Vanguard Rolls Out New Global Single Cylinder Engines

Vanguard Commercial Power has released a new line of single-cylinder horizontal shaft commercial gasoline engines. The new line will span from 5.0 to 13 gross horsepower to meet power requirements for a wide range of global commercial applications.

The new line was designed with extensive customer input and aims to boost productivity while improving total cost of ownership.

“We interviewed hundreds of stakeholders including rental houses, end users and dealers worldwide to better understand the issues they face; the need for improved starting, reduced maintenance, less noise and vibration, and better service and support."
- Jim Cross, marketing manager of Briggs & Stratton Commercial Power

The ground-up design process allowed Vanguard to engineer all-new carburetion, ignition and combustion systems to promote reliable starting in any environment. To secure four-season starting, the engine is designed to start at temperatures as low as -20 degrees Fahrenheit. In addition, all surfaces inside the carburetor that contact fuel feature a special corrosion and stale fuel resistant plating.

The new line of engines also include an advanced version of TransportGuard, Vanguard exclusive single ignition and fuel shutoff designed to prevent oil dilution during transport. The lever now incorporates throttle control. Furthermore, the engine’s dimensions and bolt configuration make it a drop-in solution for equipment powered by other engine manufacturers.

To reduce maintenance and downtime, the engine features an oil management system that allows the engine to run efficiently for up to 200 hours between oil changes.

An advanced fully-cyclonic air filtration system lessens downtime by extending recommended air filter replacement intervals to 600 hours.

Vanguard also engineered the engine’s main components to lessen the impact of vibration on performance and engine and equipment wear, as well as to enhance operator comfort. Vanguard also looked to reduce overall engine noise by turning to acoustic engineers who focused on reducing decibel levels while also accounting for the perceived harshness of the engine’s sound.

The first available model in the new single-cylinder line, the 6.5-gross horsepower Vanguard 200, will be available to OEMs and for engine repowers in 2018. The remaining models will be introduced over the next two years.

Vanguard operates through a single national distributor with nine locations in the United States. The company offers next-day delivery of more than 50,000 genuine parts and replacement engines to their commercial dealer network.

(All power levels are stated as gross horsepower at 3,600 rpm per SAE J1940.)
