Toyota has stated that until 2015 will the new petrol engines in 14 variations. They will all be on 10-30% more economical than their predecessors. Savings will be achieved including through the use of the Atkinson Cycle, exhaust manifolds, compression ratio, etc.
Toyota has published a short but important press release regarding the new engines. The Japanese promise that 2015 will develop new petrol engines in 14 variations. However, in this case, the important thing is not the quantity but the quality of upcoming products. The Japanese claim that their new developments make it possible to achieve the highest thermal efficiency of 37-38%.
While information are too little. We only know about two small motors. One (working volume of 1.3 l) has the following distinctive features. First of all, the intake tract of this engine an unusual shape that allows you to generate the "right" of vertical turbulence in the cylinder. It has EGR. And the most important is the use of the Atkinson cycle. This motor can turn the wheels without the assistance of the traction motor, thus Toyota has solved the problem of the failure of torque at low revs.
About the second motor. The press release contains information only about the fact that he liter. Developed staff of Toyota with a Daihatsu. The motor a high compression ratio, which suggests that it also used the same techniques as in the above-described motor. An important feature of this engine is the presence of a "start-stop" which suppresses the engine at idle.
Toyota said the new motors can be seen already on the current models (after updating them). Well we expect the release of these new motors. Maybe one of them will we see on the popular Camry sedan, an upgraded version which will be presented in new York during the upcoming motor show.
