Method for preventing abnormal consumption of engine oil due to excessive intake negative pressure in a vehicle

摘要

The present invention relates to an ignition control device of a vehicle for controlling ignition timing by detecting knocking generated by each cylinder by attaching a knocking detection unit to each spark plug after installing an ignition coil. Spark plug 1 for igniting each cylinder in order, each ignition coil 2 for igniting each spark plug 1 by supplying current under the control of an electronic control unit (ECU), and each ignition coil The vehicle's ignition control device is composed of a knock detection unit (3) mounted in (2) to detect when knocking occurs in each cylinder and send a signal to the electronic control unit to control the current supply timing of each ignition coil 2. .
