An abnormality assessment device includes an on-off valve that shuts an intake path on an upstream side of a connection portion of a breather line with respect to the intake path and an abnormality assessment element that assesses abnormality of the breather line. The abnormality assessment element assesses abnormality of the breather line based on a difference between an intake flow rate that is detected by an intake flow rate sensor and a target intake flow rate in a case where the on-off valve is closed.

Fuel injection control of an engine is executed by setting a required injection amount and an air-fuel ratio correction amount.

Methods, systems and devices for evaluating incoming air to an engine, industrial controller including engine controls, valves and solenoids, for concentrations of explosive or combustible gases or vapors, and actuating process control including but not limited to shutting down an engine or other industrial process to control an outcome including the prevention of an overspeed condition when pre-set or calculated elevated gas or vapor concentrations are detected. In some embodiments industrial control including engine shutdown may be achieved conventionally via an electronic kill signal, a shutdown of the fuel injector, carburetor or fuel pump, and in emergency conditions by the shutoff of incoming air to an air intake, turbocharger, or other air delivery systems. Decisions based on explosive gas or vapor concentrations and species and the use of networking to allow additional systems to take action before explosive gases or vapors reach said other valve-sensor devices can provide additional safety.

A system that controls a combustion engine stores network vectors in a memory that represent diverse and distinct spiking neural networks. The system decodes the network vectors and trains and evaluates the spiking neural networks. The system duplicates selected network vectors and crosses-over the duplicated network vectors that represent modified spiking neural networks. The system mutates the crossed-over duplicated network vectors by randomly modifying one or more portions of the crossing-over duplicated network vectors. The system meter exhaust gas into an intake manifold when an engine temperature exceeds a threshold, an engine load exceeds a threshold, an engine's rotation-per-minute rate exceeds a threshold, and a fuel flow exceeds a threshold. The system modifies fuel flow into an engine's combustion chamber on a cycle-to-cycle basis by the trained spiking neural network.

A driving force control device for a vehicle is provided, which includes a motor, an engine, and a controller. The controller sets a target torque of the vehicle corresponding to accelerator operation, and distributes a target engine torque according to a distribution rule defined beforehand, based on the target torque of the vehicle, and outputs a control signal corresponding to the target engine torque to the engine. The controller estimates a future amount of intake air to a cylinder based on the target engine torque, and estimates a torque of the engine in the future based on the estimated future amount of intake air. The controller sets a target motor torque based on the estimated torque of the engine so that the target torque of the vehicle is achieved in the future, and outputs a control signal corresponding to the target motor torque to the motor.

During a predetermined operation state in which the opening degree of a throttle valve is fixed, an air flow meter positioned more on the upstream side than a pressure control valve detects a first intake air amount when the opening degree of the pressure control valve positioned on the upstream side of the throttle valve is set to a predetermined first valve opening degree and a second intake air amount when the opening degree of the pressure control valve is set to a predetermined second valve opening degree smaller than the first valve opening degree. On the basis of the first intake air amount and the second intake air amount, a diagnosis is made regarding whether there is an abnormality in a first pipe, a second pipe, a third pipe and the like which are included in a blow-by gas recirculation system for blow-by gas treatment.

A system and method for monitoring vehicle performance and updating engine control parameters, which provides a solution to the problem of tuning engine control parameters for a vehicle. The core components of the invention are an engine controller coupled to an interface device which communicates with a remote device. Generally speaking, the components are configured as follows: the engine controller receives signals from various sensors in a vehicle and the engine controller controls the engine based on engine control parameters and the signals from the sensors. The interface device monitors the engine control and sensor signals and transmits information to the remote device. The remote device receives the information and sends back updated engine control parameters. The interface device receives the updated engine control parameters and communicates with the engine controller to update the engine control parameters using the updated engine control parameters.
