Mazda Motors working on gas engine more efficient than a hybrid

Recently, Mazda Motors announced that the business is testing a motor that will get 70 miles per gallon. Ford Motors is working on a comparable project with their 45 miles per gallon Focus. The motor won’t be a hybrid in the least, however a high efficiency internal combustion motor. The technology is complex, but the principles at work are quite basic.

Mazda engine outdoes hybrids

CNN reports that many have been talking about the new Mazda engine. The prototype is intended to achieve 70 miles per gallon, or close to it. Having a low fuel consumption than that is something everyone wants. It needs to be decently priced though. There could be two technologies used by the motor. Variable valve timing and direct fuel injection are these. Direct injection is when fuel is injected directly into the piston chamber instead of through a fuel injector on top of the block, for more precise ignition. Normally, there would be mechanically set and unvarying vale operation while variable valve timing makes it so there is a more efficient rhythm within the automated computer. It is new technology that is getting used. Of course, it is a really basic idea still.

Simple ideas involved

The 45 mpg Focus is using a basic science. This is how the Mazda motor is made. Involved are two important principles. Included are mechanical efficiency and mechanical advantage. Mechanical efficiency is a ratio of energy expended to work performed. Mechanical advantage is how much force a machine can produce from a unit of energy. How it relates to engines is the more power that can be extracted from a unit of fuel, or the greater the mechanical advantage, the greater the fuel efficiency could be.

Actually doing it

Put simply, injecting gasoline in the right place at the right time will produce more force, and thus be more efficient, than traditional fuel injection. Turbocharged smaller engines are an answer also. Efficiency is increased there as well. Hybrid technology is still just starting out although it is a great technology. The traditional combustion engine can be used for a long time still. It can be fun to view how technology can advance with it.
