Electronic Valve Control Engine

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.

Electronic valve control engine.

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. Camshafts normally have one lobe per valve with a fixed valve duration and lift. In most engines the valves are opened by lobes connected to the camshaft. What that does is give completely independent control over each cylinder and each valve.

Without variable valve timing or variable valve lift the valve timing is the same for all engine speeds and conditions. The ecm is a type of electronic control unit ecu which is an embedded system that employs software to determine the required throttle position by calculations from data measured by other sensors including the accelerator pedal position sensors engine speed sensor vehicle speed sensor and cruise control switches. 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. If you have four valves sometimes it only opens two.

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. An engine control unit ecu also commonly called an engine control module ecm is a type of electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance. Let s be a bit. 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.

Electronic valve timing control basic description. 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. 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. 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.
