Effect of Applying Interception Valve to Suction Passage.

Callenge

It proposes 4cycle engine structure to enable the improvement of a big engine characteristic by the simple structure.

Solution

The interception valve is installed around the suction valve(No.15) in the suction passage,and it opens and shuts according to the suction timing.


Theory

The suction efficiency is improved by temporarily catching the pressure generated around the suction valve in the suction passage Immediately after suction,and using the pressure for the following suction.

Control

Figure shows an ideal example of the valve of the opration timing.
Pulse Chart

Figure shows the pressure in part A,after close suction valve.
Effect

Figure shows the engine output characteristic of the interception valve application exietence
Note

This technology has been registered to japan patent office.
