1. DPF (Diesel Particulate Filter)
Isuzu pioneered developed of the DPF system. By switching between two filters, particulate matter and black smoke can be incinerated in one filter while the other continues to trap pollutants. Heat-resistant and durable ceramic is used as the material for filters. Dense and rough, these filters are highly effective. In addition, the large surface area of the filter fibers traps even more PM and black smoke to clean up exhaust gases.
2. Continuously Regenerating Diesel Particulate Trap (Panel exhibition)
This system changes the nitrogen monoxide in exhaust gas into nitrogen dioxide by means of an oxidation catalyst and constantly incinerates particulate matter collected in the filter. Product development continues. Currently, deterioration of the catalyst due to the high sulfur content of light oil has yet to be resolved. Reduction of sulfur in light oil is a future task.
3. NOx Catalyst (Panel exhibition)
Much like the DPF system, this is another after-treatment to clean up diesel engine exhaust. The system changes NOx into harmless substances such as N2 (nitrogen) and H2O (water).
For this year's Motor Show, Isuzu presents a panel exhibition of a NOx catalyst utilizing urea as the reducing agent. The NOx catalyst system owes its effectiveness to the ammonia contained in the urea solution that is injected into the exhaust.
4. One-Way Cooled EGR system (Panel exhibition)
By mixing exhaust gas with intake air and controlling the amount of oxygen during combustion, the EGR (Exhaust Gas Recirculation) system greatly reduces NOx. A cooler and check valves are utilized in the one-way cooled EGR system to increase its efficiency by lowering combustion temperatures and preventing back flow of intake air, which can occur with turbo-charged engines.
