WHAT CHANGES DO MANUFACTURERS HAD TO MAKE IN ORDER TO MAKE EURO COMPLIANT VEHICLES?
The following changes normally will be made by manufacturers in order to have a EURO I compliant car. Typically, the following areas would require attention: (a) carburetor retuning (b) secondary air intake (c) re circulation (d) catalyses capacity increase (e) trimetal coating in the catalyses.
Changes for having a Euro II compliant vehicle require that the carburetor be replaced by an MPFI system i.e. a Multi-point spark plug, while in the latter, atomized liquid fuel is injected with the help of a fuel pump and a nozzle into a cylinder full of hot compressed air, which results in ignition taking place. Larger cylinders which need more fuel require more than one injector, thus resulting in a multi-point fuel .. There are two basic types of engines, spark ignition and compression ignition engines. In the former, fuel ignition is triggered by an electric spark from a
