Embodiment Construction

[0020] Realize the combustion work time of optimal optimization diesel engine, be to rely on the new type piston combustion chamber (12) of the work new system of direct injection diesel engine and the new type fuel injector to finish. First, after the quantitative change of the volume of the combustion chamber, the diesel engine is burned at 2 degrees before the top dead center to 2 degrees after the top dead center, that is, the volume of the new piston combustion chamber (12) of the new work system of the direct injection diesel engine makes the diesel engine burn at the same time after the quantitative change of the volume of the combustion chamber. The pressure at 3 degrees before top dead center is not enough, resulting in the high temperature caused by high pressure cannot make the atomized oil burn, and it will burn at 2 degrees; at the same time, the new fuel injector completes the work at 2 degrees before top dead center to evenly distribute the fuel required for work....

Abstract

The invention provides a new acting system of a direct-injection diesel engine. The new acting system is composed of a novel piston and a novel oil atomizer. A head combustion chamber (12) of the novel piston is provided with a horn mouth (14), two air ring grooves (6 and 7), chroming ring grooves (8) and oil ring grooves (9), and a piston pin base (10) is internally arranged and connected with a connecting rod through a piston pin. The novel oil atomizer comprises a pair of precise coupling pieces (1 and 2), an oil atomizing hole (5) is formed in one end of the novel oil atomizer, and an oil inlet (4) and a positioning pin base (3) are arranged at the other end of the novel oil atomizer. The positioning pin base (3) corresponds to a positioning pin base at the waist part of an oil atomizer assembly, and after a positioning pin is arranged, the oil atomizer assembly can be achieved through fastened connection via nuts. Accordingly, combustion acting is carried out under the conditions of the optimal time range, the optimal space and the even fuel oil distribution. According to the technical improvement, the resistance generated by combustion of the diesel engine is thoroughly eliminated, the relatively complete combustion acting is achieved, and the post-toe combustion is eliminated. The comprehensive performance of the diesel engine is improved, oil consumption and emission are reduced, and flameout and reverse starting caused by combustion are avoided.

Description

technical field [0001] The invention relates to a new work system of a direct-injection diesel engine, which belongs to the field of internal combustion engines. Background technique [0002] At present, the combustion work of the diesel engine has been innovated and transformed by a large number of technical personnel, but the combustion angle is 35 to 40 degrees. In the case of 2200 rpm, the combustion time is 0.00275 seconds. The whole process includes the process of doing positive work; Including the process of diesel engine combustion as reverse work, scientifically speaking, oil supply and combustion work at 20 degrees to 0 degrees before top dead center will always produce resistance to hinder the piston from running to top dead center, automatic flameout caused by combustion will also occur, and combustion will also occur The resistance work is greater than the work done by the flywheel inertia of the diesel engine, causing reverse ignition; at the same time, it also...
