Kawasaki Engines unveiled a new line of engines that it calls EVO. The company says the line features electronic fuel-injected (EFI) engine that Kawasaki says offers increased power density and improved fuel efficiency.

“Our new EVO line of engines represents the latest in trusted, efficient performance from Kawasaki Engines,” Nelson Wilner, division vice president of Kawasaki, said. “We poured our collective experience and engineering know-how into creating the most efficient, powerful engine we could, and we’re extremely proud to now make EVO available to our customers, dealers and end-users.”

The company says EVO’s increased power density and efficiency are the results of enhanced intake and a technologically advanced throttle control system. Kawasaki EFI integrates electronic throttle control and an advanced electronic control unit to continuously match mower engine power to cutting load and ground speed.

EVO engines include the following features:

  • Intake efficiency. The compact layout allows for a more direct air path and the flow area has also been increased. The shorter path and larger area result in enhanced intake efficiency, which delivers higher performance and improved fuel economy.
  • New cylinder head design. The FX EVO features cylinder heads with intake and exhaust ports optimized for efficiency and improved flow, according to the company. The low-pressure casting technology results in high-strength, temperature-resistant heads.
  • 3-valve cylinder head. Each FX EVO engine’s cylinder head features three valves, two intakes and one exhaust, with increased diameters. Kawasaki says benefits include increased efficiency, improved combustion and reduced exhaust emissions by helping the engine breathe easier.
  • Pent-roof combustion chamber. The combustion chamber design features a pent-roof construction and three valves that generate a stronger tumble flow. Stronger tumble flow encourages better flame propagation, which improves combustion.
  • Oversized inspection cover. Kawasaki increased the size of the inspection covers and clean-out ports on the new FX EVO for ease of maintenance. The enlarged structure allows for more efficient grass removal from around the cylinder head and cooling fins and allows access to the intake manifold and fuel injectors without removing the fan housing.
  • Larger oil fill. The FX EVO engine’s dipstick and fill tube have a larger diameter compared with the FX850V EFI, while the cap features a quarter-turn design.
  • Cyclone air filtration. The multi-stage FX air filtration system provides the engine with clean, filtered air by swirling heavy grass, dust and debris away from the filter and other engine components.
