Design Example: Automobile Ignition System01:14

Design Example: Automobile Ignition System

389
The automobile's ignition system plays a vital role by ensuring the timely ignition of the fuel-air mixture in each cylinder. This ignition is facilitated by a spark plug, which is composed of two electrodes separated by an air gap. A spark forms across this air gap when a substantial voltage is generated between the electrodes, leading to the ignition of the fuel.
One can generate a large voltage using a car battery of 12 volts with the help of inductors. Inductors are known for opposing...

Internal Combustion Engine01:20

Internal Combustion Engine

2.0K
The internal combustion engine is a heat engine that uses the byproducts of combustion as the working fluid instead of using a heat transfer medium to transfer heat. The combustion is done in a way that produces high-pressure combustion products that can be expanded through a turbine or piston to create work. Internal combustion engines can again be categorized into three kinds: (1) spark ignition gasoline engines, most commonly used in automobiles, (2) compression ignition diesel engines that...

Open and closed-loop control systems01:17

Open and closed-loop control systems

1.2K
Control systems are foundational elements in automation and engineering. They are broadly categorized into open-loop and closed-loop systems. These classifications hinge on the presence or absence of feedback mechanisms, significantly influencing the system's performance, complexity, and application.
An open-loop control system operates without feedback from the output. It consists of two primary elements: the controller and the controlled process. The controller receives an input signal...

Control Systems

1.6K
Control systems are everywhere in contemporary society, influencing diverse applications from aerospace to automated manufacturing. These systems can be found naturally within biological processes, such as blood sugar regulation and heart rate adjustment in response to stress, as well as in man-made systems like elevators and automated vehicles. A control system is essentially a network of subsystems and processes that collaboratively convert specific inputs into desired outputs.

PD Controller: Design01:26

PD Controller: Design

420
In automotive engineering, car suspension systems often employ Proportional Derivative (PD) controllers to enhance performance. PD controllers are utilized to adjust the damping force in response to road conditions. A controller, acting as an amplifier with a constant gain, demonstrates proportional control, with output directly mirroring input.
Designing a continuous-data controller requires selecting and linking components like adders and integrators, which are fundamental in Proportional,...

Multi-input and Multi-variable systems01:22

Multi-input and Multi-variable systems

217
Cruise control systems in cars are designed as multi-input systems to maintain a driver's desired speed while compensating for external disturbances such as changes in terrain. The block diagram for a cruise control system typically includes two main inputs: the desired speed set by the driver and any external disturbances, such as the incline of the road. By adjusting the engine throttle, the system maintains the vehicle's speed as close to the desired value as possible.
In the absence...

  • Artificial Intelligence

Background:

  • Urbanization and increased vehicle use lead to traffic congestion, causing fuel waste and pollution.
  • Engine start-stop technology is widely adopted to mitigate these issues but suffers from frequent, mistaken triggers.
  • Current systems often reduce user driving experience, leading to system deactivation.

Purpose of the Study:

  • To develop an intelligent engine start-stop trigger (IEST) system.
  • To address deficiencies in current start-stop technology, such as mistaken triggering and frequent engine cycling.
  • To improve the driving experience and reduce fuel consumption in congested urban environments.

Main Methods:

  • Established an intelligent engine start-stop trigger (IEST) system.
  • Developed an image recognition model to analyze road conditions.
  • Integrated a digital traffic analysis model to assess real-time traffic status.

Main Results:

  • System tests demonstrated that the IEST effectively avoids frequent engine starting and stopping.
  • The IEST significantly improved the user driving experience.
  • Reduced engine fuel consumption was observed with the implementation of the IEST.
