Australia's Green Diesel Corporation has developed a pump injector that changes diesel technology parameters as we know them today. Moreover, it solves the main cost and environmental dilemmas of today's diesel technology.
Words: Tim de Jong
The Green Diesel Corporation was set up by Ron Kukler, an Australian engineer who's worked with several technology companies before he decided to start his own, based around an invention that can be genuinely thought of as 'innovative: His invention is effectively a unit injector that delivers about seven times higher peak injection pressure than other manufacturers' injectors. To reach this ultra-high pressure, Kukler makes use of the cylinder pressure. This leads to peak injection pressures of about 160.000 psi, or 11.000 bar. This is key to vastly improved fuel efficiency and reduced emissions.
Combustion -Complying with Euro-6 and EPA 10 is a piece of cake with this system," Kukler claims. It means the end of uncontrolled combustion and diesel knock, too.
Kukler adds that his system has a reduced impact on engine wear and is less costly than competitors' fuel systems. It's also easier to maintain than rivals as it uses fewer parts than existing set-ups.
According to Green Diesel, most fuel systems cost about 25% to 30% of the actual engine cost, including expensive add-ons, but it says its own system costs just 3% of the actual engine cost.
"We do not use a complicated and expensive high-pressure pump, and our electrics are simple," insists Kukler, adding: "Most existing engine management systems operate effectively with the Green Diesel Fuel Injection System."
Kukler's system operates with hydraulics. No externally driven high-pressure pump is required, and according to the man himself: "It is new technology, borrowing very little from the past."
Durability testing of the system for the equivalent of one million miles (1.6 million km) showed no wear, according to Green Diesel. For US government purposes, Kukler has successfully modified petrol engines to diesel engines to reduce engine costs and to increase engine life.
Investments He is now looking for further funding of his project as Green Diesel intends to expand into Europe and the US. The company has visited a show in Stuttgart, but it has struggled to find a European partner. "The truck industry has tended to deny our existence until now," Kukler says. Green Diesel intends to produce its system in the markets where it hopes to sell, which should, apart from Australia, be the US and Europe. •
