Abstract

The purpose of this research work is to identify the laws of thermodynamic operation in the theoretical cycles of four-stroke inline piston gasoline internal combustion engines (ICE). The main results: dependence of the thermodynamic operation of the working body of ICE in theoretical cycles of four-stroke inline piston gasoline engines as a function of the angle of rotation of the crankshaft; regularities of uneven generation of positive thermodynamic operation in the theoretical cycle of four-stroke inline one-, two-, three -, five-cylinder piston gasoline ICE; regularities of the alternating character of thermodynamic operation in the theoretical cycles of inline four-stroke one -, two -, three -, four - and five-cylinder gasoline piston ICE; regularities of positive thermodynamic operation during the entire theoretical cycle of four-stroke inline six-and eight-cylinder piston gasoline ICE; conditions for uniform pulsation of thermodynamic operation during the entire theoretical cycle of four-stroke inline piston gasoline ICE - the product of the crankshaft angle by the number of cylinders must be 720o (four-cylinder inline with a crankshaft angle of 180o, six-cylinder inline with a crankshaft angle of 120o, eight-cylinder inline with a crankshaft angle of 90o).

Highlights

Piston internal combustion engines are one of the most common classes of rotational action engines
This approach is quite acceptable in the design of wheeled and tracked vehicles, in which a constant consumption of mechanical work generated by a driven inline piston gasoline internal combustion engine is carried out
When designing process equipment driven by inline piston gasoline internal combustion engines, in which the mechanical work created by the engine is consumed not constantly, but in accordance with some law, in purpose to improve the efficiency of the "internal combustion engine - process machine" system, it is necessary to synchronize the maximum output of mechanical work by the engine with the maximum consumption of mechanical work by technological equipment

Summary

Introduction

Piston internal combustion engines are one of the most common classes of rotational action engines. The review of scientific and technical sources, developed by leading Russian scientific centers energy engineering it is revealed that the theoretical justification of parameters of inline four-stroke piston gasoline internal combustion engines is based on some average per cycle of the thermodynamic parameters of the working body of ICE. This approach is quite acceptable in the design of wheeled and tracked vehicles, in which a constant consumption of mechanical work generated by a driven inline piston gasoline internal combustion engine is carried out. It is necessary to solve a number of the following tasks: development of mathematical models of thermodynamic operation in the working processes of four-stroke inline piston gasoline internal combustion engines; modeling the dependence of thermodynamic operation of four-stroke inline-piston gasoline internal combustion engines (ice): one -, two -, three -, four -, five -, six -, eightcylinder engines on the angle of rotation of the crankshaft during the last two speed rotation in Microsoft Excel
