Laboratory of propulsion units
The department conducts research and development of ecological propulsion units with optimized transmission and energy conversion for transport, mobile machinery and energy equipment. Research and development is being conducted mostly with industrial partners in terms of contractual research or national grants.
New research directions
- New solutions and optimization of current concepts of propulsion units for transport, working machinery and energy equipment with low production and operating costs, which will be based both on classic as well as hybrid arrangements of highly efficient piston engines burning renewable fuel or fuel cells, and drive motors.
- Use of alternative fuels for internal combustion engines, use of new fuels produced from renewable energy sources, development of gas engines.
- Optimization of the combustion process and reduction of exhaust emissions.
- New concepts of connecting distributed resources of mechanical and electrical energy and controlling their flow.
- Research and development of automobile chassis drivelines, inter-axel clutches and differentials, efficiency of fixed gears and gearboxes.
Experimental research and development of propulsion units for transport and industry focused on the optimization of:
- Economic and emission properties of gasoline and diesel engines, gaseous (classical and alternative) fuels and their mixtures (gasoline, diesel, LPG, CNG, hydrogen, methyl oils, methanol, ethanol) for drive units in transportation, working machinery and energy equipment.
- Drivelines for power transmission in classic and hybrid arrangements of combustion engines, electric motors, fuel cells, batteries, electrolyzers and vehicle wheels or drives of industrial machines and energetic equipment.
- Accessories: in particular common rail injectors for gaseous and liquid fuel, elements to reduce the passive resistance of engines and transmissions, vehicle directional control systems, etc.
New hybrid drive systems for mobile and stationary equipment complying with future EU6 emission limits and limits on greenhouse gases, with an emphasis on the use of new types of fuel from renewable sources.
- Powertrain test bed – the equipment is used for experiments during research into the reduction of fuel consumption in transport and industry through the optimization of power transmission e.g. by using hybrid systems. This equipment serves to measure the forces between the drive unit and the final utilizable power output and identification of the efficiency of individual parts of transmission systems.
- FTIR spectrometer – the equipment is used to measure various components of gaseous emissions (including ammonia, methane, aldehydes and organic compounds) from new internal combustion engine technologies and fuels.
The laboratory also uses these technologies:
- Four motor testing rooms with dynamometrs and emission analysers.
- The laboratory is also equipped with equipment for visualizing the processes that take place inside a combustion chamber – VISIOSCOPE and an INDIMETR instrument for measuring dynamic combustion pressure.
- Research and development of spark ignition engines (gasoline, gas, alternative fuel) and diesel engines for cars and heavy vehicles.
- Long-term engine testing in our own laboratory (water, eddycurrent and electric dynamometers), cooperation in the supervision of tests at the client’s workplace.
- Visualization and calculation of admixture formations, combustion processes and exhaust emissions.
- Experimental research of common rail injectors for gaseous and liquid fuels.
Measurement of particle size in the most problematic size categories from single units to hundreds of nanometers.
- Measurement of the passive resistance of engines and transmissions.
- Measurement of inertia of solids.
- Strength and deformation analysis of engine and vehicle parts.
