Backup camera view on the navigation screen of a Lexus IS 250 Backup camera on a Volkswagen Golf Mk7 hidden inside the logo. A backup camera (also called a reversing camera or rear-view camera) is a video camera specifically designed to be attached to the rear of a vehicle to aid in reversing and reduce the rear blind spot.
Engines that always run at a relatively high speed, such as race car engines, will have considerable overlap in their valve timings for maximum volumetric efficiency. Road car engines are different because they are required to idle at less than 1000rpm, and excessive valve overlap would make smooth idling impossible because of the mixing of ...
The cam can be seen as a device that converts rotational motion to reciprocating (or sometimes oscillating) motion. [clarification needed] [3] A common example is the camshaft of an automobile, which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.
The cams open (lift) the valves kind for a certain amount of time (duration) during each intake and exhaust cycle. The timing of the valve opening and closing, relative to the position of the crankshaft, is important. The camshaft is driven by the crankshaft through timing belts, gears or chains.
A camshaft operating two valves. A camshaft is a shaft that contains a row of pointed cams in order to convert rotational motion to reciprocating motion.Camshafts are used in piston engines (to operate the intake and exhaust valves), [1] [2] mechanically controlled ignition systems and early electric motor speed controllers.
For twin-cam or DOHC engines, VCT was used on either the intake or exhaust camshaft. (Engines that have VCT on both camshafts are now designated as Ti-VCT.↓) The use of variable camshaft timing on the exhaust camshaft is for improved emissions, and vehicles with VCT on the exhaust camshaft do not require exhaust gas recirculation (EGR) as retarding the exhaust cam timing achieves the same ...
"Does he not see me, my lead is right there literally right in front of me," teased someone else, as if reading the Newfie's mind. How to Tell Your Dog It’s Time for a Walk.
As many as 50 small children are killed by SUVs every year in the USA because the driver cannot see them in their rear-view mirrors. [8] Camera systems are usually mounted to the rear bumper or lower parts of the car, allowing for better rear visibility. [citation needed] Aftermarket secondary rear-view mirrors are available. They attach to the ...
