The need for car manufacturers to go green resulted to the creation of innovations such as the electric or hybrid vehicles. These technologies are totally different from the systems in today's cars. With Fiat, years of studies finally bloomed into useful and practical innovations as its own pursuit of green cars takes a different route. Instead of inventing new technologies, their relentless research department has come up with ways to improve existing parts to create environmentally friendly cars.
One of the biggest contributors to the problems of pollution from cars is the hazardous and inefficient diesel engine. To combat this, Fiat created the MultiJet (the descendant of another Fiat innovation: Common Rail) to improve on the parts of the engines. With improvements like added injectors, the system can improve the mix of the fuel ratio and combustion sequence. The result is lower CO2 levels and an improvement in fuel economy. This transforms it from a slow and noisy machine into a smooth and powerful one.
Their eco-friendly innovations are not limited to diesel engines. Gasoline engines have their share of improvement through the introduction of the MultiAir system featured in the Fiat Punto Evo and the Fiat 500 Twin Air. It works through a computer-controlled electro hydraulic system that manages the air flow coming into the engine. Air bypasses the throttle valve as it goes straight to the intake valve. The system boasts a 10% improvement in horsepower, a 15% torque increase, and a 10% decrease in CO2 emissions. The great thing about MultiAir is that is applicable to use for any gasoline powered engine.
Dual Dry Clutch Transmission
Other than the engine, Fiat also innovates to improve the existing automatic transmission system. Its innovation is a big improvement to today's systems. With the Dual Dry Clutch Transmission (DDCT), Automatic transmission cars will have the power and fuel efficiency as that of a car with manual transmission. Numbers show that using two clutches gives it a 4% decrease in gas consumption compared to a regular manual transmission. Even better is the 10% cut in consumption of DDCT to cars with an automatic transmission.
