Abstract:
An outboard motor position responsive system is disclosed that warns and/or prevents a powerboat operator from engaging the ignition system of an outboard motor when the outboard motor is tilted up beyond a maximum safe tilt position. The system comprises an outboard motor position sensor that is in communication with an ignition switch, wherein the sensor activates an alarm and/or an ignition disabling switch when an operator attempts to engage the ignition system when the outboard motor is tilted up beyond the maximum safe tilt position. An interval-on relay is also provided that limits the amount of time that the alarm and/or the ignition disabling switch are activated. The interval-on relay further prevents against wave-induced alarms with certain types of outboard motor position sensors in accordance with the present invention. A device is also provided that is easily retrofittable with the existing ignition system of a powerboat.
Abstract:
An electronically controlled engine management system for an outboard motor, which accurately checks the neutral switch for false operation. The accurate neutral switch detection permits an enjoyable boating environment as well as eliminating unnecessary false neutral switch fault alarms.
Abstract:
A method of controlling a vehicle engine involves determining a predetermined start operation, which is usually performed by a driver when the driver starts a parked vehicle, and that is not exclusively performed for starting the vehicle engine, verifying a code with a portable device after determining the predetermined start operation, and starting an engine automatically after successfully verifying the code. An engine control device has a start determining means for determining a predetermined start operation, which is usually performed by a driver when the driver starts a parked vehicle, and that is not exclusively performed for starting a vehicle engine, a verifying means for verifying a code with a portable device after determining the predetermined start operation, and a starting means for controlling an automatic engine start after successfully verifying the code.
Abstract:
A trolling motor position responsive system is disclosed that warns and/or prevents a powerboat operator from engaging an outboard motor while the trolling motor remains deployed in the water. The system comprises a trolling motor position sensor that is in communication with an ignition switch, wherein the sensor activates an alarm and/or a ignition disabling switch when an operator attempts to engage the outboard motor when the trolling motor remains deployed in the water. An interval-on relay is also provided that limits the amount of time that the alarm and/or the ignition disabling switch are activated. The interval-on relay further prevents against wave-induced alarms with certain types of trolling motor position sensors in accordance with the present invention. A device is also provided that is easily retrofittable with the existing ignition system of a powerboat.
Abstract:
A system to prevent injuries due to marine propellers striking swimmers and other persons in the water next to a boat utilizing a switch. The switch is normally in a closed position and is only opened when a movable element such as a ladder, gate, and the like on the boat travels to an unlatched position. Such movement interrupts the ignition circuit of the boat motor. An override device is also employed to allow normal operation of the marine engine and requires both mechanical and electrical interconnection or matting of connector elements.
Abstract:
A spark ignition safety circuit and starting circuit having grounding of the primary winding through safety switches and preferably also through the ignition switch. The primary winding of the ignition circuit is grounded through closed safety switches which are in series with the ignition switch.
Abstract:
A safety system associated with an engine of a marine vessel wherein the safety system includes a blower, a control unit, and a plurality of sensors. An intake pressure detection device is coupled to the intake manifold of the engine for the detection of pressure at the intake manifold. A sensor is coupled to the engine to monitor oil pressure and, along with the intake pressure detection device, transmits a signal to the control unit, with the signals each having a characteristic corresponding to the respective engine pressure. Detection of an engine pressure associated with engine idling or low cruise operation causes the control unit to activate the blower. The safety system includes interactive heat sensors and vapor sensors to monitor the atmosphere in an engine compartment. Detection of a volatile environment activates the blower and triggers both an audio and a visual warning.
Abstract:
An ignition delay vapor expulsion module is provided for accessory use with a boat. When activated, the module energizes an accessory ventilating fan for a predetermined time period. After this time period the fan automatically stops and the ignition is enabled so that the operator can start the engine. By preventing the operator from activating the ignition either before or during the ventilation process, explosive fumes may be safely and completely ventilated. An electronic timer and latching relays are used to implement the timing/switching functions.
Abstract:
The invention provides a system applicable to various internal combustion engines, such as for automobiles, motorcycles, snowmobiles and outboards, to permit an authorized person, such as a police officer, to prevent their improper or illegal operation. The engine includes a detector detecting the speed of operation of the motor which is compared with a preset value. Upon an unusually high motor speed being reached a receiver is enabled for a preset period of time. During this preset period the engine can be disabled by a transmission from a transmitter operated by the police officer, preferably using a designated exclusive channel. The disabling slows the engine to an idle speed without stopping it, so that the power assist mechanisms of the vehicle remain operative to maintain normal braking and steering function.
Abstract:
A starter control circuit is disclosed having particular utility in boats with inboard or inboard/outboard engines. The starter control circuit is coupled to the ignition switch and actuates a ventilation circuit prior to actuation of the starting circuit so that the engine compartment of the boat can be ventilated of any combustible fumes which may have accumulated therein prior to engine ignition.
