Spark timing in an internal combustion engine is primarily controlled by the engine's electronic control unit (ECU) based on various inputs. These inputs include engine speed (RPM), load, temperature, and throttle position, which help the ECU optimize ignition timing for performance, efficiency, and emissions. Additionally, advanced systems may use knock sensors to adjust timing dynamically to prevent engine knock. Overall, the goal is to achieve the best possible combustion for power output and fuel efficiency.
What else can I help you with?
What controls the spark timing on 2000 2.2 s10?
The ECM controls the timing with information sent to it from sensors such as the crank sensor and the knock sensor.
What does an ignitor unit assembly do on a 2002 Yamaha vstar 1100?
The ignitor unit controls the signal from the magnito to the ignition coils. This in turn controls the spark to the spark plugs and also controls the timing of the firing of the spark plugs in proper sequence.
What controls distributor advance on a 1987 Chevy 305 TBI engine?
Distributor Advance is the wrong term; the Distributor Advance system implies actually moving the timing components of the distributor to control timing of spark in the engine (A Vacuum Advance, is an example of this). Modern controls use computer spark mapping, through learned routines or factory set timing models to control the spark based on these tables, through the computer. In all essence it is the computer that controls all spark functions.
How do you time a 1994 Cadillac Fleetwood 5.7 motor?
The 5.7 in your Cadillac is a Chevrolet LT1. The same motor that came in an Impala SS and Buick Roadmaster. It uses an "OPTI SPARK" distributor that runs off the front of the motor. There is no timing adjustment that can be made with the unit. The engine management computer controls the timing and adjusts the spark as ou drive. If you are having timing problems, the OPTI SPARK needs to be replaced.
1994 Ford Probe GT has no spark fuel cut off switch is fine distributor is fine what else is there?
Did you check your coil? and stupid question, but did you check the timing belt. and i believe it has a cam sensor, that controls spark.
Do you need to adjust the timing when you change the spark plugs?
there is no timing when you change the spark plugs the car adjusts itself
Will a 1993 stealth run without the ECM?
Nope. The engine computer controls everything from spark timing to fuel/air mixture. There's no way you'll get it to run without it.
What controls timing on 96 Cherokee?
The engine computer is in charge of timing.
What does the ECM in 1991 Dodge Colt Vista do?
ECM means Engine Control Module. It is the car's computer and controls ignition, spark, timing, emissions etc. A vital part of the car.
What is the firing order of mercidez actross v6 diesel engine?
There is no firing order on a diesel engine as it has no spark plugs to fire. The valve timing controls the sequence at which the cylinders ignite the fuel.
What does the module do in the distributor?
It controls spark and fuel.
Why won't a 1978 Corvette idle?
Check the spark. If that's good check compression and timing. Check the spark. If that's good check compression and timing.
