For cars using internal combustion engines, purification of exhaust gas is a top priority. Relying on various advanced technologies, Isuzu engines can successfully meet the emission regulations of various countries. Isuzu diesel engines have high thermal efficiency, ideal fuel consumption, very low carbon dioxide emissions that cause global greenhouse effects, and high durability. In the field of heavy trucks and buses, Isuzu will not consider the development of vehicles other than diesel engines in the future. Therefore, Isuzu is also actively solving the problem of nitrogen oxides and particulate emissions, which are the shortcomings of diesel engines, and providing safe and reliable solutions to reduce it. Not only engine performance, Isuzu is also making unremitting efforts to improve overall vehicle performance such as running costs and carrying capacity.
