At the same time the engines were very well-known for their outstanding relia- bility and low fuel consumption. First tests with diesel engines started in 1927,but series production with own devel- oped diesel engines started in 1936: six-cylinder pre-chamber diesel engines with seven main bearings and output of 120 hp (88.8 kW). The marine diesel engines of theSwedish manufacturer are installed in a wide variety of vessels, including inland navigation vessels, coaster and sea- going ships, passenger and authorityships, life boats and trawlers. Today?s product range of the Swedish enginemanufacturer for main and auxiliary drives starts with the 13-liter engine at 323 kW and ends with the 16-liter en-gine with 736 kW (1,000 hp). The speed range of both the engines is between1,500 and 2,300 rpm. For Yanmar the company produces engines with outputs up to 660 kW for pleasure craft. The SCANIA engine philosophy is charac- terized by fundamental factors: A high percentage of equal parts in the two series DI13 & DI16; high reliability; longevity; low fuel consumption; and low emissions. The amount of equal parts, the socalled SCANIA module concept in-cludes, beside others: pistons, cylinder liner, cylinder heads, gaskets, filters and unit-pump elements at the injectiontechnology. The engines fulfill all exist- ing worldwide current emission legisla- tions. Each product, which is intendedfor ship application, passes a specific stringent test program which can runfrom four hours to two days.
