Farm equipment is still in the process of being moved to smokeless engines. Environmental regulatory agencies have a main focus on four types of engine emissions. These emissions are carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter (John Deere). The reason engines have to be redesigned is because of the government Interim, and the government believes these four factors are not good for the environment. The main targets the government is focusing on are all the trucks and equipment that use any of the four engine emissions. Non-road emission reductions have been put in place and some of the reductions are still not accomplished. The regulations are being made, but companies are also developing better diesel engines that do not produce harmful emissions. Companies such as John Deere.
John Deere has cut down NOx through cooled exhaust gas recirculation. They are the first company to produce the the EGR cooling system. The engine works by removing oxygen from the air. Valves open up, then measured amounts of cooled exhaust gasses are sent back int the machine and are combined with fresh oxygen (John Deere). This company may be the first to produce this type of engine, but other companies are following John Deere’s footsteps.
The government is happy about the companies developing better engines, but they still are implementing restrictions with a reduction process. The stages of the reduction process are as followed: “Tier 3/Stage III A emissions regulations required a 40 percent reduction in Nox compared to Tier 2/Stage II. Interim Tier 4/Stage III B regulations require a 90 percent reduction in PM along with a 50 percent drop in NOx compared to Tier 3/Stage III A. Interim Tier 4/Stage III B and Final Tier 4/Stage IV must pass additional emissions tests including the steady-state 8-mode test (ISO 8178) and the rigorous non-road transient cycle (NRTC) test. Final Tier 4/Stage IV regulations, which will be fully implemented by 2015, will maintain levels of PM and require an additional 80% reduction in Nox compared to Interim Tier 4/Stage III B” (John Deere). To understand these reductions more, the image below puts the text into a visual form.
The regulations have been a hassle for the operators of diesel engine machines or trucks, but the regulations are good for the environment. To keep our world here, we need to cut back on many things that harm the environment, and diesel engines emitting harmful substances is one of them. The emitting of harmful substances is also bad for the human population, and animal population. In the air, we cannot see all of the particles being admitted, but our body feels the impact. New technology companies are redesigning diesel engines, and these engines will only benefit the whole planet. The regulations are a great thing being implemented so we can have a healthy environment with healthy plants, animals, and humans in it.
