A burner supporting primary and secondary combustion reactions may include a primary combustion reaction actuator configured to select a location of the secondary combustion reaction. A burner may include a lifted flame holder structure configured to support a secondary combustion reaction above a partial premixing region. The secondary flame support location may be selected as a function of a turndown parameter. Selection logic may be of arbitrary complexity.

A powertrain includes an engine that has a crankshaft. A first motor-generator is drivingly connected to the crankshaft via an endless rotatable device. The powertrain includes a transmission that has a transmission input member driven by the crankshaft and a transmission output member. A front differential is operatively connected with front half shafts. A transfer case has a gearing arrangement configured to distribute torque of the transmission output member to the front differential and to a driveshaft. A rear differential is operatively connectable with the driveshaft, and is configured to transfer torque from the driveshaft to rear half shafts. A second motor-generator is drivingly connected to the rear differential. A controller is operatively connected to the second motor-generator, and controls the second motor-generator to function as a motor that provides torque to the rear wheels through the rear differential. A modular rear drive unit operatively connects to the vehicle body.

A suspension device for an in-wheel motor driven wheel ensures a lever ratio and stroke of a shock absorber without setting the upper end portion of the shock absorber at a high position. A wheel driven by an in-wheel motor unit is suspended on a vehicle body via a suspension structure member and a shock absorber, the suspension structure member including an upper suspension arm pivotally supported with respect to the vehicle body, and a third link. The third link pivotally connects the upper suspension arm to the wheel while having a shock absorber connecting portion to which the lower end of the shock absorber is connected. Further, the shock absorber connecting portion is disposed in the vehicle bottom position lower than an upper end surface of the in-wheel motor unit.

A two-speed transmission having two clutches for an electric vehicle includes an electric motor, a middle shaft, a first clutch, a second clutch, a first gear assembly and a second gear assembly. The electric motor includes a spindle. The first and second clutches are furnished on the middle shaft coaxially. The first gear assembly is furnished on the spindle and the first clutch respectively to generate a first gear ratio. The second gear assembly is furnished on the spindle and the first clutch respectively to generate a second gear ratio different from the first gear ratio. When the first clutch is activated to connect with the middle shaft, the second clutch separates from the middle shaft, and the electric motor outputs a first torque corresponding to the first gear ratio to the middle shaft. Similarly, the electric motor outputs a second torque corresponding to the second gear ratio.
