Cold cranking simulator
| Oil glossary |
An intermediate shear rate viscometer that predicts the ability of an oil to permit a satisfactory cranking speed to be developed in a cold engine.

Intermediate, английский
- Between two others.
- Промежуточный
- Промежуточное звено
- Chemical term for an igneous rock containing 54 to 62% silica and usually
Viscometer, английский
- A device for determining viscosity; esp. used to measure the viscosity of slurries, including fresh concrete.
- A device designed to measure the viscosity (resistance to flow) of the fluid. many types exist from simple calibrated glass tubes to extensively instrumented, on-line shear viscometers.
Satisfactory, английский
Удовлетворительный

Collapse pressure, английский
The minimum differential pressure that an element is designed to withstand without permanent deformation.
Coefficient of friction, английский
- The number obtained by dividing the friction force resisting motion between two bodies by the normal force pressing the bodies together.
- Коэффициент трения
- The ratio of the force causing a body to slide along a plane (in the direction of sliding) to the normal force pressing the two surfaces together.
- The number obtained by dividing the force that resists motion between two bodies by the normal force that brings the bodies together (see static friction, dynamic friction, stick-slip ratio). coefficient of friction – the force required to move one body over a horizontal surface at constant speed divided by the weight of the body. for example, if a force of 4kg is required to move a body weighing 10 kilograms, the coefficient of friction is 0.4. coefficient of friction of solids is independent of load. coefficient of friction of liquids is a function of the viscosity of the fluid, speed and pressure of the application.
- The factor used to determine the maximum tractive effort which can be applied by a locomotive under a given rail condition before slip occurs. it is denoted by the greek letter µ and may vary between 0.1 and 0.4 in uk conditions.
