At the start of the 1970s, Gutmann's development of fuel injection systems marked a major technological leap forward. Throughout the 1980s, Gutmann Messtechnik worked intensively on exhaust emission. This groundwork proved a boom to today's flourishing engine diagnosis and exhaust-emissions-analysis equipment division.
