The utility model discloses a kind of top-mounted vehicle-mounted air conditioners, including the roof body of the air conditioner cowling assembly being provided with air conditioner outer machine on inside, air conditioner outer machine includes shell, condenser and evaporator assembly arranged in parallel with the parallel arrangement of roof body are arranged in shell, evaporator assembly is equipped with condensate water flow guide structure;With the position of evaporator assembly corresponding roof body and shell between pad plate are equipped, pad plate and air conditioner cowling assembly are connected together, and air circulation communication structure is equipped between air conditioner cowling assembly and evaporator assembly;With the position of condenser corresponding shell and roof body between spacing, and multiple flow-through holes are equipped on shell. The thickness of air conditioner outer machine is small, the height of whole vehicle is reduced, the passability is guaranteed, and the removal effect of condensate water is improved;Air conditioner cowling assembly realizes small-size design, not only guarantees the normal circulation flow of air, but also reduces the space occupancy rate in vehicle, is convenient to disassemble and repair and maintenance.

This application discloses a burner and a cooktop, belonging to the technical field of gas stoves. The burner includes a main body and a fan assembly. The main body has a gas blowing channel, at least one flue gas recirculation channel, and multiple flame outlets. The gas blowing channel has a first inlet and a first outlet. The flue gas recirculation channel has a flue gas recirculation port and a flue gas outlet. The first inlet is connected to the flue gas outlet, and the first outlet is connected to at least some of the flame outlets. The first outlet, the flue gas recirculation port, and the flame outlets are all upward-facing. At least a portion of the fan assembly is disposed within the main body. The fan assembly is used to form an airflow from the first inlet to the flame outlets within the gas blowing channel. This embodiment can extend the residence time of the flue gas generated by the burner, thereby improving the heat exchange effect between the flue gas and the bottom of the cookware, and thus improving thermal efficiency.

This invention discloses a control method for a piston cooling spray hook, relating to engine control technology. The method involves acquiring the engine's oil pressure and temperature, and combining these to obtain a first oil flow requirement for the oil pump. A second oil flow rate for the piston cooling spray hook is calibrated based on the engine's real-time throttle opening, and the change in oil flow rate of the piston cooling spray hook is obtained based on the change in the second oil flow rate. This change in oil flow rate is then superimposed on the first oil flow requirement to obtain a target flow requirement. Finally, the oil pump is controlled to output an oil flow rate consistent with the target flow requirement. This invention achieves coordinated control of the oil pump flow rate and the piston cooling spray hook flow rate, ensuring lubrication and cooling functions are met under high loads, while reducing oil flow rate and decreasing the driving power of the oil pump under low loads.
