Electronic Valve Control Engine

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 valve control engine. 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. 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. If you have four valves sometimes it only opens two.

What that does is give completely independent control over each cylinder and each valve. 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 timing control basic description. 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.

On top of. 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. 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. You can t do that with a regular camshaft since the.

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. 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. In most engines the valves are opened by lobes connected to the camshaft.
