Honda's New Generation V-Twin Engines

The new GX V-twin series engines are redesigned to offer more power, easy integration and better fuel economy, all in a more compact package to OEM equipment.

There are six new V-twin models (GX/GXV630, GX/GXV660, GX/GXV690) that replace the existing models (GX/GXV610, GX/GXV620, GX/GXV670.

The new engines, available in both horizontal and vertical shaft configurations are designed for lawn and garden equipment, construction equipment, generators, fire fighting pumps, Hydraulic Power Pack and other professional heavy-duty applications.

The new V-Twin features an advanced style that looks quite different from other engines in its class. A number of new elements, including a hemispherical combustion chamber, high compression ratio, variable ignition timing (digital-CDI), and an integrated cylinder and head structure, all contribute to an enhanced overall performance while exceeding the world’s most stringent emission regulations without the use of a catalyst.

Improved cumbustion, Improve- ments in cooling performance, Improved lubrication system, Ignition with digital CDI, Improved dust resistance and easy to use are the important features.

Environmental performance is ensured by using Honda’s improved combustion and friction reduction technology, the new V-twin exceeds the world's most stringent emission standards without a catalyser (CARB Tier III/2011EPA).

The improved fuel efficiency and high level of output are two of the biggest benefits for the new V-twin. Significant improved fuel consumption, approximately 10% lower than the former V-twin engines, is achieved by efficient combustion and optimal ignition timing set by the digital CDI unit. Besides lower fuel consumption and lower emission, mechanical noise is reduced by using aluminium pushrods and a resin type camshaft.
