history of abc

the period 1945-1980

The engine DU completely responded to the requirements and found and covered a new market-segment. Further designs of 5, 6 and 8 cylinder engines took place. As soon as the principle of turbo-charging the engines, leading them to higher power output, was known, ABC adapted his DU engines. The new turbo-charged engines were commercialized under the name DUS. A 50% increase of power from the same engine cylinder-volume was obtained.

A new version from the DU engine-line was designed and the name DX was given to the naturally aspirated version and DXS for the turbo-version. The engine speed was increased from 600 to 750 rpm. Through cooling of the charge-air after the turbo compressor by means of an intercooler, the power of the same engine could be doubled, if compared to the naturally aspirated engine. This family got the name DXC.

The engines can be used for generating electricity as well as for propulsion of ships and as traction engine in locomotives (mostly maneuvering locomotives). Until the end of the sixties ABC knew a prosperous time and exported to all European countries, Central Africa, the Middle and Far East.

In the seventies the management couldn't obtain equilibrium between income and costs. Furthermore the most important market, Belgium Congo, was lost due to the independency fights and the new nation, Zaire having not enough financial means.

A license for a high-speed engine was taken from the French Company Semt-Pielstick in 1973, leading to the production of the PA4 range for in-line engines.

Moreover, the company developed a complete new engine, being the DZC engine with double power from almost the same cylinder-volume. The engine speed was increased to 1000 rpm. Target was to build 100 engines of this type every year. The engine could burn heavy fuel up to 380 cSt.
