So, the diesel engine, principal drawback is, their emission of air pollutants.
Because, these engines typically discharge, high levels of particulate matter (soot).
That’s why, in the small engine category, consumer acceptance is low.
However, the diesel engine, is the most versatile fuel-burning engines in common use today.
Furthermore, compared to gasoline engines, they’re simpler, more efficient, economical and safer. Consequently, diesel fuel is, less volatile and its vapor, less explosive than gasoline.
Unlike gasoline engines, they’re particularly good for, moving large loads at low speeds. So, they’re ideal for use in freight-hauling ships, trucks, buses, and locomotives. Higher compression means, the parts of a diesel engine have to withstand, far greater stresses and strains, than those in a gasoline engine.
One big difference is that diesels have a compression-ignited injection system, rather than the spark-ignited system used by most gasoline vehicles.
In a compression-ignited system, the diesel fuel is injected into the combustion chamber of the engine and ignited by the high temperatures, achieved when the gas is compressed by the engine piston.
That’s why they need to be stronger and heavier and why, for a long time, they were used only to power large vehicles and machines. While this may seem like a drawback, it means diesels are typically, more robust and last a lot longer, than gasoline engines.
So, the diesel engine is, an intermittent combustion piston cylinder device. It operates on either, a two stroke or four stroke cycle. However, the engine induces, only air into the combustion chamber, on its intake stroke. Engines with bores of greater than 600 mm, are almost exclusively, two stroke cycle systems.
No one knows for sure but, there is talk of them being phased out, by the year 2030. What can replace them and where will the power come from. One time will tell.
