Abstract
In a multi-carburetor engine system, a microswitch is provided for detecting when each of the carburetors begins the transition from the idle mode to the high speed mode in response to actuation of the vehicle's acceleration. The transition is marked by the microswitch closing which in turn causes a lamp to be lit. If each lamp associated with each carburetor does not light at substantially the same time, the carburetors are not synchronized and adjustments are required. A lockout circuit is provided for setting the period of time in which all lamps must light arbitrarily low.
Claims9
An apparatus for indicating when each of a plurality of carburetors are synchronized with each other, each of said carburetors being equipped with a throttle valve which is opened to terminate its associated carburetor's idle mode of operation and initiate its high speed mode of operation, each of said throttle valves being coupled to a throttle valve control mechanism which is responsive to an accelerator control for opening and closing each of said throttle valves, said apparatus comprising:
- a plurality of switch means each one mounted proximate one of said plurality of carburetors and responsive to movement of said control mechanism, each of said switch means assuming a first condition when said throttle valve is in its idle position and assuming a second condition when said throttle valve opens beyond its idle position;
- and
- circuit means coupled to each of said switch means for giving a visual indication when each of said switch means assumes said second condition.
