In Passenger Cars, The Diesel Engine Has Never Reallycaught On. During The Middle To Late 70s, Dieselengines In Passenger Cars Did Notice A Surge In Sales Due To The OPEC Oil Embargo, Although That Isthe Only Real Significant Penetration That Dieselengines Have Made In The Market. Although Diesel Engines Are More Efficient, Thereare Eight Historical Problems That May Have Held Them Back.1. Due To The Higher Compression Ratios, Diesel Engines Tend Be Heavier Than The Equivalentgasoline Engine.2. Diesel Vehicles And Diesel Engines Tend Tobe More Expensive Than Gas.3. Because Of Their Weight And Compressionratio, Diesel Engines Tend To Have Lower RPM Rangesthan Gas Engines. This Gives Diesel Engines Moretorque Rather Than Higher Horsepower, And This Tendsto Make Diesel Vehicles Slower In Terms Of Acceleration.4. Diesel Engines Have To Be Fuel Injected,and In The Past Fuel Injection Was Very Expensive And Less Reliable.5. Diesel Engines Tend To Produce More Smoke And Smell Very Funny When Compared To Gasolineengines.6. They Are Harder To Start In Cold Weatherand If They Contain Glow Plugs, The Diesel Enginesmay Require You To Wait Before You Start The Engine So That The Glow Plugs Can Heat Up.7. Diesel Engines Are Much Noisier Than Gas Engines And Tend To Vibrate Quite A Bit.8. Diesel Fuel Is Less Available Than Gas.Although One Or Two Of These Disadvantages Would Beacceptable, A Group Of Them Is A Big Turn Away Formany People.Even Though The List Above Are Reasons In The Pastas To Why Diesel Never Really Took Off, You Can Expect These Reasons To Get Corrected And Improvedin The Future, Meaning That You Will See More Andmore Diesel Vehicles On The Road.(word Count 301)PPPPP
