Mini 4-Stroke Series Engines
Honda has once again applied its superior engine technology and decades of automotive, motorcycle, and power equipment experience to create the world's first 360°-inclinable 4-stroke engine.

Designed with Honda's trademark ultra-lightweight and compactness, the miracle Mini 4-Stroke efficiently delivers the kind of clean, powerful, quiet performance that makes it the powerplant for an incredible array of portable equipment and applications. Some applications include string trimmers, brush cutters, backpack blowers, mini-tillers, water pumps, generators, hobbyist applications and cement screeds/trowels.

Honda's Mini 4-Stroke Technology


A clever rotary-slinger pumping lubrication system keeps oil in a completely misted state and circulates it using pressure fluctuations generated by the movement of the piston. Built-in passages effectively return the circulated oil to the oil reservoir from every part of the engine, and an oil return port positioned in the center of the reservoir ensures that oil cannot accidentally flow into the combustion chamber.
