Low-Emission Engines for Construction

For machine operators, generous torque is critical, as it provides low revs, prompt response, low fuel consumption, low life cycle costs, low power-to-weight ratio, and so much more. Now, low-emissions industrial engines are more often being used to power equipment.

Such is the case with a new partnership between Scania and Kobelco Construction Machinery. Scania’s engines will power Kobelco’s new models of the 300t hydraulic crawler cranes. More specifically, it will supply 13-litre low-emission industrial engines for use in crawler cranes with a lifting capacity of 300 metric tons. The first product will be launched in the United States—and then worldwide.

Scania’s 13-litre 331kW industrial engine meets the Stage IV/Tier4 final/Japan H26 emission standards without the need for a particulate filter. Customers in countries with emission standards will benefit from the low-emission engines.

While this is one example, the trend lately is toward more low-emission engines for the construction industry. Fuel economy and greenhouse gas emissions are becoming major drivers in the development of more advanced, energy-efficient internal combustion engines.

At the same time, new technologies, as well as improvements to existing technologies, are required for diesel engines.

The Diesel Technology Forum suggests diesel technology can help reduce petroleum consumption as well as greenhouse gas emissions. It indicates that it also provides a platform for other alternative technologies such as hybridization and the use of biofuels.

At the end of the day, clean diesel and low-emission industrial engines can lead to a cleaner environment and a stronger economy.
