Abstract

First time the corresponding author has studied these problems of motors in V, in the framework of some contracts made with the research collective of UPB and "Autobuzul" plant, in years 1980-1986. In the first phase, have been studied the vibrations and noises of an engine in V, their transmissibility from the engine to the chassis and the cab driver and the possibility of reducing vibration (of the engine or the submitted) by their insulation. Reducing the vibration transmitted, has taken place in various ways, but their level at the driver's seat and the passengers was still too large, much more than the allowed limits international. The vibrations were still more than the allowed limits, while in a similar engine Otto or diesel in a straight line, they were in line with the normal limits, until at last it was decided to change the type of the engine. The idea of the paper's authors was: "It can be synthesized one motor in V only by changing the alpha angle value (the constructive angle of a V engine)". By this method it is possible to change the kinematics of this motor and in the same time its dynamic work. Generally the constructive angle of an engine in V was calculated in function of the number of cylinders and by the engineering condition to achieve an ignition distributed uniformly to all cylinders. This paper try to solve the principal problem of any motor in V (noise and vibration) having in view that one motor in V is more dynamic, more powerful and has a higher yield than any other heat engine. The solution was found and it is very simple to be implemented. It needs only an angle value change. It's about the constructive angle, alpha. Calculations to demonstrate this fact and all the theory are very difficult and heavy. But the final result is very simple.
