The diesel engine burning gasoline? What is this nonsense? Classic diesel engine after refueling, the gasoline into the fuel tanks seized. Not a new engine from Mercedes. Mercedes Benz has developed together with new Ricardo engine combining the advantages of diesel and gasoline engines. This new engine designers aptly named DiesOtto, a word spojenina Diesel and Otto.
When he left in 1877, Nicolaus Otto patented his concept of an internal combustion engine, began a new era of motoring. Together with him he tried to push his idea of another German engineer Ing. Rudolf Diesel. Its engine had several advantages such as higher efficiency, and to burn heavy oil and the construction easier. On the other hand, showed more noise and had a harder course. Over time, the diesel engines, primarily for their efficiency, have become a source of strength for the job. While Otto gasoline engines were cultivated for its operation used to drive the cars. Nowadays, more and more coming to the fore efficiency, and designers have begun to flirt with the idea of the benefits of combination of both principles.
The new unit, called DiesOtto designers, uses regular unleaded gasoline. Its duty cycle is at low loads Diesel and Otto at high speed. This has to combine both principles. Attempts to similar mergers are not new. In the past, many such attempts took place. However, the advantage of the new engine is that it allows the use of standard commercially available gasoline. At the start and at high loads mixture ignited by a spark plug. Just under high speed diesel outpace gasoline engines. By contrast, in steady mode, at low and medium engine speeds, the ignition off and the engine acts as a diesel, without having to ignition plug. Basic advantage of such an engine is then lower power consumption and emissions .
Pilot engine, introduced in 2007 at the Frankfurt Motor Show, Mercedes-Benz four-cylinder petrol engine is a 1.8 liter cylinder capacity. It features a turbocharged, direct injection of fuel into the cylinder and variable valve divorce. There is also a variable compression ratio and hybrid starter, working as a generator of energy. The engine manufacturer's maximum power of 175 kW, while the consumption of around six liters per 100 km mainly due to the high torque of 400 Nm
