Abstract

The engine control apparatus includes: the stop switch body 6; the stop switch knob 3; the lock plate 5 insertable to the stop switch knob 3; the transponder 9 that is provided at the lock plate 5 side and that can transmit an ID code; and the control section 11 for receiving the ID code transmitted from the transponder 9 to control the engine operation. The engine control apparatus includes such that, when the lock plate 5 is disengaged from the stop switch knob 3, the stop switch body 6 is activated to cause the engine to stop or to be in an idling state. In the engine control apparatus, the control section 11 changes the engine performance based on the ID code from the transponder 9.

Claims

1. An engine control apparatus comprising:

a stop switch body for allowing an engine to stop or to be in an idling state;

a stop switch knob that abuts with the stop switch body to activate the stop switch body to allow the engine to stop or to be in an idling state;

a lock plate including an attachment member for attaching the lock plate to an operator, wherein the lock plate is detachably engaged with the stop switch knob so that, when the operator pulls the lock plate via the attachment member, the lock plate disengages from the stop switch knob;

a transponder that transmits a predetermined ID code and is detachably attached to the lock plate or other structures on the engine control apparatus; and

a control section that receives the ID code transmitted from the transponder and that controls the engine operation based on the ID code, wherein

when the lock plate is disengaged from the stop switch knob, the stop switch body is activated to stop the engine or put the engine in an idling state.

2. The engine control apparatus according to claim 1, wherein the start switch knob is provided to a switch case at an inclination angle from vertical.

3. The engine control apparatus according to claim 1, wherein said transponder is a first transponder and said ID code is a first ID code based upon which the control section controls the engine performance in a first manner when the first transponder is attached to the lock plate and the lock plate is engaged with the stop switch knob;

wherein the control apparatus further comprises a second transponder having a second ID code based upon which the control section controls the engine performance in a second manner different from the first manner when the second transponder is attached to the lock plate and the lock plate is engaged with the stop switch knob; and

wherein the control apparatus is configured to be operable with either the first transponder or the second transponder selectively attached so as to control the engine performance in accordance with the selectively attached first or second transponder.

4. The engine control apparatus according to claim 3, wherein the control section controls the engine based on the first ID code so that the engine runs at a relatively lower speed compared to the engine speed when the control section controls the engine based on the second ID code.

5. The engine control apparatus according to claim 3, wherein the control section controls the engine based on the first ID code so that the engine responds to actuation of an accelerator in a relatively longer time compared to the engine response time to actuation of the accelerator when the control section controls the engine based on the second ID code.

6. The engine control apparatus according to claim 1, wherein when the control section receives an unrecognized ID code, the control section controls the engine to be only in an idling state.

7. The engine control apparatus according to claim 1, wherein the transponder is detachably attached to the lock plate.

8. The engine control apparatus according to claim 1, wherein the control section controls the engine performance based on the ID code transmitted from the transponder.
