Simulation of Stress Patterns in Connecting Rod Piston End of High-Powered Diesel Engine
// Dvigatelestroeniye. — 2007. — Ή 3. — P. 14–15.
Keywords: connecting rod, tensile load.

Stresses developing in connecting rod piston end of high-powered diesel engine have been simulated with photoelasticity method on a flat model. This simulation yielded isochore patterns (on qualitative level) and stress distribution diagram (on qualitative level) in a connecting rod under tensile load.

Modular Stirling Engine
// Dvigatelestroeniye. — 2007. — Ή 3. — P. 16–19.
Keywords: Stirling engine.

This work offers an alternative kinematical outlay of the engine that entails no over-strict manufacturing precision requirements. The mechanism in question is a module consisting of two b-engines connected to one crank. Such modular approach allows to yield a Stirling engine that would develop required power at moderate levels of actuating medium pressure and temperature.

Calculation of Temperature in the Area of Contact Between Cylinder Liner and the Upper Compression Ring of a Diesel Engine
// Dvigatelestroeniye. — 2007. — Ή 3. — P. 20–25.
Keywords: cylinder liner, compression ring.

The authors researched physical basics of friction in the area of contact between cylinder liner and the upper compression ring, and offered a mathematical model of the above process. Based on this model, they calculated temperature in friction pair ˜cylinder liner˜upper˜ compression ring, which enables definition of critical operating conditions for this pair.

Analytical Correction of Actual TDC Position as Defined from Engine Indicator Diagram
// Dvigatelestroeniye. — 2007. — Ή 3. — P. 34–38.
Keywords: actual TDC.

Considered are sources of discrepancy between the positions of actual TDC and peak cylinder pressure on indicator diagram time axis. Based thereupon, a method of correction of actual TDC position is offered, taking account of actuating medium leakages and heat exchange in the cylinder. An implementation algorithm of the method in question is offered.
