What Causes Ignition Delay?

[VioletFitz]

Here are the specific reasons for ignition delay: 1. Carbon deposits or component contamination: Throttle carbon buildup can affect the sensitivity to throttle and air intake, causing delayed or incorrect signals from the computer, resulting in failure to start the vehicle; The fuel injector is prone to accumulate sticky deposits, which can obstruct normal fuel injection, leading to poor gasoline atomization, thus causing ignition delay and difficulty in starting the car. 2. Inappropriate oil viscosity: For example, at very low temperatures, high oil viscosity can slow down oil circulation and cause mechanical dry friction, making it difficult to start the car. 3. Faulty carbon canister purge valve: The evaporation effect of gasoline is particularly strong after exposure to sunlight, and poor sealing of the carbon canister valve can easily lead to cylinder flooding or wet walls.
