Title: Method for controlling engine disorder by using dieseling mode for a lpg engine
Inventor: CHO SEONG HO
IPC: F02M21/00
Filed: 2000-12-28
Abstract: PURPOSE: A power latch time is made constant in a dieseling mode control logic, thereby reducing exhaust gas in an LPG engine. CONSTITUTION: An engine control method comprises setting a power latch time by a scrapping area and a coolant temperature detected by a coolant temperature sensor in ignition off.
