A micro cogeneration unit based on a three-cylinder internal combustion engine, Skoda MPI 1.0 L compressed natural gas (CNG), with an output of 25 kW at 3000 RPM is proposed in this paper. It is a relatively simple engine, which is already adopted by the manufacturer to operate on CNG. The engine life and design correspond to the original purpose of use in the vehicle. A detailed dynamic model was created in the GT-SUITE environment and implemented into an energy balance model that includes its internal combustion engine, heat exchangers, generator, battery storage, and water storage tank. The 1D internal combustion engine model provides us with information on engine start-up time, actual effective power, friction power, and the amount of heat going to the cooling system and exhaust pipe. The catalytic converter was removed from the exhaust pipe, and the engine was always operating at full load; thus, engine power control is not considered. An energy storage system for an island operation of the entire power unit for a large, detached house was designed to withstand accumulated energy for a few days in the case of a breakout. To reach a low initial system cost, the possible implementation of worn-out battery packs toward emission reduction in terms of the second life of the battery is proposed. The energy and emission balance are carried out, and the service life of the engine is also discussed.

Mechanical And Tribological Properties

The piston of the internal combustion engine is one of the most complex parts among all engine components. During the operation, the pistons of IC engines are typically subjected to high loading and wearing. To withstand these, they require high mechanical properties and excellent tribological properties. This chapter aims to compare the mechanical as well as tribological properties of silica-gel-reinforced aluminium composite with aluminium alloy, which is used in manufacturing of piston of IC engine. Initially silica-gel-reinforced aluminium composite was fabricated with base material aluminium and six different percentages of silica gel reinforcement by stir casting method. After that, mechanical and tribological properties of silica-gel-reinforced aluminium composite were estimated and the tremendous mechanical and tribological properties among all percentages by different optimization techniques were found. The authors then compared the admirable properties of aluminium composite with aluminium alloy for manufacturing of piston of IC engine.

Production Of Hydrogen

The production of hydrogen with the exhaust energy of an internal combustion engine was investigated in this paper. Steam reforming of methanol is an efficient way to generate hydrogen at relatively low temperature. The reactants of this process are methanol and water, and the hydrogen yield may reach as high as 75% theoretically. However, this is an endothermic reaction, and additional energy has to be provided to this process. If copper oxides and zinc oxides are used as catalyst, the reaction may proceed at the temperature of 270°C. A heat exchanger was designed in this study to use the hot exhaust of a diesel engine to convert methanol to hydrogen. This system is composed of a reformer, a heating chamber, a by-pass valve, and a control valve. Methanol was mixed with pure water at the ratio of 1:1 to form methanol solution. The flow rate of the methanol solution was adjusted according to the engine speed and load such that the thermal energy of engine exhaust may be fully utilized. The reformer is made of copper tubes and compact alumina fins. Pills of catalyst were filled inside copper tubes. Hot exhaust gas flowed through fins and transferred heat to methanol solution. Methanol solution at room temperature was fed into the reformer at a specified rate. It was heated and vaporized inside the copper tube, and then converted to the final products. It was found that in our system the molar fraction of H2 in the reformed gas was 72.6%, while that of CO2 was 23.5%. The exhaust temperature of a diesel engine varies in the range of 250°C~450°C, depending on the load of engine. It is quite sufficient to generate hydrogen with engine exhaust in a methanol reformer. In our system, the hydrogen rate of 17.3 L/min can be obtained in the exhaust pipe of a diesel engine with the displacement volume of 6000c.c. It was found that 49.5% of thermal energy can be recovered, and 92.6% of the recovered energy can be converted. In total, 36.7% of the waste energy can be recovered and stored in the reformed fuel.

Opening And Closing

The use of generators at different load levels allows you to use part of the rated power of the engines, by reducing the speed of the internal combustion engine, thus reducing fuel consumption and increase the overall efficiency of the system as a whole. However, it should be noted that the optimal operation of the internal combustion engine at fixed gas distribution parameters is possible only at a certain engine speed. Reducing the engine speed leads to a deterioration of the filling of the fuel-air mixture and the release of exhaust gases from the engine, accompanied by the intake of exhaust gases into the intake manifold and the emission of part of the fuel mixture into the exhaust pipe. The paper presents the results of the study of generator parameters and the general concept of creating an autonomous power supply control system based on an internal combustion engine in order to reduce the specific indicators of electricity generation. The expediency of regulating the power level of an internal combustion engine has been experimentally proved. To achieve this goal, it is proposed to adjust the opening and closing angles of the internal combustion engine with a solenoid valve. The use of this system allows to reduce the specific costs by more than 4 times when generating electricity with low generator load. Based on the phase distribution diagram of the internal combustion engine, the dependence of the change of the opening and closing angles of the inlet and outlet valves on the power of the autonomous energy source is proposed.
