Soon drop.The faster an engine spins the harder it is to ensure that every single combustion cycle fires right at TDC; this is one reason why non-diesel engines these days all have individual coil packs (for each plug) and some form of electronic/computer controlled ignition.Comparably, Diesel engines don't need electronic ignition systems at all, and they don't have high crankshaft speeds either (an ocean liner diesel will rarely do more than 250 - 300 rpm, if that).Diesel engines are also basically built to generate significant torque from very low vehicle/engine speeds, and they also use a fuel that was designed (back when the only gasoline fuel available was leaded) to facilitate a very high compression ratio.It is a fallacy that Diesel engines are way more efficient than typical modern day gasoline engines. Usually - a decade or so ago - it was the diesel engine's ability to provide significant torque from low vehicle/engine speeds, combined with its ability to support high compression ratios, and also the fact that diesel's were turbocharged; that often provided the perceived efficiency and other advantages over the typical gasoline engine. These days - especially with non-leaded gasoline products that support high compression - typical gasoline engines are not only turbocharged, direct injected and running high compression ratios - but they're also capable of both, greater crankshaft rotational speed bandwidths than diesels and also producing big torque numbers at low crankshaft rotational speeds, too.That hits the same target as several of the unique selling propositions that diesels previously offered.Still, the Diesel motor will enjoy popularity for a while longer as Diesel fuel is slightly cheaper than typical gasoline.Plus, diesel engines; (a) are robust, (b) are relatively simple, (c) they usually run at low speeds [and are therefore torque products and "reasonably" economical/cost effective], (d) they don't
