The 6-stroke conceptual design can be transplanted to existing engines without redesign. It removes the cylinder head, mushroom valve train and camshaft from the existing engine. The camshaft drive belt is retained and used to drive the ultra-short-stroke upper-mounted crankshaft of the tomb movement (the rotation speed of this crankshaft is 1/2 of the engine speed)
Like a two-stroke engine, The upper piston moves up and down in the preparation sleeve to open and close the inlet and exhaust ports. The mixed gas enters the cylinder through the intake leaf spring valve to prevent exhaust gas from being discharged through the intake port.
At the other end of the upper-mounted crankshaft is a rotary (disc) valve, whose function is to adjust the exhaust airflow and cut off the exhaust gas at the appropriate time to prevent the exhaust gas from returning to the cylinder. Since the rotary valve carries light loads, lubrication and sealing problems are reduced.
For the sealing of the rotating cylinder wall, the lower piston adopts a flat-top three-ring design, and the conical upper piston is equipped with two rings - one gas ring and one oil ring. Since the upper piston is designed in a conical shape, it can better guide the air flow during the two strokes.
There are two spark plugs in the combustion chamber. It is not only suitable for using pure gasoline models, but also can use low-octane unleaded fuel.
Beare's technology has recently been matched with the new Pulse Fuel Injection System and has been tested by the US Maritime Warfare Center and other international authorities. This system is not like a common injector. The turbocharged air is mixed with the atomized fuel in the cylinder (diesel engine and direct injection gasoline engine), or mixed with the fuel before atomization, and in the intake system Set up a pulse booster device to increase efficiency and reduce emissions. This nozzle technology was developed by Ford to control diesel emissions.
