As of January 2014, the sale of the newly developed four-cylinder engine 4H50TIC starts. The 2 litre diesel engine is equipped with the latest Bosch common-rail technology, turbocharger, exhaust gas recirculation (EGR) and an oxidation catalyst. The extremely low emission values, the performance and fuel efficiency set benchmarks in the 50-75 hp class. In the development of the 4H50TIC, a ground-breaking downsizing approach was pursued. The primary development objectives were to reduce size and weight while maintaining a high performance and excellent exhaust gas values. The result is a turbocharged 2 litre engine that achieves a maximum output of 74 hp and weighs just 173 kg. This represents the benchmark in its performance class. It goes without saying, that the engine fulfills the strict EU 97/68 Stage IIIB and EPA Tier 4 final limits. The exhaust after-treatment requires just a robust diesel oxidation catalyst (DOC), which in contrast to a diesel particulate filter (DPF) is maintenance-free and built for a lifetime. Furthermore, the DOC works without any electronics. The use of a diesel particulate filter is not necessary due to the reduction in the particulate matters (PM) already during the combustion process, but can be adapted as an option based on regional and local requirements. The 4H50TIC has numerous application possibilities and can be divided into three areas: mobile devices, machines and stationary machines, various application areas that require a compact and powerful engine. The 4H50TIC is the first engine of a new H-series. A 3-cylinder version is already in development and will, depending on the launch of the next stage of emissions legislation, come onto the market from 2016 onwards.
