Below about 40вЏ, certain hydrocarbons in diesel turn gelatinous. The problem is that diesel jells at low temperatures. вЂ‹ вЂњModern diesel engines start in cold weather with very little effort.вЂќ вЂњTodayвЂ™s technologies for cold-start are very effective,вЂќ Ciatti said. вЂ‹ вЂњIf youвЂ™re buying a diesel car from 2007 or later, itвЂ™s no dirtier than a gasoline-powered vehicle.вЂќ Myth # 2: Diesel engines wonвЂ™t start in the winter. вЂњVisible smoke is essentially gone, as of the 2007- 2010 regulations,вЂќ Ciatti said. This renders a small fuel consumption penalty. While running, a small amount of extra fuel is added to the combustion chambers in the engine the resulting heat and oxygen activate a catalyst in the DPF to burn off the accumulated soot. The smoke, trapped in a ceramic matrix, accumulates until the carвЂ™s computer determines itвЂ™s time to clean it out in a process called a вЂ‹ вЂњregeneration cycle.вЂќ вЂ‹ вЂњThey remove 95-plus percent of the mass of smoke.вЂќ вЂ‹ вЂњDPFs are very effective,вЂќ Ciatti said. They do this by adding a Diesel Particulate Filter ( DPF), which removes visible smoke. This smoke is particulate matter from diesel exhaust: soot and small amounts of other chemicals produced by the engine.Д«ut EPA emissions requirements have significantly tightened, and diesel engines now have to meet the same criteria as gasoline engines.

вЂњWe all have this image of trucks belching out dirty black smoke,вЂќ Ciatti said.
