Keywords: transport engines, cylinder heads, cyclic load, durability, reliability.

A method is offered to evaluate fatigue resistance of transport engine cylinder head taking account of application-specific thermal and mechanical cyclic loads.

Keywords: rotary engine, design, indicated and effective parameters.

The article discloses design principle and operation of four-chamber rotary engine. Engine mathematical model as well as calculations of indicated and effective parameters are provided.

Keywords: dual fuel engine, charge system, gas accumulator, reduction of toxic emission.

Dual fuel engine type KAMAZ-7409 was tested in two versions: standard one and one added with a gas accumulator. Influence of a gas accumulator on engine fuel efficiency and environment performance was scrutinized.

Keywords: turbocharger components, Lloyd's Register of Shipping, failure statistics.

The authors analyze turbocharger failures in propulsion and auxiliary marine engines based on statistics borrowed from Lloyd's Register of Shipping's database.

Keywords: transport engines, fuel systems, UN ECE Regulation 96-02, optimization, certification test.

KAMAZ engines for non-road applications have been studied for compliance with UNECE Regulation 96-02. This was achieved through optimization of common rail fuel system and type S300G turbocharger. Certification test demonstrated compliance with applicable emission regulations.

Keywords: motor transport, growth rate, traffic volume, air quality.

The article offers the analysis of automobilization level, growth of the amount of motor vehicles and traffic volume in Saint-Petersburg. The analysis of air quality was carried out as well. Trend to improvement of air quality in Saint-Petersburg is demonstrated.

Keywords: gasoline engines, detergent additives, stand test, efficiency, environmental performance.

A method is offered for evaluation of gasoline detergent additive for efficiency based on initial (reference) level of deposit on combustion chamber surfaces. A number of detergent additive types were tested on a motor stand for environmental performance.

Keywords: tractor diesel engine, stand test, alimentation system, ethanol vapour, fuel efficiency and environmental performance.

Tractor diesel engine with ethanol vapour injection into air receiver was tested on a motor stand. Engine power, fuel efficiency and environmental performance were determined as functions of engine load and speed.

Keywords: diesel engine, gas engine, air pollution control, control components.

The review covers engine controls and devices targeted at the achievement of compliance with future emission regulations. These include, inter alia, control of exhaust gas recirculation rate, cylinder pressure sensor, and controls of SCR (Selective Catalytic Reduction) system.
