Internal combustion engine

Automotive

Whereas in the past the trend was more towards naturally aspirated engines with high-rev concepts, in recent years there has been a shift towards downsizing – small engines with turbocharging. Increasingly stringent requirements in terms of fuel consumption and exhaust emissions make modern engine construction a challenge at all levels.

Lightweight construction, reduction of friction and low CO2 emissions have top priority. In order to achieve these requirements, the highest demands are placed on production. As a result, the already tight specifications regarding shape and position tolerances as well as surface qualities are usually narrowed down even further.

Camshaft and crankshaft grinding

The grinding of camshafts and crankshafts places very high demands on grinding wheels. Changing operation and movement conditions in the contact zone makes the feeding in of the cooling lubricant very difficult.

Engine turbocharging

Engine turbocharging increases the performance of internal combustion engines. The current trend towards ‘downsizing’ – small engine capacity and few cylinders – makes supercharging by means of a turbocharger an attractive option again.

Injection technology

Injection technology plays a key role in today’s engine construction. In recent years, tremendous advances have been made in terms of reduced fuel consumption and emissions reduction.

Valve train components

Valve train components for valve actuators play a role in engine timing and determine the supply of fresh gas and the removal of old gas. These are generally components for series and mass production.
