On Effect of Controlling Maximum Quantity of Fuel Injected in Small Type's Diesel Engines

Abstract

The writer examined on the effect of controlling the maximum quantity of the fuel injected in the small type's constant speed diesel engines, which is mainly used in agricultural machineries, on the decrease of the fuel consumption in the over load range, the improvement of combustion and the working ability of agricultural machineries, carrying the fluctuating load. The results obtained may be summarized as follows;
(1) By means of controlling properly the maximum quantity of the fuel injected, combustion is improved and engines are always changed into the constant torque type and moreover the engine power can be adjusted at will.
(2) The fluctuating load performance of engines, carrying the severe fluctuating load in the agricultural work, coincide with the engine performance of the bench test.
(3) By means of controlling properly the maximum quantity of the fuel injected, the work quantity per unit fuel consumption increase 10-20% in the overload range.
