One or more techniques and/or systems are disclosed for a new coolant tank that may also provide a structural element to the frame of the engine compartment. The coolant tank is comprised of a rear wall that also makes up a portion of the firewall in the engine compartment. A structural coolant tank component is engaged with the rear wall to form the coolant reservoir. The coolant reservoir can provide support to attach structural elements of the vehicle, and can also allow for improved space efficiency in the engine compartment. Further, improved access to the filling port is provided, while continued operation and desired function is maintained even at extreme vehicle tilt.

There is provided a straddle type vehicle including: an engine; a fuel tank configured to store fuel to be supplied to the engine; a power generator driven by the engine; a regulator disposed below the fuel tank and configured to adjust electric power supplied from the power generator to a battery; and a regulator cover that includes a side wall covering the regulator on an outer side in a vehicle width direction and an upper wall covering an upper side of the regulator. The upper wall is formed below a side lower edge of the fuel tank to extend from an inner side to the outer side in the vehicle width direction with respect to the side lower edge.

A hybrid electric powerplant can include an electric motor configured to convert electrical energy into kinetic energy to turn a propulsor, and a heat engine configured to convert a fuel into kinetic energy to turn the propulsor. The powerplant can include a firewall disposed around at least one of the electric motor or the heat engine to create an electric motor fire zone and a heat engine fire zone separate from the electric motor fire zone such that the electric motor is protected against a heat engine fire, and vice versa.

A turbo shield with a slit, wherein the slit is configured to allow an inner diameter across the turbo shield to increase and decrease without altering the properties of fibers associated with the turbo shield.

The disclosed inventive concept allows an underlying component requiring servicing to be serviced without removing the heat shield entirely. The heat shield has two ends and an intermediate bendable area that allows it to flex, thereby giving the service technician access to the underlying component when only some of the fasteners are removed. The intermediate area of the heat shield is formed from a series of parallel and alternating ridges and grooves. The intermediate area of the heat shield is nominally flat and straight while the bellows are formed in the straight area by a process such as stamping. This combination of a flat and bellow enables the heat shield to be bent out of position and then restored to the original position after service. The heat shield may be entirely formed from a metal or the intermediate bendable area may be composed of a polymerized material such as rubber.

An object of the present invention is to, while forming a heat insulating layer on a squish area surface of a top surface of a piston main body, prevent generation of large cracks on the heat insulating layer and suppress damages and peeling of the heat insulating layer. To achieve this object, in the present invention, pressure is applied to a heat insulating layer provided on a top surface of a piston main body, that is, a pressing stress is applied to the heat insulating layer in advance.

The present disclosure relates to a generator for an internal combustion engine. The generator for an internal combustion engine includes: a heat protector configured to cover an exhaust manifold in which exhaust gas flows to absorb heat energy emitted from the exhaust manifold; and a thermoelectric module configured to be disposed on the heat protector to generate electric energy from heat energy absorbed by the heat protector.
