On March 31, GM announced it was going to recall over 1.5 million more cars of six different models, due to faulty power steering. Of these, over 1.3 million were in the United States, and three of the models were also involved in the faulty ignition recall. The total number of cars recalled during 2014 as of 1 April was 6.26 million. [6]
When it goes wrong, it stops transmitting the signal which contains the vital data for the ignition and other parts in the system. A bad crank position sensor can worsen the way the engine idles, or the acceleration behaviour. If the engine is revved up with a bad or faulty sensor, it may cause misfiring, motor vibration or backfires.
Older distributor designs used a cam on the distributor shaft that operates the contact breaker (also called points). Opening the points causes a high induction voltage in the ignition coil. [ 1 ] This design was superseded by an electronically controlled ignition coil with a sensor (usually Hall effect or optical) to control the timing of the ...
Four spark plug wires (distributor end on the right, spark plug end on the left) Spark plug wires (also called high tension leads) are electrical cables used by older internal combustion engines to transmit high-voltage electricity from the distributor to the spark plugs. Tension in this instance is a synonym for voltage. High tension may also ...
In spark-ignition internal combustion engines, knocking (also knock, detonation, spark knock, pinging or pinking) occurs when combustion of some of the air/fuel mixture in the cylinder does not result from propagation of the flame front ignited by the spark plug, but when one or more pockets of air/fuel mixture explode outside the envelope of the normal combustion front.
Among the referral deals Sheller had made was one with Hilliard, a charismatic litigator who had won headline verdicts in cases ranging from defective cars to formaldehyde in the FEMA trailers used to house Hurricane Katrina victims. Lately, Hilliard has been in the news as a lead lawyer in the General Motors faulty ignition switch cases.
Common causes of backfire are running rich (too much fuel going into cylinders) or faulty ignition, possibly a fouled (dirty) spark plug, coil, or plug wire. Pop-backs are usually caused by problems with timing. If the timing is too early, the spark plug fires before the intake valves close, causing the combustion to propagate into the intake ...
Pre-ignition and engine knock both sharply increase combustion chamber temperatures. Consequently, either effect increases the likelihood of the other effect occurring, and both can produce similar effects from the operator's perspective, such as rough engine operation or loss of performance due to operational intervention by a powertrain ...
