Inserting ring carrier to the wearing piston of high-power medium speed diesel engine is a useful repaired way.

大功率中速柴油机磨损的活塞镶装镶圈是一种有效的修复方法。

In order to avoid stress concentration which result in the break of the ring carrier, this paper made a Finite Element analysis of the ring carrier inserted in the piston of a high-power medium speed diesel engine using ANSYS.

为消除某中速柴油机活塞镶圈在热负荷状态下产生应力集中而发生断裂现象，采用ANSYS有限元分析软件对该合金钢活塞镶圈进行有限元分析。

The experimental results show that most of the diesel particulates are wad-shaped and chain-shaped and composed mainly of organic compounds or carbon particles covered with organic compounds. The peak value of the diesel particle size distribution is about 40 nm. In the exhaust gas, the PM concentration was 32. 6mg/m~3～143.6mg/m~3, NO_x 208 × 10~(-6)～ 568×10~(-6), SO_2 18 × 10~(-6) and HC about 16 × 10~(-6)..

实验结果表明，颗粒物大多呈絮状及链状形态，其构成主要为有机物或为有机物所覆盖的碳微粒，粒径分布峰值约为40nm；柴油机废气中颗粒物浓度为32.6mg／m~3～143.6mg／m~3，NO_x浓度为208×10~(-6)～568×10~(-6)，SO_2和HC化合物浓度分别为18×10~(-6)和16×10~(-6)。

A more precise QDM is developed for simulating the working process of swirl chamber diesel engine, based on a series of tests.
