will then be/remain combustible. It also saves a ton of weight and space.

You also get to enjoy the pleasure of stopping every 30? minutes to run around scavenging for waste plastic and burning your hands somehow loading it into your modded exhaust.

You also don't want to scavenge any PVC IIRC and how does one know the difference.?
