摘要： An engine output control device is configured to detect an actual engine speed and to determine a modified engine speed based on the actual engine speed that is more in proportion to the speed of the watercraft than the actual engine speed. The modified engine speed can be used to control the output of the engine so as to provide a more natural feeling for the operator of the watercraft. The modified engine speed can also be used as an indication of the speed of the watercraft. As such, the modified engine speed can also be used to determine the extent to which the output of the engine can be raised to provide additional thrust for steering purposes.

摘要： A lubrication system for an engine having a fuel system including a floatless carburetor is disclosed. The engine has an intake system through which air is supplied to the engine, the carburetor associated with the intake system and arranged to deliver fuel into air passing through an air flow passage therethrough. The carburetor has a main fuel supply line extending between a fuel supply chamber and a discharge to the air flow passage, a first one-way type valve arranged along the main fuel supply line, a diaphragm dividing the fuel supply chamber from an air chamber, the air chamber coupled to an air source whereby movement of the diaphragm causes fuel to be discharged through the main fuel supply line to the air passage. The lubrication system is arranged to deliver lubricant from a supply through a lubricant supply line communicating with the main fuel supply line between the first one-way type valve and the discharge.

摘要： An elevator overspeed protection apparatus includes a brake apparatus which makes use of eddy currents. The brake apparatus includes a magnetic spring placed on a car in the proximity of a pickup of the elevator overspeed protection apparatus such that, when an arm of the brake apparatus is in a horizontal condition, a displacement of the pickup is prevented with a strong attracting force by the magnetic spring, but when the arm is inclined obliquely, the attracting force of the magnetic spring is prevented from acting upon the pickup. Due to the construction, the brake apparatus operates stably and with certainty and has an increased life.

摘要： A number of embodiments of exhaust silencers for marine propulsion units including an exhaust device having a first expansion chamber, a pair of second expansion chambers and a third expansion chamber all formed within a common housing. The flow of exhaust gases is from the exhaust of the engine into the first expansion chamber, directly from the first expansion chamber into each of the pair of second expansion chambers and directly from the second expansion chambers to the third expansion chamber. In all embodiments the flow from the second expansion chambers to the third expansion chamber is in confronting relationships so as to improve silencing. In one embodiment, the second expansion chambers have different effective volumes so as to provide an extended range of tuning for the silencing.

摘要： A number of embodiments of engine spark control systems wherein the engine speed is reduced in response to the sensing of an abnormal or an external condition and wherein the spark timing is altered when the spark is interrupted to preclude the likelihood of backfiring in the exhaust system or firing back in the induction system. In some embodiments, the sensed condition is an abnormal running condition and in other embodiments the sensed condition is shifting of the transmission. The backfiring and firing back is precluded primarily by advancing the spark from the idle spark advance.
