Turbocharging can provide a cost effective means for increasing the power output and fuel economy of an internal combustion engine. A turbocharger added to an internal combustion engine consists of a coupled turbine and compressor. Currently, turbocharging is common in multi-cylinder engines, but it is not commonly used on single-cylinder engines due to the phase mismatch between the exhaust stroke (when the turbocharger is powered) and the intake stroke (when the engine intakes the compressed air). The proposed method adds an air capacitor, an additional volume in series with the intake manifold, between the turbocharger compressor and the engine intake, to buffer the output from the turbocharger compressor and deliver pressurized air during the intake stroke. This research builds on previous work where it was shown experimentally that a power gain of 29% was achievable and that analytically a power gain of 40–60% was possible using a turbocharger and air capacitor system. The goal of this study is to further analyze the commercial viability of this technology by analyzing the effect of air capacitor turbocharging on emissions, fuel economy, and power density. An experiment was built and conducted that looked at how air capacitor sizing affected emissions, fuel economy, and the equivalence ratio. The experimental data was then used to calibrate a computational model built in Ricardo Wave. Finally this model was used to evaluate strategies to further improve the performance of a single cylinder diesel turbocharged engine with an air capacitor.

The Mathematical Model

According to the results of the study numeric val-ues of influence dynamics of the excess air factor on fuel consumption by diesel internal combustion engine have been received. Cause and effect relationships between the excess air factor and formation of a mix have been defined, optimum intervals of the excess air factor, temperature and air pressure in an intake mani-fold which provide optimum fuel consumption have been given. The mathematical model of fuel consumption de-pending on the excess air factor has been introduced. Studies carried out at the department "Operation of motor vehicles" of the Tyumen Industrial University show that the heating of air in an intake manifold of internal combustion engine KAMAZ 740 up to +67C the temperature interval of the minimum fuel ≤ 2,05 that gives fuel economy consumption increases from-25 to + 77 ° C when to 30 %, especially, at cars opera-tion in severe climatic conditions.

Efficient Combustion

The internal combustion engine manifold has a subsystem that supplies the fresh A/F mixture to the engine cylinders where the fuel is combusted. For efficient combustion of charge, the walls of the intake manifold must be smooth / polished to minimize any side resistance. To redesign the inlet port of a small internal combustion engine, to increase the production of turbulence by a swirl. A good swirl promotes more rapid combustion and improves efficiency. The CI engine has a piston shaped flat on the crown and a concave combustion chamber, with this geometry we are driving the engine. But here the A/F ratio mixture cannot mix properly. To avoid this we make piston geometry changes. The main objective of this project is that three new technologies have been adopted here. The first stage is varying the diameter of the convergence - the divergent nozzle. The second stage is the change on the piston head and the last stage is replacing the inlet and exhaust valve with pitch 0.5. Mm to 2 mm and the cut thread depth is 4 mm and three threads per inch. All of these techniques aim to investigate performance techniques to increase air flow to achieve improved engine performance and emissions in direct injection (DI) single cylinder diesel engines. Compared with traditional engine.
