What is euro ll diesel engine?

Euro II diesel engines refer to a category of diesel engines that comply with the European Union's Euro II emissions standards, which were implemented in 1996. These standards were designed to reduce harmful exhaust emissions, including nitrogen oxides (NOx) and particulate matter (PM), compared to previous regulations. Euro II engines typically utilize technologies such as improved fuel injection systems and engine management to achieve better emissions control. While they represented a significant advancement at the time, subsequent standards like Euro III and beyond have further tightened emissions requirements.
