Integral Relationship to Facilitate the Analysis of Supercritical Discharge Process
// Dvigatelestroyeniye. ? 2003. ? ? 1. ? P. 16?19.
Keywords: diesel engines.

New formula for cylinder pressure calculation is derived based on received quasi-stationary approach to supercritical discharge process. As compared with known relationships, the proposed formula is structurally simple and apparently logical in terms of thermodynamics basis. Approximate relationships are offered to simplify calculations.

Shaping Boundaries between Microstructures in Crankshaft Blank
// Dvigatelestroyeniye. ? 2003. ? ? 1. ? P. 22?23.
Keywords: diesel engines.

A thermal treatment technique is discussed that results in lower deformation of heated crankshaft blank. The author offers a method of shaping boundaries between microstructures, whereby form and location of these boundaries may be preset and predicted. Needed patterns of inter-struc- ture boundaries dislocation and intersection may be obtained. The method enables to improve quality of hardened crankshaft journals.

Operation of Diesel Engine Type 2CH10,5/12 on methanol/diesel fuel mix
// Dvigatelestroyeniye. ? 2003. ? ? 1. ? P. 36?37.
Keywords: diesel engines.

The article discusses test results obtained on engine firing methanol/diesel fuel mix. The idea is to partly substitute diesel fuel with methanol, the methanol proportion being as high as possible. Ways are outlined of how to achieve the above goal. Stand test data are presented along with the results of heat release dynamics calculations. The authors' conclusion is that use of methanol/diesel fuel mix is feasible and recommendable.
