Hatz 1B20 overview

Emission

Environmental aspects

At Hatz, protection of the environment is regarded as a key component of the company objectives. For example, the B-series engines have been exclusively produced and marketed for many years in accordance with the specification of the EPA Tier 4 exhaust directive, even in countries where no limits are imposed on exhaust emissions. That is why the engines will fulfill the requirements of EU Stage V as well.


Injection

SCS (Single Cam System)

One of the numerous innovations of the B-series is the single cam system, where the injection pump and the two valves are operated by just one cam and rocker arm. This design detail, for which Hatz has applied for a patent, substantially determines the very short overall length of the engine. In addition, the camshaft is driven via a gear wheel which is, at the same time, a component and drive of the oil pump.
