COMPRESSED AIR, THERMAL AND DYNAMIC CALCULATION, ELECTROMAGNET, INJECTOR, 4B10 ENGINE, SAFETY AND ENVIRONMENTAL FRIENDLINESS, ECONOMY

The object of the degree design is the 4B10 mitzubish engine. An analysis of the economic activities of TransTehService LLC was carried out, and an ongoing repair site was developed. During the work, based on the analysis of existing structures, the power supply system of the Mitsubishi 4B10 engine was improved, the thermal and dynamic calculation of the engine was carried out, and design documentation for the manufacture of parts was developed. The process of the compressed air power supply system installation has been developed. An assessment of the state of labor safety and safety at the enterprise and at the area of ​ ​ ongoing repair of cars was made.

Introduction

Relevance of the topic. The fuel supply system of the gasoline engine is designed to place and clean the fuel, as well as prepare a combustible mixture of a certain composition and supply it to the cylinders in the required amount in accordance with the engine operating mode.

Engine efficiency, economy, performance indicator depend on the engine power supply system. (environmental safety, manageability, dynamism, stability, smooth running, cross-country ability). In case of improper operation of the power supply system, the engine efficiency will be significantly reduced, which will affect the driving performance of the car. Thus, the power system is one of the important systems of the car, which determines many parameters of the car, and the development of power systems is one of the current areas of development of the automotive industry.

The purpose of the diploma project is to modernize the Mitsubishi 4B10 engine power supply system, which is aimed at improving and improving the characteristics of the car using simple means (without radically changing the design of the car), namely, by supplying compressed air to the cylinders of the engine.

Design Objectives:

Analyze existing power system designs;

Develop a compressed air engine power supply system;

Perform thermal calculation of ICE operating on the upgraded power supply system;

Perform structural calculations of installation elements;

To provide a feasibility study of the decisions taken;

Develop measures for labor protection and environmental friendliness of the project.

Analyzing Existing Constructs

The theme of my diploma project is the modernization of the 4B10 engine power supply system, which solves environmental pollution problems and increases the effective engine power.

In recent years, environmental regulations have been tightened to reduce emissions from internal combustion engines into the atmosphere, but without reducing, and even increasing, the effective power of the engine. In this regard, methods have been developed to reduce emissions while increasing the effective engine power.

2.1.2 Advantages and disadvantages of turbochargers

Engine with turbocompressor less bulky, Engine torque curve with turbocompressor can be better adapted to specific operating conditions. turbocharger, providing increased air supply, compensates for reduction of atmospheric pressure, almost without deterioration of engine characteristics.

A significant drawback of the turbocharger is the "turbo pit." Which prevents the turbocharger from responding to changes in speed modes. When the throttle opening pedal is pressed, there will be a loss of power, this is because the turbine needs time to set the required rotation speed, and also turns on from nominal revolutions, resistance to exhaust gases.

Project Feasibility Study

The diploma project proposes to modernize the power supply system (SP) of the engine of the mitsubisi lancer car with the 4B10 engine.

To determine the technical and economic indicators of the use of the modernized joint venture, we calculate the costs for the implementation of this project, the annual economic effect is achieved by reducing fuel costs, the payback period of capital investments.

The economic effect of using this system is achieved due to item

To determine the cost-effectiveness of introducing design development into production, it is necessary to calculate the cost of production.

Conclusion

In the diploma project, the analysis of the production work of TransTech Service was carried out, according to which it is possible to draw conclusions that the enterprise has a good production base for the modernization and improvement of the services provided, and is well provided with production capacities. However, in recent years, rising fuel prices and restrictions, due to environmental pollution, have forced the ordinary consumer to think about buying a car .

Existing power supply systems were analyzed, advantages and disadvantages of structures were identified.

The result of this diploma project is the modernization of the Mitsubishi 4B10 engine power supply system due to the supply of compressed air to ICE cylinders, aimed at increasing power, economy and environmental friendliness, which is achieved due to more complete combustion of exhaust gases. The developed device allows increasing the excess air ratio to the required value at any engine operation modes, as a result of which the characteristics of the car are improved. Thermal calculation of the engine with compressed air supply was performed to determine its dynamic characteristics.

The economic efficiency of this plant is justified, the profitability of the project is 13%, the payback period is 3.4 years.
