THERMODYNAMIC ANALYSIS OF THE CONROD-FREE ENGINE

The paper considers the problems related with the thermodynamic analysis of the conrod-free engine. A mathematical model of the intake system of the conrod-free engine is proposed, which takes into account the kinematics of the slider-crank mechanism. The computational model of the intake system of the engine with the slidercrank mechanism is presented. The model allowed determining dependencies of the mixture temperature in the intake pipeline on the rotation frequency of crankshaft and on the

RESEARCH OF ROTARY PISTON ENGINE USE IN TRANSPORT POWER PLANTS

A schematic diagram of a transport hybrid power plant using a new design RPE-4.4/1.75 rotary piston air engine is proposed. Its external speed characteristic is determined, according to which the maximum engine power is 8.75 kW at 850 rpm and the maximum torque is 127.54 N∙m at 400 rpm. For various gears and speeds, all the components of the power balance were determined and the dynamic characteristic of the hybrid car was obtained when operated on an air engine. According to the dependences of

ANALYSIS AND VALIDATION OF THE DYNAMIC METHOD FOR DIAGNOSING DIESEL ENGINE CONNECTING ROD BEARINGS

The paper considers the problems related with diagnosing diesel engine crank gears, and presents most widely used methods for their diagnosis. The authors provide arguments in favour of dynamic health status identification of connecting-rod bearings in terms of the oil layer thickness. For the first time the dependence is obtained of the oil layer thickness in conrod bearings from the rotation frequency of the crankshaft and the pressure in the lubrication system.

EMISSIONS FROM A MEDIUM-DUTY CRDI ENGINE FUELLED WITH DIESEL–BIODIESEL BLENDS

In the present work, biofuels produced from different raw fatty materials have been proposed as a dominant fuel component in biodiesel–diesel fuel blends. Biofuels were produced from pork lard and rapeseed oil by alkali transesterification using methyl alcohol. Blends of biofuels in volumetric proportions of 60 and 80% of the biocomponent and the remaining part of the conventional fuel were used in a compression ignition engine designed for medium-duty vehicles. The experiments were

ENERGY CONSUMPTION AND CARBON FOOTPRINT OF AN ELECTRIC VEHICLE AND A VEHICLE WITH AN INTERNAL COMBUSTION ENGINE

The use of electrically powered vehicles is becoming more and more established in practice and represents a promising solution in future ensuring quality mobility and reducing the pollution in the environment. Since these vehicles are high-priced, and there is still a low awareness among consumers in terms of energy consumption and pollution, vehicles with an internal combustion engine remain the norm. For this purpose, the study, here, provides an energy consumption estimate of an electric
