摘要： An engine controller, for an internal combustion engine, is configured to:
control at least one actuator to provide an air-fuel mixture with a lambda value higher than 3 to a main combustion chamber via at least one intake valve, wherein the at least one actuator is arranged upstream of at least one intake port or which is arranged in the intake port;
control at least one fuel supply system to provide fuel directly to the main combustion chamber and/or a pre-combustion chamber of a piston-cylinder unit such that at the time of ignition of the air-fuel mixture the lambda value of that air-fuel mixture in the main combustion chamber is lower than the lambda value of the air-fuel mixture provided to the main combustion chamber via the at least one intake valve.-

摘要： Methods and systems for fault identification and mitigation in an engine system. A state observer obtains current state information from the engine system, and a feature calculator uses data obtained from the state observer to calculate one or more feature indicators, which are monitored by a health estimator for the occurrence of a change using one or more change probability models. When the health estimator identifies a change, a fault isolator determines a component of the engine system that is subject to fault or health deterioration.

摘要： A supplemental fuel system includes a supplemental fuel tank, an electronic valve, a temperature sensor, and a controller. The supplemental fuel tank is configured to store a supplemental fuel configured to supplement a primary fuel used by an engine. The electronic valve is configured to be positioned between the supplemental fuel tank and an air supply system for the engine. The temperature sensor is configured to acquire temperature data regarding a temperature of the engine. The controller is configured to control the electronic valve such that the electronic valve is (i) closed to prevent the supplemental fuel from being provided to the air supply system in response to the temperature being less than a temperature threshold and (ii) open or openable to permit the supplemental fuel to be provided to the air supply system in response to the temperature being greater than the temperature threshold.

摘要： Methods and systems are provided for EGR valve diagnostic. In one example, a method includes providing a correction to a position of the EGR valve to compensate for an altitude of the vehicle. The compensation is based on a comparison of a pressure ratio to a curve rationalized with a barometric pressure.

摘要： A controller is configured to control an internal combustion engine. The internal combustion engine may execute multi-shot injection and single-shot injection and execute a deactivating process that stops supplying fuel to at least one of cylinders and supplies fuel to the remaining cylinders. The controller is configured to execute, when terminating the deactivating process to restart supplying fuel to a deactivated cylinder in which supply of fuel is stopped, a retarding process that executes a first fuel injection through the single-shot injection and retards a fuel injection start timing as compared to when executing the multi-shot injection.

摘要： System and methods for an internal combustion engine are described. In one example, the internal combustion engine includes one or more engine cylinders having igniters that include a pre-chamber. One or more of the engine cylinders may be operated in a skip-fire mode if a cylinder misfires or if the internal combustion engine is cold started.

摘要： A method for operating a spark-ignition internal combustion engine, wherein the internal combustion engine is operated using hydrogen as fuel, a lambda injection value is a value that indicates the formation of a mixture on the basis of an injection fuel quantity (Finjection) to be supplied to a combustion chamber of the internal combustion engine and an air quantity (L) to be supplied to the combustion chamber from outside of the internal combustion engine, wherein the injection fuel quantity (Finjection) is determined, at least in some ranges, independently of a lambda target value. In order to ensure adequate operation of hydrogen engines, the injection fuel quantity (Finjection) is determined, at least in some ranges, at least on the basis of the air quantity (L).

摘要： A method of operating a vehicle with a hybrid powertrain comprising an electrical drivetrain and an internal combustion engine includes detecting that a temperature of a selective catalytic reduction (SCR) device of an aftertreatment system of the vehicle is below a particular temperature; directing the electrical drivetrain to fulfil a vehicle drive load; and while the electrical drivetrain is fulfilling the vehicle drive load and the temperature of the SCR device is below the particular temperature, operating the internal combustion engine to generate airflow for transport of heat through the aftertreatment system and directing a heat source to raise a temperature through the SCR device of the aftertreatment system. The internal combustion engine can be operated in idle to spin the internal combustion engine to generate the airflow while the electrical drivetrain fulfils the vehicle drive load.
