The Reason Why Catalyitc Converter get choked in Pakistan is due to following reason.
The poor quality of petrol available in Pakistan is a major barrier to introduction of cars equipped with engines that meet the Euro 4 standards or above in this market, according to a senior executive of a South Korean auto manufacturer.the low quality of petrol is a problem because it is not compatible with eco-friendly engines,” Mr Hideo Takenaka, the Executive Vice President Sales and Marketing Hyundai Nishat Motor, said while speaking to Dawn.
“We can import sensitive Euro 4 standards (and higher) compliant cars if fuel quality is upgraded … even start assembly (of such vehicles locally) but for poor quality of fuel, a problem unique to Pakistan. We are still analysing the market though,” he added. Initially, his company plans to import and assemble Euro II and III compliant sports utility vehicles (SUVs) in Pakistan.Honda Atlas was the first domestic assembler that had lodged a complaint about the poor quality of petrol marketed by the oil majors in Pakistan towards the end of 2017. Later Oil and Gas Regulatory Authority tested the fuel available in the market and confirmed that oil marketing companies and refineries were adulterating petrol with chemicals to increase the research octane number to meet the regulator’s standards.The presence of a very high level of manganese in petrol being marketed across the country is responsible for choking cars’ catalytic converter, causes engines to knock, and adversely affects environment and human health. The oil marketing companies have since agreed to reduce the ratio of manganese in their products in a phased programme.
