Engine Oil Thickening in High-Speed Passenger Car Service

The role of cylinder bore shapes in engine performance has been the subject of several studies in recent years. In particular, the influence of bore distortion on oil consumption under high speed conditions has generated significant interest. In this paper, the effect of an axial bore profile on radial dynamics of a ring is investigated. Radial ring motions within grooves due to the axial bore profile can generate significant inertial effects and also have an impact on ring end-gap sizes and lubrication conditions at the ring-liner interfaces. The magnitude of such effects is dependent on the ring-pack configuration, engine operating conditions (speed and load) and axial bore profile details. These issues are investigated in this study due to their implication on engine oil consumption, friction and blow-by. The authors have developed an analytical expression to account for the effects of radial ring inertia due to an axial bore profile for implementation in a piston ring-pack simulation tool RINGPAK. Simulation results from a gasoline engine study are presented to illustrate the effects of engine speeds, ring tensions, and characteristics of axial bore profiles on ring radial dynamics and ring-liner lubrication. Relevant qualitative comparisons are made to experimental measurements available in the literature.

Further Development

This paper is a review of the design and characteristics of an overhead-camshaft, hemispherical head engine, particularly in respect to the production of an economical power unit for passenger car use. The reasons for adoption of this particular design are discussed and the difficulties encountered during the development of these particular engines are mentioned. An analysis of the engine on the test brake is given, and a comparison is made with contemporary engines. Finally, a section is devoted to the further development of a basically touring car engine for high-speed competition events. The MS. of this paper was received at the Institution on 27th February 1953. For the minutes of the meeting in London on 14th April 1953, at which this paper was presented, see p. 118.

Abstract A significant part of the fleet of passenger cars in operation on Russian railways are equipped with an autonomous power supply system, in which the main source of energy is an undercar generator, which is rotated from the axle of a wheelset. The disadvantage of such a system is the limitation of the speed range in which it is possible to power consumers of electric power of a passenger car from the main source: as a rule, the lower limit of this range is 35 km/h. The article proposes a variant of a technical solution that will expand the speed range of using the undercar generator by lowering the lower limit to 25 km/h: it is proposed to provide self-excitation of the undercar generator through an inverting-type DC voltage pulse converter. The parameters of the elements of the pulse converter circuit and the possibility of expanding the boundaries of the high-speed range of operation of the EGV.08.1U1 undercar generator are estimated.

The aim of this research is to investigate the usage of passenger car engine oil into a motorcycle engine by determining the after effect of the lubricant to the engine. The difference between engine oil of passenger car and motorcycle is the friction modifier that is in the formulation of cars engine lubricant. A motorcycle engine has a wet clutch system in the crank case, such engine oil with a friction modifier will decrease the clutch capacity of the system. In this study, three types of methodology tests have been conducted such as endurance test which combined with the fuel efficiency test at the same time, drag test and Ferrography tests that were conducted to determine the amount of contamination in both types of engine oil. The results showed that using a passenger car lubricant on motorcycle engine did not affect the engine compartment and parts. The numbers of metal wear in the used oil of both types of cars and motorcycle were slightly different.
