CONSTITUTION:A synchronous injection calculating and executing means calculates the quantity of synchronous fuel injection from predetermined parameters representing operational conditions of an internal combustion engine in synchonism with a prescribed timing of each cylinder and injects the quantity of fuel to corresponding cylinders by way of synchronous injection. On the other hand, a means for setting an asynchronous injection practicable timing region sets an asynchronous injection practicable timing region for each cylinder, while a means for calculating the quantity and timing of asynchronous injection calculates the quantity and timing of asynchronous injection from other parameters represnting operational conditions of the engine. Further, an asynchronous injection executing means effects asynchronous injection only to the cylinders standing in the asynchronous injection practicable timig region in which an asynchronous injection practicable timing is set. With each an arrangement, it is enabled to lower the specific fuel consumption of an internal combustion engine and to reduce the exhaust emission of the same.

IPC: B65G43/02
Filed: 1992-02-06
Abstract: PURPOSE:To provide a means to detect and control the meandering of a belt conveyor. CONSTITUTION:A taper shape rotary roller 10 is arranged in a position coming into contact with the edge of a belt, and a belt meandering quantity is detected by measuring the number of revolutions of the roller.
