TIER 4 EMISSIONS REGULATIONS – WHAT TO EXPECT

The tier 4 emissions regulations were introduced to most designers, engineers and industrial operators a few years ago. These regulations govern the emission of off-road equipment. There are many design challenges that have been overcome following the introduction of these regulations. The industrial sector has no other alternative other than to meet the requirements that they are being give. These regulations are meant to reduce the emissions of various industries and make the environments cleaner and safer. When the manufacturing industry began the preparation for tier 3 emissions, there were numerous challenges that had to be overcome. This involved the building of new engines that required new mounting spaced and substructures. The engines also needed to have greater cooling capacities. However, with the tier 4 emissions regulations more challenges are expected. Most of the engineers who had overcome previous challenges are now exposed to a new set of challenges that exceed anything they have ever faced in the past. The regulations have made the emission standards stricter than ever before. In addition to that, they will also mark a complete redesign of most of the machines and equipment that are used.

The tier 3 emissions regulations led to changes such as increased engine space claims, more airflow and increased cooling capacities. The engine hoods were redesigned together with the covers. This was meant to stuff more air into the engine. These regulations pushed machine design to its limits while ensuring overall clearance in the width, length and ground clearance. The tier 3 machines required additional cooler and engine compartments that left no room for devices such as the diesel particulate filters in the coming tier 4 emissions. The tier 3 machines were packed, crammed and filled in the best possible way as required by the regulations. This left major challenges to the engineers who wondered where new items would be placed for tier 4 emissions. This created a new set of challenges that had to be overcome. The only way to overcome the challenge was by complete redesign of the machines. This option was not an easy one. However, it has been possible for most manufacturers to redesign their machines and create lengthened frames that have new placements for the existing counterweights and driveline components. There is need to purchase new equipment to be able to meet the standards by the manufacturers. The good news is that there has been a reduction in the cost of production and manufacturing these machines. As a manufacturer, you need to find ways of meeting the emissions regulations in your industry.
