Honda Adds More Horsepower to Its Engine LineUp

3/3/2003 7:17:41 PM

Honda has announced the addition of two new, higher horsepower (hp) engine models to its popular GC Series four-stroke line. The 6.0 hp GC190 and 6.5 hp GCV190 engines are designed specifically for premium, residential power equipment applications.

Horizontal shaft GC190s and vertical shaft GCV190s are available through Honda Engine distributors nationally. Intended for use on such high volume applications as pressure washers and lawnmowers, both shaft configurations also will be supplied to other power equipment manufacturers on an OEM basis.

"GC engines are an increasingly important segment of our model line-up and have been an important driver for our growth in North America," said Scott Conner, Honda Engines senior manager. "Our new GC190 and GCV190 engines exemplify our commitment to meeting customer demand for increased power and flexibility."

As with other overhead cam (OHC) engines in this series, a unique combination of the world's first internal timing belt and uniblock construction creates a lighter and more compact package than anything else in the class, delivering an unparalleled power-to-weight ratio. This simple construction also minimizes the number of moving parts, making the engine reliable, quieter, and easy to operate.

An increase of 1.0 hp over the GC160 and GCV160, to 6.0 hp and 6.5 hp for the GC190 and GCV190 respectively, was achieved through an increase of displacement from 160 to 187 cubic centimeters. This also results in a 0.5 lb/ft torque increase for both engines, with the GC190 delivering 8.9 lb/ft, and the GCV190 delivering 8.1 lb/ft.

To maintain Honda's exceptional reliability with the higher output, internal components have been strengthened through the use of a stronger piston pin, larger connecting rod, larger rod journal, and redesigned oil control ring.

A horizontal cross-flow intake port smoothes the flow of fuel into the combustion chamber, optimizing the engine's ability to deliver fast, reliable starts, while a compact combustion chamber and overhead cam configuration reduce fuel and oil consumption as compared with conventional side-valve engines.

Honda's unique Auto Return Choke System (ARCS) - available on fixed-throttle GCV variations - prevents over-choking of the engine, enhances ease of starting, and provides customers with a more user-friendly alternative to the traditional primer bulb system found on many competitive engines. The speed with which the choke returns automatically varies with ambient temperature.

Honda is the world's largest producer of engines, selling more than 15 million annually across its product lines. Its new GC190 and GCV190 engines will be produced primarily at Honda Power Equipment Mfg., Inc., in Swepsonville, North Carolina, using domestic and globally-sourced parts.
