WHY REHLKO GASOLINE

The structural completeness
of small engines

REHLKO gasoline engines are not a mere power source. They are a structure-centered platform designed to suit industrial equipment.

5.5–38 HP output range

Single- and twin-cylinder lineup

Applied to garden and construction equipment

A global network of 10,000+ service points

The smaller the engine, the more structural completeness matters.

REHLKO Technology Advantages

Overhead-valve (OHV) design

→ Improved volumetric efficiency,

complete combustion, low oil consumption

Hydraulic valve lifters

→ No valve-clearance adjustment needed,

minimized noise

Fully pressurized lubrication system

→ Continuous oil supply to all bearing surfaces
→ Oil-change intervals up to 100 hours

Cast-iron cylinder liners

→ Enhanced durability, re-machinable

Oil Sentry System

→ Automatic warning and engine protection

when oil pressure drops

Quiet Pulse Operation

→ Noise-minimizing design

EPA / CARB emissions certification
