Title: Carburetor in spark ignition engine
Inventor: FUKUSHIMA TSUGIO
IPC: F02M31/00
Filed: 1984-02-18
Abstract: PURPOSE:To make an engine start so easily with kerosene alone, by lowering one step down the point midway in a pipe line connecting a second float chamber to be interconnected manually in time of starting to the downstream side of a throttle valve, while setting up a heater body for fuel gas in the said point, and heating the heater body in time of starting the engine. CONSTITUTION:When a manual on-off valve 15' installed in the bottom of a first float chamber 9 of a kerosene engine is opened in time of starting, fuel flows into a second float chamber 10' whereby each liquid level of both first and second float chambers 9 and 10 becomes exactly alike due to action of a valve 18 of a float 13. If cranking takes place, in a state that a throttle valve 5 is closed, kerosene is sucked up by dint of suction pressure via a pipe 22 and a throttle 21, and it is heated and gasified by a heater body 25 installed in a position being down one step lower as far as a portion for A than the second float chamber level at the point midway of the pipe 22 so that it is fed to an engine. In proportion to a level drop in the second float chamber 10', the height of said A varies to some extent, and since a siphon effect is reduced in consequence, excess fuel for starting is automatically decreased in quantity.

Filed: 1978-03-15
Abstract: PURPOSE: To prevent pointer swinging owing to the fluctuations of fuel liquid level by driving bimetals with the mean DC voltage of a unit resistance whose resitance value changes in response to the displacement of a float.  
     CONSTITUTION: The resistance value Rab of a unit resistance 103 whose resistance value changes in response to the displacement of a float 101 is constantly fluctuating owing to the fluctuations of fuel liquid level but the voltage Vin at the point 104 of connection between the unit resistance and a resistance 204 is smoothed by a smoothing circuit 220 having delay action and the voltage Vout which has sufficiently lowered the impedance of this smoothed voltage is obtainable on the output side of an operational amplifier 205. Hence, it turns out that a resistance heating element 203 is driven by the mean DC voltage of a sensor part 100 owing to the current suction action of the operational amplifier 205, thus the voltage fluctuations are suppressed as far as possible and there is no more pointer swinging of an indicating gauge.
