Advancements were made to the fuel supply system on the basis of the original X195 Diesel Engine correlating its structure features, and we designed exhausting performance experiments on the injection diesel engine burning the mixture of ethanol and diesel. The results show that: the exhaust smoke and the NOx emission could be significantly reduced by ameliorating the engine.

The results of the investigation of operational reliability of the fuel supply system of diesel engines F1A FIAT DUCATO cars, the main reasons for the system's loss of operability, the numeri-cal characteristics of its failure-free performance are given. On the basis of processing the array of experimental data on faults and failures in the system, the regularities of change of failure intensi-ty and probabilities of failure-free operation of its main parts depending on vehicle mileage are determined. Methods and algorithm of troubleshooting and timely elimination of damages occur-ring in the fuel supply system are proposed and tested at the FIAT PROFESSIONAL dealership in Vladimir. The introduction of the results of the performed investigations into the production pro-cesses of car service enterprises allows to significantly reduce the costs of maintaining the opera-ble state of the diesel engine fuel supply system in operation.

Fuel Supply System

In diesel engines, the combustion process takes place over a very short period of time (0.001 s). As a result, complete and timely combustion of fuel and good use of the air available in the engine cylinders can be achieved only with very high-quality mixing. The use of biofuels in modern diesel engines causes a number of problems associated with changes in the parameters of fuel supply and mixing. All types of fuel have different characteristics: density, viscosity, lubricating properties, self-ignition temperature, compressibility and. in this regard, the laws of fuel supply: spraying, combustion, will be different. The viscosity of biofuels is higher than that of diesel fuel. For this reason, its capacity through small holes in the nozzle of the nozzle (dh= 0.25...0.40 mm) lower than diesel fuel. Due to the small diameter of the holes in the nozzle nozzles and the increased viscosity of biofuels, the nozzle holes are quickly coked. At the same time, the shape and direction of the jet initially changes, and then the hole is completely coked and the fuel supply stops. Thus, for high-quality operation of the diesel engine on biofuels, it is necessary to modernize the design of the mixing and fuel supply system. This problem can be solved by using systems with separate combustion chambers, i.e. using vortex chamber mixing. In the vortex chamber, 60-80% of the fuel burns, the pressure increases and the burning torches of the fuel flow at high speed into the main over-piston plane of the combustion chamber, where there is a significant supply of air that is not used during the combustion of the charge in this chamber. At the same time, oxygen from the air is well used, and the operation of the diesel engine becomes more efficient at relatively low values of the excess air coefficient at the nominal mode and less toxicity of exhaust gases than for single-chamber diesels.
