What Happens When a Car Igniter Fails?
3 Answers
When a car igniter fails, it can lead to difficulties in starting the car and unstable idle speed during startup. The igniter is a device capable of providing sufficient energy in an instant to ignite coal dust or oil fuel and stabilize the flame. It is a system in the vehicle that starts the engine, functioning to connect or disconnect the primary circuit of the ignition system based on the ignition signals input from the signal generator, thereby generating the ignition high voltage in the secondary winding of the ignition coil. The car igniter mainly consists of the power source, ignition coil, distributor, ignition switch, spark plug, additional resistor and its short-circuiting device, as well as high and low voltage wires.
Yesterday my car's ignition system failed, causing the engine to stall abruptly. It sputtered like sneezing, with the lights flickering a few times before dying during startup – really startled me. On the road, acceleration was weak with intermittent power loss, swaying like a drunk. Worse, it suddenly stalled at a red light intersection, nearly causing a rear-end collision – absolutely terrifying. Later I learned ignition failure leads to excessive exhaust emissions, can damage spark plugs, and drastically increases fuel consumption, hurting your wallet. I rushed to my friend's garage for inspection and replaced the faulty parts. Advice to car owners: address such issues promptly, don't delay.
Hey, ignition problems can be a real headache. Last time I saw a car start with an unstable engine, acceleration as slow as a snail, and severe body shaking, which seriously affected handling. Even worse, the engine might stall, making it extremely dangerous at intersections or on highways. Don't underestimate a faulty ignition—after the spark plugs wear out, fuel consumption can increase by 15%, and the catalytic converter might also be ruined, doubling repair costs. It's recommended to check the fuses and wiring first. If you're handy with simple tools, try replacing parts yourself; otherwise, head to a professional shop quickly to prevent a small issue from becoming a big one.
