rgallagher+FollowDiesel Engines’ Secret: No Spark Plugs!Ever wondered why diesel engines don’t need spark plugs? It’s all about the science! Diesel engines use super-compressed air to heat things up so much that the fuel just ignites on its own—no spark needed. Instead, they use glow plugs to help out in cold weather. Plus, that crazy compression means more torque and better fuel economy. No wonder trucks love diesel! Wild, right? #Cars #CarOwnership #DieselEngines12Share
Latoya Bradley+FollowWhen Cummins Diesel Got EGR DramaEver wondered when Cummins diesels started using EGR? The real EGR system didn’t show up in Dodge trucks until mid-2007 with the 6.7L engine—before that, the 5.9L had a sneaky cam trick that kinda did the job, but not really. EGR helps with emissions, but a lot of owners say it just adds headaches (think carbon buildup and reliability issues). No wonder so many folks want to delete it! #Cummins #DieselEngines #CarTalk #TruckLife #AutoFacts #Cars11Share
