INTRODUCTION

Currently, technology has advanced at a pace and Therefore, as technology improves, it will bring an improvement in the automotive industry as well. As technology has come a whole new world, and each year something new and different.

Recent advances in robotics and GPS technologies. All you need do is tell the car where you want to go and the car does the rest. Much research is complete this technology is ongoing and it may be too long before people become drivers of the past.

What is automotive engineering?automotive engineering, is a branch of engineering, incorporating elements of mechanical, electrical, electronic, software and safety engineering as applied to the design, manufacture and operation of motorcycles, automobiles, buses and trucks and their respective engineering subsystems.

Aerodynamically design vehicle

Modern engine designing

1. Fuel Efficient Engine Designs2. Low compression diesel.3. ATFT Technology Engine

About 60% of pollution is created by automobile emissions. In order to

combat climate change there must be reduction in pollution, increase in

efficiency can be obtain by designing better engines.

The performance can be increase by employing the below mentioned

design

Fuel Efficient Engine Designs

Simplicity of the Yoke-Arm for Such Large Performance Benefits

This new arrangement uses a unique yoke-arm which substantially increases piston dwell during combustion to significantly increase combustion efficiencies.

This modification decreases piston rod angularity and the associated piston friction.

Low compression diesel

The pistons modified to carry a chemical charge that initiates combustion from one cycle to the next.

Eliminate the need for spark plugs.

Low compression engine, typically used for burning gasoline, can be designed to burn either a lighter alcohol fuel like ethanol, or a heavier fuel like (bio)diesel.

It can increase the efficiency at least 25%.

ATFT Technology Engine

Advance Tumble Flow Induction Technology is the process by virtue of which fuel air mixture can be burnt completely inside the combustion chamber. 

ATFT tech was introduced by one of the auto legend Hero Honda.

Tumble flow means an air flow circulating in the direction of the cylinder axis.

Proper Ignition of fuel VVT-I

VVT-i means the Variable Valve timing -ignition system.

It basically means that in addition to electronic control over fuel injection and spark timing.

the engine has control over the times the intake/exhaust valves open and close.

Vvt-i engine is designed to consume less fuel compared to non-vvt-i engine

Continuously Variable TransmissionA continuously variable transmission is an automatic that can select any desired drive ratio within its operating range.

CVT can provide better fuel economy.

a CVT does not strictly require the presence of a clutch.

A Chain-driven CVT

For safety the below safety features is add in automotive design present days: (a) Pre Crash System (b) Air Bags (c) Antilock Brake System (d) Global Positioning System

Airbag

ABS System

Conclusion

The modern features in automobiles have made automobile step up to the design of Ultimate vehicles. The various safety feature have made the vehicles more safe and comfortable.This makes the journey comfortable and safe. In future more evolution will make the vehicle ultimate.
