In 1878, Rudolf Diesel was attending the Polytechnic High School of Germany (the equivalent of an engineering college) when he learned about the low efficiency of gasoline and steam engines. This disturbing information inspired him to create an engine with a higher efficiency, and he devoted much of his time to developing a "Combustion Power Engine." By 1892 Diesel had obtained a patent for what we now call the diesel engine.
Diesel engines became associated with heavy trucks and slow noisy cars.
But in recent years Diesel engines managed to shed their old slow and noisy image, the became much more popular not only in saloon cars but are showing some interested sports capabilities. Learn how new technologies made diesel engines sharper and quieter.
