In one example, an operating region of the engine is broken into a plurality of zones and a misfire threshold level is dynamically provided for each of the plurality of zones based on slowly updated zone-level statistical parameters and quickly updated buffer-level parameters. The real-time dynamic misfire thresholds provide a basis for determining misfire within the engine. | 2018-03-01 |
20180058359 | FUEL-SYSTEM FAILURE DETECTION APPARATUS FOR ENGINE - There is provided fuel-system failure detection apparatus applied to an engine capable of switching between a first injection mode and a second injection mode, which comprises a first failure determination unit which performs a fuel system failure determination process while the engine is operating in the first and the second injection modes, respectively, a second failure determination unit which, when the first failure determination unit gives a decision of failure while the engine is operating in either of the two injection modes, performs the fuel system failure determination process while the engine is operating in the other injection mode, and a failure identification unit which identifies a failure in fuel systems governing the first and second injection modes respectively, based on a decision about failure given by the second failure determination unit. | 2018-03-01 |
20180058360 | METHOD FOR DIAGNOSING AND CONTROLLING TWO-STEP EXHAUST VARIABLE VALVE LIFT SYSTEM AND VEHICLE PROVIDED WITH THE SAME METHOD - Disclosed herein is a method for diagnosing and controlling a two-step exhaust variable valve lift (VVL) system, including: a controlling device acquiring an operation state signal of a vehicle; when the vehicle is in the over-run state, the controlling device outputting a mode conversion signal of the two-step exhaust VVL system; an air mass sensor measuring an air mass entering an engine, and the controlling device comparing a predetermined prediction value of the air mass with the measured air mass; when a difference of the compared air mass corresponds to a predetermined mode conversion comparing amount, the controlling device determining that a mode conversion of the two-step exhaust VVL system is completed; and when the difference of the compared air mass does not correspond to the mode conversion comparing amount, the controlling device determining that the two-step exhaust VVL system is faulty and outputting a result thereof. | 2018-03-01 |
20180058361 | METHOD FOR MONITORING AN EXHAUST-GAS SENSOR - A method for monitoring an exhaust-gas sensor in which it is determined whether at least one monitored event has occurred by evaluating at least one heat quantity supplied to and/or withdrawn from the exhaust-gas sensor during a period of time, in particular under consideration of a change in the heat quantity stored by the exhaust-gas sensor that occurs during the period of time. | 2018-03-01 |
