The compressed gas then becomes the spring, so to speak, but does not have the same traits as springs do at elevated rpm. A small light spring is sometimes fitted between the piston and retainer so that when the system is switched off the spring forces the piston down against the bottom of the bore, thus forcing the retainer upwards. This ...
At the time, warming the car in the winter made sense since it could take several minutes for the right air-fuel mix to reach the engine, without which the vehicle was at risk of stalling or ...

Cutaway of a dual overhead camshaft engine 1969 AMC V8 overhead valve engine. The rocker cover has been removed, so the pushrods, rocker arms, valve springs, and valves are visible. A valvetrain is a mechanical system that controls the operation of the intake and exhaust valves in an internal combustion engine. [1]
Stiffer valve springs can help prevent valve float and valve bounce but at the expense of increased friction losses, higher stresses, and more rapid wear in the valvetrain. Various techniques have been used to offset the effect of stiffer springs, such as dual-spring and progressive-sprung valves, roller-tipped tappets, and pneumatic valve ...
"Bottoming" can be caused by the suspension, tires, fenders, etc. running out of space to move, or the body or other components of the car hitting the road. Control problems caused by lifting a wheel are less severe, if the wheel lifts when the spring reaches its unloaded shape than they are, if travel is limited by contact of suspension ...
It is a result of snow, ice, water, loose material and the texture of the road surface on the traction produced by the wheels of a vehicle. [ 1 ] Road slipperiness can be measured either in terms of the friction between a freely-spinning wheel and the ground, or the braking distance of a braking vehicle, and is related to the coefficient of ...
Cadillac Eldorado cold start. A cold start is an attempt to start a vehicle's engine when ambient temperatures are much lower than its normal operating temperature. [1] A cold start can be difficult for an engine due to higher viscosity of oil and fuel in cold temperatures.
