Yanmar Increases Displacement of MINIMAX 15% and Power Output by 20%

Buffalo Grove, IL September 2, 2008 Yanmar announces the expansion of the 

MINIMAXÂť series diesel engine solution for lawn and garden equipment, small 

agricultural machines, utility vehicles and compact generators. Model number 3TNM72

is the newest version in this series. This 903cc threecylinder Tier IV compliant engine

utilizes Yanmar™s proprietary indirect injection technology to achieve low fuel consumption and emissions levels. The engine block for this ultra compact and high performance  power plant employs Yanmar™s latest structural technology to achieve low vibration,  noise and size.


High Power Density

Thanks to this brand new, highly efficient cylinder block design, Yanmar has been able 

to achieve higher output levels relative to the size of the engine™s mass.


Compact Size

Due to the compact dimensions, the MINIMAX is a perfect fit for applications that 

have tight space requirements and demand high, reliable power output. Additionally, 

the universal base attachment design means the MINIMAX is perfectly suited as a 

replacement engine for a variety of equipment.


Low Noise & Vibration

High rigidity is achieved by incorporating a ladder frameÂť structure in the engine 

block casting. This reinforcement allows the MINIMAX to operate with low noise and

further reduced vibration.


Environmentally Friendly

The MINIMAX incorporates Yanmar™s new proprietary MC type injection pump to 

achieve precise fuel delivery, reduced fuel consumption and low emissions. This engine 

is already compliant with EPA Tier 4 regulation.


Full Line Up

In addition to the TNV product line, the new MINIMAX series was first released last 

year with the introduction of the 3TNM68 (784cc). The new MINIMAX, model 3TNM72, is bored and stroked to an overall 903cc displacement and delivers 20% more horsepower than similarly sized competitors. Both engines in this series will be built at the Yanmar engine manufacturing facility in the Shiga prefecture in Japan.
