Honda this year launched its mid-GX engines line. Completely redesigned, the GX120, GX160 and GX200 are single-cylinder, horizontal-shaft engines replacing the existing models. The line is designed for commercial turf applications, generators, water pumps, pressure washers and an array of construction/industrial machines. While dimensionally equivalent to the engines they replace, the GX series offers improved fuel economy through changes in valve timing, compression ratio, carburetor settings and cooling system modification. The engines feature more stringent emissions standards. Lower noise levels are achieved through a change in muffler structure design, breather valve, push rod materials and crank/case cover rigidity, with reduced vibration accomplished through a lighter engine piston.
“Because the new engines essentially match the dimensions of the existing GX models they replace, original equipment manufacturers will not have to modify the designs of their commercial equipment,” said Mike Rudolph senior manager of Honda Engines. The new Honda GX120, GX160 and GX200 mid GX engines meet EPA Phase 3 exhaust and evaporative emissions standards.
