With the advancement and development of universal modern industry, the unruly of environmental pollution is getting worse. Further emission of industry, emission pollution of vehicles and motorcycles is progressively noticed. The corresponding emission rules of law are also increasingly strict. From 2009, the minimum emission value of two-wheel motorcycle is regulated in Pakistan by EPA (Environmental Protection Agency, of Pakistan).
Exhaust pipe emission includes CO (Carbon Mono oxide), HC (Hydro Carbons), NOx (Nitrogen Oxide) and CO2 (Carbon Dioxide).
Emission from vehicles are controlled through as per standards of Pakistan Environment Protection Agency (PAK-EPA) under clause (e) of session 6(1) of the Pakistan Environment Protection Act, 1997, and with the approval of the Pakistan Environment Protection Council, established national environmental quality (NEQS) as follows:

Structure and working principle of EURO-II (emission control unit, ECU):
Emission control unit mainly includes air pump, air cleaner, connecting pipe and accelerant-catalyzing device.
The air pump, in accordance with the principle of engine ripple control, controls the air flow volume. Fresh air could be inhaled into the drained pipe and mixed with the un-burnt CO, HC which exhausted from combustion room. This device could help to reduce the exhaust emission of motorcycle and to reach the Euro-2 emission standard.





European emission standards define the acceptable limits for exhaust emissions of new vehicles sold in EU member states. The emission standards are defined in a series of European Union directives staging the progressive introduction of increasingly stringent standards.
Currently, emissions of nitrogen oxides (NOx), total hydrocarbon (THC), non-methane hydrocarbons (NMHC), carbon monoxide (CO) and particulate matter (PM) are regulated for most vehicle types, including cars, lorries, trains, tractors and similar machinery, barges, but excluding seagoing ships and aeroplanes. For each vehicle type, different standards apply. Compliance is determined by running the engine at a standardised test cycle. Non-compliant vehicles cannot be sold in the EU, but new standards do not apply to vehicles already on the roads. No use of specific technologies is mandated to meet the standards, though available technology is considered when setting the standards. New models introduced must meet current or planned standards, but minor lifecycle model revisions may continue to be offered with pre-compliant engines.
