Hydraulic Disc Brakes

Hydraulic disc brake uses brake fluid ( Ethylene Glycol HO–CH2CH2–OH) to transfer pressure from controlling mechanism to braking mechanism. It was first used in 1914 for racing cars.It is based on the principle of Pascal Law which states that "The pressure exerted anywhere in a mass of confined liquid is transmitted undiminished in all direction throughout the liquid".

Electronic Fuel Injection system

Emission from the engine has been considered as the vital source of air pollution, as a result, governments of various countries start to demand for a strict emission standard from Automobile companies. To achieve emission targets, companies need to optimize engine designs. As Fuel injection is an important step in the engine, it's too needs to improve.

In this post, we will discuss how the fuel injection system works, why it is required and how we can improve its working to make our engine fuel efficient?

Nitro Powered mini RC Car

We have discussed RC Cars before with electric engine and stirling engine. Today we are going to talk about Nitro Car, which has more similarities with cars we use in our daily life.

So, what is Nitro Car?

In my own simple definition, it is a car which runs on fuel consist of methane, nitro methane and oil.It has small internal combustion engine which gets it spark from glow plug powered by batteries inside a car. For more detailed info you can anytime refer to Wikipedia.

What is Glow Plug?

It is similar to spark plug, a helical wire filament usually made up of platinum, but mostly used in small cars. It gets its spark from batteries, compression heat and catalyst effect of methane and platinum.

Car monitoring System

How many times you heard about car accident caused just because of tire burst or due to break fail?
Have you ever imagined that these accidents not only cause harm to car passengers but also to innocent people on the streets. Even though these accidents are random and can happen with anyone but they can be avoided with the help of modern engineering and technology.

Hydraulic Car Lift

We all have heard about Hydraulic lifts sometime in our life, but some of you may think that how it works or how to build one for ourselves.

Today we are going to discuss about lifting cars using Hydraulics, which is based on Pascal concept.

Why understanding Hydraulics important?
Hydraulics is a topic in applied science and engineering dealing with the mechanical properties of liquids. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the engineering uses of fluid properties.

Flying Cars

A flying car is an aircraft that can also travel along roads. All the working examples have required some manual or automated process of conversion between the two modes of operation.

automatic parallel parking cars

What is an Automatic Car Parking?

Automatic parking is an autonomous car maneuvering from a traffic lane into a parking place to perform parallel parking, perpendicular or angle parking.

What's the importance of this topic? 

Parking is one of the challenging things for humans in Car Driving. Even though, lot of solutions available for smooth and safe driving such as car collision avoidance systems, but very less focus is given to the automatic parking system till recently. Although many cars are now available with this feature such as Toyota Prius, still there is a long way to go.

For Whom :
Mechanical, Electrical, Electronics and Computer Science, almost all branches.

Level: Difficult
It is not an uncomplicated task to build up automatic parking expertise for a car. First of all, the car must be able to sense the surroundings, to find a free parking space and to detect obstacles in the car park.
Secondly, it should have the capability to plan the movement itself from the input of the sensor system.
Lastly, it should be able to go after the premeditated motion sequences and to make sure that a goal position is reached, regardless of noise and errors.

Car Collision Avoidance System

 

A collision avoidance system is a system of sensors that is placed within a car to warn its driver of any dangers that may lie ahead on the road.Ford announces new radar based collision avoidance system.This project idea is for Mechanical , Electronics and Physics students.

Hydrogen powered vehicle

Hydrogen Vehicles use the energy produced by fuel cells. A fuel cell is an electrochemical cell that converts chemical energy from a fuel into electric energy. Electricity is generated from the reaction between fuel supply and an oxidizing agent. This project idea is for mechanical and automobile engineering students.

Electronic Valve Actuator

An actuator is a mechanical device for moving or controlling a mechanism or system. It is operated by a source of energy, usually in the form of an electric current, hydraulic fluid pressure or pneumatic pressure, and converts that energy into some kind of motion. Actuators are used for the automation of industrial valves and can be found in all kinds of technical process plants: they are used in wastewater treatment plants, power plants, and even refineries.

Vacuum and Power Brakes

Vacuum brakes are one of the oldest braking systems that exist. It was first introduced and employed on the trains in the mid-1860s. The simplest way to explain it is that it uses vacuum power to stop the train. These brakes have been improved significantly over the years.

Vacuum or power brakes are used in all most all the railways and modern-day cars. It consists of five major components:

1.Brake Pedal

2.Intake Manifold

3.Seal

4.Hinge and

5.Spring

How Vacuum brake works?

This system has two chambers, one is always filled with a vacuum(first) and the other one has either vacuum or atmospheric air(second). There is a link between two chambers, so a vacuum can transfer from the first chamber to second.

When we push the brake pedals, it opens up the second chamber seal, which allows atmospheric air to enter into the second chamber. This air exerts a lot of pressure on the first chamber filled with a vacuum which eventually pushes the brake fluid and stops the vehicle. I am embedding a very important video which will help you understand exactly how it works.


This project is good for the case study purpose. I am giving you some helpful links below  :

Air powered bike

I get this idea from the Planet Mechanics show of National Geographic Channel. I have embedded a clip of that show below. This project uses a similar concept to air cars because both of them use compressed air as fuel.

Concept :
In this project, we compress gas into a cylinder. Compress air behaves like a spring,. more it gets compressed, more force it generates. We can use this force for doing any mechanical work and most of the pneumatic projects use this concept.

How much it cost?

It would not cost much if you have an old bicycle and one cylinder in a scrap. All the other items such as engine (Which can be unrepairable motor pump  ), pipe, valve are cheap and easily available in the market.


How its work?

It's upon you, how you want to use compressed air energy, but I suggest you use old piston method which was used in steam engines, the only difference is, here we use compressed air to push the piston downwards as shown in Video :

Adaptive braking (ABS)

Details :
It provides a better mechanism for braking and helps biker to control bike effectively. ABS (Anti-lock braking system) generally offers improved vehicle control and decreases stopping distances on dry and slippery surfaces for many drivers; however, on loose surfaces like gravel or snow-covered pavement, ABS can significantly increase braking distance, although still improving vehicle control.

Automobile engineering project ideas

Automobile engineering is a very interesting field and its importance in our life is indisputable. Automobile engineering is a vast field and there are many different types of projects we can do. It ranges from petrol engines to diesel engines, diesel engines to hybrid engines and hybrid engines to completely green technologies. Moreover, as we all know that every new car has its own CPU and Memory and with having them into our cars, ideas are not in scarcity now. I myself got amazed by the new technology-driven innovation in the automobile industry where Tesla, Apple, and Google, all wants to become part of. Experts in the sector already start talking about the next competitors of GM and Ford, which is not going to be Toyota abut the technical companies I mentioned above. Moreover, with news of Lary Page's startup flying car is just around the corner, we can surely say that it is a very exciting time in the automobile industry.
