Abstract

The invention discloses a weight-reduction steel piston of a diesel engine. The weight-reduction steel piston of the diesel engine comprises a piston body, a combustion chamber, a piston oil channel and piston surface windows. A steel structure is adopted by the piston body, and the piston body comprises a piston top, a piston head portion and a piston skirt from top to bottom. The combustion chamber is formed in the upper portion of the piston body; the contraction port of the combustion chamber is of an omega type; and an inclination angle ranging from 10 degrees to 15 degrees is arranged atthe position of the throat of the combustion chamber. The piston oil channel is arranged at the portion which is 5-7 mm below the top of the piston body. The piston side windows are arranged on the outer side of the piston body. According to the weight-reduction steel piston of the diesel engine, high detonation pressure and reliability are satisfied; and meanwhile, weight of the steel piston perse can be reduced, and compression height can be lowered.

Description

technical field [0001] The invention relates to the field of diesel engines, in particular to a weight-reducing steel piston of a diesel engine. Background technique [0002] With the implementation of the National VI emission regulations, in order to ensure the low emission performance of the gas engine engine, as the engine power increases, the explosion pressure in the cylinder increases, and the traditional aluminum piston can no longer meet the demand for high explosion pressure resistance. [0003] The high strength of the steel piston solves the above problems well. The density of the steel piston is higher than that of the aluminum piston, so that the weight of the steel piston with the same bore is larger than that of the aluminum piston. The invention provides a solution for reducing the weight of the steel piston. [0004] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present inventi...
