High Power Output

The continuously increasing performance data of the modern diesel engines as well as the fulfillment of the very restricted emission standards cannot be realized without the aid of the turbocharger. Due to the prevalence of the turbo charged engines the customer’s attitude to the emitted noises has been changed. The customer wishes a high power output, but no longer wants to hear it. Thus the consideration of the noise characteristics during the development work is recently as important as the thermodynamic or durability issues. This paper deals with different turbocharger noises, describes its sources, transmission routes and possibilities of noise reduction.

Engine Type

The necessity of adapting diesel engines to work on vegetable oils is justified. The possibility of using rapeseed oil and its mixtures with petroleum diesel fuel as motor fuels is considered. Experimental studies of fuel injection of small high-speed diesel engine type MD-6 (1 Ch 8,0/7,5)when using diesel oil and rapeseed oil and computational studies of auto-tractor diesel engine type D-245.12 (1 ChN 11/12,5), working on blends of petroleum diesel fuel and rapeseed oil. When switching autotractor diesel engine from diesel fuel to rapeseed oil in the full-fuel mode, the mass cycle fuel supply increased by 12 %, and in the small-size high-speed diesel engine – by about 27 %. From the point of view of the flow of the working process of these diesel engines, changes in other parameters of the fuel injection process are less significant.
