Abstract: An engine is provided which includes an oil gallery, a base attaching seat in an engine frame wall, and a base for component mounting attached to the base attaching seat. An oil cooler and an oil filter are mounted on the base for component mounting, and the base attaching seat is provided with an oil inlet communicating with an upstream-side passage of the oil gallery, and an oil outlet communicating with a downstream-side passage of the oil gallery. Attaching the base for component mounting to the base attaching seat allows engine oil flowing into the oil inlet of the base attaching seat from the upstream-side passage of the oil gallery to pass the base for component mounting, the oil cooler, and the oil filter, and flow out of the oil outlet of the base attaching seat to the downstream-side passage of the oil gallery.

Abstract: There is provided an engine exhaust treatment device in which stick of a nozzle portion of a urea water injector can be suppressed. The engine exhaust treatment device includes: an SCR catalyst case housing an SCR catalyst; an SCR exhaust inlet pipe; and the urea water injector and the nozzle portion of the urea water injector is directed toward an inside of the SCR exhaust inlet pipe. An exhaust deflector is provided in the SCR exhaust inlet pipe and the exhaust deflector is mounted to an inner peripheral face of the SCR exhaust inlet pipe on an exhaust upstream side of the urea water injector so that exhaust flowing toward the nozzle portion of the urea water injector is deflected by the exhaust deflector and diverted from the nozzle portion.

Abstract: In a direct injection diesel engine, front and rear intake openings of each cylinder are arranged along the row direction of the cylinders on one side thereof. A front intake port communicating with the front intake opening is formed to extend from the front intake opening in a direction generally perpendicular to the row direction of the cylinders. A rear intake port communicating with the rear intake opening is formed to be directed to a flow direction of a swirl generated in the corresponding combustion chamber.

Abstract: An exhaust purification device incinerates particulates, collected by the DPF, always in an appropriate combustion state, thereby surely regenerating a DPF without melting down the DPF. An ECU of the device estimates the amount of the particulates collected by the DPF (S6), selects a map according to whether the collection amount is appropriate or excessive (S8), determines a target oxygen amount from a DPF temperature on the basis of the selected map (S10 and S12), and feedbacks the oxygen amount in exhaust gas to the target oxygen amount (S20). Since the particulate collection amount is reflected in control of the oxygen amount, the particulates can be incinerated always in the appropriate combustion state regardless of the particulate collection amount.

Abstract: An exhaust emission control device having a deposit amount detecting section for detecting a deposit amount correlation value Qpm of the particulate matter captured by a diesel particulate filter, a temperature detecting section for detecting a temperature correlation value Tdpf of the particulate filter, and a correction section for correcting the target idle rotating speed Ni to the higher rotating speed to suppress overheating of the diesel particulate filter in accordance with detection results of the deposit amount detecting section and the temperature detecting section.

Abstract: A gaseous fuel filling structure includes a coupler connected to a gaseous fuel supply system, a gaseous fuel cylinder that stores a gaseous fuel at a high pressure, a fuel dissipation preventing device that prevents dissipation of the gaseous fuel, and a switching device that is selectively placed in a first state in which the coupler is connected to the gaseous fuel cylinder and disconnected from the fuel dissipation preventing device, or a second state in which the coupler is connected to the fuel dissipation preventing device. The switching device includes a member(s) for preventing back flow of the gaseous fuel from the gaseous fuel cylinder toward the coupler.
