An object of the present invention is to provide a working machine and a working machine monitoring system using the same which is capable of improving the accuracy in determining fuel property. The working machine is provided with an engine operation parameter acquisition module (1041) that acquires an engine operation parameter representing the operation state of an engine mounted on the working machine; a refueling time acquisition module (1011) that acquires a refueling time when the working machine is supplied with fuel; and a fuel property determination module (1014) that determines the property of the fuel based on a comparison result of the time when the engine operation parameter changes, with the refueling time.

An engine system for a working machine includes an engine disposed in a main body of the working machine, an exhaust manifold coupled to the engine, a tail pipe, an exhaust-gas purification device disposed in the main body and including an exhaust-gas inlet-side housing. The exhaust-gas inlet-side housing includes an exhaust-gas inlet coupled to the exhaust manifold, and an exhaust-gas outlet-side housing including an exhaust-gas outlet coupled to the tail pipe. The exhaust-gas purification device is configured to purify exhaust gas discharged from the engine and to cause the purified exhaust gas to be discharged from the tail pipe to an outside of the engine system. The engine system is configured such that a silencer housing is disposable in the exhaust-gas inlet-side housing, the exhaust-gas outlet-side housing, or both, to attenuate exhaust sound of the engine.

In an engine, an intake duct is provided with an intercooler disposed downstream of an intake air compressor. An EGR pipe is provided with an EGR valve and an EGR cooler. An ECU determines a generation of a condensed water in the EGR cooler, the generation of the condensed water in a merging portion where a fresh air and an EGR gas merge with each other, and the generation of the condensed water in the intercooler. When it is determined that the condensed water is generated in any of these portions, the ECU performs a corresponding countermeasure for restricting the generation of the condensed water.

Systems and methods for correcting an engine intake camshaft position and an engine exhaust camshaft position for a variable valve timing engine are described. In one example, intake manifold pressure of an engine is sampled while a motor/generator rotates the engine at a predetermined speed without fuel being supplied to the engine. A camshaft angle where minimum intake manifold pressure is observed is a basis for correcting camshaft position.

Race car settings (e.g., Formula 1 engine mix settings) are developed for particular racing goals such as faster lap time, better acceleration, less vehicle wear, etc., using pattern templates that are derived from historical racing scenarios. The historical scenarios provide data on racing settings, racing results, and racing conditions such as squad information, equipment information, and environmental information. A cognitive (deep question answering) system can select an initial pattern template based on current racing conditions, and present suggested vehicle settings to the user (driver) using the initial pattern template. The driver can select from different candidate values for various factors, which may lead to the presentation of additional suggestions or the use of additional pattern templates. The final settings map is created based on the employed pattern templates and the driver selections.

A vehicle control system, a vehicle control method, and a storage medium are provided. A stopping process stops fuel supply to one or more stopping cylinders and supplies fuel to one or more remaining cylinders during a load operation of an engine. During execution of the stopping process, a compensating process compensates for a decrease in output of the one or more stopping cylinders due to the execution of the stopping process by increasing output generated by combustion in the one or more remaining cylinders. The system control circuit causes, when the engine rotation speed of the engine is the same, the output after being increased by the compensating process to decrease as a shaft torque of the crankshaft of the engine increases.
