Lowering emissions of marine auxiliary engines during transients
// Dvigatelestroyeniye. ˜ 2001. ˜ ˜ 2. ˜ P. 8˜10.
Keywords: diesel engines.

Frequent load changes are known as detrimental to engine emission characteristics. This is particularly true for marine auxiliary engines, operating up to 60-70% of their run time under changing load. A special simulation code has been developed and applied. The analysis results have been validated with experiments run on MAN-B & W Holeby engine (6˜˜22,5/30). A nalytical and test results have demonstrated that transient pollutant contents in exhaust gas can be reduced by special pre-setting of engine speed governor and boosting its turbo-blower.

Evaluation of lube oil additives' effect on wearing quality and tribological characteristics of ˜gray cast iron˜ electroplate chrome˜ tribological situations
// Dvigatelestroyeniye. ˜ 2001. ˜ ˜ 2. ˜ P. 23˜25.
Keywords: diesel engines.

Lube oil compositions with various anti-friction and anti-wear additives have been tested. The tests have been targeted at evaluation of how each particular additive effected performance of such tribological situations as "gray cast iron cylinder liner-chromate treated piston ring", characterized by high friction of boundary. 30 tribological situations have been investigated. Resulting empirical curves have been analyzed in terms of structure/energy theory of wear. Functions yielded well fit the general energy-related wear model.

Keywords: diesel engines.

New method is briefly described enabling evaluation of how efficiently heat is used released at particular stages of engine combustion process. The method suggests the ways to enhance engine thermal efficiency. The results are given of comparative thermodynamical analyses of ˜70 engine featuring standard and newly offered heat release characteristics. The latter case is shown as ensuring extremely high thermal efficiency at lower work medium temperature. The review of heat release mechanism yielded the explanation of better thermal efficiency ensured by the method in question.
