Abstract: Although modern diesel fuel formulations are intended to reduce emissions of diesel engines, at least some of those modern fuels tend to have relatively low lubricity levels. The control valve assemblies described herein help to minimize any increased wear that would otherwise result from the use of such low lubricity fuels by providing a valve element, a valve guide, and an insert. The valve element is received within the valve guide and is moveable between an open position and a closed position. The insert forms a first sealed interface and a second sealed interface with the valve element and the valve guide. When the valve element is in the closed position, both of the first sealed interface and the second sealed interface are engaged. When the valve element is in the open position, only one of the first sealed interface and the second sealed interface is engaged.

Abstract: A process for detecting an aluminum-based material deposited onto a titanium-based gas turbine engine component during engine operation is disclosed. The process comprises immersing at least a portion of the titanium-based component, which has been subjected to engine operation, into an acid solution to form an etched component. The acid solution comprises sodium fluoride, sulphuric acid and water. The etched component may then be removed from the solution and visually inspected for dark areas in contrast to light areas, the dark areas indicating deposited aluminum-based material.

Abstract: In a spark ignition engine, a thermal insulation thin layer is formed over a wall surface, facing an inside of a combustion chamber, of a base material forming the combustion chamber, and for a thermal conductivity λ [W/(m·K)], a thermal diffusivity κ [mm2/s], and a thickness L [μm] of the thermal insulation thin layer, L≧16.7×λ and L≦207.4×(κ)0.5 are satisfied. With such a configuration, a heat loss Q_total escaping from gas in a cylinder to the wall of the combustion chamber over all strokes can be reduced, and the thermal efficiency can be improved without inducing degradation of knocking due to an increase in an amount of heating Q_intake of the gas in the cylinder during an intake stroke.
