Exhaust Gas Recirculation is an effective method for NOx control. The exhaust gases mainly consist of carbon dioxide, nitrogen, etc. and the mixture has higher specific heat compared to atmospheric air. Re-circulated exhaust gas displaces fresh air entering the combustion chamber with carbon dioxide and water vapor present in engine exhaust. As a consequence of this air displacement, lower amount of oxygen in the intake mixture is available for combustion. Reduced oxygen available for combustion lowers the effective air–fuel ratio. This effective reduction in air–fuel ratio affects exhaust emissions

PRESENTATION ON FOUR WHEEL COUNTER STEERING MECHANISMmohammedhusain541
The four-wheel counter-steering mechanism, also known as "quad steering," is an advanced steering system designed to enhance maneuverability, stability, and control in vehicles. Here's a detailed description of its presentation:
1. **Introduction to Quad Steering**: Begin by introducing the concept of four-wheel counter-steering, explaining that it involves the coordination of all four wheels to steer the vehicle in a more precise and controlled manner.
2. **Components and Operation**: Describe the key components of the system, including sensors, actuators, control units, and the steering mechanism itself. Explain how these components work together to enable four-wheel counter-steering.
3. **Steering Algorithm**: Discuss the algorithm used by the system to calculate the optimal steering angles for each wheel based on inputs such as vehicle speed, steering input, road conditions, and driving dynamics. Highlight the role of advanced control algorithms in ensuring smooth and responsive steering.
4. **Benefits of Quad Steering**:
- **Enhanced Maneuverability**: Explain how four-wheel counter-steering allows for tighter turns and improved agility, making it easier to navigate through tight spaces and corners.
- **Increased Stability**: Discuss how the system enhances vehicle stability by actively correcting oversteer and understeer, reducing the risk of skidding or loss of control.
- **Improved Safety**: Emphasize the safety benefits of quad steering, such as reduced risk of rollovers and enhanced stability in emergency maneuvers.
- **Comfort and Convenience**: Highlight how the system improves driver comfort by reducing the effort required for steering, especially at low speeds or when parking.
5. **Application and Implementation**: Provide examples of vehicles or automotive brands that have implemented four-wheel counter-steering technology in their vehicles. Discuss any specific features or innovations unique to each implementation.
6. **Challenges and Considerations**: Address any challenges or limitations associated with quad steering, such as cost, complexity, and potential reliability issues. Discuss how manufacturers are addressing these challenges to make the technology more accessible and reliable.
7. **Future Developments**: Offer insights into future developments and advancements in quad steering technology, such as integration with autonomous driving systems, improved sensor technology, and enhanced performance capabilities.
8. **Conclusion**: Summarize the key points discussed in the presentation, emphasizing the importance of four-wheel counter-steering in improving vehicle performance, safety, and driver experience. Encourage further exploration and adoption of this innovative technology in the automotive industry.

Internal combustion (ic) engines.
An internal combustion engine (ICE) is a heat engine where the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit.
In the existing automobile market which is growing, the competition for better automobile in climbing up enormously. The racing fans involved will surely know the importance of a good brake system not only for safety but also for staying competitive in every race though Brake is the key factor for safety. Braking is a process which converts the kinetic energy of the automobile into mechanical energy for arresting the rotation of the road wheels which must be dissipated in the form of heat.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

3. What is HCCI Engine?
• HCCI is a form of internal combustion in
which the Homogeneous Charge is
compressed to the point of auto ignition.
• HCCI incorporates the best features of both
spark ignition (SI) and compression ignition
(CI)
• As in an SI engine, the charge is well mixed,
which minimizes particulate emissions.
• As in a CI engine, the charge is compression
ignited and has no throttling losses, which
leads to high efficiency.
Fig. 1: SI and HCCI Engine
4. Need of HCCI Engine
• Develop a means to reduce unwanted emissions that
come from Internal Combustion Engines (ICE) And
increase fuel economy.
• To reduce from exhaust of engine
Unburned Hydrocarbons
Carbon Monoxide
Nitrogen Oxides
Particulates ( Soot )

5. Working Principle
HCCI is characterized by the fact that the fuel and air
are mixed before combustion starts and the mixture
auto-ignites as a result of the temperature increase in
the compression stroke
Optical diagnostics research shows that HCCI
combustion initiates simultaneously at multiple sites
within the combustion chamber and that there is no
flame propagation.
