The FT730V-EFI is the first engine from Kawasaki to employ Vortical Air Filtration (VAF), an air-intake methodology that significantly combats many of the ongoing issues faced by lawn professionals as well as homeowners.
The VAF technology incorporates air intake methodology that is engineered to focus on getting clean air into the engine without also introducing external debris, such as loose grass clippings. Thanks to VAF, the FT730V-EFI also requires less maintenance as the pre-filter and filter can run for up to 50 hours before requiring cleaning.
The air intake system uses centrifugal air movement to move heavy grass, dust and debris away from the air filter, and then ejects accumulated debris out of the engine through a duckbill debris ejection valve. Once the ejection process is completed, only fine dust is left, which is easily trapped in the filter.
Grass entering the cooling air path system under normal mower use is easily removed through large clean-out ports located over cylinder heads. The clean-pout ports cover is neatly integrated into the VAF cover.
With the use of an integrated e-governor (eGov) that immediately adjusts engine power-to-load for maximum cutting power at higher speeds, the FT730V-EFI helps minimize the need for re-cuts.
The open loop design avoids the need for an oxygen sensor, and maintains low engine temperatures, which in turn helps reduce oil consumption contributing to a longer overall engine life.
