A crank sensor (CKP) [1] [2] [3] is an electronic device used in an internal combustion engine, both petrol and diesel, to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters.
The airflow through the crankcase and engine interior sweeps away combustion byproduct gases. This mixture of air and crankcase gases then exits, often via another simple baffle, screen, or mesh to exclude oil mist, through the PCV valve and into the intake manifold. On some PCV systems, this oil baffling takes place in a discrete replaceable ...
The crankcase often forms the upper half of the main bearing journals (with the bearing caps forming the other half), although in some engines the crankcase completely surrounds the main bearing journals. An open-crank engine has no crankcase. This design was used in early engines and remains in use in some large marine diesel engines.
Crankshaft, pistons and connecting rods for a typical internal combustion engine Marine engine crankshafts from 1942. The crankshaft is located within the engine block and held in place via main bearings which allow the crankshaft to rotate within the block. [3] The up-down motion of each piston is transferred to the crankshaft via connecting ...
This article presently has the flowing text: Some engines, such as GM's Premium V family, use crank position sensors which read a reluctor ring integral to the harmonic balancer. This is a much more accurate method of determining the position of the crankshaft, and allows the computer to determine within a few degrees the exact position of the ...
Modern engines usually use a crank sensor directly connected to the engine management system. The term can also be used to describe the tick marks along the length of an optical mark recognition sheet, used to confirm the location of the sheet as it passes through the reader. See, for example, U.S. Patent 3,218,439 (filed 1964, granted 1965 ...
Diagram of a crankcase scavenged valveless 2-stroke engine in operation. Some SI engines are crankcase scavenged and do not use poppet valves. Instead, the crankcase and the part of the cylinder below the piston is used as a pump. The intake port is connected to the crankcase through a reed valve or a rotary disk valve driven by the engine. For ...
A harmonic damper is a device fitted to the free (accessory drive) end of the crankshaft of an internal combustion engine to counter torsional and resonance vibrations from the crankshaft. This device must be an interference fit to the crankshaft in order to operate in an effective manner.
