There are various measures for the improvement of fuel efficiency.

With today's automobile technology, you can find fuel efficiency improvement in every part of the total mechanism.

Generally speaking, these techniques are divided into 4 parts such as engine improvement including low friction of the engine, transmission improvement, weight improvement, aero dynamics improvement and so on.

At Techno Gallery, an example of each technology is exhibited according to above classification. Most of these examples are current cutting edge technology which is reflected in Japanese 1996 models cars.

Engine improvement
It is very important to burn fuel completely for the improvement of fuel efficiency. On the other hand, it is also essential to minimize the friction within the engine. As for other mechanisms, fuel injection method, air intake method, light weight efforts and prominent electronically controlled engines are also significant technology for engine improvement.

Transmission improvement
Converting the power generated by the engine into adequate revolving speed, we can improve the fuel efficiency as well. Transmission (gear ratio) and torque converters are also important improvement factors, in addition to minimizing the power loss during conversion. Many of such methods are exhibited in this corner.

Light weight technology
Thinking of automobile acceleration, if the weight is reduced to half, the necessary power can be reduced to half accordingly. It is also reported that if car weight is reduced by 10%, the fuel efficiency shows 8 to 10% better performance. However, too much light weight improvement might cause stability and intensity problems. Therefore an adequate method which incorporates various analyzing technologies is necessary.

Minimizing air friction
Automobiles run against air streams from the forward direction. This friction will increase with the square of the speed increase, and it also changes according to the body styling. Current passenger cars have well considered this point.
