US firm Parker Racor has announced that its German research and Thai manufacturing arms have developed a small-sized fuel filter/water separator for the new 1.5-liter diesel engines that are being used in the Mazda 2. The company says this is the first time that Mazda has selected a filter manufacturer from outside of its Japanese home market.
The requirements were stringent: Mazda’s Skyactiv technology uses low engine compression ratios in its diesel engines to meet emissions targets without the use of expensive after-treatment systems. The product had to offer efficiency of 98% at 5µ filtering capability and manage high dust holding capacity, while water separation above 99% was also required.
Furthermore, the suction side filter had to fulfil burst pressure up to 2 bar, while customer wax-up (cold start) requirements also had to be met.
Mass production and ease of assembly were another challenge for Parker Racor engineers: the new fuel filter/water separator is secured with two M6 screws to ensure rapid assembly.
“For Parker Racor this is a very prestigious project,” said Burkhard Hartmann, R&D officer at Parker Racor, Stuttgart. “Utilizing all of our engineering expertise in the fuel filter industry that has been built over our long-standing history, we were able to take the required specification and match it exactly.”
