Huỳnh Hữu Tài ID: 2182501983 Class: 21DOTQA2 Ho Chi Minh City 12/2023 Acknowledgement e&f Our study about vehicle starting system has been done quite good lately. We would like to thank our teacher for providing us with guidance during our learning process. We have gained a lot of experience about the basic structure of an automobile chassis over the last month. We have been given a chance to work with every system in an automobile starting system and the working experience had been wonderful.
Over the last month, we had the chance to know more about systems in automobiles, types of cars systems, and their working principle. Our internship with you helps us achieve my objective which is to increase my exposure to the automobile industry. This automotive electrical and electronic system project has sparked our interest in my career. We would love to stay in touch, and perhaps talk to you again at the next level of this subject.

xi Sinh viên thực hiện TP. HCM, ngày 06 tháng 03 năm 2023 (Ký và ghi rõ họ tên các thành viên) Giảng viên hướng dẫn (Ký và ghi rõ họ tên) xii Chapter 1: Topic introduction 1. Introduction This section introduces the starting systems that can be found in today’s passenger cars. Of course, many car-derived components and systems can also be found in small commercial vehicles.
Also, larger derivatives, which have much in common, can be found in heavy goods and public service vehicles. We have endeavored to introduce the main starting system types and some areas of technology that can be found within the units. In this chapter, however, we can only hope to introduce the subject of starting system to you. To make up for this brevity, we include references to other material so you can follow up on any particular subject in greater detail.
It is probably worth stating that, in practice, the choice of starting units for a particular vehicle is heavily influenced by what is in production and available. Equally, producing a special starting motor to support a specific model would also be difficult to justify even for a large vehicle manufacturer. Current developments are extremely interesting as technology, particularly electronic control, is very much blurring the distinction between the conventional classes of starting systems. These developments not only make the starting system interesting from an engineering perspective but also create marketing features from an area of the vehicle often hidden from view and largely ignored by the buyer until it causes a problem.
Overall, our group would love to research the starting system based on the Toyota Vios 2018 starting system.2 Definitions The starting system of a Toyota Vios 2018 is a complex system comprised of various components designed to ensure quick and efficient vehicle startup. The system's key components include the starting battery, starter motor, starting control unit, and starting fuse. Other critical components such as the combustion chamber, fuel distribution system, air filter, and transmission system also play crucial roles in enabling safe and efficient engine starting. The starting battery is a lead-acid battery that provides a high current to operate the starter motor, and it is typically located near the engine.
The starter motor, which is responsible for initiating the engine starting process, connects to the starting battery and the engine using various parts. The starting control unit is an electronic module programmed to regulate the starting battery and the starter motor's operations. The starting fuse is a safety component that helps protect the system from malfunctions, short circuits, and damage. 1 During the engine starting process, the driver inserts the key into the ignition and presses the engine start button, sending a signal to the starting control unit to activate the starter motor.
The system's proper operation depends on the battery's state of charge, the starter motor speed, and the engine's status. Should the starting system encounter any issues, the vehicle owner is advised to seek assistance from experienced technicians at an authorized Toyota service center for repair and maintenance.3: Topic objective Analyze the starting system of the Toyota Vios 2018. Build a simple starting system model with a key switch. Analyze some common failures and causes on the starting system.4: Study method - Books and internet sources - Microsoft Word - Power point presentation - Building demonstrate model 2 Chapter 2: Overview of starting system 2.1: Starting system requirement An internal combustion engine requires the following criteria in order to start and continue running.
Combustible mixture Compression stroke A form of Ignition The minimum starting speed (about 100rev/min) In order to produce the first three of these, the minimum starting speed must be achieved. This is where the electric starter comes in. The ability to reach this minimum speed is again dependent on a number of factors. Rated voltage of the starting system.
Lowest possible temperature at which it must still be possible to start the engine. This is known as the starting limit temperature. Engine cranking resistance. In other words, the torque required to crank the engine at its starting limit temperature (including the initial stalled torque).
Voltage drops between the battery and the starter. Starter-to-ring gear ratio. Characteristics of the starter. Minimum cranking speed of the engine at the starting limit temperature.
It is not possible to view the starter as an isolated component within the vehicle electrical system, as Figure 2. The battery in particular is of prime importance. 1: Starting system as part of the complete electrical system Another particularly important consideration in relation to engine starting requirements is the starting limit temperature.2 shows how, as temperature decreases, starter torque also decreases and the torque required to crank the engine to its minimum speed increases. 2: Starter torque and engine cranking torque 4 2.
