Electronic valve timing control basic description.
Electronic valve control engine.
Man energy solutions initially introduced electronic fuel injection control on its large bore me c engines which are a more compact form of their me b counterparts the me c range s electronic controls bring a whole host of advantages to the table and are characterised by.
It does this by reading values from a multitude of sensors within the engine bay interpreting the data using multidimensional performance maps called lookup tables.
A camless or free valve piston engine is an engine that has poppet valves operated by means of electromagnetic hydraulic or pneumatic citation needed actuators instead of conventional cams actuators can be used to both open and close valves or to open valves closed by springs or other means.
Depending on your car your engine control module might have other functions including idle speed control electronic valve control and variable valve timing vvt control.
Let s be a bit.
If you have four valves sometimes it only opens two.
The valves in an internal combustion engine open and close to allow both the fuel air mixture to enter the cylinder prior to combustion and to allow the exhaust gases to exit the cylinder after combustion.
The engine control module ecm also known as the engine control unit ecu monitors a vast network of sensors and actuators in your vehicle s engine bay.
Camshafts normally have one lobe per valve with a fixed valve duration and lift.
You can t do that with a regular camshaft since the.
Electronic controled valves would see an improvement in engine performance and drivability as the article suggests but rather then focusing on the reasons why it can t work.
The valves within an internal combustion engine are used to control the flow of the intake and exhaust gases into and out of the combustion chamber the timing duration and lift of these valve events has a significant impact on engine performance.
In most engines the valves are opened by lobes connected to the camshaft.
British company camcon automotive has built the first fully electronic engine valve system uncoupled from the crankshaft that offers unprecedented control over the combustion cycle.
Without variable valve timing or variable valve lift the valve timing is the same for all engine speeds and conditions.
What that does is give completely independent control over each cylinder and each valve.
