Automobile manufacturers around the globe are eyeing on new ways to save fuel and increase the economy of their cars. They are pushed to do this because of the increase in fuel price and depletion of fossil fuels. So following are some technologies that are employed in new car models in the event of saving fuel. If you are planning to buy a new car do check for these money saving technologies.
Direct Injection: Fuel injection techniques are being adopted instead of carburetors because engines using carburetors require higher maintenance when compared to fuel injection engines. As a part of improvement nowadays we find direct injection engines or sometimes total direct injection engines which have proved to be more efficient. In such engines the air is mixed with gasoline in the inlet manifold and sprayed inside the cylinders. The cylinders are provided with individual injectors which help in the spraying action. These engines are little expensive as the number of parts used is more. However the engine’s efficiency increases as the gasoline sprayed is burnt uniformly inside the cylinder. These injectors help in spraying equal and required amount of fuel for burning.
Turbochargers: Turbochargers were used widely during the First World War. Later this technology was used in racing cars as this would increase the performance of the engine. The exhaust from the engine is used to rotate a turbine which in turn pressurizes inlet air on the other side. Therefore pressurized air is supplied inside the cylinder thereby increasing the performance. For example, six cylinders engine with turbocharger would be enough to supply power equal to an eight cylinders engine therefore saving the fuel. When the driver accelerates, turbocharger comes into play by supplying additional power required. Whereas in steady cruising, the turbocharger becomes idle and power from the six cylinders engine is supplied.
Dual-clutch system: This system is the combination of both automatic and manual transmission. It is used to reduce the time lag in manual transmission and the low fuel economy in the automatic transmission engines. This technology uses computers for controlling the clutches. When the driver shifts the gear, say from second to third, the computer would be ready for the driver, by guessing the probability, whether he would shift to second or the third next and acts accordingly thereby reducing the time lag while shifting the gears.
Cylinder displacement: Cylinder displacement or variable displacement or variable cylinder management is one of the recent advancements in automobile engine for improving fuel economy. This method deactivates some cylinders to give the required power. When this engine is at steady speed the engine deactivates 2 to 4 cylinders whenever full power is not required. Then when accelerated, the deactivated cylinders get activated once again, to deliver full power.
