3TNM72

3 Cylinder, 4-Cycle, Liquid Cooled Diesel Engine

Features

Clean Emissions

Building off the Yanmar reputation for clean, quiet, fuel efficient and reliable compact diesel engines MINIMAX has achieved compliance with 2008 EPA Tier 4 and EU stage III A exhaust emissions regulations.

Reliable, Durable, and Quiet

MINIMAX offers enhanced noise and vibration characteristics due to its Ladder Frame block design, a stiffer crank and pistons and finer tolerance in the journal. Gear noise reduction is achieved through an improved gear tooth profile resulting in less mechanical noise.

Fuel Delivery and Economy

A newly designed, in-line ML type fuel injector pump is utilized to assure more precise fuel delivery and control. The result is reduced emissions, improved performance over a wide range of applications and good fuel economy which assures that Yanmar’s reputation for superior starting characteristics continues.

Ultra-Compact and High Performance

MINIMAX offers best-in-class power density as measured by the ratio of the engine’s output relative to the engine’s overall external dimensions

Easy Installation

With 176 mm wide base, MINIMAX engines are easy replacements for most major applications in this displacement category.
