ABC is manufacturing diesel engines since 1912. The company has the reputation of building robust and simple engines, with low fuel and lubricating oil consumption, long lifetime, low maintenance cost and easy accessibility. Both engine types have been adapted for dual-fuel (diesel-gas) combustion. The DX-engines are also available as spark ignited engine. Our work-shop in Gent is among the most modern in the world, using the newest types of automatic, numerical controlled machine tools. Strong and cost-efficient engines are a vital necessity. ABC has concentrated on extensive research and development, which enables the company to produce one of the most reliable engines in the world. This self set goal for quality and reliability requires high investments in quality control during all stages of production. Therefore, apart from the traditional test-benches, N.C. equipment was installed providing a complete "coordinated measuring center". This measuring center guarantees a full scale geometrical precision of the finished product.
