Abstract

A valve D prevents-the return of air drawn into the air filter housing G to the air intake F. Gases from the engine sump are fed to the housing G from the dip stick housing H. <IMAGE>

Description

Title: INPUT DEVICE This invention relates to the Internal Combustion Engine.
Background: The internal combustion engine remains the main type used to power vehicles. The efficiency, economy and performance are continuing to dominate the design.
Reason for Invention: This invention may be used to improve efficiency, economy and performance.
Description: The invention harnesses the air that is ventilated from the sump. The air pulsates at a rate that is determined by the engines natural rotation and is generally in phase or sympathy with the air/fuel or air input cycle. This air is ventilated from the sump into the same cavity as the air that is drawn into the input manifold for burning the fuel.
The valve is placed in the air inlet to this cavity. The valve stops air that has entered the system escaping.
Figure 1 (Sheet 1/2) shows air "C" drawn into the engines sump via vent "A" though the open SECONDARY INLET VALVE "D", by piston motion within the sump cavity.
Figure 2 shows air expelled from the sump (vent "A") by piston movement, driven into the inlet manifold "B" on the inlet stroke of a piston, because of the addition of the SECONDARY INLET VALVE "D".
This combination of events create extra pressure within the input system, enhancing the flow of air/air fuel into the engine.
In the standard configuration without the SECONDARY INLET VALVE a path would shave been present for much of the air from the sump to escape through the unrestricted air inlet. As with the invention the input to the system is closed off over the required period by the SECONDARY INPUT VALVE, the air is forced into the cylinder by the air expelled from the Sump.
Any natural resonances of all/any/or combinations of cavities may be used to enhance the action of the invention.
The SECONDARY INLET VALVE may be passive or active in operation. A self operating passive type has been found to be satisfactory.
The invention has applications for all types of internal combustion engine Figure 3 (Sheet 2/2) shows a typical example of a passive SECONDARY INLET VALVE "D" fitted to a standard air input system of a Peugeot 205 Diesel. The valve in this instance is hinged above the circular input port to the air filter. The parts are as described in the previous text, with the addition of "F" which is the air inlet Tube, "G" which is the air filter housing, "H" which is the dip stick housing which gives the connection to the engine.

Claims (10)

1) The input device comprising a valve preventing air having entered the input ducting system of an internal combustion engine from escaping.
2) A device as claimed in claim 1) being placed at the air inlet point of the ducting.
3) A device as claimed in both previous claims that is free to move under the influence of the incoming air/air pressures.
4) A device as claimed in all previous claims to be clear of the inlet hole when air is coming into the ducting, and cover the inlet hole when air tries to escape.
5) A device as claimed in all previous claims that is light enough to respond to rapid changes of direction of air movement.
6) A device as claimed in all previous claims that has a hinge\hinges that will withstand continuous flexing.
7) A device as claimed in all previous claims that may be used in conjunction with an acoustic resonator within the ducting to enhance the pressure within the same.
8) A device as claimed in claims 1 through 6 that may be used in conjunction with variations in sump pressures.
9)) A device as claimed in claims 1 through 7 that may be used independently from sump pressures.
10) A device as claimed in claims 1 through 7 that may be used in conjunction with a moving coil pump (loud speaker).
