by Isaiah Richard (Tech Times) Diesel engines may find a new way to survive in a zero-emissions future. — Diesel engines may still get a chance to survive in the future because of the latest research and claims from the University of New South Wales. In their study, its team made a hydrogen-diesel engine hybrid that injects the compound into its block, something which helped gave tremendous results which they may soon apply to modern diesel engines.

In this diesel-hydrogen hybrid, the team found that it significantly reduces emissions caused by conventional diesel engines alone, something that could be used in the future.

The University of New South Wales, led by Professor Shawn Kook, published research in the International Journal of Hydrogen Energy, detailing its recent discovery of combining diesel and hydrogen fuel into an ICE engine.

Its study entitled “Direct injection of hydrogen main fuel and diesel pilot fuel in a retrofitted single-cylinder compression ignition engine” delivers a new life for diesel engines to thrive in the future.

This is because the researchers found a way to significantly reduce the CO2 emissions made by a regular diesel engine by up to 26 percent when running on a 90 percent hydrogen and 10 percent diesel fuel ratio.

According to the team, existing diesel engines widely used on trucks and the like “could ultimately be retrofitted to the new hybrid system in just a couple of months.”

Additionally, the researchers found out that these hydrogen-diesel hybrids also help in improving fuel efficiency by as much as 26 percent. READ MORE
