What's new at CONEXPO-CON/AGG, Part 2 of 2

A preview of some of the products and technologies that will be displayed at this year's event, scheduled March 15-19 in Las Vegas, NV.

Yanmar America's Tier 2-compliant TNV liquid-cooled diesel engines for construction and agricultural equipment include seven direct-injection models with rated outputs from 30.2 to 83.5 hp (23 to 63 kW) at 2500 to 3000 rpm and three indirect-injection models with rated outputs from 13.4 to 26.1 hp (10 to 19 kW) at 3600 rpm. The indirect-injection models feature improved combustion and fuel-injection systems for cleaner combustion. A new inline fuel-injection pump provides similar fuel-injection equipment performance to that of direct-injection engines. A load timer adjusts injection timing according to engine load. The direct-injection models in both three- and four-cylinder configurations have the injection nozzle set at a larger angle to improve consistency of atomization and mixing. This feature improves combustion efficiency and startability while reducing noise and emissions.
