The advent of radial tyres has made the ride safer and pleasurable. These tyres were introduced by Michelin in Europe in 1948. These are the tyres with ply cords radiating at a ninety degree angle from the wheel rim and casing strengthened by dual steel belts. Ply cords are usually made of nylon, rayon, or polyester.

Gradually radial tyres were accepted by many car manufacturers because of the key advantage that they held. Some of the benefits of these tyres are the longer tread life, lower rolling resistance, better steering resistance, and improved fuel efficiency. All these advantages increases the demand of radial tyres in the car industry.

Airbags are flexible envelope that acts as a cushion in case of a car accident. The introduction of this safety feature in 1951 revolutionized the car market, delivering higher standards of safety. It was invented by John W Hetrick who was a former naval engineer.

Further to that a component called ball-in-tube sensor was invented by Allen K Breed for crash detection. In 1971, Ford introduced an experimental fleet of cars with airbags. Then, in 1973 it was made available to general public. 1980s further modified the airbags to what they are today including the side airbags, frontal airbags, and rear airbags. At present almost all car models have airbags fitted to ensure safety of the occupants.

In case of an accident, the installed sensors detect the motion and automatically inflate to prevent the passengers from striking hard objects in the car interiors.

CRDi has redefined the diesel engine technology and made diesel cars as smooth as their petrol counterparts. In recent years, more and more car manufacturers have equipped their diesel cars with the engine as these are believed to reduce exhaust emissions and lower the levels of noise, vibration, and harshness.

The basic components of a CRDi engine are a high pressure pump, rail that contains pressurized reserve of fuel, injectors, and a diesel control unit. It is a type of fuel injection system that uses electronic circuits to control the amount of fuel injected into the engine’s cylinder. Then a high pressure pump is used to transfer the fuel from the cylinder to the common rail, a hallow shaft where the fuel is reserved. This type of fuel transfer results in complete combustion, thereby delivering a cleaner environment.

Keeping pace with the laws of fuel-efficiency and emission norms, the fuel system used in modern cars have changed in recent years. A new system was then introduced to achieve better efficiency.

Fuel injection system is a modern system where the fuel is blended with air in the internal combustion engine. The use of carburetors has been replaced by this innovation. It mainly comprises of a small fuel injector that pumps the high pressure fuel into the combustion engine. In order to inject the correct amount of fuel, the main control unit monitors a huge number of input sensors installed in the system.

The primary functions of the system are to improve fuel efficiency, engine performance, and reduce automotive emissions. At present, the new trend in fuel injection has shifted to multi-point fuel injection system.
