15 engines in 1: Honda patented an interesting engine variable displacement

manufacturers don’t know what to do to increase the efficiency and performance of your engines, above all, without firing costs. There are many ideas which, combined, make us dream of the perfect engine, but still today we turn to ideas archiconocidas that have been evolved with the passage of time. Long ago that we do not know a true revolution in internal combustion engines, however Honda could surprise upon discovering a patent for a motor design with variable displacement, capable of altering its operation to work with up to 15 displacements different.


On paper the idea is very good, however, it will be very difficult to see a street car using this technology

through the co-Autoguide we have known about the patent of Honda registered in the patent office japanese related with a design of impeller capable of altering the volume of each cylinder by varying the length that goes through the piston in its reciprocating motion. On paper, this idea offers endless possibilities in terms of fuel consumption and performance, since an engine as patented by Honda alter its displacement in function of the power demand that we.

The concept of motor variable displacement, not to be confused with the engines variable compression Saab or Peugeot–Citroen, based its operation in the a real capacity to alter the travel of the piston from bdc (Lower Dead Point) to the PMS (Upper Dead Point), thus modifying the volume aspirate performed by the piston in its admission stage. If that tour can be modified, the engine could work under different displacements, up to 15 according to the patent. Limiting ourselves to the early sketches discovered of Honda, this technology could be applied to engines of 3, 4 and 6 cylinders, which would be the bulk of the engines available in the range Honda.


The future is Turbo, so What do you think knowing the 5 major technologies Turbo that we will see under our hood?

we must Not forget that the concept of motor of variable displacement is not new to say. There are several patents that pose this concept, though never no one has dared to exploit the possibilities of these mechanics, beyond laboratory or experimental tests. The patent of Honda is not or much less a first step towards the production, is just that, an idea registered as so many others. In the process of electrification, it seems very difficult that a manufacturer decides to take the risk to reinvent the internal combustion engine. The idea is good, but its complexity and cost of development and deployment are critical factors.
