Turbocharged Diesels Need a Mighty Tough Air Filter Keeping the Ait Filter intact Can Be a Chalienge

摘要

Neglecting air filter maintenance on a normal aspirated gas engine can result in poor engine performance, poor fuel economy and high emission output. Neglect the same service on a turbocharged diesel engine and some major engine and turbocharger damage can be incurred. Turbocharged diesel engines have a healthy appetite for air, and they can consume more than just air. When the air filter becomes restricted, the turbo can pull contaminates through the filter media, which is referred to as "dusting." It's not uncommon for a restricted air filter to be pulled from its mounted position in the air box, allowing unfiltered air to enter the engine. In some cases the filter disintegrates and is sucked into the turbo, causing major damage to the turbocharger and engine. Ford and GM have both encountered some challenges with their turbo-diesel air filtration systems, and especially problems resulting from improper service procedures and poor maintenance.
