TH7367B - Combustion controller for 2-stroke, spark-ignition engines. - Google Patents

Abstract

Combustion regulator for a 2-stroke engine, which can Always ignite manually at the optimal timing. Was prepared to happen, the combustion controller consists of The exhaust control valve 15 is arranged in close proximity to the exhaust channel 7 of the 2-stroke engine 1 and can be completely closed to the exhaust port and control components. Drives 47, 38, 39, 40 and 37 to drive the Exhaust Control Valve 15 according to the control scheme, which provides an Oe exhaust opening ratio based at least on engine speed. And the Oth throttle valve opening ratio to regulate the pressure in the cylinder during the Piston uptakes 8 control valve 15 are molded with shell-like components, some of which include Exhaust control 35 located along the curvature of the cylinder in the exhaust channel 7 and with a wide Over the total width of the exhaust port and swing arm section 34 for a minimum connection Side of the exhaust control and rotating shaft 33 that are perpendicular to the axis of the cylinder and are supplied To be placed in the receptacle that was created in the cylinder block This receptacle is connected to the exhaust channel. Which extends from the exhaust channel 7 just in the work part of the exhaust control

Claims (5)

1. Combustion controller for 2-stroke engines with ignition type. A spark that causes the combustion of a new mixture in the combustion chamber to occur by self-ignition. Own, at least for operation at low loads. Including The exhaust control valve is positioned in the exhaust channel and is capable of To completely close the exhaust channel and Up the drive control device that drives the exhaust control valve to To achieve a predetermined exhaust opening ratio for cylinder pressure control. It is pumped during the piston stroke to regulate the timing of the self-ignition. 2.Combustion controller for 2-stroke, dash-ignition type engines. A fire body that causes the combustion of a new part in the combustion chamber to occur by self-ignition. At least for operation with low loads. Including The exhaust control valve, which is positioned in the exhaust channel, is capable of To completely close the exhaust channel and the drive control piece that drives the exhaust control valve to allow Yes, according to the predetermined exhaust opening ratio, at least dependent on the rev. Engine and throttle valve opening ratio To control the pressure in the cylinder During the rise of the piston to control the timing of the self-ignition 3. Combustion controller for 2-stroke engines with ignition type. The sparks followed in claim 2, which ascertained such a propulsion device that drives the control valve. Control the said exhaust according to the control plan Which determines the opening ratio of the exhaust depending on The engine speed and throttle valve opening ratio thereof 4. Ignition regulator for 2-stroke engines with dash-ignition type. The fire body according to claim 1, where the exhaust channel extends from the exhaust hole to the The surface along the inner ring of the cylinder holes The exhaust control valve consists of a rotating shaft that is at a right angle to the line. The cylinder rod and valve body are supported on the rotating shaft to vary the section height. The top edge of the exhaust channel. The valve body is molded into shell-like components, some of which consist of Controls the exhaust which is located along the curvature of the cylinder at the said exhaust channel and is wider. The total width of the aforementioned exhaust port and the least connected swing arm to the side of the The exhaust control and the rotating shaft and the receptacle for the complete containment of the valve body are built into the cylinder block. Which is provided to have a channel through the exhaust. By the said niche is connected with Such exhaust channels, but only in the said exhaust control function, and The swing arm is placed in the recess. 5.Combustion controller for 2-stroke, dash-ignition type engines. In accordance with claim 2 or 3, the exhaust control valve is driven to close the channel. Throughout the exhaust, it is almost completely low when the throttle valve opening ratio is very low, with the exception of zero and low to medium engine speed.
