A distributor less system with waste spark.
Dwell control is typically defined by the engine's ignition system. The dwell angle is the duration in crankshaft degrees during which the ignition points are closed. This setting affects the timing of the spark, influencing engine performance and efficiency.
The tachometer is an electrical device that senses the ignition system. It indicates engine RPM (revolutions per minute). Engine rpm and crankshaft rpm are two ways of expressing the same thing. True, the crankshaft does rotate twice for each complete set of cylinder firings but the tachometer counts each rotation.
A rotation of 270 degrees clockwise is equivalent to a rotation of 90 degrees counterclockwise. In a Cartesian coordinate system, this means that a point originally at (x, y) will move to (y, -x) after the rotation. Essentially, it shifts the point three-quarters of the way around the origin in the clockwise direction.
crankshaft sensoryes because if the ecm isn't getting a signal from the sensor it doesn't know at what orientation the crankshaft is and won't let the ignition system start the engine. that's how i understand it to work
the starter motor on just about any engine is very close to the crankshaft. the easiest way to find it is to follow the wires of the ignition system (usually yellow, sometimes black, it depends) the ignition system is directly connected to the starter.
Timing marks are generally found on the flywheel or crankshaft pulley. This indicator is used to set the timing of an engine's ignition system.
the purpose is to ignite the fuel /air mixture at such a time that the resulting burn causes expansions of the gases which forces the piston down and so turns the crankshaft.
From Wikipedia on Uranus: Uranus's axis of rotation lies on its side with respect to the plane of the solar system, with an axial tilt of 97.77 degrees. -PlutoLover101
The "engine timing mechanism" is a system of gears and belts(or chains) that keep the rotation of the crankshaft synchronized (timed) with the cam shaft so they operate at the same intervals.
Code 22 on a 1993 Oldsmobile 88 typically indicates a problem with the vehicle's ignition system, specifically relating to the crankshaft position sensor or the ignition module. This code can lead to issues such as poor engine performance or stalling. To resolve the issue, you may need to inspect and possibly replace the crankshaft position sensor or related ignition components. It's advisable to use a diagnostic scanner to confirm the code and guide repairs.
a primary advantage of the electronic ignition system over conventional ignition system is?
ECU received signal from crankshaft position sensor and deliver asignal to ecu then change the signal to coil then tranfers to spark plug
