Bosch DI-Motronic: direct-injection technology for cost-effective and environmentally friendly gasoline Automakers are increasingly choosing gasoline direct injection engines minimization reduces fuel consumption and emissions Potential in terms of future emissions standards current generation gasoline direct injection systems, Bosch makes engines more fuel efficient and environmentally friendly. Thus, the DI-Motronic system optimizes the cooking fuel mixture and significantly reduces emissions of carbon dioxide (CO2), hydrocarbons (HC) and oxides of nitrogen (NOx). This allows for the highest standards of emissions, including American Standard SULEV (Super Ultra Low Emission Vehicle). In conjunction with the concepts of minimization DI-Motronic engine has the potential to reduce emissions to a level consistent with environmental standards of the future. Reducing fuel consumption by 15% despite the fact that about two-thirds of cars in the world are still equipped with gasoline engines with intake manifold, direct-injection technology is fast gaining popularity amongst automakers. Thus, a number of companies are now equipping a model system with powerful engines Bosch DI-Motronic. In Europe in the number of such companies include the Volkswagen Group and BMW Mini (in cooperation with Peugeot), in the U.S.
– Ford, establishing a DI-Motronic for six-cylinder engines in the program EcoBoost. According to forecasts of Bosch, in 2016 the share of cars with gasoline direct injection on the world market triple to 16%. Especially new technology quickly spread into Western Europe, North America, Japan and Korea. One of the factors of its success lies in the fact that a combination of gasoline direct injection and turbocharging allows you to implement the concept of minimizing engine. Currently, one of the main directions of development of automotive technologies associated with the minimization of gasoline – that is, with a decrease in displacement, and and number of cylinders is often aimed at reducing fuel consumption and emissions of CO2. Modular system valves and turbocharger to the exhaust increases torque at low revs, so reducing the amount not effect on engine power.
Minimization requires the use of direct injection systems, such as Bosch DI-Motronic, in combination with turbocharging and helps reduce fuel consumption and CO2 emissions by more than 15% compared to engines intake manifold. Solenoid valves for the homogeneous mixing DI-Motronic ideally provides the combustion with the formation of stratified lean mixture, and compression ignition of a homogeneous mixture. The main contribution to the optimization of combustion and fuel economy makes a high-pressure injector with electromagnetic control HDEV5. Depending on the application, the injector injection scheme supports up to seven jets fuel pressures up to 200 bar. Among the main components of the DI-Motronic – high-pressure pump HDP5, featuring compact dimensions and low weight. All components of the fuel system made of stainless steel, which allows use almost any fuel type and quality found in different regions of the world. Piezo injectors with a jet controlled combustion of lean HDEV4 work with injection pressures up to 200 bar and provides ultra-fast multi-stage fuel injection control. This innovative product was first used for standard equipment model Mercedes CLS 350 CGI in 2006
