Motor Sports

Automotive and motorcycle sports are motor sports in which various vehicles (serial and modified cars, motorcycles, buggies, jeeps, trucks, prototypes, etc.) compete with engines of different types (electric motors, hybrid and mostly thermal internal combustion engines - piston and partly rotary). Interest in the discuss sport are progressively increases in the years from people of different age groups. The article comments on environmental issues related to these sports and environmental recommendations for their application. The combined efforts of various institutions are needed to increase the popularity and awareness of sport that can be realized under optimal environmental conditions and does not impair its environmental sustainability. This requires an actual environmental policy and education aimed at future development in this direction.

Ignition And Combustion

Plasma-assisted ignition and combustion, widely applied in gas turbines, scramjets, and internal combustion engines, has been considered as a promising technique in shortening ignition delay time, improving combustion energy efficiency, and reducing emission. Nonequilibrium plasma can excite the gas molecules to higher energy states, directly dissociate or ionize the molecules and, thereby, has the potential to produce reactive species at residence time and location in a combustible mixture and then to efficiently accelerate the overall pyrolysis, oxidation, and ignition. Previous studies have demonstrated the effectiveness of plasma-assisted combustion by using direct current, alternating currant, microwave, radio frequency, and pulsed nanosecond discharge (NSD). Due to the complicated interaction between plasma and combustion in different types of plasma, detailed plasma-combustion chemistry is still not well understood.

Natural Wind

The response of vehicles to the transient forces associated with gusting of the natural wind is assuming greater prominence. Total reliance upon natural gusts is unsatisfactory since these are unpredictable and unrepeatable. Major Continental manufacturers have for several years utilized gusts produced by multiple-fan installations, the power source being either electric motors or internal-combustion engines. The M.I.R.A. equipment is centred on a single Rolls-Royce Avon gas-turbine engine, the exhaust gases from which are directed across a roadway. Measurements have indicated that the gust profiles are similar to those encountered on motorways in respect of rise-time.

To Come

For many decades to come, and in the foreseeable future, internal combustion engines – in many cases with electric motors – will be with us, just like the liquid fuels they require. The importance of crude oil will decline, as these fuels will be increasingly produced on a synthetic basis without CO2 emissions. The answers to the question ”Future Mobility without Internal Combustion Engines and Fuels?“ are “no” in both cases. Purely battery-electric mobility will be applied in the future only in specific areas. Fuel-cell vehicles will hardly be used because of the extreme infrastructure investment costs. In contrast, liquid fuels will ensure the future of mobility. In this scenario, energy such as solar or wind energy will be generated without CO2 emissions.

Vibration Problems

The vibrations observed in internal combustion engines transfer to the Tail pipe via exhaust manifold. Such Vibrations cause failure of exhaust system. Two types of vibration can affect the exhaust manifold: the sonic pressure waves coming from the exhaust ports, and the vibration of the engine itself. Pressure wave vibrations are usually transparent, travelling through the exhaust system to either absorb into or cancel out in the muffler. These waves are harmonic, like the vibration of a speaker, but they are usually too minute to cause noise through component movement. Engine vibrations, on the other hand, can easily shake your complete exhaust system. Such cyclic loading of waves can cause component rattling or failure. This vibration failure occurs due to resonant frequencies occurring in defined frequency range. The ‘frequency match’ could lead to a response detrimental to the life of the structure.FEA techniques are proposed in this work to avoid resonance. Physical experimentation is proposed using FFT Analyzer. This work deals with the damping of such later mentioned vibration problems with a concept of CAE (Computer Aided Engineering). In this project we are analyzing the exhaust system under various conditions for modal (natural vibrations). Static and modal analysis of exhaust manifold has been performed using ANSYS 19 software along with experimental validation of manifold using FFT and impact hammer test. Different types of methods for reducing vibration of manifold are studied. After studying these methods and procedures for reducing a vibration, we conclude that, exhaust manifold concept 02 is more efficient by changing the geometry or adding proper stiffener for reducing vertical vibration which further increases the frequency response of component..

The purpose of this study is to identify and analyse the calculation of exhaust gas heat produce (EGHP) in internal combustion engine (ICE) based on three types of fuel used specifically Petrol Ron 95, Petrol Ron 97 and Vpower racing base. The experimental test rig has used 1.6 CamPro Proton engine with 1561cc capacity and dynamometer. The calculation has used the basic formula of heat transfer equation and heat loss through the exhaust that included the mass flow rate of exhaust gas, specific heat of exhaust gas and temperature gradient. The exhaust temperature of ICE is generally in range from 400C to 600C and exhaust gas heat transfer affects the emissions burn-up in the exhaust system. This contributes significantly to the engine requirement. The experimental data was statistically analysed to identify the unknown parameter. High correlation of data variables can be determined based on the heat loss produced or EGHP. This also has significance by using different types of fuel in ICE.

The article proposes a technique for solving applied problems for the preparation of technological processes of mechanical processing on machine tools with numerical programmed control (CNC) of different types of profiled surfaces with the aim of ensuring their further precise connection. In particular, the question of the optimal coverage of the “circle” profile with the common center of these profiles by the “equilateral triangle” profile is investigated. These tasks are relevant in the processing of parts of rotary-piston internal combustion engines, parts of profile joints with equiaxial contour and in other similar technologies. In the work, the value of the function determining the difference of areas, according to which these profiles do not coincide, was obtained, the function was investigated for extremality, two points of its extremum were determined in the domain of definition, it was shown that at one of these points the function acquires a minimum . The conditions for such an extremal coverage of one profile in accordance with another profile are established, figures are given for the formulation and solution of the problem, conclusions are made.

Innovative Solution

This research is aimed at studying the possible advantages of installing, for a hybrid propulsion aircraft, electric motors and related propellers into the dedicated supplementary nacelles. This innovative solution is different from the configuration, already studied for a regional turboprop (Chiesa et al.2013), in which the electric motors are in the same nacelles of the internal combustion engines. As it has been expected, it offers the advantages of avoiding mechanical links between the two units and, more importantly, can also be applied to jet aircraft. In fact, the main contribution of electric motors is expected during ground operations, take-off and descent phases (i.e. at low speed), in which it can be useful to integrate the propellers or even substitute the jet engines with them. At high speed, the propellers, of course, are configured in order to reduce drag. When considering the design of a new airliner concept, a preliminary design study is necessary to optimize the location of the supplementary nacelles. The nacelles, which only hold the electrical motor, can also be considered retractable, as is usual for a RAT (Ram Air Turbine). Please note that in the hybrid propulsion context, the RAT function can be clearly allocated to the electric motor, with the advantages of optimizing drag at high speed, taking into account installation problems.
